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.

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.
