WTP’s waste treatment systems integrate specialized, highly efficient anaerobic digestion processes and machinery utilized in the waste management industry to 1) remove the high-value recyclables for resale and 2) process the remaining solid waste fraction into a valuable renewable energy feedstock (typically, biogas and electricity) or beneficially used as a soil amendment or for daily cover at the landfill. With the targeted recyclables removed from the waste stream and post-digestion, the volume of the remaining waste material going to the landfill is dramatically reduced and stabilized—typically 5% or fewer waste by-products returned to landfill as inert material.
The demands of processing complex feedstocks doesn’t afford the luxury to engineer, design and manufacture one piece of equipment to handle the task. Feedstocks such as MSW have multiple densities and moisture levels—everything from cardboard and green waste, to food waste and other organic material, to metals and plastics. (Metals are removed before the digestion stage begins.) The WTP process integrates state-of-the-science, field-proven OEM process equipment to meet the requirements of the client’s waste stream.
The general conversion process, depending on the waste stream:
