Comments Off on Kenyan activists are using human poop to make affordable cooking fuel

Resources are scarce in Kenya, and nearly half of the population lives below the poverty line , but they do have poop. Activists with Nakuru Water and Sanitation Services Company are providing clean fuel for local residents in the form of small balls of human feces. The group takes in truckloads of sewage from septic systems and pit latrines and transforms the waste into safe, economical briquettes that burn cleaner and longer than coal. And don’t worry: they are odor-free. Ordinarily, human feces can pose various health problems if left untreated or if disposed of improperly. Sometimes, it can even lead to cholera outbreaks or other sanitation -related diseases. However, because it is the most abundant and widely available human resource, Nakuru Water and Sanitation Services Company developed a method to turn it into an affordable, clean-burning fuel. To create the briquettes, the company slowly sun-dries the feces. Then, it treats it at a high temperature of 300 Celsius (572 Fahrenheit) in a kiln via a carbonizing process where sawdust is added to it. TreeHugger reports that the resulting product is then mixed with a small amount of molasses to act as a binder. It is then rolled into balls and dried. One kilo of the briquettes is said to cost just 50 cents USD — a very reasonable price for Kenyan citizens. John Irungu, the site manager at Nakuru Water and Sanitation Services Company, describes carbonization as “a process whereby we increase the carbon content of your materials.” He added, “In this case we are using the drum kiln whereby the sludge is fed, the drum has some holes at the bottom, these holes allow the oxygen to come in, in a controlled manner, that oxygen will only support combustion but to a certain level so that it doesn’t burn completely into ash. In this way, you are able to eliminate all the volatile matters, all the harmful gasses, and it is at this point that you ensure that your sludge doesn’t smell it is safe for handling when you are carrying out the other processes which is milling and briquette production.” Related: First-ever dog poop composting program in NYC comes to Brooklyn park It took some time to overcome the stigma that surrounds the use of human feces, but the company succeeded by informing residents that they could obtain a cleaner-burning cooking fuel for a fraction of the cost.

Posted by Al Jazeera English on Saturday, July 15, 2017 Every month, Nakuru Water and Sanitation Services Company produces about two tons of the human waste briquettes. By the end of the year, the goal is to produce 10 tons per month. This will occur once additional de-watering and carbonization equipment is procured, as it will scale up and optimize the present production methods. The company is also invested in the construction of more than 6,000 toilets that can collect waste. Someday, the company will expand its offerings elsewhere in Kenya, Africa. + Nakuru Water and Sanitation Services Company Via TreeHugger Images via  Nakuru Water and Sanitation Services Company

Comments Off on RIP Tobias Wong

We are shocked and saddened to read the news over on Core77 that NY’s iconoclast product designer Tobias Wong passed away over the weekend at the age of 35. We were big fans of Tobi’s wit and willingness to break molds, and it is clear that Wong will be dearly missed. Tobias had been the charming enfant-terrible / provocateur of the NY design scene for years, never shying away from pushing buttons and challenging design conventions.
