resumo
In waste processing facilities equipped with mechanical
biological treatment (MTB) systems, the municipal solid waste
(MSW) is typically separated in organic residues, recyclable
waste and rejects. The organic fraction is then treated by
anaerobic digestion, obtaining biogas and a compost that can be
used in agriculture. However, the current waste management
legislation in Europe and the expected developments regarding
the coming directives on the application of the “End-of-waste”
criteria, are leading to barriers on the use of fertilizers resulting
from waste [1]. Within this context, the current work proposes
an alternative strategy to the valorisation of compost, through
the production of high-added value materials to be used in
catalytic processes. To this aim, a compost obtained from a MTB
plant for MSW was considered in the formulation of
carbonaceous materials prepared from glycerol, a low-cost byproduct
obtained in biodiesel production [2]. The composition
of the compost used is summarized in Table 1. As can be
observed, the content in organic matter is roughly 50%.
