The Indian Institute of Technology (IIT Roorkee) and YB Scientific R&D Solutions have collaborated to create a technology for recycling trash polyethylene packs into paver blocks and wall tiles. Processes may be an interesting choice for waste producers to manage plastic wastes following the Plastic Waste Management (Amendment) Rules 2021.
- A technology for producing cement-free paver blocks and wall tiles from waste HDPE, milk and oil packages has been devised by IIT Roorkee and YB Scientific R&D Solutions.
- According to the Plastic Garbage Management (Amendment) Rules 2021, the institute’s PRAYASPR program can help waste producers manage plastic waste.
- It has superior interlocking, aesthetics, and light times.
- The institute claims they are unbreakable and resellable.
- The tiles will be cheaper than paver blocks, costing roughly Rs 14 per square foot.
- IIT Roorkee and YB Scientific R&D Solutions came up with a way to make cement-free paver blocks and wall tiles out of waste polyethylene packets, milk packets, and oil packets. According to the institute, it’s called PRAYASPR, and it could be a good way to deal with plastic waste by the people who make it.
It’s not just that these products are better at the interlocking, but they also have longer light times. The institute said they aren’t going to break and have a fair value when they’re sold. An IIT Roorkee professor says the technology recycles old polyethylene packets to make cement-free paver blocks. This is a more environmentally-friendly way to make the pavers, Prof. Prasenjit Mondal says. Before they can be made into blocks, the plastic packets must be shredded into small pieces. Then, they’re mixed with other ingredients to make the plastic soften even more. Finally, they’re put into a hydraulic press to be made into blocks.
Eco-friendly: “They can be used in places like building premises and monuments,” Mondal said. They can also be used in landscapes, public gardens and parks, drives, paths, and floor tiles, among other things, he said. For each paver block, about 250 g of waste plastic is used. To cover a 1 sq ft area, about 1.5 kg of waste plastic will be needed. Rs 8–9 is the cost of making each piece.
Paver blocks will be more expensive, but tiles will be cheaper because they will only cost about Rs 14 per square foot to make, it said. The team members were Prasenjit Mondal, Hemant Goyal, and Navneeta Lal, all from the Department of Chemical Engineering at IIT Roorkee. Yash Dua, from YB Scientific R & D Solution, was also on the team.
A company called YB Scientific R & D Solution in Roorkee, Ramnagar, said that India’s amount of plastic waste grew by more than 21% each year in the years 2019–20. This is why they need PRAYASPR. This plastic waste also has low-density polyethylene (LDPE), closing sewer lines. In addition, in India, waste plastics litter the landscape because there aren’t enough ways to dispose of them properly. This has negative effects on the environment. To deal with waste plastics in a more sustainable way, a project called PRAYASPR has been set up by IIT Roorkee.
