Further information on the Symphony Environmental Technologies Group of companies:

SYMPHONY ENVIRONMENTAL TECHNOLOGIES PLC is a specialist in controlled-life plastic technology and products - a system that works by a process called oxo-biodegradation. The technology is branded d2w® and appears as a droplet logo on many thousands of tonnes of plastic packaging and other plastic products.

Symphony also owns the trademark d2p for an anti-microbial technology that can be used in most types of plastic products to help protect against infection. Symphony is also developing innovative and cost-effective waste-to-value technology to convert scrap tyres and other waste-streams into valuable products.

Symphony's d2w® technology turns plastic at the end of its service-life into a material with a completely different molecular structure. At that stage it is no longer a plastic and can be bioassimilated in the open environment in the same way as a leaf.

Symphony has a diverse and growing customer-base and has established itself successfully as an international business. Products made with d2w® plastic technology can now be found in more than 90 countries around the world and in many different product applications.
