When people ask, “does old metal dryer vent go in trash or recycling?” It highlights how waste management and recycling are now part of daily conversations. On an industrial scale, the real challenge isn’t just sorting items—it’s finding the right equipment to recycle complex plastics efficiently. That’s where Kaivanya comes in. While we don’t build recycling plants ourselves, we manufacture the bimetallic screws and barrels that power them. Recognized among the reliable extrusion machine manufacturers in India and a trusted extrusion machine supplier in the USA, Kaivanya provides critical components that make recycling plants perform better, longer, and more efficiently.
The Role of Screws & Barrels in Recycling
Every extrusion system—from vented recycling plants to blown film plants—relies on the quality of its screws and barrels. These components are the heart of the machine, responsible for melting, mixing, and processing plastic waste into reusable granules. Without durable, high-performance screws and barrels, even the most advanced machines cannot deliver consistent results.
At Kaivanya, we specialize in bimetallic screw and barrel technology that withstands the toughest recycling challenges. Our products are designed to handle multilayer films, printed plastics, and moisture-laden waste—materials that are common in vented recycling processes.
