16,540 tons of compost produced in 2019

The underlying principle is to reproduce, in controlled situations, the natural biological process of decomposition of the organic substance contained in waste, by the micro organisms present in the environment. The result, after a variable length of time, depending on the type of process adopted, is precisely compost. This is how a waste material of the production chain or civil consumption becomes a new resource for the first stage in the agricultural chain.

The composting plants managed by Acea Ambiente are in Aprilia, the largest in Lazio, in Sabaudia, both in the province of Latina, in Orvieto and in Monterotondo Marittimo, the largest anaerobic digestion plant in Tuscany:  quality compost is produced both through the recovery of material from the treatment of municipal waste and through the recovery of sludge from the purification of water.

Acea Ambiente in fact also carries out a series of other activities that complement the management of the Integrated Water Service (Acea Acqua). More specifically, the integration of the two sectors takes concrete form in the recovery and disposal of sludge deriving from the purification of water. These activities are entrusted to Aquaser, a subsidiary of Acea.

Aquaser: logistical management of approximately 580,000 tonnes of waste.

Aquaser transports the sludge from the wastewater treatment plants, managed by the companies part of the Acea Group responsible for the Integrated Water Service, to the composting plants (owned by Acea Ambiente and third parties). Here the sludge is used mixed with other matrices entering the plants (OFMSW, green waste, other organic waste) and sent for the production of quality compost for agricultural use.

The plant extension including an anaerobic digestion section for organic waste that produces electricity and heat was completed in November 2019. The extension of the plant and the construction of an anaerobic digestion section that produces electric and thermal energy, was completed in November 2019. The plant, which opened in December, has an overall capacity (existing section + new section) of 120,000 t/year. The three cogenerators installed, with a total power of 2.8 MW will enable production of approximately 23,000 MWh/year of electricity

The Sabaudia composting plant mainly processes sludge produced in the Acea spa group treatment plants, in addition to other waste and sludge of agricultural food origin. The plant alsohas a liquid waste treatment section with a potential of 30,000 t/year.

Estimated compost production

The composting plant in Monterotondo Marittimo, which has recently been revamped, is one of the largest in central Italy. It benefits from the most advanced technologies on the market and thanks to the use of combined anaerobic and aerobic technology, it has the capacity of processing 70,000 tons of waste per year (organic fractions, cuttings and prunings, and sludge), producing a total of approximately 6 GWh of electricity per year.

The plant offers notable environmental benefits, including reducing the amount of organic waste sent to landfill, which is instead transformed into useful fertilizers for agriculture (compost), and the production of electricity from renewable sources, by turning the biogas produced by the anaerobic waste digestion process into energy.
