Item 4   Summary of Material Change
         --------------------------

VANCOUVER, CANADA, May 23, 2007 - Dynamotive Energy Systems Corporation
(OTCBB: DYMTF), announced it completed the initial production run of
BioOil(R) in its new generation plant in Guelph, Ontario, Canada.
Intermediate grade BioOil(R), which has higher calorific value than
regular BioOil(R), was produced.  The run is the first of a number of test
runs planned that are designed to take the plant to full production in
accordance with the commissioning plan underway.  Approximately 40 cubic
meters of wood were processed. The first run was at the equivalent daily
rate of 50 tonnes of feedstock processed and the second at a rate of 100
tonnes. Dynamotive and Tecna's engineers are currently reviewing
operational data and testing is being conducted on the fuel produced.
Data will be posted on Dynamotive's website www.dynamotive.com as it
becomes available.

5.1 Full Description of Material Change

VANCOUVER, CANADA, May 23, 2007 - Dynamotive Energy Systems Corporation
(OTCBB: DYMTF), announced it completed the initial production run of
BioOil(R) in its new generation plant in Guelph, Ontario, Canada.
Intermediate grade BioOil(R), which has higher calorific value than
regular BioOil(R), was produced.  The run is the first of a number of test
runs planned that are designed to take the plant to full production in
accordance with the commissioning plan underway.

Approximately 40 cubic meters of wood were processed. The first run was
at the equivalent daily rate of 50 tonnes of feedstock processed and the
second at a rate of 100 tonnes. Dynamotive and Tecna's engineers are
currently reviewing operational data and testing is being conducted on
the fuel produced.  Data will be posted on Dynamotive's website
www.dynamotive.com as it becomes available.

Dynamotive plans to market this renewable fuel with the name 'BioOil
Plus' as a green and cost competitive alternative to heating oil, fuel
oil, natural gas and propane in industry.  Industrial fuels represent
approximately 20% of hydrocarbon use worldwide.

Further, Dynamotive demonstrated in earlier tests that BioOil Plus can
be used as an input to Biomass to Liquid Processes (BTL) as a cost
effective means of delivering biomass energy to these plants and in
doing so break down cost and logistic barriers to the production of
mobile fuels from biomass. Specification on BioOil Plus and industrial
application information for the fuel are available at the company's
website.

"Cellulose-based fuels present the next frontier in sustainability and
Dynamotive's pioneering position in advanced generation biofuels is
further enhanced through the achievement of this new milestone.
Dynamotive believes that BioOil presents a third alternative liquid fuel
to coexist with ethanol and biodiesel," said Dynamotive's President and
CEO Andrew Kingston. "By being able to exploit any cellulose raw
materials, e.g. forest industry residues, bark, biomass from fields I
believe we can become a great contributor to the energy mix and
accelerate the adoption of cellulose based fuels."

Recently, at a renewable energy conference in Buenos Aires, Argentina,
Kingston announced that the company reached an agreement in principle
with the Provincial Government of Corrientes, in northeast Argentina,
for Dynamotive, its affiliate, local and international partners to
develop, subject to financing and other conditions, six similar plants
in that country at a total estimated cost of US $120 million.

Dynamotive has its other plant in West Lorne, Ontario, located midway
between Toronto and Detroit, Michigan now undergoing an upgrading of its
systems; information on this plant operations and the status of the
current upgrade can also be followed in the company's website.

About BioOil(R)

BioOil(R) is an industrial fuel produced from cellulose waste material.
When combusted it produces substantially less smog-precursor nitrogen oxides
('NOx') emissions than conventional oil as well as little or no sulfur oxide
gases ('SOx'), which are a prime cause of acid rain.  BioOil(R) and BioOil
Plus are price-competitive replacements for heating oils #2 and #6 that 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. BioOil(R)
can be produced from a variety of residue cellulosic biomass resources and is
not dependent on food-crop production.



About Dynamotive

Dynamotive Energy Systems Corporation is an energy solutions provider
headquartered in Vancouver, Canada, with offices in the USA, UK and Argentina.
Its carbon/greenhouse-gas-neutral fast pyrolysis technology uses medium
temperatures and oxygen-free conditions to turn dry, waste cellulosic biomass
into BioOil(R) for power and heat generation. BioOil(R) can be further
converted into vehicle fuels and chemicals.  The final stages of the
commissioning process at the Guelph plant and the reconstruction of the West
Lorne plant may be seen by viewing photographs regularly posted on the
company's website at www.dynamotive.com
