Waste management and Circular economy / sustainable production and consumption

composting organic waste (Bio-waste):
Composting plant (Autonomous Public Utilities State Corporation in San Giovanni)
The aerobic composting plant with forced ventilation through the use of biocells currently consists of 12 elements operating on a cycle. Each biocell is served by an autonomous aeraulic system consisting of a fan, biofilter on a woody matrix, channels and connection valves.
The maturation of the compost is completed by mechanical turning of the piles made upon the yard, this phase requires a further period of about 2 months. The entire processing cycle requires a period of 3 months.
The plant is currently sized to process a quantity of waste equal to 1,400 ÷ 1,500 ton/year corresponding to the quantity of wet waste currently collected. The Autonomous Public Utilities State Corporation intends to extend the collection of organic waste to all users in the area. This activity will have important positive side effects for what concerns the disposal of the undifferentiated fraction, which will be reduced in quantity and will have better characteristics for the purpose of energy recovery (higher Lower Heating Value – LHV).
