Renewable fuels are bound to gradually replace fossil fuels. Development of biorefineries will mark the historic transition into a sustainable society in which biological feedstocks, processes and products constitute the main pillars of the economy. Energy policy facilitating the introduction of biofuels, including biodiesel, avails itself of taxation, subsidies and mandates, which are not always unquestioned. Transformation of vegetable oils to liquid fuels is achieved industrially by catalytic transesterification. Biodiesel manufacturing, as yet based mainly on rapeseed oil (Europe), soybean oil (US, Argentina, Brazil) and palm oil (SouthEast Asia), requires further feedstock development. Important actors in the biodiesel value chain are vegetable oil milling facilities and the crude oil industry. |
