Can we shift waste to value through 3D printing in Tanzania?
This post is an excerpt from a blog post shared on the World Bank IC4D Blog. Read it here.
Plastic waste, in particular PET, which is typically found in soda bottles, is becoming abundant in African cities. In Dar es Salaam, one of the most rapidly urbanizing cities in Africa, BORDA found that about 400 tons of plastic waste per day remains uncollected or unrecycled. Although about 98 percent of the solid waste generated per day can be recycled or composted, 90 percent is disposed in dumpsites.
At the same time, the recycling industry has started to grow because of new initiatives, community organizations and private companies. There are a few organizations that repurpose waste into arts and crafts, tools or apply it as a source of energy – such as WasteDar. However, the majority collect or purchase plastic waste from collectors, primarily with a view to export, rather than recycle or reuse locally.
Socially and environmentally, waste management is one of the biggest challenges for an increasingly urbanized world. Waste pickers can earn as little as US$1-2 a day in dangerous conditions with little opportunity for advancement. They make up some of the most disadvantaged communities living in deep poverty.
Through a new market for sorted waste materials, these communities may access higher income generation opportunities in a sustainable manner. This presents an opportunity to explore turning this waste into value more close to home.
