To design a landfill several technical information of the soil are necessary. To get them geological, hydro geological, meteorological and geotechnical investigations must be done. In a landfill in construction projecting his evolution technical information also from the solid waste
are necessary. They are part of the body and must be treated and recognized as an important part of the whole mass. All the landfill is treated as a fill and geotechnical procedures are necessary in the analyses of his stability, deformation and lifetime. Among these parameters important is the specific weight. It is used in the stability analyses and in the life time prevision. The water content has a relationship with the biodegradation and consequently with the gas and leachate production. They are important for the determination of the gas and drainage systems in the landfill.
When designing sanitary landfills, it is difficult for the engineer to determine the geotechnical properties of municipal solid wastes. Thus, the objective of this paper is to present a new apparatus capable of obtaining directly fundamental properties of the geotechnical behaviour of material disposed of in landfills, such as: unit weight, water content, water capacity, medium unit weight of solid matter and porosity. All the equipment components were designed to collect waste samples in the field with minimal disturbance. The tests carried out in the laboratory, using these samples, were taken with the equipment’s own sampler. With the objective of checking the quality of the new equipment, several samples were measured in the field to determine the unit weights. This data was compared with the unit weights measured with the so called "trench method", carried out in the same places, in the landfills of the cities of Santo André and Paracambi. In addition, to broaden this confirmation, unit weight values determined by topographical survey in the sanitary landfill of Santo André were also used. The geotechnical parameters determined by the new equipment were beneficial to engineering projects, being a pioneer tool that is economic and leads to a better knowledge of solid waste disposed of in a landfill.

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.
