Deconstruction: Waste not, want not
Every year, in France alone, the building industry produces 46 million tonnes of waste, compared to 30 million tonnes from households. How should this waste be dealt with? And who should pay for it?
Most of the waste comes from the process of demolition. While the most profitable materials are recycled, large quantities of wood, plaster, carpet and glass cannot easily be reused - not to mention polluting waste such as asbestos, glue and paint. These materials often end up being dumped in nature. More than 100 unregulated sites have sprouted up across the Paris region, in a phenomenon that is both illegal and hard to control.
This week on Down to Earth, we look at how the industry can reduce and reuse the waste it generates.
