Domestic waste is a complex particulate material, whose behaviour is difficult to characterise and quantify. Its particulate nature has led to the application of the principles of soil mechanics as a basis for quantifying its mechanical behaviour (Powrie et al., 1999). In general there will be three distinct phases present - solid, liquid and gas. Even in processed waste, different types of particles may be present, and are conventionally classified as follows (e.g. Landva & Clark, 1990; Grisolia et al. 1995).
Municipal solid waste is a heterogeneous material consisting of particles made of materials of various densities, many of which are crushable, deformable or biodegradable. Voids may be drainable or non-drainable and potentially filled with degradation gas, and some materials such as paper and textiles may be absorbent. As the waste is compressed, a structure may develop that result in preferential flow paths. As not all particles are solid, flow may take place within two networks corresponding to slow and rapid drainage, with not all of the voids taking part in either flow regime. All of this has major implications for the applicability of conventional mechanical and flow models in wastes. This paper explores the development of techniques for the non-invasive investigation of changes in the structure of milled MSW as it undergoes anaerobic biodegradation.

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.
