The feasibility of producing compost for soil amendment in quarry reclamation projects, from locally available organic materiasl in the island of Milos and in Fokis, was investigated. Different mixes, adjusted according to material availability and required compost quality, were composted in lab-scale reactors of 40 l capacity (Colombus Instruments), with continuous monitoring of T, airflow, and O2 consumption and CO2 production as measures of microbial activity.
Mixtures from Milos included seaweed and paper, were N-deficient, necessitating N addition, showed a slow rate of composting and resulted in composts with high conductivity, and in some cases, phytotoxicity. Materials from Fokis included manure and green waste and were far less problematic, resulting to composts with N content of about 3.5 ppm, low conductivity, and GI value above 60% in about 6 weeks. The microbial activity during composting of the Fokis materials was fairly intense, with peak CO2 production rate at 50 ml/kg ds/hr. Transformations of inorganic nitrogen forms were typical for the examined materials and the type of the process in all trials. The stable isotopes ratios (ä13C and ä15N) were determined using IRMS and were shown useful in the investigation of the microbial interactions during the composting process, deserving further investigation.

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.
