January 10, 2005

Introduction

ò SOLAE is a soy protein based, food ingredient manufacturer with its largest of 11 plants located in Memphis, TN. SOLAE is a joint venture company majority owned by DuPont.

ò The BFI South Shelby Landfill is approximately 5 miles away from the SOLAE Plant

ò SOLAE works with BFI Allied Waste and CPL in order to understand landfill gas and its potential use for their facility in Memphis.

2 2

Introduction

ò Development issues on the three (3) boilers is discussed with reference on how to allow for mixture natural gas with the new LFG

ò CPL develops the strategy for SOLAE on how the LFG will integrate with the boilers and existing control systems.

ò SOLAE contracts with MLGW to install 5 mile pipeline from the BFI site to SOLAE‘s plant across public and private land.

ò Key concerns were reliability, cost savings and environmental impact

Environmental ò Final Environmental Statement: {The SOLAE Project while utilizing the 3500 scfm / year of landfill gas as

a fuel source in lieu of fossil fuels yields the same reduction in greenhouse gases as removing over 71,600 cars from the area roads for one year or utilizing the same greenhouse gas reductions as planting 96,800 acres of trees.}
