About GRI: The route to Zero Waste Worldwide 10 million tons of wallboard waste are presently landfilled causing environmental and political difficulties These 10 million tons might as well be used in an beneficial manner instead of wasted ! Recycling is the only solution that keeps the waste out of the landfills and preserve natural resources at the same time – Zero Waste Recycling will limit the amount of greenhouse gasses created (landfills are among the most important contributors to global warming) All mega-trends are with recycling – and against landfilling. The landfill alternative is in trouble on a worldwide scale !! We send nothing to landfill in our operations; all materials received are reused one way or the other; recycled gypsum for wallboard production, paper for composting and metals for recycling – Zero Waste

About GRI: In cooperation with the best GRI serves all the top wallboard manufacturers in the world. In the US we are proud to cooperate with the two biggest manufacturers, for the supply of recycled gypsum. In New England we deliver to USG: Charlestown National: Portsmouth, NH US Gypsum National Gypsum

Update on Mass. operations = Gypsum Recycling America Started visiting Mass in 2004 In 2004/05 contracts with the US manufacturers were made End of 2005 Boston warehouse was established and permitted; Fawcett Street 135, Cambridge; 5-8 miles to Boston downtown close to interstate highway system Slowly opened for business end of 2006 Machine finally delivered summer of 2007 Full speed ahead since end of 2007 Organizational set up: John Fitzgerald, Regional Manager Patrick Manning, Sales manager

Update on Mass. operations – offer to customers Enviromental friendly recycling of their materials – Zero wasted Cheaper than landfill disposal Collection service – 30 cubic yards containers with top lids to keep materials dry Fixed price per dumpster (app. 500$ per conntainer). This is an ”all in price”; no fuel, environment or other fees added on top, and there is no limit on the tonnage. Gate delivery to our warehouse also possible at 14 $ per cubic yard. Customers include: General contractors, construction companies, pre-fab housing manufacturers and drywall hangers Transfer stations, recyclers/processors, waste haulers, waste management companies, landfills and potentially municipalities Both from Mass. and from other states !

Market outlook and barriers for expansion in Mass. Generally good reception Increasing interest LEED Customers outside Mass. Despite lack of recycling cul-ture, the quality of the received waste is generally good Next: more warehouses in Mass (Springfield and Worcester) and opening of warehouses outside Mass. Barriers for expansion Only new construction waste initially allowed (only GRI site with this limitation) Limited support from regulations/policies; => high reliance on market mechanisms No required source segregation No special regulations on how to handle gypsum waste in landfills No landfill tax Limited municipal recycling centers infrastructure No ban on out of state export of waste No requirements for recycling of waste or use of recycled materials when public authorities are awarding contracts Limited initiatives to limit global warming / the creation of greenhouse gasses in landfills by making landfilling more and more unattractive. Landfills are responsible for 7% of the greenhouse gasses created in the US !!
