World Waste Technologies and Ensyn Corp Sign MOU Regarding Proposed Technology Development Pact; Companies Target Generating Bio-Fuels From Cellulose
Monday April 30, 8:00 am ET

World Waste Technologies Files Lawsuit Against Vessel Designer

SAN DIEGO, Calif., April 30, 2007 (PRIME NEWSWIRE) -- World Waste Technologies, Inc. (OTC BB:WDWT.OB - News):

Technology Development MOU

World Waste Technologies and Ensyn Corporation today announced they have entered into a memorandum of understanding relating to a proposed technology research and development arrangement under which the companies would collaborate to develop technologies for production of energy products and bio-fuels from cellulose biomass derived from post-recycling municipal solid waste.

Based in Wilmington, Delaware, privately held Ensyn Corporation developed the patented RTP(tm) process in early 1980s, converting wood residues and other biomass products to a light, liquid bio-oil for the production of fuels and chemicals. Ensyn's commercial biomass operations were initiated in 1989, and there are now seven commercial RTP(tm) biomass plants in operation, producing numerous chemical products and fuels. In 1997, Ensyn adapted its RTP(tm) process to the upgrading of petroleum feedstocks (heavy oil). In 2005, Ensyn sold all rights related to RTP(tm) upgrading of petroleum to Ivanhoe Energy, Inc.

Although Ensyn's bio-oil can be used directly as a liquid fuel, it contains a number of valuable natural chemicals (primarily resins) believed to be economically recoverable and used as a raw material for the production of value-added natural chemicals and bio-fuels. There are many environmental benefits associated with the production of natural chemicals and bio-fuels via RTP(tm). For example, such fuels and chemicals are renewable, they are low sulphur, and their production nets no new CO2 production. The use of wood and other biomass residues in the RTP(tm) process reduces solid-waste disposal problems in certain industries and displaces the use of non-renewable petroleum feedstocks.

Based upon recently completed favorable preliminary test results from the application of Ensyn's technology using World Waste's post-recycled MSW cellulose biomass (``Cellulose''), the companies hope to jointly develop their technologies with the plan to ultimately target commercial production of bio-fuel from Cellulose. The companies plan to conduct development work at Ensyn's state of the art technology center near Ottawa, Canada. The companies plan to evaluate their development efforts later this year to determine the feasibility of extending or expanding the collaboration into a more formal strategic alliance.

``The opportunity to convert municipal solid waste into bio-fuel borders on revolutionary, both economically and environmentally,'' said Dr. Robert G. Graham, Ensyn chairman and chief executive officer. ``We believe that World Waste has strong technology platforms and innovative management and Ensyn is excited to have the opportunity to work to advance these technologies.''

``We believe that Ensyn Corp is a true pioneer and respected market leader in bio-fuel production with a strong track record of commercial success,'' said John Pimentel, World Waste chairman and chief executive officer. ``I believe our technologies offer great synergy, and we are delighted to be working closely with Ensyn's world class R&D team.''

Ensyn has several commercial plants in production in Wisconsin and Ontario, Canada. These plants have been used commercially since the early 1990s to produce energy and more than thirty chemical products.

World Waste Technologies, Inc. was formed to design, build, own and operate facilities which convert municipal solid waste (MSW) into higher value products such as cellulose biomass, ethanol, renewable electricity and paper pulp. World Waste is also striving to develop technologies to use thermal conversion processes to generate renewable energy and bio-fuels such as ethanol.

Lawsuit

As previously disclosed during the start-up phase of its initial plan in Anaheim, California, World Waste became aware of design issues related to the steam classification vessels that it intends to use in its operations. The steam vessels were designed and fabricated on its behalf by Bio-Products International, Inc. (``BPI'') pursuant to a contract World Waste entered into with BPI in July 2004. World Waste is also party to a sub-license agreement with BPI pursuant to which World Waste sub-licenses certain technology used in its process. World Waste has been dissatisfied with the remediation of these issues by BPI and has proceeded to resolve them itself. Consequently, on April 13, 2007, World Waste filed a lawsuit against BPI in the Superior Court of the State of California alleging, among other things, breach of contract and negligence with respect to the construction of the vessels. World Waste is seeking monetary damages, among other relief sought. Although it cannot ascertain what the outcome of this litigation will be, World Waste plans to pursue this matter vigorously.

