Biogenic & Renewable Fuels: Case Studies & Testimonials

Why we prefer feedstocks from waste rather than purpose-grown resources

Although feasible technically, various feedstocks can be converted into a variety of usable fuels, we don’t usually support purpose-grown crops used for biofuels. Waste-based materials, whether biogenic (like biomass) or fossil (such as the calories embodied in plastics) or a mix (such as in rubber tires that contain quite a lot of natural rubber), better to rely on recovering resources than using land for generating crops for industrial purposes. Such use (exceptions are rapeseed/canola for diesel, perhaps miscanthus, giant reeds, sugarcane, and jatropha, but certainly not GMO corn), when operating at appropriate scale, often compete with land use decisions for arable cropland as food production. Until the planet is food secure, this practice is not recommended.
