pay to throw
v. phr.— «The most successful curbside programs give residents who recycle a reward—lower garbage rates. With three garbage cans, for example, you pay full fare. With one can of trash and one of recycling, you pay less. Both city renewable resources manager Kevin Harun and Alaska Waste CEO Jeff Riley agree that type of system works best. There’s even a name for it: “pay to throw.”» —“Get green” Anchorage Daily News (Alaska) Feb. 15, 2008. (source: Double-Tongued Dictionary)
