Green Machine to Turn Waste Heat to Electricity
Posted on Tuesday, January 12, 2010 posted by posted by Mak @ 12:02 AM
An American invention that turns waste heat into electricity by operating like a "super-kettle", has been licensed by a Scottish energy company, which aims to turn over £40 million within the next three years by manufacturing the devices for the European market. Thistle Energy – a spin-out company from family-owned Thistle Generators in Bothwell, Lanarkshire – will initially sell Electra Therm's
"green machine" in the UK but also has plans to assemble it in Scotland before the end of the year.
The green machine is designed to work on industrial machinery that runs round the clock, such as generators or incinerators that give off waste heat.The device operates in a similar way to a kettle on a stove. Waste heat from industrial machinery boils a fluid inside the device, which in turn drives a generator to produce electricity.That could then be fed into the National Grid and sold at a profit or, in the offshore market, could be used to power operations such as accommodation barges.

Energy-efficient Bioconversion to Turn Waste Glycerin to Biofuels
Posted on Monday, January 4, 2010 posted by posted by Mak @ 10:17 PM
A large part of the glycerin glut comes from biofuel refineries, which put out enormous quantities of crude glycerin as a byproduct.
Glycos Biotechnologies, Inc. , which is commercializing glycerin-gobbling microorganisms developed by researchers at Rice University. The hungry bugs are at the heart of an energy-efficient bioconversion process that turns
waste glycerin into fuels and other products.
GlycosBio’s approach is to integrate bioconversion into individual refinery operations. Instead of a liability, the waste glycerin can be made into a profit center, yielding high-value chemicals (alcohols and acids) that can be used to make fabrics, insulation, and food products, as well as additional fuels. Other researchers have been developing ways to convert glycerin into ethanol, methane, hydrogen gas, and even a non-toxic antifreeze.
GlycosBio designed its operations to follow familiar refinery processes, which makes integration relatively easy. The big difference is the company’s proprietary microbe based conversion process, which requires far less heat and power. In addition to crude glycerin, the conversion process can also work on a variety of biofuel feedstocks, perhaps including algae.

Dutch Breakthrough in Bioethanol Production From Agri Waste
Posted on Tuesday, November 24, 2009 posted by posted by Mak @ 3:22 AM
With the introduction of a single bacterial gene into yeast, researchers from Delft University of Technology in the Netherlands achieved three improvements in
bioethanol production from agricultural waste material.
The invention is enthusiastically summarized by the principal researcher Jack Pronk: ‘In the laboratory, this simple genetic modification kills three birds with one stone: no glycerol formation, higher ethanol yields and consumption of toxic acetate’. For the potential billion liter ethanol gain to be realized, follow-up research on the transfer of this concept to industrial yeast strains and real-life process conditions is required. The Delft yeast researchers, who applied for a patent on their invention, hope to intensively collaborate with industrial partners to accelerate its industrial implementation.

Nanotechnology Could Reduce Costs of Cellulosic Ethanol?
Posted on Wednesday, October 14, 2009 posted by posted by Mak @ 12:26 AM
Cellulosic ethanol is an exciting technology which promises to convert the abundant sources of organic
waste worldwide (kitchen waste, yard waste, paper industry waste, etc.) into green alternative fuel.
The traditioinal production process of
cellulosic ethanol involves breaking down the cellulose into smaller units (hydrolysis reaction) on pretreated lignocellulosic materials followed by fermentation and distillation.The hydrolysis can be achived by using either acids or enzymes to breakdown the pretreated cellulosic biomass.The process of using enzymes for hydrolysis has been more expensive than the other approach, as the enzymes cost a lot of money, and typically a significant portion are lost during the cellulose degradation.
Researchers from the Louisiana Tech University have developed a way of immobilizing the enzymes, greatly reducing enzyme loss and its corresponding costs. Details on the new approach are scant other than that it uses "nanotechnology", but it seems likely that it employs some sort of charged particles to affix the non-catalytic domains of enzymes to reactor walls or a porous network, or else uses extracellular matrix proteins to bind the enzymes.
The university estimates that a commercial plant would save approximately $32M USD (they did not specify if this was a yearly total or perhaps over the plant's lifetime) and that under the federally established goal to reach 16 billion gallons of cellulosic ethanol, the net saving could be $7.5B USD, if the goal was reached. LTU also notes that they estimate cellulosic ethanol to reduce carbon emissions by 89 percent over traditional fuels.

