                                Business Update

                             Product Clarification







Symphony Environmental Technologies Plc ('Symphony' or 'the Company'), the
degradable plastics and waste-to-energy Group, is pleased to announce the
following:



BUSINESS UPDATE



The Group continues to make progress notwithstanding the delays affecting
performance which have already been announced.  In the oxo-biodegradable
plastics Division the transition from low-margin finished product to
higher-margin additive is taking effect.  In the waste-to energy Division we are
pleased to announce progress with Thermal Pyrolysis (see below) in addition to
the progress with Microwave Pyrolysis announced on 30th April.



Oxo-biodegradable Plastic (d2w)



The changes referred to in the Company's Business Update announcement on 30
April 2007 have started to have a positive effect on the business. Sales of
higher-margin products are growing and operating costs are falling.



The Company's announcements of 22 February and 30 April 2007 referred to delays
in a number of overseas markets, and that corrective action had been taken. Two
market areas were involved, and in the first we are pleased to say the issues
have been resolved. Most of the local stock has been sold and paid for, and new
orders have been confirmed for delivery. In the second market area, local stocks
are being sold, the process of reconfirming orders and stock repositioning is
ongoing, and further updates will be given at the Preliminary Results stage,
which will now be in June, rather than at the end of May.



Waste to Energy (Thermal Pyrolysis)



Symphony is also pleased to announce that Cabinet approval has been given in Sri
Lanka for an MOU between Symphony Energy Resources Ltd. (SER) and  the Ceylon
Petroleum Corporation (CPC) of Sri Lanka, supported by The Ministry of Petroleum
of Sri Lanka.



The project is to build a Thermal Pyrolysis plant in Sri Lanka in 2008 and has
been agreed as a result of meetings between SER and a team of experts from CPC.
It must be stressed that no contract has yet been signed, but the MOU represents
a major step forward for Symphony.



CPC is the state owned Oil Company of Sri Lanka and is the sole importer and
refiner of oil products into Sri Lanka.  Current operations include a refinery
in Colombo, over 800 filling stations throughout the island, supplies to the
marine bunkering companies, aviation fuel to the international airport, and
supplies of oil products to the independent oil companies.







Thermal Pyrolysis is a process that applies heat to plastics in the absence of
oxygen to break the chemical bonds. The system converts waste plastics into
Marine Diesel Oil (MDO), and is designed to recycle mixed plastic waste streams
into valuable and easily marketable products. The process provides an
alternative to conventional and more costly recycling systems and can use most
types of plastic waste that currently go to landfill. The system itself uses
very little energy and is self-sustaining with virtually zero waste from the
process. If the plant is constructed, in due course MDO output per unit is
expected to be in the region of 18,000 tonnes per annum or the equivalent of
150,000 barrels of oil.



This technology addresses two of the most pressing environmental questions faced
by governments worldwide - What to do with waste plastics, and how to reduce
dependence on imported oil.





PRODUCT CLARIFICATION (oxo-biodegradable plastic)



Plastics, recycling, compostability and renewable issues are now constantly in
the media and much confusion exists over this subject. Symphony's d2w(R)
oxo-biodegradable technology produces plastic which degrades by a process of
OXO-degradation, initiated by an additive.  The process involves  little or no
additional cost, as products can be made with the same machinery and workforce
as conventional plastic products. During their useful life they are just as
thin, strong, and durable as ordinary plastic.



It is important to note that the plastic does not just fragment. It is consumed
by bacteria after the additive has reduced the molecular weight, and it is
therefore 'biodegradable.'  This process continues until the material has
biodegraded to nothing more than CO2, water, and humus, and it does not leave
fragments of petro-polymers in the soil.



Eco-toxicity tests demonstrate that oxo-biodegradable plastic produces no
immediate, or cumulative, adverse effects on the soil, whether from the material
itself or from pro-degradants, plasticisers, surfactants, pigments, metal salts
or lubricants. D2w(R) does not contain 'heavy metals.'



The UK Food Standards Agency's Expert Group on Vitamins and Minerals has carried
out a risk assessment on trace elements and has shown that most of the metal
salts used in oxo-biodegradable plastics are trace-elements necessary for
healthy plant and human growth.



Unlike PVC, the polymers from which oxo-biodegradable plastics are made do not
contain organo-chlorine.  Nor do they contain PCBs, nor do they emit methane or
nitrous oxide, even under anaerobic conditions.



The time taken for d2w(R) products to degrade can be 'programmed' at the time of
manufacture and can be a few months or a few years. Exposure to sunlight
accelerates degradation, but the process of oxo-bio-degradation, once initiated,
continues even in the absence of light, so long as air is present.  Products can
be vacuum-packed for delivery and will not degrade in the absence of air until
needed for use.



On 24th May this year the Periodical Publishers Association of the UK
recommended to all its members that oxo-biodegradable film be used for wrapping
their magazines for distribution.  D2w(R) is already in use for this purpose.







Oxo-biodegradable plastics are currently made from a by-product of oil refining,
and oil is of course a finite resource, but this by-product arises because the
world needs fuels for engines, and would arise whether or not the by-product
were used to make plastic goods.



Unless the oil is left under the ground, carbon dioxide will inevitably be
released, but until other fuels and lubricants have been developed for engines,
it makes good environmental sense to use the by-product, instead of wasting it
by 'flare-off' at the refinery and using scarce agricultural resources to make
plastics.



D2w(R) has been certified safe for long-term contact with any food type at
temperatures up to 40degreesC, and oxo-biodegradable products are being supplied
by the UK's leading supermarkets, Tesco and the Co-op.  NB:  In view of the
major custom of Walmart, is there any prospect of tying up ASDA at some point?



In Portugal the country's largest retail group, Sonae, has adopted d2w(R)
plastic carrier bags, and other major users include Marriott, Royal Caribbean
Cruise Lines, BUPA, News International, Pizza Hut, KFC, and Walmart.
Oxo-biodegradable plastic is ideal for frozen food packaging, as it can be kept
for extended periods at low temperature, and will quickly degrade when it
becomes a waste product at normal temperatures.



In Brazil more than 20 cities have issued a direction that the city authorities
and all their suppliers use only oxo-biodegradable plastic for their packaging,
bags, and refuse sacks.



If people want to incinerate oxo-biodegradable plastic with heat recovery, or
recycle them, or re-use them, then that can be done.  The key point is what
happens to the plastic which is not collected, and gets into the environment as
litter.  Conventional plastic will lie around in the environment for many
decades, but d2w(R) will degrade in a short time leaving no harmful residues.



Biodegradable plastics have been supplied in UK supermarkets for more than three
years but there is no evidence that they have caused any increase in litter.



Oxo-biodegradable plastic also has useful applications in agriculture. For many
years farmers and growers have used plastic sheets to protect their crops but
after the crop has been harvested many thousands of square kilometres of dirty
plastic have to be removed and disposed of. This is a very expensive process,
and creates huge quantities of contaminated waste.



Oxo-biodegradable plastic sheets can however be programmed at manufacture to
degrade soon after the harvest. The fragments can then be ploughed into the soil
where they complete the biodegradation process and become a source of carbon for
next year's plants. Symphony has trials ongoing with a new additive specially
formulated for this purpose.
