Town of Hague Landfill Reclamation Study. Researching Ways to Increase WasteHeating Value and Reduce Waste Volume

摘要

This research project examined the use of monitored composting to reduce theamount of waste requiring disposal from a landfill reclamation project, and to provide an improved, higher Btu fuel for waste-to-energy combustion. Landfilled municipal solid waste from the ongoing Town of Hague landfill reclamation project was excavated, screened and placed in static piles (windrows) on top of the landfill footprint. Approximately 500 cubic yards of screened reclaimed waste, originally landfilled in 1990, was arranged into a single long windrow of varying depths and moisture content. The internal temperature of the compost windrow was monitored twice each week, and no odor, vector leachate problems were experienced. Two months after and again 4 months after the windrow was established, waste was re-screened the net volume and weight reductions determined each time. The recovered compost soil was subjected to analytical testing to determine its suitability to remain as backfill at the reclaimed landfill site. The resulting waste product after both re-screenings was sent to a waste-to-energy facility for combustion testing.
