Whether it’s for parties, school projects, or packaging needs, thermocol has been widely used for its availability and lightweight property. But amid its widespread applications, users tend to overlook the harmful effects caused by it. Composed of polystyrene, thermocol becomes non-biodegradable and produces harmful air pollutants when exposed to sunlight.

Kanpur’s Chaitanya Dubey found a unique biodegradable alternative to traditional thermocol using mushroom mycelium and agricultural waste.

Monish Siripurapu has created ‘CoolAnt’, a natural cooler that uses the design of beehives to reduce room temperature during summer.

Chaitanya says his eco-friendly solution is lighter and sturdier, and has the same feel as the polystyrene. “In terms of strength, it compares favourably to high-density thermocol; however, weight-wise, it leans a bit on the heavier side,” he adds.

Talking about the elements used to create the alternative, he explains, “Mycelium, or the roots of the mushroom, serves as a natural adhesive. Additionally, we utilise a combination of agricultural waste and natural fibres, contributing to the durability and longevity of the thermocol. The inherent properties of mushrooms make for a robust material.”

This biodegradable thermocol also doubles up as a fertiliser and decomposes in 60-90 days. “Once its purpose is fulfilled, just crush it and add it to your plant pots; it will act as a natural fertiliser,” he shares adding that the product is now accessible to packaging businesses.

It was while pursuing a small business course that Chaitanya got interested in mushroom farming and discovered its potential. With guidance from IIT Kanpur, he launched his startup ‘Kinoko Biotech’ to make bio-materials from mushrooms.
