What changes this industry: bio-solutions with evidence, technologies, suppliers and open money.
Overview of the industry
Fossil fuels and their toxic additives (MTBE, octane aromatics, the lead legacy), and the proven biological alternatives already running at national scale: biogas/biomethane from organic waste, sugar/starch/cellulosic bioethanol, biodiesel and renewable fuels.
Fuels, digesters and blending programmes need national authorization (excise, fuel standards, grid/pressure rules; in Russia: technical regulations on fuel quality, gas rules). The articles are overviews, not engineering or regulatory advice.
This is the first collection built with a direct join to the 1,320-company vendor index: 146 active companies carry the bioethanol/biogas/biodiesel-saf tags.

| ID | Problem → alternative | Replaces | Rating |
|---|---|---|---|
| EN01 | Cooking & farm power → biogas/biomethane from dung, food waste, agro-effluents | Firewood, charcoal (household air pollution), LPG, diesel gensets | Replace / Partial |
| EN02 | Octane & oxygenate → fermentation ethanol (sugarcane/corn/cellulosic/off-gas) | MTBE oxygenate, benzene-rich aromatics, part of petrol volume | Replace (component) / Partial (volume) |
| EN03 | Diesel & jet fuel → biodiesel (FAME), renewable diesel (HVO), SAF from waste oils | Fossil diesel (IARC Group 1 exhaust), heating gas-oil, jet fuel | Replace (blends/drop-in) / Partial (total demand) |
| EN04 | Landfill/dump methane → LFG capture, MSW-organics AD, biomethane/bio-CNG | Flared or vented methane, part of fossil gas | Replace (flaring/venting) / Partial (total gas) |
| EN05 | Solid biofuel → pellets/briquettes from agro-residues, co-firing | Coal/HFO in boilers and kilns; open-field straw burning | Replace (many boiler duties) / Partial (high-temp kilns) |
| EN06 | District heating → biomass boilers and CHP (Sweden >70 % biomass) | Heating oil and coal | Replace |

|---|---|---|
| Leaded aviation gasoline (100LL avgas) for piston aircraft | Lead exposure around small airports | Unleaded avgas replacements are synthetic (e.g. G100UL); no biological route |
| High-temperature industrial heat (>400 °C, cement/glass/steel) | Fossil CO₂ | Biomass/electrification partial; no full bio substitute at scale |
| Jet fuel demand in full | Combustion CO₂ at altitude | SAF is real but supply-constrained and costly — covered as Partial in EN03, not a “Replace” claim |
