Organiser David Ingles says that 'the meeting strongly confirmed that there is a growth future for both polymer compostables and degradables in a rapidly expanding market.
Events such as these are vital for the progress of the sector'.
Ingles cautions however, that 'the lack of a coherent national waste strategy together with a lack of clarity on disposal routes is a significant barrier to the large scale adoption of any of the various existing technological solutions now waiting in the wings.

There is an opportunity for Government and the industry to get together and thoroughly technology road map the future of the sector'.
The May 5 meeting also noted that current compostable and degradable products seem limited to short-shelf-life products and that the long term aim should be sustainability before compostability/degradability.
The morning sessions were divided into compostable and degradable streams: the polymer degradable issues raised included.
* Recyclability of oxo-degradable materials with reference to supplemental stabiliser systems and effect on the (mixed) waste stream.
* Production of "traditional" polymers from renewable sources.
* The test methods contained within ISO 13432 are designed to simulate an industrial composting situation.
* The concept of land acting as a "Carbon sink" and the relative contributions of compostable vs degradable materials to biomass production.
* The draft for the new BS 8472 was discussed (currently at the comment stage).
Prof Scott believes there is a need for independent validation and verification.
Compostable issues raised included.
* Need for measure of compost quality such as PAS 100.
* Need for identification and labelling via logo and clarification of 13432 and applicability to home composting.
* Consumer awareness - all aspects of compostable packaging.
* The need for a rapid indicative test due to the lengthy/expensive tests that form 13432.
* Government involvement discussed - currently a lack of constructive dialogue (reference German and Dutch examples).
In addition, a sizeable portion of the day was allocated to networking and there was a combined group discussion during which the aim was to identify key issues and barriers to progress.
