At the Montgomery County, Maryland, Transfer Station, conveyor belts speed past workers
On any given day, 8 percent to 30 percent of recyclables are contaminated or recycled improperly (i.e., there is food residue in containers or items not eligible for recycling are mixed in among plastic water bottles). As a result, all those items you intended for recycling may very well end up in a landfill or the incinerator.
Montgomery County hopes to reach a 70% recycle rate by 2020, which will require raising the public’s awareness of recycling practices and policies. Until then, the county has one broad rule of thumb: when in doubt, keep it out.