World Waste Technologies Applies for Patent Covering the Production of Alcohol, Including Ethanol, Through Gas Process
Monday March 5, 5:00 am ET

Company Also Forms Technology Advisory Board Comprised of Scientific and Industry Experts and Provides Updated Operational Information

SAN DIEGO--(BUSINESS WIRE)--World Waste Technologies, Inc. (OTCBB:WDWT - News) today announced it has filed a provisional patent covering an energy self sufficient process for the treatment of municipal solid waste (MSW) into the production of mixed alcohols (including ethanol) through a synthetic gas and catalyst process. The process also includes the co-generation of renewable electricity from a producer gas as well as a process for efficiently separating the resulting mixed alcohols from hydrocarbons and other liquids.

Separately, the Company announced the formation of a Technical Advisory Board to assist it in advancing its business of creating usable commodity products including ethanol and co-generated renewable electricity from municipal solid waste. William A. Farone, Ph.D. and Lee Torrens, along with World Waste Director David Gutacker, have agreed to serve on this advisory board.

Dr. Farone is focused on assisting World Waste in identifying chemically and economically preferred methodologies for producing ethanol and other renewable energy products from municipal solid waste. Dr. Farone is the President and CEO of Applied Power Concepts, Inc., a company that provides technology development and analysis services and has expertise in chemical and biochemical process development and optimization, particularly in the areas of alternative energy, biotechnology for energy crops, and alternate liquid fuels (ethanol, methanol). Formerly Dr. Farone was Director of Applied Research for Philip Morris, Inc., and also served as Director of Scientific Research at Lever Brothers Company. He has numerous patents and technical publications, a B.S. and Masters degree in Chemistry, and a Ph.D. in Physical Chemistry.

Lee Torrens is focused on assisting World Waste in the scale-up and development of facilities that produce ethanol and other energy products from municipal solid waste. Mr. Torrens has an extensive background in developing renewable energy facilities, independent power production facilities, cogeneration facilities, waste to energy facilities, and medical waste facilities. Formerly, Mr. Torrens served as Executive Vice President of Ogden Martin Systems where he was responsible for all project development activities at a time when that company developed eight major projects worth over $840 million. In addition, Mr. Torrens is currently a Director and Principal of JM Dutton & Associates, an independent equity research company. Mr. Torrens has a B.S. and a Masters degree in Civil Engineering.

"The skills and background of both Bill Farone and Lee Torrens are strong assets for World Waste as we continue our efforts to develop projects and technologies for the transformation of municipal solid waste (MSW) into beneficial products, including fuel grade ethanol, co-generated renewable energy, and paper pulp," said CEO John Pimentel. "We have already benefited from their efforts through their help in our provisional patent application for a new method of creating fuel alcohols including ethanol from MSW through a synthetic gas intermediary step, and our work with various gasification processes."

"By utilizing our Anaheim Plant and the Applied Power Concepts labs in Anaheim as our learning centers, we believe that we have gained valuable experience in understanding how to commercialize the process of transforming residual and commercial MSW into beneficial products and energy," said Pimentel.

Company Update

To date, World Waste has focused on converting MSW into a cellulose biomass which the Company currently refines into an unbleached fiber known in the paper industry as "wetlap pulp". The Company has also been investing in potential improvements to the core process designed to produce fuel grade alcohols, including ethanol, as well as processes for co-generating renewable electricity.

Ethanol and Co-Generated Renewable Energy

The Company has also been pursuing the development of various energy products which can be produced from MSW. One process which we believe has potential for successful commercialization involves using gasification technologies to produce a synthetic gas from various products in our process. This gas may then be passed through a catalyst environment to produce fuel grade alcohols, primarily ethanol, with some portion of the gas stream co-generating renewable electricity. We believe this same basic approach can also be used to produce hydrogen, a critical element in many current industrial processes and to several future clean energy platforms. In this area the Company recently filed a provisional patent covering a process and certain conditions which may maximize the yield of the fuel alcohols including the beneficial co-generation of renewable electricity through a producer gas which may drive a steam or a gas turbine.

Also in the ethanol area, in addition to the above process for producing fuel alcohols through gasification, the Company is investigating alternative pathways for transforming its cellulose biomass product into ethanol using various acid and enzymatic hydrolysis processes.

Pulp Process

In the MSW/cellulose biomass to wetlap pulp product area at its Anaheim, California Plant, World Waste has processed, over a seven month period, over 2,500 tons of MSW into cellulose biomass, which has been refined into over 400 tons of wetlap pulp. Although we have not yet been able to produce product in commercial quantities, the wetlap product has been supplied to three corrugating medium manufacturers in Southern California over this period on a test basis. The customers have recently provided positive feedback on the pulp quality and specifications, based upon these limited test quantities. World Waste recently developed a commercial relationship with one of these customers whereby that customer, although not contractually obligated to do so, is currently purchasing all the product World Waste is capable of producing at market prices consistent with terms commonly used for the sale of recycled corrugated containers, OCC, exported from the Los Angeles region.

