Biplastics
1. Bi plastics are a family of different resin types, which
are either bio-based or compostable or both. Bi plastics add new properties and
performance characteristics to the huge family of plastics. So-called
oxo-biodegradable polymer products, which fragment into small pieces, are not
considered to be a bioplastic. 2. Bi plastics have been developed to address a range of
sustainability issues. The use of renewable raw materials instead of fossil
sources and where applicable, their biodegradability can also make a
difference. Like with every other (plastic) product, claims about
sustainability need an individual assessment and a differentiated approach. 3. Considerable investments have been made by the global Bi
plastics industry and high growth rates result from a continually increasing
market interest. This has continued even through the currently difficult
economic situation and is expected to continue.

graph 1) 4. The term “bioplastic”
today can also cover commodities like PE or PET which can be fully or partially
bio-based and perfectly recyclable – in exactly the same way as fossil-based PE
or PET. However the bio-based content can lead to an increased degree of
sustainability. 5. “Older” Bi plastics have been in the market place for decades
due to their excellent application performance, e.g. certain types of
polyamides and PUR or cellulosics – without causing any significant issues for
recyclers. 6. The recycling industry has found workable solutions to
handle a huge variety of post-industrial and post-consumer plastic waste. The
existing sorting and processing technology can handle Bi plastics either
without or with slight adaptation to specific material characteristics. 7. In reality Bi plastics represent a high growth business
opportunity rather than a threat to the plastic recycling industry. One example
is PLA, a polyester which can be recycled in a similar way to PET. Separation
technology allows high value recycling of both resin types. The establishment
of an infrastructure for the recycling of PLA has started recently. 8. Organic recycling of compostable polymers – e.g. in
composting plants – adds new efficient recovery options to the world of
plastics recycling and has significant advantages where heavy contamination
with food waste or soil is unavoidable, e.g. catering products, tableware,
mulching film, etc. Bi plastics are used for plastic molded parts, like injection blow
molding, injection molded products, vaccum molding. etc 9. Energetic recovery is a viable and useful solution until
volumes allow the operation of more sophisticated ‘back-to-plastics’ recycling
schemes. When renewable raw materials have been used for the production,
renewable energy can be recovered. 10. European Bi plastics calls on the traditional plastic
and recycling industries, industrial plastic users, NGOs and governmental
institutions to develop and establish workable solutions, in legislation as
well as in practice, which support the increase of plastics recycling and the
use of recyclates – whether from conventional, bio-based and/or biodegradable
plastics.
