The oven has a superheated steel plate inside an incinerator box to vaporize drops of water. The oxygen released then helps burn discarded "sump" oil from vehicles – a pollutant in the slums – pushing up the temperature. The target is for the cooker to consume half a ton of waste every day once it has finished trials in about a month.
The project is the first of its kind, according to the United Nations Environment Programme (UNEP), which provided $10,000 for the launch.
"We have already seen a difference in the area we are targeting," says Pauline Nyota, of the Umande Trust, a group that works in slums to improve sanitation and leads the project. "The drainage ditches are much cleaner – just wastewater when before they were clogged with rubbish." Photo credit: Christian Science Monitor ::Via The Christian Science Monitor
