Plasma Resource Recovery System

Based on the expertise and experience gained in waste gasification and vitrification, PyroGenesis has developed the efficient 2 stage Plasma Resource Recovery System (PRRS) designed to uniquely treat a broad range of wastes, including industrial, hazardous and clinical wastes. Depending on the size and the composition of the waste stream, PRRS has the potential to be a net energy producer generating enough energy to not only operate the system but producing an excess which could be sold back to the grid. PRRS is scalable, fully automated and is targeted at processing between 0.5 to 100 TPD of waste (equivalent to approximately 150 to 30,000 tonnes per year). PRRS is significantly smaller when compared to similar capacity incinerators, produces no ash or dioxins and is a cost competitive alternative to conventional alternatives.

PRRS consists of four main processes: waste pre-treatment and feeding, plasma thermal treatment, synthesis gas cleaning and energy recovery.

Waste does not need to be pre-sorted and can be introduced into the PRRS graphite arc furnace in virtually any form (shredded material, sealed containers, liquids, sludges).

PRRS uses a graphite arc plasma furnace followed by a plasma-fired eductor to convert the organic fraction of waste into a soot-free synthesis gas (containing mostly carbon monoxide and hydrogen) and the inorganic fraction into a stable, inert slag which is a glass-like material that can be used as a construction material as well as a metal which can be recovered as an ingot.

The synthesis gas cleaning system is designed to remove any acid gases and capture any trace amounts of particulates or volatile heavy metals. The cleaned synthesis gas can then be used as a fuel in a boiler, an internal combustion gas engine or a gas turbine for the production of electricity, steam, and/or hot water.
