                        BUSINESS UPDATE AND BOARD CHANGE
                                  GRANT AWARD


                                BUSINESS UPDATE


Symphony Environmental Technologies Plc ('The Company,') the degradable plastic
and waste-to-energy Group is pleased to announce that since the last business
update on 22 February 2007 significant progress has been made in a number of key
business areas. In Portugal the country's largest retail group, Sonae, has
adopted d2wTM in all their carrier bags for their Continente, Mondelo and
Mondelo Bonjour supermarket chains, which are estimated to account for more than
500 million bags per year. This is significant not in terms of absolute value,
but for the breakthrough which it represents. This builds on the current
portfolio which includes Marriott, Royal Caribbean Cruise Lines, Tesco and the
Co-op who all presently use d2wTM finished products or our additive technology.


On 22 February 2007, the Company also announced delays in orders in a number of
key overseas markets. Following high level discussions with major clients in
these territories these problems have now been addressed and corrective action
taken to bring sales levels into line with management expectations. Further
updates will be made when the Company's Preliminary Results are announced before
the end of May.


The Company also announces that Matthew Turner, Group Managing Director, left
the Company on Friday 27th April following a review by the Company. There are no
plans to appoint another Group MD.


A strategic review of the organisation of the business is nearing completion.
There are now three operating subsidiaries (see notes to editors), and in future
the Plc itself will be organised into separate operating departments each headed
by a specialist reporting to the Chief Executive and thence to the Board. It is
anticipated that this will improve the efficiency and management control of the
Company and will focus specialist expertise where it is needed.



                        £50,000 GRANT FROM UK GOVERNMENT



Symphony Energy Resources Ltd. ('SER'), a wholly-owned subsidiary of Symphony
Environmental Technologies Plc, was created to focus on converting
waste-to-energy by innovative processes. It is currently working with two
waste-to-energy reprocessing technologies, Thermal and Microwave Pyrolysis. The
Company, is pleased to announce that SER has accepted an award from the UK
Secretary of State for Trade and Industry of a grant of £50,000 for a
feasibility study into microwave pyrolysis of scrap tyres.


SER will be undertaking this study, in association with Imperial College,
London, to gain a greater understanding of microwave activity in this
application, and of the thermodynamics of microwave degradation of tyres.


The outputs of microwave pyrolysis are a Tyre Derived Oil (TDO) and carbon
black.  Microwave energy is more efficient than heat in terms of
processing-power consumed and is expected to give off lower direct and indirect
emissions per ton processed.  The output products are expected to be cleaner and
therefore of higher value than their thermal equivalent. The study is due to
start shortly and is expected to run for a period of 20 weeks.


These technologies address two of the world's most significant environmental
concerns, - the disposal of waste, and the reduction of dependence on imported
oil. The Company will announce the findings of this study in due course.
