Entrepreneur who makes building materials from waste. Standard Digital, January 27, 2017.
Dr Aghan Oscar displays one of the tiles made at his factory using waste plastics.
With the high prices of steel, vandalism of metals and rotting of timber, experts in the built environment are coming up with alternative building technologies that are cheap, durable and free from vandalism.
One such expert is Dr Aghan Oscar, who is recycling waste plastic into building materials and selling them to developers who use them to provide affordable housing.
Dr Oscar produces the materials at his industry in Kariobangi South, Nairobi. Some of the products include lumber planks, paving slabs, manhole covers, ridge tiles, and fencing posts.
The company – Continental Renewable Energy Co Ltd (Corec) – was born in 2013. Dr Oscar has contracted Kariobangi youth to collect, clean, crush and sell scraps to the factory.
The fencing posts come in various sizes that sell for between Sh800 and Sh1,000 per post. He says they make about 100 posts per day and sell them to the Kenya National Highways Authority and individuals.

New York City Fights Scavengers Over a Treasure: Trash | Source: New York Times, Mar 20 2016 |
The video begins with ominous notes from a piano and an image of crime scene tape. The camera pans to men hunched over garbage pails, sifting for bottles, and a stoop-shouldered woman towing a shopping cart full of cans. Some might feel sympathy for these collectors, but the video makes clear that the New York City Sanitation Department, which made the video and posted it online, wanted them to be seen as something else: common criminals.
“Scavengers are putting the Department of Sanitation’s recycling program at risk, by removing the most valuable recyclables,” a voice-over begins. “Nobody wants to be perceived of as picking on the little guy, but the lone scavenger is now an organized, sophisticated mob of scavenger collectives that systematically removes valuable recyclables,” it continues. “Recycling is the law. Scavenging is a crime. Don’t allow scavenging to steal recycling’s future.”
The moment refuse hits the curb it becomes the city’s property — and the city’s problem. From there, materials like metals, cardboard and plastic are supposed to enter into the vast web of the recycling process, a network of carters and sorters, compactors and remelters. The theft of such items has long been an issue, taking a toll on the city’s curbside recycling, or diversion, rate. The problem has peaked and fallen over the years as prices for commodities have fluctuated.

Recycling is something in which we all have a role to play. It’s one of the easiest ways we can contribute to protecting our environment. When it comes to recycling at home, there often seems to be a mismatch between our good intentions and our actions and in many countries around the world, less than a third of us recycle at home.
How can we nudge people to incorporate better recycling habits into their daily routines at home? What tools, campaigns or services might we design to support habit changes that stick? Together with Coca-Cola Enterprises (CCE) – one of the world’s largest independent bottlers of Coca-Cola products – we’re asking the OpenIDEO community to help us find creative ways to encourage people to recycle at home.
UN: Treated Waste Could be ‘Gold Mine’ | Source: Environmental Leader – Oct 10 2013
Recycling and waste treatment can be a “gold mine,” perhaps literally, according to a UN report that finds treated waste can be put to profitable use.
For example, 1 metric ton of electrical and electronic wastecontains as much gold as 5 to 15 metric tons of typical gold ore, and amounts of copper, aluminum and rare metals that exceed by many times the levels found in typical ores. As a result, printed circuit boards are probably the “richest ore stream you’re ever going to find,” according to the Guidelines for National Waste Management Strategies: Moving from Challenges to Opportunities.
Many waste products can be reused and, if waste is separated at source, the uncontaminated organic fraction can be composted or digested anaerobically, the report says.
Issue 50 April 6, 2012 | Focus on the Informal Sector and Solid Waste Management
The informal waste sector provides a much needed service in the developing world; the work of this sector reduces waste in communities, increases the reclamation and reuse of materials, and helps to lower greenhouse gas emissions. This issue of the WASHplus Weekly contains recent reviews on the economics of the informal sector and the diseases and injuries that waste pickers endure. Also included are case studies from Bangladesh, Brazil, Pakistan, the Philippines, and recent videos.
