Summary

From the beginning, the park has been designed to meet environmental and industrial ecology criteria. The park is formed by SMEs with high needs of management of waste generated and joint environmental management.

Some specific steps were done:

• 1. Identifying possible synergies in and outside the park.
• 2. Reuse of waste from some companies as raw material for others in and outside the park, evaluating at the same time economic, environmental and social impacts.
• 3. Disseminate this park model to be replicated in Martorell and other municipalities.

Public authorities predict five years since its establishment to obtain the estimated results.

Best practices key factors:

A: Meeting the demand

3 - the solution is identified as high strategic importance.

B: Successfully implemented

1 - the solution is implemented but so far, its impacts are limited or not known.

C: Cooperative approach

3 - the solution has been achieved through a joint approach of more than 5 organisations.

D: Replicability and scalability

3 - the solution demonstrates high potential for replication and/or is scalable.

Why is it a best practice?

From the beginning location, environmental, economic and social impact have been considered.

Summary

This industrial park has been developing eco-efficiency activities for more than 60 years. It is located in Harjavalta, a town with a prominent mining sector.

The main tenants are copper and nickel flash smelters (Boliden), a nickel chemical producer (Norilsk Nickel), an energy producer (Porin Lämpövoima), a hydrogen plant (AGA), a sulphuric acid plant (YARA) and the town of Harjavalta.

In addition to these major actors that established symbiotic exchanges (energy cascading and material flows) the site also incorporates the services of more than 100 subcontractors. Many waste,and by-products outputs are used as resources: heavy metals, sulphur, sulphuric acid, slag, wastewater, etc.

Best practices key factors:

A: Meeting the demand

3 - the solution is identified as high strategic importance.

B: Successfully implemented

3 - the solution is successfully implemented, and it has achieved significant environmental and economic benefits.

C: Cooperative approach

3 - the solution has been achieved through a joint approach of more than 5 organisations.

D: Replicability and scalability

1 - the solution is replicable and/or scalable, but only limitedly so (e.g. depends on boundary conditions).

Why is it a best practice?

This park is an example of different companies exchanging materials and energy following various combination of flows.
