In the UK, producer responsibility was enacted through a scheme for generating and trading packaging recovery notes, plus more recently a landfill levy to fund a range of waste reduction activities. These systems are likely to significantly improve the ability to separate complex mixtures as they can perform up to 860 000 spectra s1 and can scan each individual flake. However, biodegradable plastics also have the potential to complicate waste management when introduced without appropriate technical attributes, handling systems and consumer education. In addition, labels and adhesive materials should be selected to maximize recycling performance. Optical sorters can be used to differentiate between clear, light blue, dark blue, green and other coloured PET containers. They have the advantage that they can be used to sort different plastics that are blacka problem with traditional automatic systems. In Plastics and the environment (ed. Rev. 47, 277293.

Advances in technologies and systems for the collection, sorting and reprocessing of recyclable plastics are creating new opportunities for recycling, and with the combined actions of the public, industry and governments it may be possible to divert the majority of plastic waste from landfills to recycling over the next decades. If recycled plastics are used to produce goods that would otherwise have been made from new (virgin) polymer, this will directly reduce oil usage and emissions of greenhouse gases associated with the production of the virgin polymer (less the emissions owing to the recycling activities themselves). An average net reduction of 1.45 tonnes of CO2-e per tonne of recycled plastic has been estimated as a useful guideline to policy (ACRR 2004), one basis for this value appears to have been a German life-cycle analysis (LCA) study (Patel et al. For example, PVC and halogenated additives are typically present in mixed plastic waste leading to the risk of dioxins, other polychlorinated biphenyls and furans being released into the environment (Gilpin et al.
