A different look at the recycling of plastics and the communities that support it


Global Challenge

The damage to our environment due to plastic waste is immense. For the most part, plastic waste is either dumped in oceans or buried in landfills due to its non-biodegradable nature.

Right now an estimated 12.7 million tonnes of plastic – everything from plastic bottles and bags to microbeads – end up in our oceans each year.
That’s a truck load of rubbish a minute.
Millions of tons of waste plastic from British businesses and homes may be ending up in landfill sites across the world.

Recycling Problem

The perceived solution, the repititive recycling of plastics, is not the answer. There is a huge carbon footprint associated with recycling. Heavily relying on cyclic recycling to solve plastic waste perpetuates the single-use culture, downgrades the material, and if often used to supplement virgin plastic.

Repetitive recycling generates a huge carbon footprint


Breaking the vicious cycle of repetitve recycling of plastic, we identified the opportunity to create durable, longer lasting products that utilise the seemingly negative properties of plastic to its advantage.

Target Community

Looking at the critical areas of plastic waste accumulation, we focused on the slum community of Dharavi in Mumbai, India. They not only deal with all the waste from the city, but they also have an established recycling industry. However, they currently only convert waste into industrial raw material or low-cost plastic consumer goods. Additionally, there is a pressing need for durable housing; which is conventionally constructed with materials and methods that are not lasting and suitable for the environment.

Plastic Recycling

The recycling industry in Dharavi is a £700m industry

80% of Mumbai’s solid waste is recycled; that is close to 8000 metric tons

Plastic waste is bought by the kilogram at (approx.) 15p per kg of plastic bottles

The plastic recycling industry employs close to 10,000 people

20,000 single-room factories support the economy of the slum


Housing Infrastructure

1 million people live in Dharavi with a population density of 869,565 people per square mile

Housing relies on materials like corrugated sheets, bamboo or wooden planks

Dharavi receives heavy monsoon rains, which takes its toll on poorly built houses

Most structures are built through manual labour due to narrow streets.


User Needs & Stakeholders

Creating a market demand for durable products from local communities will help provide additional sources on income. Durable housing protects against extreme climate conditions improving living habitats. Addressing excessive waste accumulation through small businesses with existing recycling facilities.

The Mission

How might we turn plastic waste into durable products to make a positive impact in a slum community and on the environment?


Through team brainstorming, we explored ideas ranging from improving green spaces to creating multi-purpose recycled plastic objects that are durable and long-lasting.

Open Source Process

We proposed PLOC as a way of making durable plastic bricks by integrating into the recycling system within Dharavi. The process utilises the network, resources and facilities currently active in the community. It is a model that can be applicable to similar communities like Dharavi as well.
