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

VANCOUVER, BC, Canada, August 30, 2007 - Dynamotive Energy Systems
Corporation (OTCBB:DYMTF) announced today that its net loss for the
second quarter ended June 30, 2007 was $3.5 million, or $0.02 per
share, compared with a net loss of $3.8 million, or $0.02 per share for
the same period a year ago. The lower overall loss represents more
activity in almost all business areas, partially offset by lower non-
cash charges.

"During the second quarter and since it ended June 30th, the Company
continued to make significant progress as we ready our new modular 200
tonne-per-day Guelph, Ontario, BioOil(R) biofuel plant for full
operation," commented Andrew Kingston, Dynamotive's president and chief
executive officer. "Recent business developments which will help pave
the way for the company's future growth include reaching a letter of
agreement with Mitsubishi Corporation and deepening our relationship
with the Consensus Business Group through the merger of a jointly held
affiliate into Dynamotive."

5.1 Full Description of Material Change

VANCOUVER, BC, Canada, August 30, 2007 - Dynamotive Energy Systems
Corporation (OTCBB:DYMTF) announced today that its net loss for the
second quarter ended June 30, 2007 was $3.5 million, or $0.02 per
share, compared with a net loss of $3.8 million, or $0.02 per share for
the same period a year ago. The lower overall loss represents more
activity in almost all business areas, partially offset by lower non-
cash charges.

"During the second quarter and since it ended June 30th, the Company
continued to make significant progress as we ready our new modular 200
tonne-per-day Guelph, Ontario, BioOil(R) biofuel plant for full
operation," commented Andrew Kingston, Dynamotive's president and chief
executive officer. "Recent business developments which will help pave
the way for the company's future growth include reaching a letter of
agreement with Mitsubishi Corporation and deepening our relationship
with the Consensus Business Group through the merger of a jointly held
affiliate into Dynamotive."

"Initial revenue from the Guelph plant and the expanded West Lorne
operation will commence in the near future, and our business
development position will improve significantly as we enter operating
status," Mr. Kingston noted. "As we approach operating status at these
two plants, international interest is growing, with advanced
development activities in Europe and South America, and accelerating
project development activity occurring in the United States."

Concluding his remarks, Mr. Kingston said: "With the continued
volatility and insecurity of world energy markets and ever greater
attention being paid to environmental issues, Dynamotive is also well
positioned to be a leader in the Biomass to BioOil sector of the
alternative energy market."

Recent Dynamotive Highlights:

- - Signed a detailed Letter of Agreement with Mitsubishi Corporation to
explore expanded relationships
- - Consensus Business Group converted their biomass JV interest into
Dynamotive equity and appointed a director to Dynamotive's Board
- - Development of up to six plants in Corrientes, Argentina continues
- - Commissioning and permitting of first 200 tonne-per-day (TPD) plant
at Guelph, Ontario nears completion
- - West Lorne expansion nearing mechanical completion, commissioning to
begin late next month
- - Initiated tests in Iowa to use Dynamotive's biochar for soil
enrichment and crop productivity enhancement
