In Italy the spread of biomass plants proceeds in fits and starts, yet the biomass can bring concrete benefits toenvironment and the balance sheet of the company that decides to outsource the business to a plant. The biomass plants, especially those who exploit as "fuel"The wood waste, could play a leading role in national energy production, thus breaking the bonds with coal sources.
The main sources of biomass include waste from agricultural, livestock or industrial activities. Let's see in detail:
- Waste from the agro-food industry
- Farm wastewater
- Urban waste
- Agricultural and forestry residues
- Pellets and other specially grown vegetables
When the biomass in question derives from municipal waste, there are many disputes to be addressed and we refer you directly to the article on the subject "Transforming waste into energy "There is often confusion between biomass plant and the plants that deal with the waste incineration. When it comes to biomass exclusive reference is made to waste of vegetable origin, the combustion of these does not produce pollution and environmental damage caused by the so-called "waste-to-energy plants " pointed out by the company as ecomonsters.
Before the spread of biomass plant, companies had to take the burden of paying for the disposal of the waste they produced. What until recently was seen as a cost to be incurred for the company, has now turned into a profit opportunity with the production of energy and access to specific incentives.
Biomass and environment
A biomass plant for not having a negative impact on the environment, it must be small and above all it must exclusively treat biomass locally grown. The plants a biomass must have as their purpose the treatment of a company's wastewater and not the production of energy: if the ultimate purpose is the production of electricity, the plant set up will be large in size and above all, it will use biomass that come from distant places or even specially produced, this implies large CO2 emissions for the transport of the biomass itself.
