Regenerative Energie
Biochar has potential to improve soil fertility specially when it is applied together with organic fertilisers e.g. compost. Previous studies have shown better results when biochar is co-composted with organic waste or manure.
Biochar may improve compost quality thus reducing losse during the process and improving microbial activity. A batch composting study was performed to evaluate the effect of biochar on composting process and on final compost. Greenhouse gas emissions (CO2, N2O, CH4), which reflect microbial activity, and changes of key chemical properties were monitored. The experiment was conducted in seires of 220 l drum composters during two months. Input materials were fresh horse manure and fast pyrolysis biochar (produced from soft-wood at temperature 500 °C). Control (pure horse manure without biochar) was compared to horse manure with biochar (10% dry matter basis). Preliminary results show lower cumulative greenhouse gas emissions with biochar ad dition and we presume that compost with biochar has also higher fertilisation value.

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.
