Borehamwood, UK — Symphony Environmental Technologies Plc has published another report confirming that d2w oxo-biodegradable (controlled-life) plastics have no material effect on the recycling process or on the recycled plastic products. The report, by the Austrian Transfercenter für Kunststofftechnik (TCKT) on 27th of July, confirms that recyclate from oxo-biodegradable plastic can safely be used in the manufacture of thick cross-section plastic products intended for long term use outdoors. Such products would include plastic lumber, garden and municipal furniture, and signage posts.
This is the fourth study of recyclable oxo-biodegradable plastics, adding to the two studies done by Roediger Laboratories in South Africa in 2012 and 2013. TCKT had itself reported on 17th March 2016 that recyclate from oxo-biodegradable plastic can safely be used in the manufacture of plastic film products (see the reports under symphonyenvironmental.com). TCKT are the European industry specialists in application-oriented research and development in plastics engineering.
The purpose of oxo-biodegradable plastics is that they will biodegrade if they get into the open environment as litter, and will not lie or float around for decades. During their useful life they are just as strong as conventional plastics, and can be recycled if collected.
According to Symphony Environmental Technologies, the same cannot be said of hydro (sometimes called compostable or bio-based) plastics, because they cannot be recycled with conventional or oxo-biodegradable plastic without detriment to the resulting products, and they are tested to biodegrade in the special conditions found in an industrial composting unit – not in the open environment.
As well as being recyclable, d2w oxo-biodegradable plastics can be made in plastics factories with their existing machinery and workforce at little or no extra cost. d2w is said to be commercially available now.
