The post is a bit old, but I still have a question for understanding: 480€ for 25 tons of "trash" seems quite cheap to me. I paid 240€ just for 5 cubic meters of mineral construction waste.
It was 10 tons of sand. A friend took it for her horse's paddock. We were able to dispose of the wood for free at our recycling center. Concrete costs 13 euros per ton at our local disposer. Lightweight construction materials (aerated concrete or pumice) cost, I think, 130 euros per ton. I checked where glass wool was cheapest and paid 90 euros for 2 cubic meters of glass wool. You have to separate a lot and look for the cheapest options. It takes a lot of time but also saves a lot of money. If I had taken mixed containers, I would have easily been 5,000 euros poorer.
