Interim results date - Analyst presentation

New d2p antimicrobial technology agreement

The Board of Symphony Environmental Technologies plc ("Symphony", "Group" or the "Company"), the AIM quoted specialist in environmental technologies, is pleased to announce that the Company's Interim Results will be released on Monday, 6 September 2010.

The Group has previously announced the launch of d2p antimicrobial technology for inclusion in the plastic product manufacturing process. The Company is pleased to announce that it has signed an agreement to develop and sell a new type of antimicrobial additive under the Group's d2p trademark. The Company believes that this additive could generate many potential benefits, including cheaper manufacturing costs without materially affecting a finished product's performance or the recycling process.

The agreement is structured so that payments are made only after the product is proved to be effective, non-harmful, commercially viable and patentable by the Company.

Michael Laurier, CEO of Symphony, said, "We are always looking for innovative ways to solve environmental problems with an eye to cost and value for the end user. We believe that this new agreement could enable d2p to become a key revenue earner and significant contributor to the overall Symphony business. This is an important step for Symphony in further developing an antimicrobial additive range and I look forward to updating shareholders when our tests are completed later this year."

The Company will be hosting an analyst presentation on the morning of the Interim results announcement at 9.30 am on 6 September 2010 at the offices of Bishopsgate Communications, 3rd Floor, 3 London Wall Buildings, London, EC2M 5PD.

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'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. Symphony is a member of the Oxo-biodegradable Plastics Association (www.biodeg.org), the Society for the Chemical Industry (UK), and the American Standards Organisation (ASTM). Symphony is also a member of the European Organisation for Packaging & the Environment (Europen), the US Save the Plastic Bag Coalition, and the British Brands Group. Symphony actively participates in the work of the British Standards Institute (BSI),the European Standards Organisation (CEN), and the International Standards Organisation (ISO)

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