Regenerative Energie
Worldwide many sites are presently influenced by mining and processing activities. The huge amounts of moved and treated materials have led to considerable flows of wastes and emissions. Alongside the many advantages of processed ores to our society, adverse effects in nature and risks for the environment and human health are observed.
In the EU-project (GREENLAND, Gentle Remediation of trace element contaminated land,FP7-KBBE-266124) 'best-practice†examples for remediation and re-use of heavy metal contaminated sites are brought together in an exchange of experiences. This exchange and collaboration will contribute to a final handbook which intends to form a basis and guideline for the remediation of such sites. Three stages of impact of Pb/Zn-ore-treatment on the environment are discussed here:(1) On sites where the ores are mined impacts are the result of crushing, grinding, concentrating activities, and where additionally parts of the installations remain after abandoning the mine, aswell as by the massive amounts of remaining deposits or wastes (mine tailings).(2) On sites where smelting and processing takes place, depending on the process (Welz, Doerschel)different waste materials are deposited. The Welz process waste generally contains less Cd and Pb than the Doerschel process waste which additionally shows higher water- extractable metals.

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.
