192 ksh / KG pf plastics converted to fuel

from another references

1 gallon of fuel from 8.3 pounds of plastic [1] ~ 420 gallons from 3286 lb of plastic

There is a need to evaluate the impacts of the current waste stream practices and provide a data-driven solid waste management plan for the improvement of human health, the environment, and the economy of Machakos, Kenya.  - garbagemap.org

Machakos is littered with many waste piles on the roadside, where fire and livestock grazing have become the de-facto course of action in attending to them.
