I reuse everything from remodels. Seems a shame to throw out always. And other skips are getting bought by others to use in their building projects.
When we need fill in the US, a big truck comes and dumps actual soil and rock so that lead and other things don’t leach into the groundwater, the construction waste is landfilled after removing the metal for recycling.
If you have well water and have been using construction demolition waste nearby your wellhead, I would suggest an RO filter for drinking water, yikes.
