Recompose Recycling Private Limited, a Coimbatore-based waste management and recycling company, has launched a water hyacinth mulching Coimbatore trial project to convert the invasive weed into mulching material. The company partnered with WWF-India and Noyyalaaru Trust to conduct the trial at Sulur Big Tank on Saturday, August 8, 2026, shredding the weed using a dedicated machine. If successful, the process could also yield other value-added products from a plant long treated as a nuisance rather than a resource.
Why water hyacinth is a problem in Coimbatore’s water bodies
Water hyacinth spreads fast. A single plant can double its coverage in under two weeks under the right conditions, and once it takes hold, it forms thick floating mats across ponds, lakes and canals. These mats block sunlight from reaching the water below, starve aquatic life of oxygen, and choke irrigation channels and drainage paths. Sulur Big Tank, like many water bodies around Coimbatore, sits close to residential and agricultural land, so an unchecked spread creates both an ecological and a civic maintenance burden.
Removing the weed manually is labour-intensive and rarely permanent, since the plant regrows quickly from fragments left behind. That is part of why turning the removed biomass into something useful, rather than simply discarding it, has become an attractive alternative for waste management companies.
How the mulching trial works
As part of this water hyacinth mulching Coimbatore initiative, Recompose Recycling Private Limited is shredding harvested water hyacinth using a dedicated machine to break the plant down into a fibrous, mulch-ready material. The trial at Sulur Big Tank marks the initiative’s first public run, carried out in partnership with WWF-India and Noyyalaaru Trust. Mulch made this way can be spread over soil to retain moisture, suppress weed growth, and slowly add organic matter as it decomposes. This use case has already shown promise in agricultural studies on crops like turmeric, where water hyacinth mulch improved plant growth compared to no mulching at all.
Beyond mulch, the company is also exploring other value-added products from the same raw material, though specifics on what these products are have not yet been made public.
What Makes This Water Hyacinth Mulching Coimbatore Trial Significant
This water hyacinth mulching Coimbatore effort stands apart because most water hyacinth removal in Indian cities ends with the plant dumped or left to rot, offering no return on the labour and cost of clearing it. A shredding-and-mulching model changes that equation. It turns a recurring civic expense into an input for agriculture and, if the additional products pan out, potentially into a modest revenue stream. The involvement of WWF-India and Noyyalaaru Trust also signals environmental-sector backing behind the initiative, not just a standalone commercial experiment. For farmers and home gardeners in and around Coimbatore, a locally sourced mulch option could mean lower dependence on materials trucked in from farther away.
What’s still unclear
As this is an early-stage trial, several details remain unconfirmed:
- The exact scale of the trial and whether it will expand beyond Sulur Big Tank to other water bodies
- The specific value-added products Recompose Recycling is exploring beyond mulch
- A timeline for when the mulching material might become commercially available
- Whether Coimbatore Corporation or another civic body will support or help scale the initiative
Todays Coimbatore will continue tracking this water hyacinth mulching Coimbatore initiative and update this article as more details become available.
Frequently Asked Questions
Which company is converting water hyacinth into mulch in Coimbatore?
Recompose Recycling Private Limited, a Coimbatore-based waste management and recycling company, is running the trial, in partnership with WWF-India and Noyyalaaru Trust.
Where did the trial take place?
The trial was conducted at Sulur Big Tank, near Coimbatore, on Saturday, August 8, 2026.
Why is water hyacinth considered an invasive weed?
It spreads rapidly, forms dense mats on the surface of water bodies, blocks sunlight and oxygen from reaching aquatic life below, and can clog irrigation channels and drainage systems.
Is water hyacinth mulch actually useful for plants?
Yes. Studies on crops such as turmeric have shown water hyacinth mulch can improve soil moisture retention and support plant growth compared to leaving soil unmulched.
What other products is Recompose Recycling exploring from water hyacinth?
This has not yet been publicly disclosed beyond mulching material. Todays Coimbatore will update this section once further details are announced.
