VANCOUVER, CANADA, April 3, 2007 - Dynamotive Energy Systems
Corporation (OTCBB: DYMTF), a leader in biofuel technology and products
based on its advanced fast pyrolysis process, announced today that its
new flagship Intermediate BioOil plant in Guelph, Ontario, was 'hot
commissioned' on March 30th on schedule. Preparations are now
continuing for initial production expected later this month.  It was
also announced that the civil works phase has now commenced at the
Company's West Lorne, Ontario, BioOil plant, which is being upgraded
prior to renewed production of BioOil to fuel the 2.5 MW gas turbine.
The upgraded reactor and burner systems are ready for shipment and the
plant is expected to be operational towards the end of this quarter.

5.1  Full Description of Material Change

VANCOUVER, CANADA, April 3, 2007 - Dynamotive Energy Systems
Corporation (OTCBB: DYMTF), a leader in biofuel technology and products
based on its advanced fast pyrolysis process, announced today that its
new flagship Intermediate BioOil plant in Guelph, Ontario, was 'hot
commissioned' on March 30th on schedule. Preparations are now
continuing for initial production expected later this month.

It was also announced that the civil works phase has now commenced at
the Company's West Lorne, Ontario, BioOil plant, which is being
upgraded prior to renewed production of BioOil to fuel the 2.5 MW gas
turbine. The upgraded reactor and burner systems are ready for shipment
and the plant is expected to be operational towards the end of this
quarter.

Dynamotive President and CEO, Andrew Kingston, said "The hot
commissioning went well and results point to an initialization of
actual production of biofuel later this month.  Clearly, it is a step-
by-step process as we are dealing with a variety of systems that need
to be brought up to optimum operational capacity over a certain,
specified period of time.

"Aside from a short period of poor weather, we have been able to
maintain schedules.  The construction itself has shown that the modular
design has worked well from the point of view of it being potentially
feasible to transport an entire plant to almost anywhere in the world
by road."

Kingston said that the West Lorne plant is now in the civil works phase
with all the dismantling completed. "The key components of the upgraded
design, such as the new reactor, have been built and are awaiting
installation. Also, all contracts relating to the project are basically
in place and we are on track to be operational by the end of the second
quarter."

The Guelph plant will be operated by Evolution Biofuels Inc.
Dynamotive has retained a minority ownership position in Evolution
Biofuels and will lease the plant to the majority owner.

BioOil produces substantially less smog-precursor nitrogen oxides 'NOx'
emissions than conventional oil as well as little or no sulphur oxide
gases 'SOx', a cause of acid rain.  BioOil and Intermediate BioOil are
price-competitive replacements for heating oils #2 and #6 which are
widely used in industrial boilers and furnaces.  They have been EcoLogo
certified, having met stringent environmental criteria for industrial
fuels as measured by Environment Canada's Environmental Choice Program.
