Proper solid waste management remains a significant global problem. The heterogeneous nature of waste, including plastics, food scraps, paper, and glass, complicates the handling process.
In many cities, increasing waste quantities strain municipal authorities' capacity to keep up. Nairobi, "the Green City in the Sun," is not spared. This metropolis of 5.5 million residents generates between 2,000 and 2,500 tons of waste daily, with a large portion going uncollected.
