Conference Biowaste 2021

International RETech-Conference
“Climate and resource protection through environmentally compatible collection and recycling of biogenic waste”

4. to 5. November 2021
Participation is possible on the conference itself in Berlin and online

The 4th international RETech Conference will take place on 4 and 5 of November, on this occasion on the subject “Climate and resource protection through environmentally compatible collection and recycling of biogenic waste”. You can participate on the conference itself in Berlin and online. The event venue is the Scandic Hotel at Potsdamer Platz.

The Conference is organized by German RETech Partnership in coordination with the German Biomass Research Centre (DBFZ), the University of Rostock and the German Agency for International Corporation (GIZ). The conference is funded by the export initiative from the Federal Ministry for the Environment, Nature Conservation and Nuclear Safety (BMU).

Further information regarding the program and registration will be found on this website soon.


Worldwide approximately 90% of the waste is still landfilled without any treatment, in which the components of organic waste amounts 50% to 70% the biggest percentage, and causes the most environmental problems. The sustainable recycling of biowaste and waste materials are part of the current topics of waste management besides plastic recycling and product responsibility, particularly in emerging and developing countries.

An environmentally friendly recycling- and waste management contributes significantly to the climate and resource protection. An example the landfills are worldwide the third largest emitter of the greenhouse gas methane and other climate-relevant gases. These gases are generated through the degradation of organic substance in the deposit under exclusion of air.


The purpose of the conference about the subject “Climate and resource protection through environmentally compatible collection and recycling of biogenic waste” is the exchange of experiences and knowledge transfer about promising approaches of the sensible recycling of material and energy applications, as well as the reduction of the volume of untreated biodegradable waste; more specifically untreated residential waste with a high biogenic percentage. As in previous conferences the focus will be placed on international networking of key stakeholders, as well as the support of the “New Green Deal” as roadmap for a sustainable EU-Economy. Practical experiences from Germany regarding the development and operation of approved technologies for the treatment and recycling of biogenic waste from different sources will be presented and possibilities for the know-how transfer and adaptation in different world regions will be discussed.

The exchange in form of expert contributions and discussions contributes to an integrated understanding of the subject, as well as to the challenges, and helps developing new strategies. As major reason for insufficient waste management in many countries-as an additional focus lies on the lack or not adequate financing; the role of policies and legislations and the responsibility of the municipality, or rather the responsible public institutions for waste management. The financing of fees, taxes, duties and government subsidies as condition of establishing a sustainable and self-sustaining waste management system, could not been established or only insufficiently. Tax systems as in Germany are often not transferable to other countries.

Speakers from relevant regions will be invited and report about existing frameworks, challenges and best practice approaches dealing with biowaste and the associated impact of climate and resource protection.
