Regenerative Energie
The development of pyrolysis and gasification plants has shown that waste is a very difficult material to be treated. The basic problems are the heterogenic material with a lot of hazardous components which pollute the gas, the char, the oil and the waste water. Nevertheless waste components with a high calorific value and little contaminates is used in pyrolysis as well as gasification plants. The plasma technology has not proven to be a reliable option in waste management.
Waste gasification and pyrolyzation technologies are used to pursue similar benefits as are derived from waste incineration. Waste materials are significantly reduced in volume and are converted to a physical state that permits their storage without serious effects on the environment. The relationship between various thermal processes such as drying, pyrolysis, gasification, and incineration are presented in Table 1. During conventional incineration, the processes of drying, pyrolyzation, gasification and combustion (burning of gaseous products), take place in a combustion chamber. During pyrolysis, some of these incomplete processes are allowed to take place in separate reactors, which makes pyrolysis and gasification separate waste treatment processes. However, pyrolysis was unable to compete with incineration because of many problems and its insufficient availability. There is only one MSW pyrolysis facility in operation in Burgau, Bavaria, since 1984 and no additional pyrolysis facilities are planned.

Rechtliche und praktische Unsicherheiten bei der Durchführung des europäischen Klimaanpassungsrechts durch das Bundes- Klimaanpassungsgesetz (KAnG)

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.
