Sustainability
“..meet the needs of the present without compromising the ability of future generations to meet their own needs.” Brundtland report 1987
Economic growth Linked to waste production (unsustainable)
Plastic Highly desired & highly problematic
Biodegradable plastic Compostable and high value uses
Integrating technologies The key to success
Sustainability and eco-innovation

Waste opportunity
Waste as a target– Increasing cost of waste management– Uncertainty about waste management in the future– Limited technologies for high value conversion– Low cost starting material
Petrochemical plastic wasteScientific academic challenge
Poor recycling ratesPS – 2% recycling rate in US (highest worldwide)PET- 25% recycling – collection system in operation PE – 10% recycling – Farm plastics – collection scheme

Bioplastic Opportunity
Biodegradable plastic – Premium product– Rapidly growing markets– Petrochemical US$ 300 billion market– Bioplastics 25% share of market by 2020
Polyhydroxyalkanoate (PHA)– Packaging, agriculture, textiles, medicine– Biocompatible (biomedical implants/wound healing)– Highly desired by industry– One of 5 chemicals to change the world (Forbes)

EU lead market Initiative and Kok Report The production of a single (bio)product from waste or renewable resources (Single (bio)refinery) is not sustainable (Life cycle analysis)
Sole product mentality obsoleteBiofuels – bioethanol, biodieselBioplastics – Polylactic acid, polyhydroxyalkanoateBiolubricants – plant oils
Need for integration of emerging technologiese.g. Biofuels and bioplastics
Technology integration: key to success
