Regenerative Energie
The greenhouse (GHG) gas and energy performance of bio-waste treatment plants was investigated for characteristic bio-waste treatment concepts: composting, biological drying for the production of biomass fuel fractions, and anaerobic digestion. In contrast to other Life-Cycle Assessment (LCA) studies the focus was put on the direct comparison of the latest process concepts and state of the art emission control measures. In addition the value of compost as a soil improver was included in the evaluation.
The study is based on data from operational facilities which are combined with literature data. To ensure a direct comparability the same quantity of waste (25,000 t bio-waste and 5,000 t green waste input per year) and composition have been modeled for all concepts concerned. The results show that all concepts contribute to a reduction of GHG emissions and show a positive balance for CED. Compared to other studies the advantage of anaerobic digestion compared to composting is smaller as a result of accounting the soil improving properties of compost. Still anaerobic digestion is the environmentally superior solution, due to the high energy conversion efficiency of biogas to electricity and heat.

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.
