“Tell me how you segregate your waste?” – China and Germany exchanged experiences in low-carbon waste management during the IE EXPO 2019 in Shanghai

April 16, 2019

China IWM NAMA project jointly with CAUES and German RETech Partnership organized a two-day workshop on Municipal Waste Segregation and Low-Carbon Development on April 15-16. Held during the Shanghai IE EXPO 2019, the event attracted around 40 participants from German and Chinese research & academic institutes, associations, private companies as well as welcomed representatives of the five project demonstration municipalities.

On April 15, the event started with a guided tour to the booths of four companies focusing on waste segregation and biological waste treatment, namely, Purac – one of the leading companies in kitchen waste treatment, biogas production and oil recovery; Doppstadt, providing waste sorting equipment and technology; Eggersmann, specializing in mechanical-biological treatment and dry fermentation technologies; Tomra, offering state-of-the-art solutions for waste sorting and collection. The showcased solutions sparked in-depth discussions among the participants as well as brought new ideas to the demonstration municipalities on how to optimize their waste management systems.

On April 16, Qian Mingyu, the project director of IWM NAMA, opened the second day of the workshop by stressing the interconnections between Waste Segregation and Low-Carbon Development as well as emphasizing the role of policies and economic mechanisms in fostering the transition towards a sustainable and integrated waste sector.  Then, Prof. Michael Nelles from German RETech partnership and Prof. He Pingjing from the Institute of Waste Treatment and Reclamation, Tongji University, made presentations on policy frameworks, standards and implementation of waste segregation at a source in Germany and China respectively.

Dr. Joachim Clemens from the University of Bonn followed with an overview of methane emissions from landfills, showcasing results of his fieldwork in China and stating the importance of landfill operation optimization for achieving GHG emission reductions. Dr. Zhou Hongming from SinoCarbon systematically elaborated from which sources GHGs occur in the process of MSW management, how to quantify emissions and emission reductions as well as monitor the relevant data. As an example, Dr. Zhou Hongming referred to the calculation of potential GHG emission reductions in the demonstration municipalities of China IWM NAMA based on the data collected during the baseline study . After that, Kristian Wilkening, project director of a GIZ Project Capacity Building for Emissions Trading Schemes (ETS), brought in some insights regarding the opportunities that ETS might open for the waste sector in future. Last but not least, Nina Mitiaieva, Technical Advisor of the China IWM NAMA project, ended the session, offering an overview of the practical measures German cities undertake to promote and incentivize waste segregation at a source.

Overall, the workshop highlighted the strong interrelation between the different scales of MSW management and their implications for the level of GHG emissions – from the way the waste is handled by households to the subsequent treatment solutions and inclusion of the waste sector in ETS.
