biofuel
의미: A fuel derived from biological sources such as plant matter, vegetable oils, or organic waste, used as a renewable alternative to fossil fuels in transport and energy generation.
Biofuels are typically categorised by generation: first-generation biofuels come from food crops (rapeseed oil, sugar cane), second-generation from non-food biomass (agricultural waste, wood chips), and third-generation from algae. The UK blends biofuels into petrol and diesel under the Renewable Transport Fuel Obligation. Critics argue that first-generation biofuels compete with food production and can drive deforestation. It collocates with 'sustainable,' 'renewable,' 'mandate,' 'feedstock,' and 'blend.'
