INVOLVED AREA
Industrial-Urban Symbiosis
How did the idea come about ?
Because in the area there are the prerequisites
for developing projects with a view to industrial
symbiosis and circular economy.
─ The presence of thermal waste (heat otherwise
dissipated) and fuels deriving from the construction
of a waste treatment plant
─ The presence in the area of two "service plants"
─ The presence of an adjacent industrial area.
TAKING COOPERATION FORWARD 5
STAKEHOLDERS
• Service of waste collection, transport
and treatment
• Associates 57 municipalities, serving
up to 354,000 inhabitants
NET S.p.A.
• Revamping the organic waste
treatment plant, transforming
it into an anaerobic digester
with electricity, heat and bio-
methane production
TAKING COOPERATION FORWARD 6
INVOLVED AREA
The idea
New Udine plant allows
territorial sinergies
The plant center is a practical
example of integration between
circular economy, sustainable
mobility and industrial symbiosis
on which economically and
environmentally sustainable
synergies can be implemented
TAKING COOPERATION FORWARD 7
STAKEHOLDERS
• Manages water supply, wastewater
collection and treatment
• Serving 123 municipalities
CAFC S.p.A
• Interested in a better exploitation of the excess heat of the
cogenerator
TAKING COOPERATION FORWARD 8
PILOT PROJECT FIRST STEP
• Heat Exchanger (HE): recover waste
heat to satisfy heat needs
• Cogeneration (CHP): heat and power
production from biogas
• Waste mass flows: waste to feed anaerobic digestion
CAFC + NET symbiosis
TAKING COOPERATION FORWARD 9
STAKEHOLDERS
• Total surface area 150,000 square
meters
• 30 companies
UDINE MERCATI s.r.LI
• Interested in renewing its facilities to improve internal
logistic and reduce energy consumption
TAKING COOPERATION FORWARD 10
PILOT PROJECT SECOND STEP
• Absorption/Electric Chiller: heat
and electricity surplus converted
in cold energy
CAFC + NET + UDINE MERCATI symbiosis
• Cryogenic biogas upgrade:
synergy with cold energy
production
Cogeneration
Pre-treatment and
cryogenic upgrading
Digestate
TIMELINE OVERVIEW
Data collection• Visits to the plants
• Analysis of technical documents
Scenario identificationIdentification of best feasible scenarios based on
different synergies combination possibilities
Businness model draft• Business model structuring
• Technical economic environmental
assessment solutions identification
Technology identificationWaste recovery and energy efficiency oriented
technologies
Preliminary solution• Technical economic environmental assessment
preliminary solutions identification
• Solutions’ strength and weaknesses identification
Decision support system
development• Multi-objective modelling
• Scenario simulation
• Best compromise solution identification
TAKING COOPERATION FORWARD 12
LESSONS LEARNED
• Bottom up approach is fundamental to create
circular economy chains
• The pilot project is a good practice aimed at
recovering waste energy in line with circularity
principles
