Regenerative Energie
SUMMARY:
In North Rhine-Westphalia (Germany) about 235,000t DM of the sludge accrue from the ten water associations. The strategy of transport and sewage sludge disposal of the water associations is primarily cost-orientated. A reasonable cooperation between the different water associations does not take place.
To identify the optimisation potential in the first step an inventory of the different sewage sludge disposal options in North Rhine-Westphalia was carried out. In the second step the various sludge disposal options of the Ruhrverband and the Aggerverband were ecological evaluated. These two water associations were chosen for the ecological evaluation, because they use different strategies for sewage sludge disposal. The ecological evaluation revealed, that in many modules an essential part of the environmental burden is caused by the transport of the sewage sludge. Additionally the inventory of the sewage sludge disposal showed the high potential of minimization of the transport and thus reduce the environmental impact significantly. The transport minimization can be accomplished not only by the utilisation of free capacities at the treatment plant locations but also by the determination of pre-treatment plants which are located advantageously.

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.
