Regenerative Energie
Society and legislation are focusing more and more on sustainability due to ecological and economic reasons. This means that materials in general have to be used in a more sustainable way and that waste has to be turned into a valuable resource again. Searching for sustainable approaches the resource efficiency has come into play.
Rec2TecPart (Recyclates to Technical Parts) is an innovative process design for a cradle-to-cradle material flow of technical thermoplastics. The Rec2TecPart process is separated in modules (procurement, input management, recipe, production, technical part and LCC/LCA) which simplifies the implementation later on. Beforehand a company analysis should provide weaknesses and strengths of the actual process, implementation of the needed and adapted modules leads to the Rec2TecPart process subsequently. Once implemented, the process upgrades plastic waste by compounding to fabricate tailor-made materials ('RecHQâ€) for technical components in high quality. A key issue for success was the focus on product properties instead of trying to reach the material properties of virgin material.
Compounding was done on an intermeshing, co-rotating twin screw extruder including melt filtration and pumping. Mechanical, rheological, thermal and optical properties of RecHQ were determined and compared. Furthermore, an environmental life cycle costing was conducted.
To prove the suitability for daily use for both post-industrial and post-consumer waste, three case studies were executed. They verified that components made of 100 % RecHQ save at least 25 % CO2 eq. and 20 % costs providing technical equal properties compared to virgin material.

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.
