New support in the STRAMENTO project

We are pleased to welcome a new student assistant at the department. Johanna Wiechen will support the research and development project STRAMENTO. The aim of "Stramento" ( lat. made of  straw) is to achieve an integrated energy and nutrient use of lignocellulose-rich agricultural residues through an innovative biogas process. We thus aim to sustainably reduce greenhouse gas and nutrient emissions as well as improve soil functions in addition to providing biogas and fermentation residue substrates.

Same or not - Sampling electrical devices with a focus on scavenged components


Even and especially in times of COVID19 people have cleaned up their basements and drawers, discarding defective or obsolete electrical devices (waste electrical and electronic equipment – WEEE). In the ARTII module students dealt with questions such as, “What kind of devices were thrown away?” and “Did they arrive at the waste collection in the same condition they were disposed of or have valuable components been scavenged?” With the active support of the CERT staff the students assorted a WEEE container over the course of two days. The results of this action are directly applied into research and are assessed by the students in a scientific paper.


CERT teaching team prepares for the new challenges of WS 2020-21!


For the first time in almost 6 months the complete teaching team met in person (following the standard distance and hygiene regulations) for a full-day internal teaching workshop to exchange our experiences from the summer semester 2020 and to outline the upcoming winter semester 2020-21.

Adopting to full online teaching in the summer semester 2020 was a big challenge, not only because of the short time to prepare, but also because of limited experience with the different software systems and media for online teaching .

During the teaching workshop we shared our experiences, discussed the evaluations, and gave some feedback and didactical input to identify possibilities and opportunities for improvement. In addition, we also started planning the modules for the next semester, especially Einführung in die Abfallwirtschaft, Waste-to-Energy and Advanced Recycling Technologies.

The CERT teaching team is highly motivated and looking forward to a new and better experience in the second predominantly online semester. Further information on the upcoming semester will follow. If you have any questions, please do not hesitate to contact the contact persons for the modules or .

Kick-off STRAMENTO Project

The aim of "Stramento" ( lat. made from straw) is to achieve an integrated energy and nutrient use of lignocellulose-rich agricultural residues through an innovative biogas process. We thus aim to sustainably reduce greenhouse gas and nutrient emissions as well as improve soil functions in addition to providing biogas and fermentation residue substrates. We carry out this project in close cooperation with our partners, the Herbst Umwelttechnik GmbH.

The project, funded by the Federal Ministry of Economics and Energy, will start in February 2020, and is scheduled to run for three years.

All new information about the project will be announced here in the newsfeed or on the Stramento blog.

We are always happy to have students working with us on the project. If you are interested in writing your thesis within the Stramento project, please contact .

Fruit Logistica


On February 7th the CERT tutors and other highly motivated helpers participated in the Fruit Logistica, the collection campaign of the Berlin food bank, Berliner Tafel e.V. Thanks to the event and with the support of the THW, the voluntary fire department and the Red Cross, more than 85 tons of food could be saved by 350 volunteers. Easily perishable fruit was processed into jam the very next day and is now being delivered to various food banks in the city, along with the remaining food. The Berlin food bank has been organizing this event at the Fruit Logistica Fair for many years in order to reduce the wasting of food and to support people in need.

It was an exciting evening for us tutors and we hope to be there again next year!

Prof. Vera Susanne Rotter holds speech on traffic reform at the Berlin Recycling and Resource Conference 2019

Climate protection and circular economy are both areas of environmental protection policy that have been operating independently without being coordinated with each other. However, with the implementation of the energy and traffic reform resources that were previously often not used in mass quantities are needed. For the present we need to primarily find ways to produce these resources in an environmentally and socially just manner, and the hereby occurring used products need to be recycled to a high standard in the future. The introduction of electromobility offers the opportunity to set the right course. This is why the German Advisory Council on the Environment (SRU), in which Prof. Rotter, as a member of the Council, represents issues concerning resources as well as circular economy, has not only developed suggestions for climate protection in the traffic sector, but also addressed issues about resourcing and recycling aspects. The presentation of the report at the Berlin Recycling and Resource Conference will help to combine the areas of climate protection and the circular economy.

Poster presentation project week process engineering science (PIW)

The chair of circular economy and recycling technology, was represented with tow project groups at the faculty-wide project week Process Engineering Sciences. During the project week, two groups with a total of 17 first-semester students worked on topics about littering and bulky waste collection in the Berlin city area as well as the use and perspective of disposable single use plastic articles on the main campus of the technical university.
The random sampling of ten different Berliner districts led to the conclusion that the current collection system covers only an insufficient part of the bulky waste potential. Reasons for this appear to be high service barriers, such as poor accessibility and high fees, compared to bulky waste collection in other municipalities.
The researches at the main campus of the TU Berlin show that there are with the beginning of the new year 2019 already some initiatives to avoid single use plastic articles like cups, bowls, lids, cutlery or stirring sticks. The bioplastics PLA is often used as a substitution. But some of the establishments could raise more awareness regarding the utilization of such articles. Furthermore students have to be more sensitized.

ProSUM: Interview at Deutschlandfunk Nova

Approximately 440 t of Gold are on Europe's streets at the moment. At the end of life this valuable material ends up in shredder facilities. Researchers of the ProSUM project created the first Urban Mine Data Knowledge Platform to inform about arisings, stocks and wastes of secondary raw materials from vehicles, electronic equipment, batteries, and mining waste. Kristine Sperlich was working on the project and was interviewed by Deutschlandfunk Nova about the gold in our cars and makes recommendations for the Federal Government.

SRU Special report

On 23.11.2017, the German Advisory Council on the Environment (SRU) presented its special report "Time to take a turn: climate action in the transport sector". Currently, the transport sector is responsible for about one fifth of Germany's greenhouse gas emissions. While other sectors have seen significant emission reductions since 1990, emissions from transport have even increased slightly over the same period. In addition to demonstrating a strategic turnaround for transport, the SRU investigated the impact of restructuring the transport sector on the raw material demand and proposes a set of measures that addresses both the extraction of the necessary primary raw materials and the recycling of the raw materials used.
Prof. Vera Susanne Rotter – chair of the department Circular Economy and Recycling Technology - is a member of the German Advisory Council on the Environment in the Council period 2016-2020.
