Supports recyclable

The use of solid supported, recyclable catalysts, is a well-assessed technique in classic organic chemistry, and many exhaustive reviews dealing with this subject are available [105, 115]. The use of solid supported catalysts for library synthesis in solution has also been reported. Among others, Kobayashi et al. presented the use of a new supported scandium catalyst for 3CC reactions leading to solution libraries of amino ketones, esters, and nitriles (24-member model discrete library) [116], or to quinolines (15-member model discrete library) [117], and Jang [118] presented a polymer bound Pd-catalyzed Suzuki coupling of organoboron compounds with halides and triflates. This area was also briefly reviewed recently [119].

The Environment and Plastics Industry Council (EPIC) of Mississauga, ON, and Corporations Supporting Recycling commissioned a study of plastic sorting technologies in 2002. An update to the original study was released in 2005. It reported that the main manufacturers of mass-feed plastic bottle sorting equipment for the North American market... 

The use of PEG-400 [119], l2inEtOH and water (1 1) [120] or solid-supported recyclable catalyst like sulfated titania [121], MgBr2.0Et2 [122] and PEG-4500 [123] under microwave irradiation affords the Qxs in high yields and in a short reaction time (Scheme 2.21). 

There are now several standards in place that support recycled content claims, developed by third-party certification bodies (e.g., INTERTEK). Some companies provide their own guarantees, while others do not provide any validation and should be treated with care. 

So the order of magnitude of the costs is clear and supports recycling as being about equal to the cost of using a DGR for disposal if the future includes about 10 times more reactors. But there are also some other technical advantages and economic business opportunities for mining nations and the fuel (waste) owners, as well as massive social benefits.
