Recycling development

Cineinnati, Oh., 10th-12th May 1999, session 11-C ENERGY BALANCE STUDY OF A NEWLY DEVELOPED RECYCLING SYSTEM FOR WASTE PLASTICS... 

The multi-layer structure of cartons continues to be an environmental issue. However, much has been done to develop recyclable technology for drinks cartons. One output uses a chipboard-effect material of the type used to make furniture at the other end of the lifecycle is incineration with reclaimed heat. 

Last, but not least, the possibility of material reclamation through well-developed recycling processes (zinc reclaim, bloating, etc.). 

The above catalytic systems for the asymmetric hydrogenation of quinolines are mainly iridium catalysts. In 2008, Fan and coworkers developed recyclable phos phine free chiral cationic ruthenium catalyzed asymmetric hydrogenation of qui nolines [23]. They found that the phosphine free cationic Ru/TsDPEN catalyst exhibited unprecedented reactivity and high enantioselectivity in the hydrogenation of quinolines in neat ionic liquid. The results were very excellent and enantioselec... 

The lithium-polymer version of these batteries is another area where work is needed. Lithium-polymer batteries are being rapidly developed for portable consumer electronics applications and may be used in the future for EV/HEVs since the polymer design mitigates safety concerns regarding lithium metal in large cells. Some work to develop recycling processes is under way, but no details have been published and no process test data have been made available. Although many of the constituents are shared in common with the Li-ion battery system, the presence of a solid polymer... 

Cofactor Regeneration - About 70% of enzymes use nucleoside triphosphates, nlcotlnetmlde derivatives [NAD(P)(H)], or CoA as cofactors. These enzymes include many of those of greatest Interest In the synthesis of fine chemicals. Since these cofactors are too expensive to be used stoichiometrically, it has been necessary to develop recycling systems for them. The problem of recycling the nucleoside triphosphates... 

Of course, as we will see with recycled and bio-based polyamide blends [LOU 13], it is wise to associate them both. It is also necessary to develop recyclable bio-based materials [MUL 13] and develop the use of natural additives [AMB 11]. 

M developed recycling-compatible label materials to enhance the recyclability of durable goods, including computers and electronics, by permitting the label to remain in place when the equipment housing is recycled, without detracting from resin perfor-... 

In conclusion, rubber-based blends are promising materials that can be designed to fulfill the requirements necessary for various types of applications— from medical devices and biomedical applications, to packaging applications, military and aerospace applications, tire industry applications, and structural applications. The chapter also addresses a new trend in the field of rubber-based product development— recycling old parts into powders and incorporating them in different matrices. 

Even when the plastics are sorted there is a major challenge to develop recycling process which can produce a recyclate which has a value and a demand in the market place. The availability of markets which can bear the economic cost of the recyclate is the final hurdle in presenting the recyclate for re-use. 

The University of Nottingham has worked on developing recycling for thermoset materials, including glass and carbon-fiber reinforced materials. The Fraunhofer Institute in Teltow has also worked on thermoset recycfing. ... 

To tackle these technical challenges a series of companies and trade associations were set up across the globe to develop recycling methods for these materials. These groups are ERCOM Composite Recycling GmbH (Germany), VALOR (France), SMC Alliance (USA) and the FRP Forum (Japan).
