Benefit For Switzerland
- Gain Resources And Reduce Environmental Risks
- About 10 % of the ferrous metals from the bottom ashes (52'000 t/a) can be extracted without pollutions and loss of oxidation, which means they will become important resource for steel production.
- The 3 % of Aluminum (ca.19'500 t/a) is an important resource as well. A huge amount of energy and CO2 can be saved with their extraction. 1 kg Al has the equivalent of 236’000 t of CO2.
- The recovery of valuable metals, such as copper, and alloys is further optimized. Their extraction is also highly desirable from an ecological point of view as their production generally demands a high energy along with other disruptive environmental aspects.
- If we succeed in integrating the de-carbonited calcium into the cement process, an important amount of CO2 and a lot of landfill capacity can be saved.
- The care and emission free storage of residues helps the environment, saves expensive landfill space and saves energy as well as money.
- The economic potential, basic know-how and knowledge helps to enter future markets in Europe and in other parts of the world.
Benefit For Our Partners
- Know-how And Prestige
- Every participant is part of the solution and has direct access to the results.
- Only in cooperation the demanding tasks can be worked out efficiently. Cooperativeness is a benefit for every participant.
- Our demanding task can only be worked out efficiently by cooperation. Mutual cooperativeness is a benefit for every participant.
- Our many partners working together means we also support solution resolution for our partners own problems. Areas such as how to improve their waste management systems or the question of effective storage of residues without aftercare.
- Cooperation increases the efficiency and enables the focus to be on finding solutions.
- Transparency in communication is essential for the public and enables efficient solutions.
- Switzerland can claim leadership in the realization of a sustainable treatment of waste management and residues.
Benefit For The Waste Management
- Development Of Legal And Technical Standards
- The Swiss environment protection law from October 7th 1983 contains valuable guidelines for waste management that have to be followed by waste owners, the authorities (, i.e. the communities and the cantons,) and owners of incineration plants. In many aspects the federal council of Switzerland is empowered to issue detailed regulations which ore done following numerous legal ordinances.
- In an overall concept for waste management in Switzerland, published in 1986, the Swiss government stated different principles and goals. Since the implementation of these legal ordinances the Swiss policy of waste and resource management has already achieved credible results towards realizing these goals. However in important areas the ambitious aims are yet to be reached. This is especially true for the handling of residues from thermal waste treatment. Further technical solutions are required which – to some extent – still have to be developed and put into practice.
- In the process of the total revision of the Technical Ordinance on Waste (TVA) the conclusion was to focus more on the use of the state of the art practice in waste treatment. Instead of prescribing certain technologies “the best available solution at the time” is demanded. This dynamic formulation allows reacting more quickly to new developments and yet helps to reach the aspired goals faster and more efficiently.
- ZAR can yield important contributions to the development and maintenance of technical standards in Swiss Waste Management, primarily – but not exclusively - in questions of thermal treatment and recovery of solid residues.
