CleanTech is excited to begin this testing and about the potential impact of our technologies for the reduction of garbage being disposed of in landfills worldwide. It is estimated that Americans produce 4.4 pounds of waste per day, or 229 million tons of trash annually nationwide. This waste represents a virtually endless source of cellulosic feedstock for the production of biofuels that potentially will be available to CleanTech at almost no cost, and in some locations at a profit.

The waste disposal crisis in this Country, coupled with the Energy Independence and Security Act of 2007 which dictates that production of ethanol in the United States reach 36 billion gallons per year by the year 2022, of which 20 billion gallons per year is required to be produced from feedstock sources other than corn, positions CleanTech Biofuels to be a leader in the cellulosic ethanol industry.

CleanTech Biofuels, Inc.

CleanTech Biofuels, Inc. is a development stage company that is developing cutting edge waste to clean fuel technologies. We have licensed and are developing our core patented technologies which, when combined, can be used to convert the cellulosic material in municipal solid waste, green waste, and other cellulosic waste materials into fermentable sugars for the production of ethanol.

Our unique technology package positions us to be the industry leader in using municipal solid waste (MSW) as the primary feedstock for energy production. Municipal biorefineries developed using our technology have the potential to:

* Reduce the costs of transporting waste long distances for disposal.
* Dramatically reduce pollution released into the environment by the disposal of municipal solid waste.
* Reduce the amount of material going into landfills by as much as eighty five percent.
* Increase the amount of recyclable materials that can be recovered from municipal solid waste.
* Generate biofuels and other usable energy products at competitive prices.

We believe that our combined technologies will enable the production of ethanol from cellulosic waste streams at a lower cost than from grain or other agricultural feedstocks. Our combined technologies will avoid the immense consumption of water and farmland that plague grain ethanol producers, with the added benefit of recycling garbage and reducing the amount of waste disposed of in landfills by as much as ninety percent.

By focusing on cellulosic biomass produced from curbside garbage where an existing collection and disposal infrastructure has existed for many years, our business model presents substantial economic advantages relative to other models dependant on agriculturally derived feedstocks or wood waste for the production of cellulosic ethanol.

* Macy’s will replace the primary handled shopping bag used in its stores with one made from kraft paper with 30 percent recycled material. The new bag also is 100 percent recyclable. It replaces a laminated paper bag that is neither made from recycled content nor recyclable. In total, Macy’s uses more than 43 million handled shopping bags each year.
* In order to provide customers more options when making a purchase, all Macy’s stores will begin carrying reusable tote bags made from 100 percent natural cotton. The totes, created in partnership with Cotton Incorporated, will sell for $3.95, with $1 of the purchase price donated to the National Park Foundation. On Saturday, April 26, the first 100 to 150 customers at every Macy’s store will receive a free reusable tote bag.
* The company’s direct-to-consumer businesses – macys.com, bloomingdales.com and Bloomingdale’s By Mail – will begin using loosefill in-the-box packing material that is 100 percent biodegradable, compostable and recyclable. The material is used to prevent damage to fragile merchandise as it is shipped to customers. Previously, the company used “packing peanuts” (synthetic, non-biodegradable material) for this purpose. The new material is made from raw ingredients including pure corn and potato starch. It breaks down in water in nine minutes and will not harm the environment. Each year, Macy’s, Inc. uses approximately 3.1 million cubic feet of in-the-box packing material.
* Macy’s stores and macys.com will continue to use recyclable folding gift boxes and wrapping tissue made from 100 percent recycled material. Each year, Macy’s uses approximately 48 million folding gift boxes and 255 million sheets of wrapping tissue. Bloomingdale’s wrapping tissue (75 million sheets used each year) will be converted to 100 percent recycled material in spring 2008. In addition, Bloomingdale’s will offer a 100 percent recycled paper and ribbon gift-wrapping option for holiday 2008.

These actions are consistent with Macy’s, Inc.’s corporate strategy to adopt business practices that preserve and protect the environment.

