Commercial-scale sorting of titanium alloys started in 2005. Sorting of aluminum alloys started in 2006 and superalloy sorting is expected to commence in 2008. In addition to the quantitative case studies, qualitative analysis was conducted for three additional green process technologies. Sorting of High-Value Engineered Plastics Engineered thermoplastics are high-value components extensively used in personal computers, appliances, automobiles, and other durable goods. Given the complex variety of these thermoplastics, their recycling and recovery rates are very low, resulting in the loss of valuable petrochemical content and large waste streams that choke landfills and create toxic fumes when incinerated. With ATP funding, MBA Polymers, Inc. of Richmond, California developed a proprietary plastics sorting technology to cost-effectively segregate engineered plastics by type and by grade. Green benefits from this ATP-funded innovative process technology include the following: • Increased recycling and reduced landfilling of thermoplastics waste • Avoided use of petroleum-derived feedstock in virgin plastics production • Reduced greenhouse gases After completion of the ATP-funded project, MBA Polymers raised over $30 million in equity investments to fund the construction and operation of two industrial-scale plastic sorting facilities, each with a design capacity of 40,000 metric tons per year. Molecular Gates Technology for Cost-Effective Purification of Natural Gas Natural gas from coal mining and some natural gas reserves requires nitrogen removal and upgrading to pipeline-quality gas. With ATP funding, Engelhard Corporation (now BASF Catalysts) of Iselin, New Jersey developed the molecular gates or molecular sieves gas separation technology for cost-effective treatment of small-volume natural gas flows. Green benefits include the following: • Commercially viable gas separation from smaller coal mines and small-output natural gas wells, reclaiming natural gas that otherwise could not be economically reclaimed • Removal of hazardous gases from coal-mine formations to reduce the danger of mine explosions and fires To date, Engelhard Corp. has sold 18 molecular gate gas separation systems for nitrogen rejection, with half of these units installed in coal mines. 4 ATP-FUNDED GREEN PROCESS TECHNOLOGIES
High-Intensity Ultraviolet Lamp Systems for Water Treatment and Paint Stripping With ATP funding, Phoenix Science & Technology, Inc. of Chelmsford, Massachusetts developed a new, high-intensity, ultraviolet (UV) lamp system— without using mercury gas—and demonstrated its technical feasibility. Early commercialization efforts are underway. After commercialization is achieved, the green benefits of using high-intensity UV lamps for water treatment and lead paint–stripping applications are expected to include the following: • Reduced rates of childhood lead poisoning and reduced levels of chemical and blast media byproducts from paint stripping • Improved quality of treated water supplies • Avoided disposal of toxic mercury waste at the end of UV lamp product life Introduction 5
