List ordinary project debris
Identify the material rather than writing only “mixed waste”. Drywall, wood offcuts, old carpet, cabinets, and household goods each describe a different load. Ask which can be loaded together.
Flag dense material
Mention concrete, brick, asphalt, tile, shingles, and soil separately. If you can, include an approximate quantity so the load can be planned for both weight and volume.
Set aside items that may need separate disposal
Check before loading batteries, paint, solvents, fuel, pressurized cylinders, tires, electronics, or appliances. If you suspect asbestos, leave the material undisturbed and consult a qualified professional before removal.
