“If nothing changes quickly, global household waste generation will increase by 70% by 2050, driven by urbanization and population growth,” warns the World Bank in the report “What a Waste 2.0: A Global Snapshot of Solid Waste Management to 2050”. Rich countries generate more than a third of the planet’s waste – even though they represent only 16% of the population – with China and the United States in the lead. Thirty years ago, the appearance of huge slicks of plastic floating on the surface of the oceans shocked public opinion. Today, awareness is reflected in various measures aimed at developing sorting at source, composting, reuse and overall reduction of waste. The implementation of these objectives renews the waste treatment facilities at all levels of the territory, with an architecture that opens onto the city and participates in involving the citizens.
