Industrial Symbiosis on the Island of Händelö
Michael Martin Environmental Technology and Management
Linköping University
Overview
• Händelö
• Industrial Symbiosis (Händelö-Norrköping)
• Bioenergy Complex
• Are there benefits?
• What if it was a fossil system?
• It can be better!
• Future Work

Industrial Symbiosis on Händelö
Exchanges of:
– Industrial By-products
– Agricultural By-products
– Waste (?)
– Energy
– Fuels
– Water

Bioenergy on Händelö
14
• 210 Million Liters of Ethanol/year
– For low blending in Sweden (5% ethanol in gasoline)
• 500,000 Nm3 Biomethane
• 27,000 Tonnes Waste from Norrköping
• Heat and Electricity to Norrköping
World leading grain based ethanol producer
Again… So what is unique about
Händelö?
Renewable Energy System
• CHP-Based on Renewable Fuel
• Heat and Electricity come from burning forest
industry wastes and municipal wastes
Other important aspects for system:
• Electricity from Swedish average system
• Biogas system receives “hot” product
• Cereals primarily from region
16 16
Leads to many benefits…
Integrated Case: Ethanol and
Biogas
• Changes and effects to the system based on one
by-product exchange
• Impacts from increasing by-product exchange
• Learn about modeling industrial symbiosis and
quantifying benefits

Industrial Symbiosis &
Biofuels
IS & Biofuels
• Introduction of Bioenergy Systems = Beneficial
• Many material and by-product exchanges
possible
• Biogas can be added to systems easily to
upgrade wastes/by-products
• Biofuel efficiency (energy & materials) can be
optimized by integration
• NO SUCH THING AS WASTES!
29 29
It can be better!
More synergies/exchanges
• Replace fossil fuels with biofuels
• Pipelines-Reduced Transport
• Process optimization
• Increase type and amount substrates
• Introduce a biodiesel plant…

Future Applications of Research
• What happens both economically and
environmentally?
• How can “benefits” and “impacts” be quantified
using the Renewable Energy Directive (RED)
guidelines?
• What implications does the RED have for
industrial symbiosis?
• How can introduing biogas to the system
upgrade/upcycle materials and wastes?
