Regenerative Energie
To increase the recycling rate of paper and board, we investigate how yet unexploited paper and board from lightweight packaging waste can be recycled. Therefore, an environmental assessment via life cycle assessment (LCA) is crucial for the project to determine if the benefits from recycling exceed the efforts needed.
In existing LCAs, the recycling process has often been calculated generically. However, to adequately model newly developed recycling processes, a broad data basis is needed, which can be obtained by primary data collection or from the literature. To qualify the influence of data sources on LCA results, we built LCA models for recycling paper and board from lightweight packaging waste based on both primary data - measured during production trials - and secondary data from the literature. We showed that unlike the model based on data from the literature, the model based on primary data described the recycling process on plant scale more accurately as the literature provided averaged and sometimes outdated data. The differences in the environmental impact assessments were mainly due to the high sensitivity of the parameters for energy consumption and reject compositions. We also showed that the parameter uncertainty was mainly caused by database processes from the background system.

Rechtliche und praktische Unsicherheiten bei der Durchführung des europäischen Klimaanpassungsrechts durch das Bundes- Klimaanpassungsgesetz (KAnG)

In the context of the European Climate Law (EU) 2021/1119), the Governance Regulation (EU) 2018/1999 and the Nature Restoration Regulation (EU) 2024/1991, the KAnG came into force on July 1, 2024.
Transformatives Klimarecht: Raum, Zeit, Gesellschaft

This article contends that climate law should be conceived as inherently transformative in a double sense. The law not only guides the necessary transformation of economy and society, but is itself undergoing transformation.
