«Demonstration of an integrated waste-to-energy system for energy
generation from biodegradable organic waste and wastewater»
INTER-WASTE: LIFE 08/ENV/CY/000457
The integrated INTER-WASET Unit
INTER-WASTE is a co-funded project by LIFE+.
The project is implemented in Cyprus under
the coordination of Cyprus University of
Technology and with the cooperation of
University of Nicosia, National University of
Athens, Proplan Ltd and the Environment
Service of the Ministry of Agriculture, Natural
Resources & Environment of Cyprus. The
project focuses on the innovative integration
of a Membrane BioReactor (MBR) System for
the treatment of municipal wastewater with
an Anaerobic Digester (AD) for the
subsequent treatment of the generated
sludge along with other biodegradable organic
waste (BOW) resulting in energy generation.

In the framework of Action 2, the MBR-AD unit
has been designed and constructed and finally
installed in Cyprus.
The integrated ‘INTER-WASTE’ Unit consists of
four main systems. These are:
System I : The Membrane Bioreactor System
System II : The Anaerobic Digestion System
System III : The Biogas Treatment System
System IV : The System for the Treatment of
Residues.
The MBR-AD Unit is capable of treating primary
treated effluent of municipal wastewater
through the Membrane Bioreactor System as
well as organic waste along with sludge through
the Anaerobic Digestion System. The produced
biogas is led to the Biogas Treatment System. In
this System, biogas is temporarily collected and
purified, and is then led to the Combined Heat
and Power (CHP) unit. Finally, through the
System for the Treatment of Residues,
generated digestate is processed.
The useful products generated from the Unit
are: (i) effluent of superior quality that can be
safely reused in agriculture, (ii) biogas suitable
for the generation of heat and power and (iii)
high quality stabilized solid product to be used
as soil improver.
