The Global Trash Challenge: Managing Waste in a Growing World

TLDREvery year, the world generates over 2 billion tonnes of trash. A third of the world's waste is openly dumped or burned, causing environmental and health concerns. The amount of rubbish generated is expected to increase to 3.4 billion tonnes by 2050. Waste management involves collection, treatment, and disposal of waste, with solid waste coming from various sources. Singapore has implemented sustainable waste management practices, including incineration and recycling. Semakau Landfill is Singapore's only landfill, and efforts are being made to extend its lifespan. Waste-to-energy plants are used to convert waste into electricity. Reduction of waste and increased recycling rates are crucial for a sustainable future.
