The Kerala Minerals and Metals Limited (KMML) has achieved a significant milestone in environmental restoration by successfully converting land previously used for mineral mining into productive organic farms.

Under Haritham ee Theeram project, the company’s Mineral Separation unit has proven that biological rejuvenation of mined-out areas is not only possible but highly sustainable. Launched in 2022, the initiative has rapidly evolved from a land recovery experiment into a thriving agricultural hub, demonstrating the KMML’s commitment to ecological balance alongside industrial growth. “The complete removal of nutrient-rich topsoil had left the area devoid of essential minerals. We implemented a rigorous soil rejuvenation process as the first step. Using organic manure including cow dung, the soil’s natural fertility was restored,” says T. Karthikeyan, head of the department, Mineral Separation unit.

Cultivation of sesame

A standout success in this rejuvenation journey is the experimental cultivation of sesame, which is ready for harvest. The project specifically utilised Thilarani, a premium variety of sesame perfectly suited for the soil conditions of the Onattukara region. This variety is known for its deep brown seeds that mature within a span of 80 to 85 days. Thilarani is prized for its uniform capsule production and high seed density, making it a lucrative choice for farmers.

Notably, in December 2022, Thilarani—along with other local varieties like Kayamkulam-1, Tilak, and Tilathara—received the Geographical Indication (GI) tag, recognising its unique quality and regional significance. Rich in Vitamin E and antioxidants, the success of this crop marks a new chapter in utilising coastal soil effectively.

Beyond sesame, the project has turned the landscape into a diverse orchard. Visitors to the site can now see thriving groves of mango, chikoo, guava, and water apple trees, all of which are already bearing fruit. The area is also home to flourishing Punna trees and various vegetable patches that contribute to the local ecosystem. These efforts are being integrated with the Punarjani Pachathuruthu scheme, executed in coordination with the Haritha Keralam Mission.

Productive plantations

By creating these mini-forests and productive plantations, the KMML is not just restoring the earth but is also setting a benchmark for public sector undertakings on how to balance industrial extraction with proactive environmental healing, ensuring that the coast remains green for generations to come.

“The ultimate objective of this ecological mission is to transform the once-desolate, mined-out areas into lush, green belts before returning the land to the community. Projections suggest that through these intensive organic interventions, a complete environmental recovery is achievable within a short span of three to four years,” says Mr. Karthikeyan.
