Strategies for resource recovery from the organic fraction of municipal solid waste

Autothermal Drying of Organic Fraction of Municipal Solid Waste

In order to take advantage of heat released during composting, the autothermal drying process requires the maintenance of adequate air flow combined with temperature. The aim of this paper was to construct a drying tunnel enabling the automatic control and regulation of the basic process parameters for biomass drying (organic fraction of municipal solid waste together with plant structural mate...

Thermochemical Pretreatments of Organic Fraction of Municipal Solid Waste from a Mechanical-Biological Treatment Plant

The organic fraction of municipal solid waste (OFMSW) usually contains high lignocellulosic and fatty fractions. These fractions are well-known to be a hard biodegradable substrate for biological treatments and its presence involves limitations on the performance of anaerobic processes. To avoid this, thermochemical pretreatments have been applied on the OFMSW coming from a full-scale mechanica...

Strategies for Separating Contaminants from Municipal Solid Waste Compost

separation approaches affect organic contaminant levels. Thus, this fact sheet will focus primarily on heavy metal contaminants. Those metals of greatest concern in compost—cadmium, mercury, and lead—can be harmful to animals and humans at relatively low concentrations and tend to accumulate in soil, plants, and animals. For most of these potentially harmful metals, the levels in MSW composts a...

Perspectives for Sustainable Resource Recovery from Municipal Solid Waste in Developing Countries: Applications and Alternatives

Alternative strategies for energy recovery from municipal solid waste Part A: Mass and energy balances.

This two-part paper assesses four strategies for energy recovery from municipal solid waste (MSW) by dedicated waste-to-energy (WTE) plants generating electricity through a steam cycle. The feedstock is the residue after materials recovery (MR), assumed to be 35% by weight of the collected MSW. In strategy 1, the MR residue is fed directly to a grate combustor. In strategy 2, the MR residue is ...
