Biomass fired boilers( furnaces) is more environmentally friendly than other fuels. If it's a waste product of industry, burning it avoids sending it to landfill—so it's doubly good for the planet.

What is biomass?
Biomass is a fashionable, fancy word that really just means plants (or other once-living things) used as fuel (especially ones grown specifically for that reason). Wood fuel gathered by people in an African country is biomass; ethanol, used to make diesel for car engines, is also biomass; and chicken manure used to fire power plants is biomass too. The great thing about biomass is that it's a kind of renewable energy: plants grow using sunlight, which they convert into chemical energy and store in their roots, shoots, and leaves. Burning biomass releases most of that energy as heat, generate electricity, and fuel our vehicles.
Biomass is more environmentally friendly and sustainable than fuels such as coal for three main reasons.
1.Unlike coal (which takes many millions of years to form from plant remains), biomass can be produced very quickly and we can easily grow new plants or trees to replace the ones we cut down and burn (in other words, biomass can be genuinely sustainable).
1.Plants absorb as much carbon dioxide from the air when they grow as they release when they burn, so in theory there is no net carbon dioxide released and burning biomass does not add to the problem of global warming. (That's why biomass is sometimes called a carbon neutral form of energy.) I say "in theory" because in practice growing, harvesting, and transporting biomass may use energy and that reduces the overall environmental benefit.
3. Biomass is often simply wasted or sent to landfill. Burning something like waste wood off-cuts from a lumber yard or chicken manure from a poultry factory not only gives us energy, it also reduces the waste we'd otherwise need to dispose of.
