Colloidal Silica Medium, to Obtain Safe inert, from RICE husk ash (COSMOS-RICE)
Date du début: 1 janv. 2013, Date de fin: 31 déc. 2015,
Background
In municipal waste incinerators, the main waste product is bottom ash, which is equivalent to some 10% by volume of the solid waste input. Fly ash, or the finest, lightest residue, is collected in many plants using a filtration system. Fly ash contains heavy metals (including zinc, lead, cadmium and chromium) and is therefore classified as toxi ...

COlloidal Silica Medium to Obtain Safe inert: the case of incinerator fly ash (COSMOS)
Date du début: 1 janv. 2010, Date de fin: 1 janv. 2013,
Background
Some 20-25% of the municipal solid waste produced in the EU15 around 2008 was treated by incineration, in over 400 installations. One of the important by-products of this process is fly ash. Recent projects have looked at ways of treating and re-using this ash. At the University of Brescia, a new fly ash treatment process, based on colloidal si ...
