Biomasses
Biomass is a organic vegetal or animal material, whom is possible to produce renewable energy.
Every year, 1 wood hectare produce woody biomass equivalent to 8-25 Mwh of renewable heat able to heating a house.

Biological closed cycle
Wood saves energy: it is constantly growing back – with the CO2 in the air, water and the energy of sunlight.
Wood is CO2 neutral. When wood is burnt, only the amount of CO2 is released that the tree extracted from the atmosphere by means of photosynthesis during the course of its growth. The CO2 balance therefore stays level. If the timber were not used and left to rot in the forest, the same amount of CO2 would escape into the atmosphere.
District-heating network
District heating network is composed by an thermal central, whom produce heat, and by an distribution system, able to reach final consumers: schools, houses, companies…
Heat is distributed by hot water (90°), transformed thermal energy by plate heat exchanger.
Fiper thermal power station use to combustion only woody biomasses, to reach best efficiency.
2,3 Kg. woody biomass = 4 kWh Thermal + 1 kWh electric
District heating network fuels woody biomass, make positive community and environmental impact; in fact:
- town council achieve energetic autonomy
- local renewable resource encourage social cohesion
- local woody producer involvement assure a extra income and create new employment opportunity
