The city of Ambikapur in India’s Chhattisgarh state is launching a “garbage cafe” where anyone can eat healthy meals in exchange for collecting trash. The cafe will be centrally located in the city’s busiest bus terminal and is owned by the Municipal Corporation. Although such cafes exist in other cities around the world, the plastic trash collected for Ambikapur’s cafe is unique, because it will go directly into asphalt to pave the city’s roads.

The practice of melting plastic and incorporating it into paving materials is not new in India. In fact, the government mandated that all urban areas utilize plastic waste in their roads in 2015, but most have yet to follow orders. The city of Ambikapur has one such road so far, and there are an estimated 100,000 kilometers of plastic roads throughout India.

The innovative chemical process is led by professor Rajagopalan Vasudevan, but it has also been replicated and modified by engineers around the world, including the plastic-producing giant Dow Chemical.

“At the end of the day, plastic is a great product. It lasts for long, which is a problem if it’s a waste product, but not a problem if we want it to last,” said engineer Toby McCartney, whose company produces recycled plastic pellets that are mixed into roads.

According to McCartney, plastic roads last three times longer than conventional roads and need less maintenance. They are more resistant to flooding and less likely to get potholes. McCartney also promises his prototype does not break down into microplastics or enter ecosystems.

With an initial budget of just about $7,000 USD, the cafe is a triple-win for the government’s goals to address food insecurity, clean up the roads and improve infrastructure.