Plastic-to-oil Converter: A Breakthrough in Green Technology
Posted on Thursday, October 8, 2009 posted by posted by Mak @ 2:10 AM
A breakthrough in green technology arrived in Montgomery County,United States as Evion Inc. unveiled its plastic-to-oil conversion technology.Envion said the facility was its first market-ready commercial unit and it was capable of converting any type of plastic
waste into high quality, synthetic light medium oil for less than $10 per barrel. The company estimated that the technology, which it calls the Evion Oil Generator, could turn one ton of waste plastic into approximately four 42-gallon barrels of high quality, synthetic light to medium oil. That oil in turn could be used to produce gasoline, diesel fuel, jet fuel and kerosene.
In addition to adding to use oil production Envion said that its technology could reduce landfill use and expense. Envion estimates that the United States produces approximately 50 million tons of plastic waste per year, with most of its heading for landfills. The company estimates its plastic-to-oil conversion processing cost at approximately $17 per ton, much less than the $70-$200 cost range of landfill disposal.

Generating Electricity from Passing Cars
Posted on posted by posted by Mak @ 1:45 AM
The first practical test of an innovative technology to generate electricity was conducted by Innowattech and the Technion - Israel Institute of Technology.The test was accomplished by drivers passing through the Hefer intersection,Israel, without even realizing it.They
generated electricity while driving over a ten-meter strip of asphalt,underneath which lie generators capable of producing some 2,000 watt-hours (Wh),the power was relayed to batteries situated beside the road.
The technology is based on piezoelectric materials that enable the conversion of mechanical energy exerted by the weight of passing vehicles into electrical energy. As far as the drivers are concerned, the road is the same.Edery-Azulay added that expanding the project to a length of one kilometer along a single lane would produce 200 KWh, while a four-lane highway could produce about a MWh - sufficient electricity to provide for the average consumption in 2,500 households.
If the pilot test is successful, the project is expected to be expanded. Generators will be situated in one-kilometer strips along Israel's highways.

New Technology Turns Plastic Waste into Oil
Posted on Wednesday, September 23, 2009 posted by posted by Mak @ 3:15 AM
The
Envion Oil Generator,United States, has recently assembled the first of its fuel-producing generators at the Derwood waste facility, which can consume any type of plastic and convert it into a light-brown synthetic oil that can be converted into fuel for a truck or a jet airplane.
The District company's technology works by melting plastic in an oxygen-free environment to separate the hydrocarbons destined for the oil barrel from the additives used to make that Big Gulp cup. The additives are rendered into a nonhazardous ash byproduct, the company says. While other firms have developed ways to convert
waste plastic into oil, Envion uses a "far-infrared ray" technology that yields more fuel than competitors' processes.
The generator, with a capacity for handling more than 6,000 tons of plastic per year, is a slightly smaller version of what Envion will soon be pitching as its flagship product. The 10,000-ton version, which could produce up to 60,000 barrels, costs $6 million to $7 million to build. Depending on the type of plastic, one ton can be converted into three to six barrels of fuel. Envion said it costs about $10 to convert the plastic waste into a barrel's worth of synthetic oil; currently, crude oil sells for close to $70 a barrel.

WindAir -A New Renewable Energy Invention
Posted on Friday, September 18, 2009 posted by posted by Mak @ 10:39 PM
EarthSure, a renewable energy company and innovator in alternative energy sources has developed a renewable energy technology called WindAir,a system for transforming the exhausted air flow from central air conditioning units into a source of renewable, clean energy (electric).
The WindAir system uses the warm air flow from the exhaust of a traditional air conditioning unit and drives it into a secondary fan turbine system. This secondary system has an electric-generating mechanism that transforms the wind flow into free, clean, renewable energy which is then inverted into the electric meter of the home or office building. This renewable energy has the capability to reduce the increase in electric used by the air conditioning system by generating enough electricity to send it back to the meter, thereby turning the air conditioning unit into an actual "sub-power station".The unique WindAir converter system can be incorporated into any existing air conditioning condenser unit or manufactured as a complete new unit.

New Method to Produce More Efficient Fuel from Waste
Posted on Thursday, July 30, 2009 posted by posted by Mak @ 10:39 PM
Researchers at the University of Illinois have developed a new effective and environmentally friendly method, which uses electrolyzed water instead of harsh chemicals in the pretreatment of ethanol
waste products to produce an acetone-butanol-ethanol fuel mix.
When ethanol is produced, distiller's dried grain with solubles (DDGS) is a waste product.The glucose in DDGS is stuck together, forming cellulosic corn fiber, but the structure is very tough. It forms a kind of crystalline structure which is very difficult to break.In order to get the glucose out, normally people use a strong acid such as sulfuric acid, or a strong lime base, to loosen it, making holes in it. Once the structure is destroyed, we use enzymes to cut the chain of glucose to get glucose that can be used for fermentation.
The strong sulfuric acid method produces some toxic compounds, which can kill the microbes that produce acetone-butanol-ethanol mix completely.Using alkaline sodium hydroxide as a base, after 60 hours, the acetone-butanol-ethanol production was also relatively low. But using acidic electrolyzed water, at about 20 hours the fermentation process began producing the acetone-butanol-ethanol mix. This new technique also eliminates the detoxification of the traditional acid method.The other advantage of this method is that the traditional method produces a large quantity of solid waste that needs to be handled, and some sugars get consumed in the process as well. We want to maximize the sugar yield so we can maximize the ethanol yield.

Gills Onions, one of the largest processor of fresh onions, has built an
anaerobic digester system at its Oxnard, California facility, which will help the company convert the hundreds of thousands of pounds of onion waste into electricity to power the plant.
Presently the company produces over 300,000 pounds of onion waste each day, which is utilized by the system to generate electricity, enough to power 460 homes. The electricity generated is stored in two 300KW fuel cells, which will also offset 30,000 tons of CO2 from entering the atmosphere each year.
The system will also help save the company $700,000 in electricity costs each year. Since the company is generating electricity for itself on site, it is also eligible to receive $2.7 million from Southern California Gas Company.

New Green Energy System to Capture Waste Energy
Posted on Wednesday, June 17, 2009 posted by posted by Mak @ 7:11 PM
A European supermarket chain, Sainsbury's is going to open its first "people-powered" store at its new store in Gloucester, using technology which captures energy from vehicles to power its checkouts.
Whenever a vehicle passes over the "kinetic road plates" positioned in the car park, energy is captured which would otherwise be
wasted. Sainsbury's will channel the energy back into the store, saving power that would normally be taken from the National Grid.
The kinetic road plates are expected to produce 30kW of green energy an hour, which is more than enough to power the store's checkouts. The system, pioneered for Sainsbury's by Peter Hughes of Highway Energy Systems, does not affect the car or fuel efficiency, and drivers feel no disturbance as they drive over the plates.

New Powerful Laser System Could Create Fusion Energy from Waste?
Posted on Monday, June 15, 2009 posted by posted by Mak @ 11:46 PM
Scientists at the Lawrence Livermore Lab are putting the finishing touches on the world's most powerful laser system known as NIF (National Ignition Facility). In about 18 months, physicists will conduct a highly-publicized test to create fusion energy from water. It is part of a project designed to take the world beyond nuclear energy. But if it succeeds, the system could do more than create energy in a new way. It might actually rid the world of
leftover nuclear waste in the process.
The NIF team will fire nearly 200 individual laser beams generated by an accelerator the size of a football field. The beams converge on a single target chamber containing a capsule of hydrogen. The hope is to compress it, and creating a subatomic reaction called fusion, ultimately igniting a controlled version of the same thermo-nuclear combustion that takes place on the sun.
As hydrogen is compressed, it releases particles called neutrons, which can penetrate the nucleus of another atom. So now we could take nuclear waste and use those neutrons to bust it up, get energy and remove the waste.

ORegen : New Device for Capturing Waste Energy
Posted on Thursday, June 11, 2009 posted by posted by Mak @ 1:22 AM
At GE’s Global Research Center near Munich, Germany, scientists have developed a new waste heat recovery technology called ORegen — which is a device that converts
waste heat from exhaust streams generated by equipment such as small gas turbines and industrial processes into usable electricity.This technology can help customers address the challenges of rising fuel costs and the increased demand for more efficient, environmentally friendly power systems and industrial plants.
They have modified
Organic Rankine Cycles (ORC) - an old technology which can use lower heat input temperatures.Therefore, heat recovery now offers a great opportunity to conserve fuel by productively using waste energy to reduce overall plant energy consumption and simultaneously decrease CO2 emissions. For example, when an ORegen (Organic Regenerator) unit is joined to GE Oil & Gas’ PGT25 gas turbine, it can provide up to an additional 25 percent more power on top of the output of the turbine itself.

OIT Students Look At Ways to Clean Waste Vegetable Oil into Fuel
Posted on Tuesday, June 9, 2009 posted by posted by Mak @ 3:28 AM
Aaron Findley, a student at Oregon Institute of Technology in Southeast Portland, has devised a way to filter and clean used
vegetable oil for use in cars and trucks that run on diesel.The project, called the automated biodiesel reactor was one of many student presentations featured at OIT’s 2009 Student Project Symposium. A wide array of renewable energy, information technology and mechanical engineering projects were included.
However, the project is in the early stages, which can produce about 25 gallons of biodiesel at a time. The system separates glycerol from the used
vegetable oil in one tank and then further cleanses it in an adjacent tank.The end product would be high-grade biodiesel that meets national American Society for Testing and Materials standards. The energy needed to run the biodiesel reactor would come from solar panels.The advantages of this biodiesel reactor is that it would be far cheaper than others on the market, which cost around $200,000.

Microbial Process Turns Urban Waste into Biodiesel
Posted on Wednesday, June 3, 2009 posted by posted by Mak @ 8:17 AM
A group of Spanish developers has developed a biochemical process called Ecofa to turn urban solid
waste into a fatty acid biodiesel feedstock. Eventhough using microbes to convert organic material into energy isn’t a new concept, using bacteria to convert urban
waste to fatty acids, which can then be used as a feedstock for biodiesel production, is a new twist here. It is based on metabolism’s natural principle by means of which all living organisms, including bacteria, produce fatty acids.
Two types of bacteria are under further development by Biotit Scientific Biotechnology Laboratory in Seville, Spain: E. coli and Firmicutes.They are also working on other types of bacteria that are capable of producing fatty acids with the same characteristics as biodiesel, which would eventually allow producers to skip the transesterification step.This technique can be extended to other organic debris, plants or animals.It is only necessary to find the appropriate
bacteria.
According to the group, they can produce between 1-2 liters [of biodiesel] per 10 kilograms of trash. That’s a little more than one-fourth to one-half of a gallon for every 22 pounds of trash—or between 24 and 48 gallons per ton of urban waste.They are working to improve that.

Biofuel from Waste Fats
Posted on Monday, May 25, 2009 posted by posted by Mak @ 2:56 AM
UK based biofuel manufacturer, Amplefuel is set to produce 40 million litres of biofuel each year, focusing on making it from used
cooking oil and solid fats.The plant, which utilises a variety of feedstocks from waste products, is one of a handful of firms that is able to break the solid fats down to a liquid biodiesel that does not solidify to later cause blockages.
Amplefuel utilise the solid waste fats from cooking that end up in landfill. Around 500kg of this fat is sent to landfill each week from people’s cooking which they put into a container to let it solidify and then leave it with the rest of their rubbish.The plant breaks the solid fat down by heating it and cleaning it of any visible and emulsified water. The two main fats found in solid fat are separated, treated and then cleaned up again and impurities are filtered out. The result is a liquid diesel that is then blended with other materials to ensure it stays liquid at low temperatures, like normal diesel, which solidifies at around -15 degrees Celsius.

Two British scientists, John Watt and Philip Michael, have launched technology that will convert the controversial tonnes of waste-ash from Britain's coal-fired power stations into valuable minerals useful to industries including cement, car and aviation manufacturers.The first plant for
RockTron, which is now finished and on-line in Fiddlers Ferry coal-powered station in Cheshire, UK, will transform 800,000 tonnes of ash per year into five valuable minerals. It will also cut the cost of dumping the ash in land-fill sites.
The most significant of the so called eco-minerals are solid glass spheres called aluminio-silicates that could reduce CO2 emissions in cement making - one of the dirtiest processes - by an estimated 400,000 tonnes a year in Britain alone. Another by-product are hollow glass spheres that can be used by automotive and aviation industries to make lighter cars and planes.

