This all depends on the type of rubbish you are going to put in the skip bin.
General Waste is typically anything involved with a “general cleanup around the house and section” that is neither liquid nor of a hazardous nature.
Use a Cleanfill / Hardfill skip bin, if you have any of the following:
Concrete, clay, rocks, rubble, bricks, asphalt, ceramic tiles.
Use a Green Waste skip bin, if you have any of the following:
Grass, leaves, tree trimmings, small branches and other organic materials.
Only use a Soil / Dirt skip bin, if you have 100% pure soil / dirt (no turf or contaminants).
No other waste can be mixed in this bin, additional charges will apply if other waste is placed in this bin.
