RDF/SRF Evolution And MSW Bio-drying

Abstract
In Europe the mechanical/biological treatment (MBT) is an increasing option as
a pre-treatment either before landfilling or before combustion. In this paper,
taking into account the new EU directives and in particular the Italian situation,
differences between fuel derived from MSW (RDF) and Solid Recovery Fuel
(SRF) are presented. In agreement with the new EU directives, RDF/SRF can be
produced from approaches based both on the one-stream plant concept and on
the conventional two-stream process. The first option refers to bio-drying. The
effect of different strategies of selective collection of MSW is analyzed in term
of characteristics of the residual MSW and its suitability to be converted into
RDF/SRF. The role of respirometry is discussed too.
Keywords: municipal solid waste, lower heating value, refuse derived fuel,
respirometry, selective collection, solid recovered fuel.
1 Introduction
The amount of municipal solid waste (MSW) has strongly grown in the last
decade and continues to do so worldwide. The mechanical/biological treatment
(MBT) is a term generally used for a number of waste management processes
such as material recovery facilities (MRF), refuse derived fuel production,
mechanical separation, sorting, composting and pasteurizing. Originally the
MBT-concept has been developed in the 80s in order to divide the waste stream
in wet fine fraction and dry coarse fraction. Later, with the introduction of
selective collection of the dry recyclable fraction and the development of the
waste-to-energy sector, MBT was presented also in the option treating the entire
waste stream for producing a fuel.
The aim of MBT is to minimize the environmental impact associated with
landfilling of biodegradable waste and to obtain additional value from waste by
