Recycling, re-using and reducingAs April 22 is Earth Day, Paula Hammond's activities offer the chance to introduce children to the concept of materials and their propertiesPaula Hammond
Recycling of polymers from plastic packaging materials using the dissolution-reprecipitation technique Polym Bull 2009;63:449-465.D. S. Achilias, A. Giannoulis, and G. Z. Papageorgiou, "Recy- cling of polymers from plastic packaging materials using the dissolution-reprecipitation technique," ...
Yves Salomon took the opportunity to buy Hockley’s space when it was closing down and kept on the leather workshop, adding its makers to the team. So as a result we have a reinvigorated luxury workshop in the middle of town, able to do everything from create fur linings to repair old...
Shred and Mix: Shredding and mixing the collected materials down to the minimum. Dissolve, Filter and Polymerize: Melting down the shredded polyester and ridding them of previous dyes through a chemical recycling process. Melt, Spin, Knit and Sew: The melting allows the newly produced polymers to...
8.A method of dry cleaning of textile articles with a composite solvent having a plurality of components and of recycling the used composite solvent for reuse, said method comprising:a) a dry cleaning cycle comprising contacting fabric articles to be cleaned with the composite solvent,b) recoverin...
parallel band. This study succeeded in regenerating the tensile properties and inner structures in recycled PP, which could prolong the used lifetime and decrease the amount of waste from single-use plastic.

The recovery of platinum group metals (PGMs) from waste materials involves dissolving the waste in an aqueous solution. However, since PGMs are precious metals, their dissolution requires strong oxidizing agents such as chlorine gas and aqua regia. In this study, we aimed to recover PGMs via the...
aMaterials and Methods. This study analyzed the material flow re-sulting from the Law and other processing flows to quantify the global warming effect caused by home appliance recycling using the life cycle assessment (LCA) method. To evaluate the Law and to develop policy planning, the challeng...
The process used in RE:JERSEY means that old garments that feature logos, embroideries and club badges, which previously hindered recycling efforts to turn old garments into new ones, can now be used. The RE:JERSEY project takes footba...
This calls for a modification of the treatment scheme, e.g., by recycling the effluent of the precipitation unit to the WWTP together with the sediment from the re-dissolution unit. Additionally, the high pH of the final effluent may necessitate further treatment or adjustment to comply with ...
