Regenerative Energie
In the present paper the different approaches which have been proposed so far for CO2 emission control from waste-to-energy processes will be reviewed. Both well-developed and innovative techniques will be presented, and a critical evaluation of the technical, economical and environmental aspects involved will be presented.
Along with waste production prevention, recycling and materials recovery, waste to energy is one of the options that should be put into operation for integrated waste management to be at the same time technically efficient, economically feasible and environmentally sustainable. For waste management to succeed, all the waste processing options must be interconnected and used in concert. Focusing on energy production from wastes, irrespective of the technology in mind (combustion, gasification, pyrolysis, ...), technical and scientific efforts must be devoted towards minimization of the potential environmental impacts related to both solid residues and gaseous emissions generated by the process. Thanks to the considerable improvements in the flue gas treatment processes achieved over the past decades, waste-to-energy technologies are currently considered to be highly reliable for control of the emissions of both macro- and micro-pollutants. Nevertheless, the greenhouse gases -and particularly the CO2- problem has recently become a critical issue in the framework of global warming, and it is expected to increase in the years to come if the progressively more stringent objectives of the Kyoto protocol are to be met. In this paper, CO2 capture and sequestration techniques will be reviewed and their potential applicability to waste-to-energy systems will be critically evaluated. At least three complementary options can be investigated in order to reduce CO2 emissions generated by waste-to-energy systems: improve energy conversion yields and promote energy savings; develop systems for CO2 removal from the flue gas; switch to innovative processes implying optimization of waste pretreatment and energy production from wastes. To be successful, the three approaches should be used in concert.

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.
