  • How is biodiesel made?
  • Biodiesel is usually obtained by transesterification of oils or fats by reacting a short-chain alcohol, like methanol, in the presence of a homogeneous base- catalyst (typically NaOH). The most common raw materials for production of biodiesel are vegetable oils from sunflower, soybean, oil palm and other (Knothe, 2005; Dias, 2008).
  • Could oily feedstocks be used for biodiesel production?
  • As a consequence, attention of the researchers is significantly turned to examining possibilities of new and cheaper oily feedstocks for biodiesel production, such as waste oily by-products from edible oil refinery (called here waste vegetable oils), waste animal fats (WAFs), waste cooking oils (WCOs ), and nonedible oils.
  • What is biodiesel & how does it work?
  • Historically, the term biodiesel has been used to refer to all types of alternative fuels such as vegetable oils, vegetable oils mixed with diesel oil, vegetable oil microemulsions, pyrolysis products of vegetable oils, methyl and ethyl esters prepared from vegetable oils or animal fat.
  • What is a biodiesel feedstock?
  • Diverse sources serve as biodiesel feedstock, including vegetable oils, animal fats, and microalgae oils. Comprehensive descriptions of each feedstock source are provided in the subsequent subsections: 2.1 (edible vegetable oils), 2.2 (non-edible vegetable oils), 2.3 (animal fats), 2.4 (waste cooking oils), and 2.5 (microalgae oils).
  • Is biodiesel sustainable?
  • Currently, biodiesel production has seen significant growth with numerous commercial plants operating worldwide, contributing to the blend of biodiesel with fossil fuels to reduce carbon emissions. Diverse feedstocks, including vegetable oils, animal fats, and waste oils, are increasingly used to enhance the sustainability of biodiesel production.
  • What technologies are used in biodiesel production?
  • Various technologies such as chemical (homogeneous and heterogeneous) and enzyme catalysis as well as non-catalytic processes have been applied in biodiesel production from waste oils, fats, and cooking oils. The future commercial process of biodiesel production will be a choice among solid catalysts, lipases, and non-catalytic processes.
