Waste, Materials & Circularity

The problem

The economy takes in far more materials than it returns. Products are designed for short use, and the materials inside are lost after disposal.

Who may be affected

Communities near landfills and informal recycling sites, and consumers who cannot repair what they buy.

6.9%

of materials entering the global economy came from recycled or secondary sources

62 Mt

of electronic waste in 2022, of which only 22% was formally recycled
