Editor's Notes
- Injured employees causes lost time, workers comp, more administrative work and a hesitancy to keep equipment clean
- Mattress do not compact well and leave air pockets for fires to start and spread Landfill Operations 101 is to get good compaction in part to eliminate air voids to reduce fire risk Mattress foam smolders, which sustains combustion at lower temperatures and longer periods of time as a catalyst to get other materials burning A cigarette or ember can burn into a mattress, be buried and cause a fire after buried Mattresses once they start burn can support alot of fire
- Mattress are buried flat against the landfill working face and because they do not compact well act as a leachate interceptor and drain
- Law requires 6 inches or equivalent daily cover. Soil rolls off a mattress, so more daily cover must be used -- more time money and landfill space is used
- To visualize how much space mattress consume consider: La Crosse County, population 118,000, according to two 1 month surveys that between 7,500 and 9,000 (~8,250) mattresses were being buried a year. A typical compacted mattress takes up 23 cubic feet of landfill space which doesn’t count wasted daily cover. This means the county used 189,750 cubic feet of landfill airspace for mattresses. This would be the equivalent of a football field stacked 4 feet high in mattresses. BTW, if a landfill wants to improve its overall compaction – stop buriyng mattresses
- One landfill operations staff measured the additional-time on average it took to manage mattresses to: not bury on an outside slope (side slope seeps); not bury at the end of a day (wastes daily cover); not bury in mass (landfill instability); and untangle equipment– they came up with 3+ minutes per mattress and most if this involved a worker and a piece of equipment. Using a labor and equipment rate of $100/hour equals and extra cost of $5/mattress. And this doesn’t count Workers Comp and fire issues. Neil Bolton, President of Blue Ridge Services and a National Landfill Operations Expert wrote in the March/April 2018 issue of MSW Management that a typical mattress in a $50/ton landfill consumes about $13 worth of air space. These two costs of airspace and operations equal $18 per mattress.
- Take a look at the peer reviewed Landfill Mattress Math document posted on the internet and found at www.7Rivers Recycling.com Figure out what yours sites true cost is to bury a mattress; start surcharging mattresses according to the real costs
- A mattress buried in a landfill increases GHG emissions by 137 Kg CO2E -- equal to burning 16 gallons of gasoline. A mattress recycled reduces GHG emissions by 62Kg CO2E -- equal to not burning 7 gallons of gasoline.
