The city of Biddeford is set to become the latest community in southern Maine to try to boost its recycling rates with a new trash disposal system. The system gives residents a large 65-gallon bin for recyclables and a smaller, 35-gallon bin for trash. If a resident generates more trash that can fit into the bin, he or she must buy city trash bags from local stores. The incentive to throw away less trash aims to get Biddeford’s 10 percent recycling rate closer to the state average of 40 percent. The public works director says the city will save about $55 per ton of trash it doesn’t have to pay to dispose, The new system starts Monday. The Portland Press Herald reports, that Biddeford joins about 100 communities statewide with similar programs.
