Chapter VI - Biodiesel from Algae

This page provides details of the chapter VI, from the Comprehensive Oilgae Report. You can purchase this chapter alone using the payment button provided below.


Algae can be used to produce a variety of products which can be used as fuel. One such fuel is the Biodiesel. Biodiesel refers to any diesel-equivalent biofuel made from renewable biological materials such as vegetable oils or animal fats. While there are numerous interpretations being applied to the term biodiesel, strictly speaking, the term biodiesel usually refers to an ester, or oxygenate, made from the oil and alcohol. This chapter details the production of biodiesel from oil and the various steps involved in it.

Key Takeaways from the chapter

  1. Some of the prominent methods currently used for harvesting microalgae are filtration, centrifugation, flocculation and flotation.
  2. Harvesting microalgae is an expensive and energy intensive process and presents a key challenge, unique to the algae industry.
  3. While centrifugation and flocculation/flotation are expensive harvesting methods, both these are expected to have the most potential in future for harvesting microalgae.
  4. Methods suggested for efficient and cost effective harvesting are still in the research stage.
