Promoting saving the nature

KBN Group intends to maximising the positive impact on the environment in the area of operations, measure the negative impacts, as well as taken efforts to mitigate and reduce those negative impacts; effluent to water, emission to air, and contamination to land. Our subsidiaries APT and GPB, especially those engaging in coal mining and processing, manage the environment by minimize the impact or effect of their operational activities on the environment. In line with the KBN Group vision and mission and prevailing regulatory provision, any mining activity shall involve environmental management in pre-mining, mining and post-mining stages.

KBN Group first monitors and prepares a thorough study on environmental conditions prior to land clearing and decides on environmental management actions to be taken so as not to affect the surrounding community or the ecosystem itself. Several examples of these actions are animal conservation, air and dust monitoring, storage of topsoil for mine closure, and reclamation and revegetation. KBN Group also cooperates with accredited laboratories recommended by the government, in which the laboratory results will be used by KBN Group as reference to improve the quality of the Company in environmental management. The environmental performance programs are including but not limited to following areas:

Water quality management and monitoring:

Mine site water is usually acidic and therefore not fit for consumption or to be channelled directly to the river, as it may damage the river ecosystem. KBN Group manages such water with special techniques by having the Sediment Pond and Settling Ponds for treatment of water in order to produce water which meets environmental quality standards required by the Government.
To ensure the quality of the treated water, the pH of treated water checked every day, the treated water samples sent to the accredited Laboratory every month. Also, the water samples from the river are tested periodically in compliance to the Goverment regulations for monitoring.

Air Quality Management and Monitoring:

Dust from mining operational activities are intensively managed and monitored by monitoring air pollution level and spraying of water area impacted by dust using water trucks in the mining pit and on the hauling roads. Also, the air samples from the mine pit area, surrounding area are tested periodically in compliance to the Govt. regulations for monitoring.

Hazardous and Toxic Waste Management and Monitoring:

Hazardous and Toxic (B3) Waste Management requires special handling. For this reason, KBN Group cooperates with third parties with expertise in the handling of B3 Waste. The B3 waste is collected on daily basis in a separate room dedicated to B3 waste in order to prevent any spillage and contamination to the land and periodically disposed thru the accredited third parties for the waste handling and disposal.

Reclamation and Revegetation of Ex-Mine Areas:

In this activity, KBN Group utilized hydroseeding method to allow fast and optimum land revegetation in order to achieve targeted quality and quantity in reclamation and revegetation. KBN Group has their own dedicated Nursey for growing saplings and the team who have experience in plantation in the ex-mining areas. The Nursery and revegetation team uses all the required technique including the use of fertilizers for effective revegetation.
