Global Framework on Chemicals: Work on the German contribution

April 8, 2025

For a few weeks now, BZL GmbH has been working as part of a consortium on a project that will promote sustainable chemistry as part of the global transformation in line with the UN 2030 Agenda. The “Roadmap to 2030” research project (commissioned by the Federal Environment Agency, FKZ: 3724 65 701 0) aims to identify and prepare Germany’s potential contributions to the implementation of the GFC. The plan is to present the results at the first GFC conference at the end of 2026. At this conference, each country is to demonstrate how it intends to make the handling of chemicals safer and more sustainable.

Three priorities for the German contribution to the GFC

In coordination with the client, we will work with stakeholders from the chemical industry, recycling companies, consumer and environmental organizations to try to reach a consensus that is as broadly supported as possible. It is about

the “defossilization of the chemical industry”, focusing on the opportunities and obstacles for the German chemical industry to switch from fossil to renewable carbon sources,
a methodological framework to put alternative assessments for substance substitution towards “inherently safe chemicals” on a scientifically broadly accepted basis,
the use of the Digital Product Passport as an information medium for additives in plastics with a special focus on additives for recyclates, i.e. plastics from the recycling of waste.

We are pleased that we are tackling this task together with colleagues who have already been involved in the development of suitable indicators for SAICM and the successor organization GFC: the Center for Sustainable Consumption and Production (CSCP), N³ Nachhaltigkeitsberatung Dr. Friege & Partner and the Akademie Dr. Obladen.

We will contact numerous experts and also provide information here about specialist conferences that are planned as part of the project. Further information on the project can be found in this this information sheet.

Third-generation biodegradable plastics – A complementary strategy to tackle the marine litter problem (2025)

The amount of plastic produced worldwide has reached 400 million metric tonnes in 2022. Estimated 3–5% of this amount ends up in the environment, where it poses significant threats to ecosystems and biodiversity. Littering, a growing global challenge, requires a combination approach to tackle its causes and mitigate its impact. There are different strategies to combat littering. But even with immediate and concerted action to reduce consumption of plastics, more than 700 million tonnes of plastic waste will cumulatively enter the aquatic and terrestrial ecosystems until 2040. Waste management systems, even if improved, do not have sufficient capacity at the global level to cope with the huge mass of plastics entering the environment. Especially for plastic, which will foreseeable and inevitably enter the environment, where it can persist for hundreds of years (‘forever’ plastics), a solution is needed. Biodegradable plastics, that meet the criteria of ‘Safe and Sustainable by Design’ (SSbD) offer innovation perspectives and can be a complementary strategy to tackle the marine litter problem.

DGAW-Podcast Episode 41 – Hazardous substances in recyclates (in German)

October 2, 2024

New plastics consist of increasingly complex additive formulations and polymers. Can the recycling of mixed packaging plastics make new products safe at all or is the use of recyclates in consumer-related products even dangerous? In this episode of the DGAW podcast, Dr. Ines Oehme from the Federal Environment Agency and Prof. Dr. Uwe Lahl discuss this topic, moderated by Marvin Müller from Studio Grüner Ton. To the Podcast:

Sustainable Chemistry: Indicators for the Global Framework on Chemicals (GFC) on Track

October 1, 2024

At the United Nations World Summit on Sustainable Development in Johannesburg in 2002, it was agreed to minimize the adverse effects of chemicals on humans and the environment by 2020. To implement this so-called ‘2020 target’, the ‘Strategic Approach to International Chemicals Management’ (SAICM) was established in 2006. As the mandate for SAICM ended in 2020, work on a successor framework began already in 2015. Due to the COVID pandemic, among other things, negotiations on the specific design were protracted. Finally, at the end of the 5th International Conference on Chemicals (ICCM5) on 30 September 2023 in Bonn under the German presidency, the ‘Global Framework on Chemicals’ (GFC) was adopted with the’ Bonn Declaration for a Planet Free of Harm from Chemicals and Waste’.

The GFC was also given the mandate to develop indicators for the goals and targets adopted by the conference. This task is now being tackled. The GFC can also draw on the results of our project on indicators for future global chemicals and waste management, which was commissioned by the Federal Environment Agency. In brief: The indicators combine the concept of sustainable chemistry with the requirements of sound management of chemicals and waste. A list of the 23 most important indicators from this project was recently submitted to the GFC by the German representative in the responsible working group, Dr. Christopher Blum (Federal Environment Agency). We are pleased that the indicators developed in this project now serve as a basis for the responsible GFC working group (Open-Ended Ad Hoc Group on Measurability and Indicators). We want to continue to support this important approach of the GFC and are therefore planning a scientific publication in which the indicators developed in the project will be presented in the context of the global chemical policy debate.

