A Coimbatore-based recycling firm has launched a pioneering trial to transform invasive water hyacinth into organic mulching material and other useful products.

Key Takeaways

  • Recompose Recycling Private Limited launched a trial to shred water hyacinth into mulch.
  • The initiative was conducted at Sulur Big Tank in collaboration with WWF-India and Noyyalaaru Trust.
  • The shredded material can significantly reduce irrigation costs for farmers and highway departments.
  • A single shredder can process 5 to 8 tonnes of hyacinth per day.

In a significant move toward sustainable waste management, a Coimbatore-based company specializing in recycling has initiated a trial project to convert the invasive water hyacinth into useful mulching material. The project aims to tackle the ecological threat posed by this plant while creating economic value.

The trial was conducted at the Sulur Big Tank on Saturday, August 8, 2026. The initiative was a collaborative effort between Recompose Recycling Private Limited, WWF-India, and the Noyyalaaru Trust, in the presence of Sulur MLA N.M. Sukumar.

Why This Matters

BozokMedia analysis shows that the conventional method of managing water hyacinth is economically draining. Currently, local bodies spend crores of rupees to excavate the plant and dump it on vacant lands, essentially turning a biological problem into a land-use problem. This new method shifts the paradigm from disposal to utilization.

According to C. Prashanth, founder of Recompose Recycling, the shredded hyacinth acts as an excellent mulching material, particularly for coconut farmers. By covering the soil, it helps retain moisture and reduces the frequency of irrigation. Furthermore, the Highways Department can utilize this material to maintain roadside plantations, reducing water expenses.

Transforming an invasive species into a commercial resource is the ultimate way to balance ecological restoration with economic sustainability.

The project is currently moving into the testing phase, with efforts underway to validate the shredded material's effectiveness at the Tamil Nadu Agricultural University. Future plans include producing briquettes from the plant to expand the product line.

Historical Background

Water hyacinth is one of the world's most invasive aquatic plants. It spreads rapidly across water bodies, blocking sunlight and depleting oxygen levels, which leads to the death of fish and other aquatic life. For years, management has been limited to expensive mechanical removal without any secondary utility.

Did You Know?: Water hyacinth can double its population in as little as two weeks under ideal conditions, making it a massive threat to water security.

Frequently Asked Questions

1. How does shredded water hyacinth help farmers?
It serves as mulch that retains soil moisture, thereby reducing the amount of water needed for irrigation and eventually turning into organic manure.

2. What is the capacity of the shredding machines used?
A single shredder machine is capable of processing approximately five to eight tonnes of water hyacinth every day.
