Closed Material Loops
Closed material loops, sometimes known as closed loop material cycles, are where a raw material used to produce a product, is collected at end of life (EoL) and recovered for reuse in the next generation of the
In this example, Lexmark inkjet cartridges are collected in Australia and the USA, and certain models are separated by predominant plastic type. The cartridges are then processed in CtL's patented production equipment and the plastic fraction is separated from other fractions including ink, foam, and metals.
The plastic fraction is then further refined, blended with virgin resin (plastic), and sent to the injection moulder for production of new inkjet cartridges. This program has been running very successfully since early 2009 and the project partners are now working on expanding the concept to include other plastic types from other products. We are proud to add that this project was awarded "finalist" in the 2009.
