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

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
