CHALLENGE: A large U.S. municipality approached Curry Industries with their problem: How do we capture the noxious odors, methane and ammonia gas emissions that are regularly given off by the compost our recycling programs collect? The compost reactors were twenty feet wide, ten feet deep and almost a half-mile long. Not only were they almost impossible to cover but whatever cover they did use had to be able to withstand corrosive elements.
CURRY INNOVATION: Based on their existing air-tight Poly-Fastener® system, the Curry team created a double-coated, polyethylene weave that when affixed with their Poly-Fastener System would allow for easy deployment in sealing not just a compost reactor, but any hole, inside or out, from 3 to 30 feet. The product can also handle large quantities of chicken litter or even control manure odors while allowing for the capture of methane gas for energy use.
RESULT: The resulting product has been found to improve compost quality and decrease metal corrosion in compost facilities while creating a more uniform temperature in the compost, accelerating the overall time involved in reaching prime use viability. The Bio-Retractable Compost Cover tends to be purchased by cities or counties which means current use hinges on specific environmental commitments from elected boards or councils, which are ever-changing.
