European Bio-Energy Projects

AGROPTI-GAS
Objectives
Many cities are looking for vehicle fuels
and waste management systems that are
environmentally friendly and cost effective.
This full-scale system for co-digestion of
biological municipal waste and agricultural
feedstock will demonstrate a new way of
meeting these needs. A process technique
that allows a unique low water content will
enable a cost effective production and
distribution system.
The objectives are to demonstrate:
1. A process technique with components
to enable the co-digestion of easily
degradable, solid biomass as a
municipal, source-sorted, biological
waste with agricultural feedstock
2. Biogas being competitive as a vehicle
fuel and waste management system
3. The advantages for the farmer to be part
of the system.
AGROPTI-gas
Demonstration of an
optimised production
system for biogas
Challenges
• To demonstrate techniques for the co-digestion
of biological solid waste and agricultural
feedstock with minimised fresh water
addition/dilution
• To demonstrate how the integrated system
can contribute to a lower environmental impact
and sustainable resource management
• To demonstrate how an information and
communication forum will improve the mutual
understanding in integrated rural-urban cooperations
• To carry out the introduction of a system for
profitable production of renewable energy in
the form of biogas as a vehicle fuel
Project structure
In order to demonstrate and evaluate this novel
concept we have gathered a dedicated group
consisting of one municipality, different biological
and technical researchers and a regional
agricultural association. The partners come from
Sweden, Denmark, Germany and Bulgaria.
To structure the work that will be needed during
the project's different phases it as been divided
into nine work packages; Co-ordination,
Procurement, Building, Communication, Analysis
of socio-economic aspects, Dissemination,
Evaluation of the co-digestion process, Evaluation
of the rural-urban biogas system and Conclusions
with a final report.

Expected impact and exploitation
The AGROPTI-gas project will demonstrate a
novel concept for the profitable production of
renewable energy in the form of biogas as a
vehicle fuel. A full-scale system for co-digestion
of biological household waste and agricultural
feedstock will be built and the digested slurry will
be used as a natural fertiliser. By using novel
process techniques, including new components,
a unique low water content production and
distribution system can be achieved, which
optimises the whole system including logistics.
If the demonstration in full-scale proves
successful, the system has a large potential in
Europe with large environmental benefits as an
outcome. The environmental benefits are in the
form of decreased emissions of greenhouse
gases, improved air quality in the cities due to
cleaner vehicle fuel and optimal circulation of
nutrients with less need for artificial fertiliser.