The commercial prototype of the company's system, Patriot-1, is microwave technology that has an automated engineering process to provide a highly energy efficient, emission free way to convert a wide range of materials into energy.
The demonstration, conducted at the companys's research facility, transformed large amounts of scrap tires into diesel fuel, methane, pentane, butane, propane as well as combustible gases, and carbon ash. Patriot-1's technology can process other materials for the purpose of unlocking energy including; shale rock, tar sands, bituminous coal, heavy oil as well as the environmental hazards associated with municipal waste, tanker sludge, waste oil and dredged materials.
To address the economic viability for
waste treatment, the technology will maintain an energy efficiency of 1:50, a ratio at which a wide range of materials become commercially viable to convert to energy regardless of commodity costs.

Engineers at Oregon State University have made a major new advance in taking waste heat and using it to run a cooling system – a technology that can improve the energy efficiency of diesel engines, and perhaps some day will appear in automobiles, homes and industry.This heat-actuated cooling system, which will probably find its first applications by the U.S. Army, could ultimately be applied to automobiles, factories or other places where waste heat is being generated, and used to provide either air conditioning or electricity.
Conceptually, the system works somewhat like existing heat pumps, but it's powered by waste heat, not electricity. What makes the technology unique is the use of microchannel heat transfer components and an efficient "vapor expander" to provide high heat transfer rates and smaller, lighter and more efficient heat exchangers.

Power From Cattle Manure- An Alternative Energy Economy

Cattle manure and Alberta ingenuity are combining to produce a fledgling alternative energy economy.Two huge tanks with rounded, mushroom lids loom above the snowdrifts, the first glimpse of Alberta's oddest-looking electricity plant and also its greenest.About one megawatt of power flows out on the wires — enough power to run the next-door feedlot and turn on the lights in 700 homes in Vegreville and Two Hills.
The project starts with new technology invented by their company, Highmark Renewables, to turn cattle manure into biogas, a product similar to natural gas from the ground. Highmark calls it "renewable natural gas" (since there's an endless supply of manure) and with a little cleaning up, it could heat your home.Right now, Highmark burns its biogas to make electricity. The company has developed 40 secret recipes to turn almost any kind of organic waste — slaughterhouse waste, sugar beet waste, municipal sewage — into biogas.

Nuclear Waste To Carbon-free Energy

Physicists at The University of Texas at Austin have designed a new system that, when fully developed, would use fusion to eliminate most of the transuranic waste produced by nuclear power plants.The invention could help combat global warming by making nuclear power cleaner and thus a more viable replacement of carbon-heavy energy sources, such as coal.
The scientists propose destroying the waste using a fusion-fission hybrid reactor, the centerpiece of which is a high power Compact Fusion Neutron Source (CFNS) made possible by a crucial invention.The CFNS would provide abundant neutrons through fusion to a surrounding fission blanket that uses transuranic waste as nuclear fuel. The fusion-produced neutrons augment the fission reaction, imparting efficiency and stability to the waste incineration process.

A ton of rice husks contains the same energy as 415 liters of petrol, or 378 liters of kerosene. A few handfuls of rice husks can boil water in six to nine minutes. Best of all, the rice husks are usually free--from farms or waste dumps that surround rice mills--and it is more efficient than ordinary cookers. Belonio's stove reduces greenhouse gas emissions and eliminate toxic fumes inside the houses. Even the char left after burning can be recycled to use as fertilizers or bio-coal briquettes.

Sulphur Polymer Concrete From Hazardous Petroleum Wastes
Posted on Wednesday, January 21, 2009 posted by posted by Mak @ 9:33 PM
Sulphur-modified concrete, developed from petroleum wastes, will be used in installing a new series of pipelines and manholes in the sewerage system here, as developers believe it will provide better and long-lasting concreting solutions.
The substance, called Sulphur Polymer Concrete (SPC), has been manufactured from recycled wastes and has been viewed as an inexpensive and durable solution for the construction industry. The invention has also offered a new technique in managing hazardous wastes, generated by oil refineries, said Dr Abdul Mohsin O. Mohammad, director of research at the UAE University (UAEU).The production of SPC does not emit carbon dioxide.
The scientists have used sulphur - a by-product of the oil industry - fly ash - a by-product from the cement industry - and sand from the abundant sand dunes and stone quarries in the UAE.Extensive test results indicated that the SPC material had high compressive strength, low hydraulic conductivity and high resistance to permeation of water, sulphuric acid and salt solutions.

