Material valorisation of wastes supposes separating them through different ways into valorisable components. Since separating already mixed wastes, and particularly household wastes, s only possible with great expenses ad is, in most cases, unsatisfactorily, we should use all the possibilities of selective collection of materials alone or per material groups before mixing it with other waste parts. In this respect, we suggest pre/selection at the waste source into two fractions: biodegradable ad valorisable.
