Every year, especially at the end of a financial year, you measure the Compound Annual Growth Rate (CAGR) of your assets and investments. You take stock of the money you made, your expenses and your savings. But have you wondered about the amount of plastic you used?
India’s Towering Plastic Waste, Problem or Potential?In this age of getting everything packaged and getting them in an instant, plastic waste has increased. From 14 MT in 2016-17 to 20 MT in 2019-20. That’s a CAGR of 9.7%. Our plastic waste is growing 5 times faster than the Indian economy’s CAGR.
“Though every plastic product has a market price, the real cost is borne when it forms a mountainous landfill.” – Innovation in Plastics, The Potential and Possibilities Starting tomorrow morning, count the number of plastic waste you throw into the dustbin till the night. You’ll be shocked with the number. Mine was 14. From the milk packet to my new scissors’s packaging. And this is just mine, not my entire household’s. 70% of all this plastic waste ends up in landfill and aquatic dumps. The UN says there will be more plastic than fish in the world’s oceans by 2050. The way to un-do the plastic mess will need changes across the entire supply chain. From plastic production to consumption and disposal. The Indian Plastic Market also needs to meet circularity. Circularity is about using, resuing, repairing and recycling instead of landfilling. This way, the generation rate will come down. And we can extract maximum value out of what’s already generated. Surat, the 2nd cleanest city after Indore is an excellent example to follow. The Surat Municipal Corporation makes money from plastic waste.
Muck to Money: How Surat Earns From Plastic WasteSurat generates around 150 metric tonnes of plastic waste everyday. 50% of this goes straight to Eco-Vision’s plastic waste management facility in the city. Here’s what they do with it.
The Surat Municipal Corporation collects and brings plastic waste here.
All the visible dust particles are then removed.
The plastic waste is sorted according to type and colour.
Before the plastic is shredded, it’s pre-washed.
The plastic waste is cut into tiny pieces.
The pieces are washed again to remove sticky waste.
Plastic waste is dried to remove water and moisture.
The agglomerator converts it into small dense cubes for the extruder.
The extrusion machine converts plastic waste into usable pellets.
Plastic pellets are bought by furniture makers, pipe manufacturers, tarpaulin makers etc.
Watch the full video here. For every kg of plastic pellets, Eco-Vision and SMC make Rs.15-50. Plastic waste is reused and landfill space is saved while making money. Isn’t that a win-win?
Plastic-to-Fuel Technology: Another Way to Use Plastic WastePTF technologies address the environmental challenges and make plastic waste into valuable energy resources. There are many plastic-to-fuel technologies.
- Pyrolysis heats plastic waste with no oxygen present to convert it into liquid or gaseous products.
- Depolymerization breaks down the polymers in plastic into smaller molecules.
- Gasification convers plastic waste into syngas which can be used as a fuel.
