It’s important to always seperate heavy waste such as tiles, concrete and brick. Why? If you mix light waste say 3+ CM3 (which doesn’t weight a lot) then you add just 1 CM3 of concrete, you just added approx 1 ton to your general waste. Learn more about waste type here.
General waste is charged by tonnage and volume, so your weight now is very high and so now are your costs. Separated waste and separated concrete done as seperate jobs would save you plenty.
So always try and avoid your job looking like this one below.