Material Recycling of Plastics—A Challenge for Sustainability (2024)

The complexity of plastic polymers and even more so of additives has increased enormously in recent years. This makes the material recycling of plastic waste considerably more difficult, especially in the case of mixed plastic waste. Some additives have now been strictly regulated or even completely banned for good reasons (‘legacy additives’). Material or mechanical recycling generally uses old plastics that still contain these substances. Consequently, products that are manufactured using such recyclates are contaminated with these harmful substances. This poses a major challenge for sustainability, as there is a conflict of objectives between protecting the health of consumers, especially vulnerable groups, conserving resources and recycling, keeping material cycles ‘clean’ and destroying pollutants, and transporting them to a safe final sink. With regard to the first objective, we recommend avoiding the use of contaminated recyclates for products with intensive contact with consumers (‘contact-sensitive products’) until further notice.

In our recent article “Material Recycling of Plastics—A Challenge for Sustainability” we also show that the climate policy challenges for the plastics (and chemical) industry necessitate defossilization (‘feedstock change’). This turnaround can only succeed if solely closed-loop recycling takes place in the future; recyclates should primarily replace virgin plastics. For material or mechanical recycling, this means that this can only work if used plastics with a high degree of homogeneity and known formulation are collected separately, as is already the case today with PET bottles. The objective of this article is to illustrate the increasing complexity of plastic polymers and additives, especially legacy additives, which will force a legislative readjustment of todays’ material recycling.

Kunststoffe in der Abfallwirtschaft – closing the loop?

The circular economy will be an important, if not the decisive source of raw materials for the European economy after 2030. This applies not only to the supply of metals, but also to non-fossil carbon. What about the fossil carbon in the stock (plastics)? Only if it is recycled will it not have a climate impact. However, there is currently no reliable data available on the substitution of virgin plastics with recyclates (closed loop recycling) for the relevant plastic application areas (packaging, construction products, waste electrical and electronic equipment, vehicles). In our opinion, the feedstock change (“defossilisation”) in the plastics and chemical industry that is necessary from a climate policy perspective can only succeed if physical and chemical recycling is focussed on substituting “virgin plastic” in the future. The additives contained in long-lasting plastic products pose a problem here. Many of these substances are now banned or strictly regulated (legacy additives). The additives are usually recycled together with the material during mechanical recycling. The data on the contamination of recyclates from used plastics with hazardous or banned substances is a cause for concern. Based on the data available and its toxicological assessment, we recommend a moratorium on the use of recyclates for products with a high “user proximity” (contact-sensitive products like food packaging, kitchen utensils, toys, textiles, indoor products). Recyclates from closed, monitored product cycles should not be subject to this moratorium.

“Plastics Recycling and Hazardous Substances – Risk Cycle” available on preprints.org

July 2, 2024 The complexity of plastic polymers and even more so of additives has increased enormously in recent years. This makes the high-quality recycling of mixed plastic waste considerably more difficult. Some additives have now been strictly regulated or even completely banned for good reasons (“legacy additives”). Used plastics that still contain these substances are generally used for material or mechanical recycling. Consequently, products made from such recyclates are contaminated with these harmful substances. We therefore recommend, as already explained in our article in the journal Müll und Abfall “Kunststoffrecycling und gefährliche Stoffe – Risk Cycle”, avoiding the use of these recyclates for products with intensive contact with consumers until further notice. In our current article “Plastics Recycling and Hazardous Substances – Risk Cycle”, we also show that the climate policy challenges for the plastics (and chemical) industry necessitate a defossilisation (‘feedstock change’). This turnaround can only succeed if solely high-quality recycling takes place in future; recyclates should primarily replace virgin plastics. This can only work if used plastics with a high degree of homogeneity and known formulation are collected separately, as is already the case today with PET bottles. In this context, we would also like to point out inconsistencies in the current legislation on the European emissions trading system. The article by Prof. Dr. habil. Uwe Lahl and Dr. Barbara Zeschmar-Lahl is currently under review and can be viewed and commented on at preprints.org.
