Definitions

• Waste Paper (WP)- newspapers, food

packaging, tissues, cardboard boxes,

• ffice paper, paper plates, etc.
• EtOH – fuel ethanol

Background

Energy Shortages & Oil Depletion

– Petroleum and natural gas account for

• approx. 65% of US energy supply

– Oil demand increases at a rate of 2% a year – Demand and consumption is far greater than supply and production

Background

Fuel Solutions

• Conversion of waste paper to energy
• US paper products make up 31-38%

composition of landfills

• Today over 51 million tons of paper and

paper products are being recycled annually

Existing EtOH Plants

• 116 ethanol plants

– Generating 5536 million gallons per year – Mostly corn based – No waste paper based

• Plant to be built in Greece, NY

– 15,000 square feet plant – Will produce 500,000 gallons per year

Our Design

Process Flow

– Pretreatment – Enzyme Hydrolysis – Fermentation – Separation

Block Flow Diagram Challenges

• Choice of Enzyme and Yeast

– Yeast versus Bacteria (Yield) – Cost

• Collection and Transportation of

Free Waste Paper

– Low Cost, No Cost or Paid

Cost of EtOH

• Raw Materials

– Waste Paper – Water – Enzyme – Yeast

• Capital Costs

– Cost of each piece of equipment using CAPCOST program

• Operating Costs

Locations for Plant

• Enterprise South
• On Tennessee River
• Soddy Daisy / Sale Creek

Partnerships

• City of Chattanooga
• Department of Energy

– Six cellulosic ethanol plants for up to $385 million in federal funding