“Our strategies for sustainability include aggressively reducing wasteful behavior, decreasing our use of scarce resources and pursuing environmentally friendly solutions whenever we have the option to do so,” said Macy’s, Inc. Vice Chair Tom Cole. “As a leading national retailer with a significant workforce, we have the opportunity to make a meaningful difference in improving the environment. And we will do so. But we must operate within the bounds of good business decision-making so that the actions we take are measurable, sustainable and enduring.”

By the end of 2008, the company will be hosting solar energy panels on more than 30 of its stores, primarily in California. Solar power, combined with energy efficiency projects, will reduce grid energy consumption by 40 percent in these stores. Energy consumption per square foot companywide has been reduced by about 9 percent over the past five years. And the amount of recycled paper used in advertising materials increased by about 10-fold in 2007 alone.

Beginning in April, as previously announced, Macy’s will partner with the National Park Foundation to educate shoppers and raise awareness and funds for parks across America. It will be launched during Earth Week in conjunction with Macy’s Turn Over a New Leaf campaign, which will include promoting eco-friendly merchandise and distributing free tree saplings to the first 100 customers in each Macy’s store on April 22.

Bloomingdale’s is partnering with the Natural Resources Defense Council to raise awareness and funds through a special electronic gift card (the “little green card”) available at all Bloomingdale’s stores and online.

“At Macy’s, Inc., we believe that contributing to a more sustainable environment is good business practice and the right thing to do for future generations,” Cole said.

Macy’s, Inc., with corporate offices in Cincinnati and New York, is one of the nation’s premier retailers, with fiscal 2007 sales of $26.3 billion. The company operates more than 850 department stores in 45 states, the District of Columbia, Guam and Puerto Rico under the names of Macy’s and Bloomingdale’s. The company also operates macys.com, bloomingdales.com and Bloomingdale’s By Mail. Prior to June 1, 2007, Macy’s, Inc. was known as Federated Department Stores, Inc.

RecycleBank motivates households and communities to recycle by financially rewarding each household for the amount they’ve recycled. RecycleBank’s proprietary technology measures the amount of material recycled and then converts the amount into RecycleBank Points that can be used at hundreds of local and national reward partners.

“Through our additional investment in RecycleBank, we are fulfilling our commitment to advance economically viable approaches to recycling collection in the communities we serve,” said Scott Vitters, director of sustainable packaging, The Coca-Cola Company. “We believe this program will revolutionize the way consumers view their trash, from disposables to valuable reusables.”

RecycleBank’s long-term connection with households enables reward partners like Coca-Cola to recognize the vast and unique marketing opportunities in RecycleBank. More than 300 local and national businesses have partnered with RecycleBank in order to reach the households that RecycleBank services.

Last year, RecycleBank and Coca-Cola formed the RecycleBank Donations Program. The program enables households to donate their RecycleBank Points to the Ocean Conservancy, a nonprofit organization committed to clean water issues and the RecycleBank Green Schools program which helps fund environmental initiatives at schools in RecycleBank areas. Coca-Cola pledged to match dollar for RecycleBank Point that was donated. Based on the success of the RecycleBank Donations Program in 2006, Coca-Cola has reconfirmed its commitment for another year long partnership to continue to sponsor these programs.

“Coca-Cola believed in RecycleBank when it was just an entrepreneur’s vision and has continued to support us since our launch,” said Ron Gonen, CEO of RecycleBank. “We are proud that our relationship continues to deepen with Coca-Cola as we work together on a number of activities to promote a more sustainable business community and to scale RecycleBank nationally.”

Following Coca-Cola’s investment, RRE Ventures and Sigma Partners remain as the largest institutional shareholder group and Ron Gonen, the co-founder and CEO, remains as the largest individual shareholder. RecycleBank currently provides service in New Jersey, Delaware and Pennsylvania and will be launching service nationally in 2008.
