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.

Die innerstaatliche Umsetzung des Pariser Klimaschutzübereinkommens
- ein Rechtsvergleich

Like all public international law treaties, the Paris Climate Accords rely on national law for their implementation. The success of the agreement therefore depends, to a large extent, on the stepstaken or not taken by national governments and legislators as well as on the instruments and mechanisms chosen for this task. Against this background, the present article compares different approaches to the implementation of the Paris Agreement, using court decisions as a means to assess their (legal) effectiveness.
