Biomassapolttoaineita, or biomass fuels, are organic materials derived from recently living organisms. These fuels are a renewable energy source, meaning they can be replenished naturally over a relatively short period. Biomass can be used for heating, electricity generation, and even transportation fuels.

Common forms of biomass fuels include wood and wood waste, agricultural residues such as straw and corn stover, energy crops grown specifically for fuel, animal manure, and organic components of municipal solid waste. The conversion of biomass into usable energy can occur through various processes, including direct combustion, gasification, anaerobic digestion, and fermentation. Direct combustion involves burning biomass to produce heat, which can then be used directly or to generate steam for electricity production. Gasification converts biomass into a synthesis gas (syngas) that can be used to produce electricity or fuels. Anaerobic digestion breaks down organic matter in the absence of oxygen, producing biogas rich in methane, which can be used for heating or electricity. Fermentation, typically used for crop-based biomass like corn or sugarcane, produces ethanol, a liquid fuel for transportation.

The sustainability of biomass fuels depends on responsible sourcing and management practices. When harvested sustainably, biomass can be carbon-neutral, as the carbon dioxide released during combustion is offset by the carbon dioxide absorbed by the plants during their growth. However, unsustainable harvesting can lead to deforestation and habitat loss. The use of biomass fuels is part of a broader strategy to reduce reliance on fossil fuels and mitigate climate change.
