Bioethanol is widely used to be mixed with gasoline, since combustion of the mixture has many benefits:
- It is renewable and reduces GHG emissions, by more than 71% compared to a fossil fuel.
- Reduces other pollutants emissions, improving air quality.
- It is biodegradable and has low toxicity.
- Reduces dependence on imported fossil fuels, specially in Europe.
- Creates local jobs and economic growth in rural areas.
- Encourages farmers to boost productivity and reuse of abandoned land.
- Infrastructure changes are non-existent or minimal.
- Changes in vehicles are non-existent or minimal.
- Encourages new technological innovation in advanced technologies.
- Produces much needed high-protein.
- Reduce dependence on animal feed imports and other imported commodities.
The benefits confirm the importance of ethanol biorefineries for the EU’s efforts to combat climate change and compensate for its deficit in animal feed proteins. Of the total ethanol production in 2018, 82 percent was used as fuel, with an average of more than 71 percent GHG savings compared to gasoline, a reduction that increased for the seventh consecutive year.
Biofuels also help reduce emissions of polluting particles into the air. With higher levels of ethanol, the mixture has fewer particle emissions than fossil fuels. The oxygen content in ethanol helps improve combustion. Adding bioethanol to gasoline at higher levels, could significantly reduce the CO2, CO and HC emissions of gasoline vehicles.
