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.

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.
