"Zabaleen" is the Arabic term for those visionary and enterprising people whose culture revolves around recycling. The Zabaleen are experts at "transforming one man's garbage into another man's gold" and aspire toward a net zero-waste economy. Applied and supported this could lead to true energy independence, not only by radically reducing our demand for "raw materials" and hard to extract natural resources but by recycling other less obvious phenomena and materials that are now wasted.

Welding oil drums to make a biogas digestor
Our Masai mechanic friend Stephen taught Hanna and me how to arc weld today so that we could create a different kind of biodigester today more suited to local materials and the budget of the Masai (average salary for those employed in tourism is 13 dollars a day). Turns out plastic tanks are prohibitively expensive but discarded oil drums are everywhere. The trick is welding them together to be gas-tight, and it ain't easy!
