Viele moderne Technologien basieren auf dem Einsatz funktionaler Materialien, die aufgrund ihrer chemischen Zusammensetzung und ihrer Mikrostruktur für die jeweiligen Anwendungen spezielle makroskopische Eigenschaften aufweisen.
Life Cycle Inventory is one of the longest part of the LCA and yet we cannot always get all the necessary data. This study is a methodological point of view on getting a quality results from a case study of polypropylene recycling, based on an intersection of currently used methods of benchmarking the unavailable data, using the sensitivity analysi...
This study examines the effectiveness of displaying a persuasive message, feedback, and social comparative feedback on recycling behaviors in a cafeteria in a French university. Participants were students and university staff. On a daily basis, we measured two dependent variables: the weight of correctly recycled items and the number of sorting err...

A stable supply of alloy elements is essential for steel production, and strategic management of alloy elements is important not only for the steel industry, but for every manufacturing industry However, in the current recycling system, steel scrap is mainly used as a source of iron. When scrap contains large amounts of alloy elements, they were re...

AbstractPoly(methylhydrosiloxane) [PMHS, R(OSiMeH)nOR] is applied in chemistry as cheap, low-toxic, air and moisture stable reducing reagent. However, along with the desired products significant amounts of silicone waste is produced, since only ~1.7 % of the PMHS is employed for the reduction process. The formation of PMHS-waste reduces the sustain...
The objective of this work is to characterize the mechanical behavior of composites made with recycled polymeric matrices reinforced with natural fibers. The materials studied in this thesis are the polypropylene matrix and the coconut fibers for reinforcement. The morphological and mechanical characterization of these materials is undertaken with ...
At Tata Steel IJmuiden a part of the blast furnace dust is not recycled to prevent too high zinc levels in the blast furnace. Blast furnace dust is first separated from the off-gas into dry dust and sludge. The dry dust is collected in a dust bag and is directly transported to the sinyter plant. Then the sludge is separated by size through hydrocyc...

Poly(vinyl chloride) (PVC) in PVC-coated poly(ethylene terephthalate) (PET) fabrics can be separated through dissolution in a suitable solvent, leaving only the PET fibers. We investigated the solubility of PVC in 30 solvents using swelling tests. The results were compared with those obtained using the Hansen, Gutmann, Swain, ET(30), and Kamlet–Taf...

Improving effects of recycled polyethylene on dimensional stability, mechanical properties, and reduction in adhesive consumption of particleboard made from canola residues were studied here. Canola residues were consumed at 0, 30, and 50 % consumption levels, based on the dry weight of wood particles. Recycled low-density polyethylene was also con...

This work describes the leaching behavior of potentially hazardous metals from three different clay-based industrial ceramic products (wall bricks, roof tiles, and face bricks) containing foundry sand dust and Waelz slag as alternative raw materials. For each product, ten mixtures were defined by mixture design of experiments and the leaching of As...