Garbage for Fuel & Construction- Breakthrough in Waste Management
Posted on posted by posted by Mak @ 8:06 PM
University of Utah civil engineer Lawrence Reaveley came up with a potentially brilliant new idea for disposing off the enormous amount of garbage generated on the planet each day, in the form of a new patent idea that claims plastics – which make up the majority of wastes worldwide – could be used for construction purposes, sound, or heat insulation, as well as for generating electricity through burning.The present invention relates to methods for reclaiming plastics and cellulose materials for use in a variety of applications, including as alternative fuel sources.
According to one embodiment of the invention, the cellulose and plastic materials are shredded or ground, and then blended together. The blended materials can then be fed to an energy converter, such as a combustion unit or a gasifier, where they are burned as fuel source or used to create synthetic gas.Or the Blended materials are heated or have a binding element added thereto. Such mixture is then compressed to form a desired shape or sized object, and that object can then be packaged, distributed, or used. The blended object can be used as a fuel source, or as a building, sound attenuation, or insulation material.
Basically, slabs made of plastic, either pressed together with fiberglass of metal rods (for resistance), or melted so that the plastic keeps the mixture together, could be used for insulating buildings both thermally and acoustically. If they are reinforced, the slabs could also be used as walls and other high-strain construction elements, and could even be employed as a structure for new edifices.

MKII- A Southern Invention Turns Sewage Algae to Oil
Posted on Tuesday, January 20, 2009 posted by posted by Mak @ 1:28 AM
A Southern invention that turns sewage algae into crude oil is now operational but commercial testing of it is still three months away.The machine, known as the MKII, replicates the way oil is created naturally by pressure and those working on the project say it is 10 years ahead of similar projects worldwide.The oil produced can be refined into petrol, diesel and aviation fuel.
Invercargill engineering firm BL Rayners Ltd and Christchurch recycling company Solvent Rescue Ltd have collaborated under the name Solray to develop the machine, which has taken them 18 years to perfect.Solvent Rescue owner Chris Bathurst said the MKII had been operating for the past four months after performing to expectation during its testing phase.
Sewage To Oil
* The machine uses high pressure to turn algae, grown in sewage ponds, into algal sludge.
* The sludge is then processed using pressure, temperature, timing and a secret catalyst to turn it into crude oil.
* The crude oil can then be refined into jet fuel (kerosene), petrol, methane, LPG, diesel, or bitumen.
*The sewage pond water is left clean enough to be re-used by industry.
* The algae absorbs carbon dioxide.
* The process replicates how oil is created naturally, but much faster.

UMass Team Promotes Microbial Fuel cell to Clean Up Waste
Posted on Monday, January 19, 2009 posted by posted by Mak @ 8:50 PM
A group of physicists and engineers at the University of Massachusetts Amherst propose a portable water closet that uses bacteria to clean up waste, eliminate odor and generate its own electricity.
The essence of the company is a particular strain of bacteria and an associated microbial fuel cell. According to Malvankar, a recipient of the Eugene M. Isenberg Award at UMass, the bacteria’s ability to generate small amounts of current made it useful, but only for certain applications.“It doesn’t generate enough energy to compete with wind or solar, and it isn’t really cost effective for waste water treatment,” he said. “But it works well in portable toilets, which are traditionally very unpleasing places.”
The system can produce enough power for the unit’s fan and light, according to Malvankar.Bug Power’s bacteria doesn’t break down all the waste, but Malvankar said that when dealing with porta potties, any reduction is an improvement.“If we can even reduce the servicing by half, it will be a huge savings for distributors,” he said.
While Bug Power’s application may be novel, the potential of microbial fuel cells is being looked at in several other local companies. Fall River’s Hy-SyEnce Inc. and Cambridge’s IntAct Labs LLC are applying the technology to generating large-scale power from waste water and industrial waste products. At Harvard University, a group led by researcher Peter Girguis is hoping the technology can help provide power for lighting and other systems in developing nations.

