Abstract:
Anaerobic digestion is the biological degradation process of organic matter
under anoxic conditions, with production of methane and inorganic by-products,
including carbon dioxide.
Over the past years, many studies on anaerobic
digestion of the organic fraction of municipal solid waste (OFMSW) have been
carried out at laboratory, bench and pilot scale.
This work aims to summarize the
main features of the OFMSW anaerobic digestion techniques and to define the
state of art of this process in Europe, at both research and industrial level.
To this
end, main experimental results, design solutions and technologies are compared,
also in relation to capital and operating costs and data about full scale
experiences are reported.
Among the different aspects discussed, particular
interest has been provided to pretreatment possibilities in relation to substrate
biodegradability and biogas production rate.
The data collected and examined in
this paper stress the aspects to be improved, in order to define future perspectives
of the anaerobic process application for OFMSW treatment.
Keywords:
anaerobic digestion, organic fraction of municipal solid waste,
pretreatment.
1 Introduction:
The need to avoid direct landfilling of biodegradable residues is shared by the
whole technical community.
In the European Union this statement has been
recognized since the promulgation of the Council Directive 1999/31/EC on
waste landfilling which, as part of the measures undertaken to improve the
sustainability of waste management, forced member states to reduce the amount
