What will my load cost here?

Weight assumptions
  • Household trash, loose: 275 lb per cubic yard (EPA lists 250–300 for uncompacted mixed residential waste).
  • Yard waste, loose: 250 lb per cubic yard (EPA: mixed yard waste, uncompacted).
  • Construction debris, mixed: 484 lb per cubic yard (EPA: C&D bulk).
  • Concrete, broken: 860 lb per cubic yard (EPA 2016 table; older EPA tables list loose scrap concrete as heavy as 1,855, so real loads may weigh much more).
  • Volumes are geometry, not data: a full-size pickup bed filled level with the sides is about 2 cubic yards (roughly 6.5 ft × 5 ft × 1.7 ft); a 6×10 ft utility trailer filled 2 ft deep is about 4.4 cubic yards; a 33-gallon trash bag is about 0.16 cubic yards.

Weight factors: U.S. EPA, Volume-to-Weight Conversion Factors (April 2016). Real loads vary a lot; the scale at the gate decides.
