Environmental Aspects


The Company is committed to always maintaining the quality of the environment in every operation area of the Company and its subsidiaries.

The Company realizes that the business activities of the Company and its subsidiaries have direct and indirect impacts and risks on environment. The business activities of the Company and its subsidiaries, especially in coal mining sector, are directly related to the environment and therefore it is necessary to plan and realize an adequate environmental management so that the quality of the environment in the operational area can always be maintained, restored and/or improved responsibly during and after operations.


Programs related to environmental aspect that had been implemented by the Company and its subsidiaries during 2019 to 2021, among others, are as follows:

Energy Consumption
Efficient and responsible use of energy is one of BIB’s commitments to minimize environmental impacts resulted from its mining operation activities as well as to maintain the quality of life of the local communities around the operational areas.

The Company through its subsidiary has been using solar power as well as B20 and B30-graded biodiesel in its mining activities.

Information regarding BIB’s energy consumption can be seen in the table below:

Greenhouse Gas Emission Management
The consumption of energy in operational activities of BIB generated GHG emissions. Therefore, BIB has always been striving to reduce its GHG emissions as a form of support and active role in reducing the global warming rate as well as eliminating the negative impacts of climate change.

Information regarding BIB’s GHG emission and its intensity can be seen in the chart and table below:


Air Quality Management
In addition to releasing GHG emissions into the atmosphere, coal mining activities also generates several other air pollutants in the form of nitrogen oxides (NOx), carbon monoxide (CO), sulfur oxides (SOx), and total suspended particles (TSP). These air pollutants could create a negative health impact on stakeholders who are in or around BIB’s operational areas, such as employees, suppliers, contractors, and local communities.

To prevent negative health impacts, BIB has implemented an air quality management program to monitor and maintain air quality so that it remains within the threshold set by the government. BIB has worked with an accredited external laboratory to regularly monitor air quality around its operational areas. The results of the laboratory tests were submitted to the local Environmental Department.

The charts below illustrate the average value per year versus the threshold for each pollutant in various operational areas of BIB:



Waste Management
In performing its operational activities, BIB generates wastes in the form of overburden, hazardous wastes, and non-hazardous wastes. The hazardous wastes consist of lubricants, rags, grease, filters, hoses, and automotive batteries. Whereas the non-hazardous wastes consist of tires, metal scraps, papers, and plastics.

In 2021, BIB worked with a contractor to manage its hazardous and non-hazardous wastes. The management of hazardous solid wastes was carried out in accordance with the Hazardous Waste Handling and Storage Policy which has met the national standards from the Ministry of Environment and Forestry. Under this policy, contractors who have been registered and approved should collect the materials every month to prevent overload.

In addition to hiring contractors, for the management of non-hazardous wastes, BIB also engaged employees and the local communities around the operating areas to participate in minimizing waste by utilizing the waste into compost and raw materials for pellet production.

Water Resource and Effluent Management
To monitor the efficiency of our water usage at facilities or processes in operational activities at BIB, water management and conservation policies and programs were implemented. The water management includes water footprint and life cycle assessment, revegetation of plants on river borders, prevention of waste disposal, liquid in water bodies and installation of TMA loggers. External stakeholder engagements are also involved through a yearly site verification conducted by the central and local government on our water management systems and practices. The feedbacks received will be used as input for improvements.

Land Management
BIB always seeks to carry out good land management to prevent environmental contamination, erosion, and landslides. BIB is committed to rehabilitating land, affected by BIB’s mining operations, back to its original condition to ensure that there are no long-term side effects that could potentially endanger the health of the people, environment, and biodiversity.

In 2021, BIB had rehabilitated 35.8 ha of land or about 42.7% of the yearly rehabilitation target of 83.94 ha. BIB had also planted more than 29,813 trees in 2021. Through the rehabilitation activities (such as tree plantation activities), it is expected that the post-mining carrying capacity of the ecosystem would be restored to its initial state.