The start up and operation of the Anaheim Plant was made possible through a series of equipment upgrades financed from the proceeds of our Series B offering completed in the first half of 2006. "We deeply appreciate the support of our investors which has enabled us to start operations at the Anaheim Plant. This has provided us actual operating data and insights as to what additional investments would be required to make the Anaheim Plant support full capacity operations, as well as insights on the critical improvements which must be included in the design and construction of future pulp-based plants for those future plants to generate sufficient financial returns," said Pimentel.

Key challenges that faced at the Anaheim Plant include an unexpectedly high level of biochemical oxygen demand (BOD) from organic wastes in the wastewater generated in the pulp screening and cleaning process, and design issues related to the steam classification vessels which will require some level of re-engineering and repairs to enable sustained operations. These factors currently restrict full scale, profitable operations at the Anaheim Plant and have led to management's decision to reduce the workforce and to run the plant on an intermittent basis for process improvement trials, technology demonstration, product development, and other research and marketing purposes. These restricted operations allow us to continue evaluating several initiatives, some of which include additional capital investment, in an attempt to improve these conditions and to improve the economics of operating the Anaheim plant.

To manage the continued operations of the Anaheim Plant and to lead the planning and design for future plants, Dr. James Ferris, the Company's Chief Operating Officer and President (and member of the Board of Directors), has taken on increased responsibility at the Anaheim facility. Mr. Fred Lundberg has stepped down from his position as Senior VP of Engineering, but will continue to serve the Company in an advisory capacity.

Based on our research and development including our accumulated experience from operating the Anaheim Plant, World Waste believes the characteristics necessary to profitably produce pulp include: a relatively high volume of MSW and a larger plant enabling a larger scale operation, a desire by the community to increase recycling rates to minimize the amount of this waste disposed of in landfills, feedstock composition which includes increased paper products, a fully scoped on-site water treatment facility, and higher landfill tipping fees than we experience in Anaheim, California. Regarding the paper "wetlap" product line, World Waste has continued its discussions with various paper and solid waste companies and government agencies to determine where the proper combination of operating characteristics can be achieved to pursue a larger scale wetlap production facility in future locations. While developing the process and market for wetlap, the Company has also been actively pursuing end markets for our raw cellulose biomass material prior to its use as a feedstock for making wetlap pulp. This would allow the Company to avoid the capital and operating costs of a water treatment facility to address the BOD issue.

World Waste Technologies Announces Initial Test Shipments of Quadra C Unbleached Pulp
Wednesday July 5, 6:00 am ET

World Waste Technologies, Inc. announced today that it has completed the initial test shipments of its unbleached fiber pulp product, Quadra C Unbleached pulp, to prospective customers. World Waste shipped a total of three truckloads of product, containing approximately 20 tons of material each, to three potential customers in the Los Angeles, California area. The product was delivered without charge pursuant to a previously agreed-upon trial phase with these potential customers designed to enable them to begin to evaluate the product in connection with possible future purchases by them at market prices and on a commercial scale. The material was successfully blended into the raw material furnish at approximately 10% concentration for the production of packaging grades at each of the potential customer's paper making plants.

After the last of the initial test shipments was made on June 26, 2006, World Waste began a plant "wash-up" which involves suspending operations for a two week period, in order to install additional processing equipment. After this period, World Waste plans to continue limited test shipments free of charge to its customers. The company currently anticipates that the controlled startup of the plant will continue through at least the end of 2006 and that therefore only limited revenue will be generated through the remainder of the year. During this controlled startup the Company will be implementing a process optimization program including continual monitoring, measurement and analysis of plant operations, the installation of additional equipment that the company deems necessary for the plant to operate more efficiently. This additional equipment includes but is not limited to equipment to remove the biochemical-oxygen demand, BOD in its water effluent. The installation of additional equipment may cost several million dollars before the plant can reach full operating levels.

Separately, the company announced the final results of its recent offerings of preferred stock and warrants and related senior secured note exchange. Pursuant to these transactions, the company issued $28.5 million total face amount of its Series B convertible preferred stock, convertible into 11.4 million shares of common stock, and warrants to acquire 2.85 million shares of common stock, in exchange for total gross cash proceeds of $25.0 million and the cancellation of $3.5 million of senior secured notes. After applying $2.9 million of these proceeds to the repayment of the company's remaining obligations on its senior secured notes and $2.4 million to offering costs, the company generated net cash proceeds of approximately $19.7 million. As previously disclosed, the company plans to use these net proceeds for commissioning, operation, and process improvement investments at the company's recently completed initial plant located in Anaheim, California, and for working capital and general corporate purposes.