Petroleum Mixed with Wastewater Reduces Emissions by 84%
Posted on Monday, January 12, 2009 posted by posted by Ecacofonix @ 9:11 AM
Taiwanese scientists discovered that a new fuel can be made by combining industrial wastewater and petroleum oil. The new fuel’s efficiency is increased by 14% and is a friendly way to treat industrial wastewater as well.
Scientists from National Cheng Kung University mixed HFO (heavy fuel oil) with wastewater and burnt them together. By mixing 80% of HFO with 19.9% wastewater and 0.1% surfactant, the CO emissions are reduced by 84% compared to the emissions generated by burning standard HFO in the same boiler. The new fuel also drastically reduces other emissions such as particulate matter, nitrogen oxides, sulfur dioxide, and volatile organics.
How does this improvement come about? By adding wastewater to the oil, micro explosions take place prior to the ignition of oil, causing it to atomize into a fine vapor. This leads to a complete and also to a lower temperature combustion reducing pollution from nitrogen oxides.

Now, you might be excused for thinking what I'm gonna say is a pile of, er, poop, but not, this is true.
A company in Sri Lanka is making paper from elephant poop:
"Since an elephant’s diet is all vegetarian, the waste produced is basically
raw cellulose. Thoroughly cleaned and processed, the cellulose is
converted into a uniquely beautiful textured product, marketed as “Ellie
Pooh Paper”.
So, thus we have the company

New Biofuel Made of coffee grounds leftovers
Posted on Thursday, January 8, 2009 posted by posted by Mak @ 12:48 AM
Coffee and biofuels just became one. A team of experts from the University of Nevada have managed to obtain diesel fuel from coffee grounds leftovers.
It's not even hard to do, claimed the team, comprised of Mano Misra, a professor of engineering, Narasimharao Kondamudi, and Susanta K. Mohapatra. They stated having employed regular chemistry techniques both in order to extract the oil they needed for the process from the coffee grounds and to turn it into fuel. Also, the whole process did not require more energy than the typical fuel manufacturing, and the price of the biofuel was estimated at about one dollar per gallon (some 22 cents per liter).
Based on 50 pounds (23 kg) of material bought from Starbucks stores, their analyses indicated that some 10-15% of the coffee waste weight represented extractable oil. But obtaining the waste may prove harder than extracting its oil, since there are only a few places this could be bought from, such as the bulk roaster that the researchers will use for their program.But coffee won't be the next major breakthrough in fuel industry. Actually, all the coffee waste on the planet could only produce about 1% of the US diesel requirements for a year.

Plasma process converts garbage into clean energyFebruary 23rd, 2007
With an eco-friendly technology called Plasma Gasification, one can produce clean energy which in turn powers the process, along with commercially useful byproducts.
Recently a company has developed this interesting device that can handle pretty much any type of waste put into it and turn it into a clean source of energy.
This process creates two byproducts; one is a synthetic gas composed mostly of hydrogen and carbon monoxide which can be converted into a clean fuel. The second byproduct is a form of vitrified glass that can be used as inert fill for construction in roads, building blocks or other uses.
The process produces enough synthetic gas to power the unit, as well as a surplus which could be sold directly or used to generate excess electricity, providing an additional source of revenue for the facility.

Waste to Energy - Burning Turkey FecesApril 15, 2007
A revolutionary plant in USA is turning 270 tons of poultry waste into 300 barrels of crude oil every day. That would be cause for wild celebration in many circles if not for some problems. First, the plant is losing money, and second, some residents of the town that once welcomed it now pretty much hate it. It turns out that process of cooking turkey waste and other waste gives off - not surprisingly - a horrible stench.
Solution? The owner is considering a deal to build a plant in Ireland, where costs would be considerably less, and where a recent news article predicted a plant should be operating by next year.

Animal Fats into Jet FuelMarch 19, 2007
RALEIGH - Airlines could soon be looking to acquire chicken grease and hog lard to convert into jet fuel.
A team of NCSU scientists and engineers says it has developed a biofuels technology capable of converting animal fats - including lipids from dead chickens, hogs and cattle - into fuel for airliners and fighter jets.
The technology is "100 percent green," as no petroleum-derived products are added to the process. It can also be used to make additives for cold-weather biodiesel fuels and holds the potential to fuel automobiles that currently run on gasoline.

Halifax (CP) - A low-rise apartment building in Halifax heated with the help of human waste takes energy efficiency to new heights, says an engineer whose company was involved in the affordable-housing development.
Energy providers working on the new building started with the concept that sewage isn't useless material; Human waste from the four-storey building is pumped into a holding tank for six hours before it's released into the city's sewer system. during these six hours, a geothermal inside the tank takes the heat out of the sewage.
