Transcription

1 PEAT International Transforming today s WASTE into tomorrow s ENERGY A waste-to-resources to-resources company specializing in the deployment of a proprietary thermal destruction technology for the treatment of waste Plasma Arc Gasification via Graphite Electrodes through the power of PLASMA 2013 Gasification Technologies Conference Colorado Springs, Colorado October 15,

2 PEAT & PTDR Overview Technology: Plasma Thermal Destruction & Recovery ( PTDR ) Single stage plasma thermal process with Pyrolysis & gasification at ~1, C Graphite Electrodes (smaller systems) and AC torches (larger systems) End stage solution (no secondary by products) Minimal, if any, sorting required (organic and inorganic mixed) 21 patents issued/11 pending based on 7 separate IP matters (all owned by PEAT) Business: 4 marketed systems: (60 kg/hr, 125 kg/hr, 350 kg/hr & 1,500 kg/hr) Targets: hazardous, medical, industrial, refinery and pharmaceutical waste streams Smaller two systems designed for on site treatment, larger ones support BOO Locations & Regulatory approvals Sacramento (60 kg/hr), Taiwan (60 kg/hr & 250 kg/hr), China (60 kg/hr) Approvals received in: Taiwan, India, China, Alabama, California, Michigan, Indiana 2
