Innovative Municipal Solid Waste Management training on Maximum Yield Technology successfully conducted in Germany

The Nexus approach highlights the interdependencies between achieving water, energy and food security for human well- being, e. g. basic services and economic development, while ensuring ecologically sustainable use of globally essential resources.The three “supply securities” water, energy and food depend on ecosystems and on each other. The three resources land, water and energy are part of this ecosystem and must be used and protected in a balanced manner. A circular economy an alternative to a traditional linear economy (take, make, use, dispose) keeps resources in use as long as possible, extracts the maximum value from them whilst in use, then recovers and regenerates products and materials at the end of each service life.
Most cities in Asia face similar solid waste treatment problems, namely increasing amounts of waste, unsegregated waste, high organic and humidity waste content, and lack of high quality Refused Derived Fuel (RDF) to be used as a fossil fuel substitute. The practical workshop on Maximum Yield Technology (MYT) was therefore conducted in the framework of the GIZ “Integrated Resource Management in Asian Cities: The Urban Nexus” project to answer these challenges with a specific Mechanical Biological treatment technology applicable to the Asian Municipal Solid Waste (MSW) context.
The training was held at the Zweckverband Abfallbehandlung Kahlenberg (ZAK) MYT MSW treatment facility in Ringsheim, Germany from 11 to 14 September 2018. It focused on Waste-to-Energy within the concept of the Circular Economy, as well as suggested how the participating cities and countries could contribute to the goals set in the Paris Climate Agreement, the Nationally Determined Contributions (NDCs), the Sustainable Development Goals (SDGs), and the New Urban Agenda (NUA).
Sixteen participants from 3 countries – India, Thailand, and Vietnam – attended the training. The composition of the participant group ranged from high-level representation from the Indian national level to the state level, Metropolis level and city level.
On the first day of the training, the participants were welcomed by Mr. Georg Gibis, the CEO of ZAK and Mr. Hubert Wienands, the Managing Director of EUWelle. The training then focused on the history and structure of a ZAK treatment plant using the MYT technology modules, as well as a site visit to the treatment facilities. ZAK is a special purpose association formed in a legal communal cooperation between the counties of Emmendingen (EM) and Ortenaukreis (OG) – based in Ringsheim. It serves 583,000 residents who produce 100,000 tons of household waste per year. That household waste is delivered to ZAK by a private company. ZAK then treats the waste via recycling, maximum yield extraction of biogas, RDF, and minimum disposal. ZAK also has a business unit called MYT Business Unit GmbH, which provides knowhow transfer and advancement for MYT based projects.

The second day saw the continuation of the visits to ZAK treatment facilities, but in addition the participants were provided with an opportunity to visit the paper production plant, which uses the high-quality RDF produced by ZAK as an alternative fuel. The third day continued with site visits to other relevant facilities and companies, such as Holcim Cement Plant (using RDF as fuel), Wehrle (one of the technology providers to ZAK such as the Multi Zone Rector), and Reterra   (the organic waste treatment and biogas production company). The fourth and final day emphasised the rules and regulations which make ZAK and MYT a successful case study in Germany and how it could be applied in the Asian context.
Overall, the training was able to reduce the information deficit when it comes to the mechanical and biological waste treatment of mixed MSW, the recovery of valuable and recyclable material, and the production of high quality RDF (alternative fuel) and its application.
The participants had positive feedback on all parts of the workshop and said that the new perspectives and knowledge gained are of excellent value to their solid waste management and urban development work. Participants from all countries expressed their intention of applying the ZAK model and MYT technology.

The practical workshop on Maximum Yield Technology (MYT) was conducted in the framework of the GIZ “Integrated Resource Management in Asian Cities: The Urban Nexus” project financed by the German Federal Ministry of Economic Cooperation and Development (BMZ) and organised jointly with the Local Governments for Sustainability (ICLEI South Asia), ZAK (Zweckverband Abfallbehandlung Kahlenberg/Special Purpose Association Solid Waste Management Processing Kahlenberg) and EUWelle. 

The leading participants from 3 countries: India, Thailand, and Vietnam, comprised:
Indian national level:Mr. Vijai Kumar Chaurasia, Advisor, Central Public Health Environment Engineering Organisation, Ministry of Housing and Urban Affairs, Government of India and Mr. Sanjay Kumar Singh, Director of NITI Aayog
State level: Mr. Ibrahim Adoor Balakila, Managing Director of Karnataka Urban Infrastructure Development and Finance Corporation (KUIDFC)
Metropolis level: Ms. Panitnart Tanaapinan of the Bangkok Metropolitan Administration
City level: Mr. Netiwit Roengsukpipatthana, Director of Sanitation Engineering Department  of the City Administration of Nakhon Ratchasima, Thailand and Mr. Pham Thanh Phuc, Deputy Director of the Environment Protection Agency (EPA) Danang, Vietnam
