Italian design solves Euro waste problem

PILING

THE so-called Biocubi process patented by Italian firm Sistema Ecodeco is an aerobic biological processing for municipal refuse that produces a 'dried' combustible material from the putrescent elements in household waste.

An initial sorting process removes more obviously recyclable elements in the waste and then the waste is shredded and distributed across an aerobic f loor, which has a grid to allow air to be blown in underneath. The oxygen speeds up decomposition, which at the same time creates its own heat that dries and thermally sanitises the materials.

According to Ecodeco 'this bio-dried material is a new material whose components can be easily separated in accordance with material and energy needs'.

It is easily transported to final utilisation centres for burning or possibly re-use and materials recovery. Fractions taken to landfill have a lower environmental impact than other refuse. Burning can be done in industrial plant or in incinerators but with greater control than with raw refuse.
