Engineering a plastic-free future, one sip at a time.
EcoRyn was founded with a singular idea — that our daily disposables shouldn't leak microplastics, deforest the planet, or poison soil. By turning India's abundant banana agricultural waste into beautiful, functional teacups, we close the loop on both health and sustainability.
The problem with modern disposables
Most commercial paper cups are lined with polyethylene to prevent leaking. When hot beverages are poured in, the lining degrades — releasing millions of microplastics and potentially hazardous chemical residues into your drink. Conventional kraft-pulping is chemical-intensive, produces toxic effluents, and drives global deforestation. We refused to accept that trade-off.

Every cup tells a story
Chemical-Free Production
No kraft pulping. No bleaching. No polyethylene lining. Just clean mechanical processing.
Zero Plastic
Not a single microgram of plastic in the cup, in the manufacturing, or in the waste stream.
Supports Local Farmers
We pay farmers for what they previously discarded — banana stems and post-harvest leaves.
Rooted in nature. Engineered for scale.
Behind every EcoRyn cup are real banana leaves harvested with care from local plantations across Tamil Nadu. We turn agricultural waste into world-class packaging — and put money back in farmers' pockets.
Built with the best
Strategically partnered with the pioneering Eco Green Unit, Coimbatore for specialized machinery fabrication and design scale-up — ensuring world-class precision punch-and-die compression for every cup we make.
