Ultrabasic forest rehabilitation

The company strengthens its role in sustainable mining by rehabilitating ultrabasic forests. Since 2003, the company has run a conservation and rehabilitation programme that includes the establishment of arboreta such as Taman Kehati Sawerigading Wallacea and the Himalaya Arboretum on post-mining land.

Reforestation of post-mining land

As of July 2024, PT Vale has reforested 3,817 hectares of post-mining areas, introducing over 67 species and improving biodiversity indices to a range of 2.06 to 2.39. More than two million local, endemic, and protected plants have been cultivated.

Waste separation programme

The initiative introduces a distributed bucket system for household-level waste separation, enabling organic waste to be processed in biodigesters with a capacity of 100 kilograms per day. This process generates methane gas as a substitute for liquefied petroleum gas (LPG) and produces approximately 23,760 litres of liquid fertiliser annually.
