These are alternative fuels
This includes not only the first generation biofuels currently on the market, but also advanced biofuels such as HVO/care diesel and others made from waste and residues from agriculture, forestry, the timber industry, the food industry and similar sectors . There are also fuels based on non-biological waste such as plastics and electricity-based fuels, so-called PtX fuels (Power-to-X) or e-fuels, and highly efficient hybrids, ie fuels that are based on residual or waste materials as well as also based on electricity (e.g. waste-based e-fuels).
