Perth, Western Australia - Ghems Revegetation Environmental

Located in the coal rich Tanjung District of Kalimantan, Adaro is the largest single open cut coal pit in Indonesia.

GHEMS through its fully owned foreign subsidiary PT GHEMS Enviro has provided services for several stages of mine site rehabilitation and are now up to Stage 10 involving a 2 year contract for the implementation of rehabilitation across an annual area of approximately 250 ha.

GHEMS' Role

We provide comprehensive revegetation contracting works addressing tasks across the board from new mine development to progressive mine closure.
Our services include:

• Revegetation
• Organic composting and mulch supply
• Quick surface protection (Hydromulching)
• Erosion and sediment control
• Green belt dam protection
• Training and development
• Development of agribusiness opportunities for the region

Key to our success is the selection of appropriate seeds and bioactive organic mulch material which is applied by hydro-mulching equipment across highly modified mine environments which are characterised by erosion prone and nutrient depleted soils.

Project management incorporates regular formal monitoring and reporting of the revegetation works.

Outcomes

Our innovative surface treatment operations have seen topsoil and subsoil requirements reduced without compromising quality and have seen rapid surface protection and revegetation of green belt catchments which help to arrested surface drainage, minimised turbidity in dams and rivers and increased water quality.

Constant improvements and innovation are outcomes that are benefiting both the client and technology held by the GHEMS group.

Relevant Components

PT GHEMS Enviro is a fully equipped and locally run contracting operation with appropriate management systems in place. It employs over twenty trained local personnel and indirectly employs many more locals in the manufacture and supply of materials.
