1 · What it gives

Cellulosic ethanol is a second-generation biofuel intended to replace ethanol from food crops (1G) and fossil transport fuels. The process has four steps: pretreatment, enzymatic hydrolysis, fermentation and distillation. The technology reached pilot and initial commercial demonstration, with key commercial-scale plants starting operation between 2013 and 2016.

D3	Bioethanol as fuel and octane/oxygenate instead of MTBE, high-aromatic petrol and fossil petrol Replaces: MTBE and ETBE oxygenates (groundwater pollutant), aromatics (benzene, toluene) used for octane, lead anti-knock legacy; part of fossil …	FUEL
D3	Enzymatic high-fructose syrup from starch instead of sucrose and acid hydrolysis Replaces: Cane and beet sucrose in beverages and processed foods; acid hydrolysis of starch for glucose syrup	FOOD
D2	Biodiesel, renewable diesel (HVO) and SAF instead of fossil diesel and heating oil Replaces: Fossil diesel in transport and generators; gas-oil heating; jet fuel (via SAF blends); also disciplines waste cooking oil and tallow that …	FUEL
D3	Biogas and biomethane from organic waste instead of firewood, charcoal, LPG and diesel Replaces: Firewood, charcoal and dung as cooking fuel (household air pollution); fossil LPG and natural gas for cooking and heat; diesel-generator …	FUEL
D1	Process equipment for residue-to-product plants — anaerobic digesters and biogas upgrading, composting turners and granulation lines, biomass pelleting, pyrolysis and carbonization kilns — instead of incinerators, landfill, open lagoons and open burning Replaces: Landfill and open dumping of organic waste; open burning of crop residues; open anaerobic lagoons; incineration of wet organic waste	EAC
D3	Sugarcane and palm-oil mill residues — vinasse, filter cake (press mud), bagasse, palm oil mill effluent (POME) and empty fruit bunches (EFB) — anaerobically digested, composted and returned to the field instead of raw discharge, open anaerobic lagoons, burning and mineral fertilizer Replaces: Raw vinasse dumped or over-applied on "sacrifice" fields; open anaerobic POME lagoons emitting methane; EFB and trash burning; part of …	SERV
