Environmental and agronomic impact of fertilization with composted organic fraction from municipal solid waste

(in lingua inglese)

In the studied environment, composting may reliably contribute to both restore soil organic fertility and solve the Naples waste problem within the perspective of a recycling economy. Annually, Naples city produces 1,500,000 tonnes of MSW with a 30% organic fraction; this would produce about 500,000 tonnes year−1 of compost. At a maximum rate of 30 tonnes of compost h −1 it would be possible to amend about 16,000 ha of agricultural areas, out of 42,000 in the Naples province and of 400,000 ha in the Campania Region, available for compost amendment (arable land, fruit crops, abandoned areas).
