Hi-Green Carbon Limited announced that its wholly owned subsidiary, Samsara Recycling Private Limited, is set to resume operations on May 18, 2026. The development follows the completion of extensive repair and restoration work at the subsidiary's plant located in Kukadsar Village of Kachchh District, which had been shut down due to a fire incident.

The company has successfully reinstated all affected machinery, equipment, and building structures at the facility. In a significant regulatory update, the Gujarat Pollution Control Board has revoked the previous closure order issued in the wake of the incident. This revocation effectively permits the subsidiary to recommence regular manufacturing and operational activities.

Restoration and Regulatory Approval

The restoration process involved comprehensive repairs to the plant's infrastructure. Following these efforts, the subsidiary secured the necessary approval from the Gujarat Pollution Control Board to lift the operational ban.

The company confirmed that regular manufacturing activities will commence from the specified date. This marks a return to normalcy for the subsidiary's operations after the disruption caused by the fire incident reported in October 2025.
