5. The Markets -- Photowaste Services, Silver, and Fertilizer The U.S. Environmental Protection Agency says silver bearing photoliquids were a 100 million gallon toxic waste stream in the U.S.; today 50 million. Management of silver bearing waste streams required under U.S. EPA RCRA because EPA data shows silver in water is toxic to fish. Regulatory authorities are encouraging development of recycling technologies that increase the amount of materials used beneficially.

6. Photosilver Disposal in the US 45 million troy ounces of silver is used in photography in US; 10 million ounces end up in liquid photo waste Silver must be removed from photo waste; methods include: – Partial de-silvering on site followed by discharge to sewer –Capture at the source, de-silvering off site, transport to sanitary or hazardous waste land fill –Capture at the source, de-silvering and concentration off site followed by incineration Itronics has pioneered Silver Thiosulfate recycling, a new option for completely converting liquid photo waste to beneficial use

7. Photowaste in the U.S.A Photo waste is generated by medical, dental, veterinary, and consumer photo processing. Well known companies such as Walmart and Costco and many drug and grocery store chains offer digital and conventional photo print production. Hauling and disposal services are provided by national Companies such as Safety-Kleen and Philip Environmental Services and by smaller regional companies.

8. The Markets --Photowaste Services Silver and Fertilizer Using Itronics technology, 50 million gallons of waste photoliquids are sufficient to manufacture 100 million gallons of GOLDn GRO fertilizers, or 500,000 tons 50 million gallons of photowaste contains about 10 million ounces of silver; today worth about $170 million Itronics estimates the market targeted for its services and products is approximately $1 billion in the U.S. The total fertilizer market in the U.S. is 50 million tons, a market of approximately $18 billion

9. Itronics Recycling Technology Advantages Achieves complete resource use!! Only fully permitted photo waste to silver and fertilizer facility in the United States!!! Removes 100% of silver and converts residuals to usable products. Environmentally compatible GOLDn GRO fertilizer manufactured from liquid portion. Silver extracted from solid portion.
