Biorefineries oleochemical biorefinery

The biorefinery scheme was developed initially for carbohydrate-containing feedstocks. Large biorefineries are currently operating in the USA (e.g., Cargill at Blair, Nebraska) and in Europe (e.g., Roquette Frs. at Lestrem, France). The concept can be extended to produce chemicals from other renewable feedstocks. An integrated production of oleochemicals and biofuels can be achieved in biorefineries using vegetables oils as main feedstock to produce versatile platform mole-... 

Type of raw materials used whole crop biorefineries (W CBRs), oleochemical biorefineries, lignocellulosic feedstock biorefineries, green biorefineries, and marine biorefineries.

Current oilseed biorefineries (see Figure 17.4) mainly produce food and feed ingredients, and biodiesel and oleochemical products from oilseeds, such as rape, sunflower and soybean.
