Endocrine disruption has become one of the most important environmental issues, causing scientific, political, legislative, and administrative action. Bisphenol A (BPA), octylphenol, and nonylphenol are three prominent representatives of xenobiotic estrogenic endocrine disrupting compounds (EDCs).
Since both BPA and alkylphenol polyethoxylates are used in paper production, and the contamination of recycled paper products with these compounds can be hypothesised. Concentrations of BPA and four alkylphenolic compounds in toilet paper, wastepaper, and cellulose have been investigated at the Department of Waste Management, Dresden University of Technology, Germany. Preliminary results and calculations are presented. With one exception, all xenoestrogens studied were found in all toilet paper samples at very high concentrations of 2 – 430 mg/kg dry mass (DM). The BPA concentrations in seven classes of wastepaper amounted to 0.093 to 4.23 mg/kg DM. In three types of cellulose the EDC concentrations were below or hardly above the respective limit of quantification. Toilet paper, thus, was shown to be an important source of xenoestrogen emissions to wastewater. Thermal paper again was found to be a major source for the contamination of recycled paper with BPA. Because of distinct contamination with xenoestrogens, paper waste and recycled paper products should not be mixed with biological waste e.g. for co-composting or co-fermentation in order to derive organic fertilisers.

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.
