TAMPA, FL -- (MARKET WIRE) -- 09/19/07 -- EarthFirst Technologies, Incorporated ("EarthFirst" or "the Company") (OTCBB: EFTI) announced today that Renewable Carbon Technologies, LLC ("RCT"), a joint venture between EarthFirst and Orion Industrial Services ("OIS"), has entered into a Memorandum of Understanding ("MOU") with Phoenix Energy Systems, Inc. ("Phoenix"), to deliver ten Catalytic Activated Vacuum Distillation ("CAVD") plants in the Caribbean basin and the European Union.

The detailed MOU calls for the parties to finalize a Master License Agreement that will become effective after demonstration of the Mobile, Alabama plant. Upon execution of the Master License Agreement, Phoenix has agreed to order a CAVD unit for the continuing development of its "Energy Island" in Kingston, Jamaica. Construction of the Kingston unit could begin as early as March 2008.

Randy L. Thomas, Phoenix's CEO and President, signed the MOU after receiving a financial commitment from an international bank for its Kingston Energy Island. Phoenix intends to incorporate other proven, high-tech, award-winning waste-to-energy technologies into Energy Island (see www.phoenixenergysystems.com).

Mr. Thomas stated, "We are all systems go for our one stop waste-to-energy project. We will employ multiple cutting-edge technologies to recover energy from a variety of waste streams that are generated on the island of Jamaica. Our ability to de-construct (de-polymerize) tires is an important part of our processing capability on this project and we are pleased to have chosen RCT's CAVD as our tire remediation module. We studied RCT's CAVD process and all major industry competitors and concluded that the RCT's CAVD is the best available technology to integrate with our waste-to-energy process and the CAVD proprietary method of de-constructing tires will soon become a day in, day out commercial reality. In conclusion, we believe that RCT's CAVD will produce high-value commodity by-products that are beneficial to our process, will reduce our electric demand and carbon footprint, without producing any of the harmful emissions that are associated with the manufacture of similar virgin products."

John Kateon, RCT's managing member, was pleased with Phoenix's selection of the CAVD technology saying, "The Phoenix MOU validates the OIS commitment to partner with EFTI in finalizing CAVD development. We have built on EFTI's vision by adding our own pyrolysis intellectual property and experience. The Phoenix transaction should be just the first step in the proliferation and mainstream acceptance of the CAVD technology and I am hopeful that after final proof of concept in Mobile, scores of CAVD facilities will spring up around our country and the world and helping to finally solve the nagging problem of waste tire disposal."
