"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.
Just purchased an Extech EC500 pH/Conductivity/TDS/Salinity/Temp meter (148 Euro from Conrad.de) to bring to Kenya and Tanzania and Rwanda for our trainings. Wish I was able to purchase from the U.S. as it would have been about 40 dollars cheaper and could stretch the budget farther; but living in Europe we DO have better health care so there are some advantages... :)
