Safeguarding Environmental Quality in Weda Bay, IWIP Ensures Measured Management of FABA

PT Indonesia Weda Bay Industrial Park (IWIP) is committed to safeguarding environmental quality in the Weda Bay industrial zone, Central Halmahera, North Maluku. This commitment is implemented, among other things, through the management of fly ash and bottom ash (FABA), applying measured technology and operational procedures. Corporate Environmental Manager of PT IWIP, Yofi Safutra, stated that IWIP has implemented an emission control system designed to minimise potential impacts on the environment and surrounding communities. “The fly ash produced from the combustion process is captured using Electrostatic Precipitator (ESP) technology with high efficiency. This technology functions to control particles so they do not escape into the free air,” said Yofi in his statement on Tuesday, 14 April 2026. In addition to fly ash, IWIP also manages bottom ash, which consists of larger particles that settle at the bottom of the combustion furnace. This material is collected directly from the boiler system and placed in specially designed storage facilities to prevent potential spread to the environment. Furthermore, Yofi emphasised that the entire FABA management process is carried out in reference to approved environmental documents and applicable national regulations. “We also conduct regular monitoring of ambient air quality and other environmental parameters to ensure that all operations continue to meet the established quality standards,” he said. Under certain conditions and through processes that meet requirements, this material can be reused or recycled as a supporting material in various industrial needs. In its implementation, IWIP utilises FABA as an alternative raw material for construction products such as bricks, paving blocks, concrete blocks, and as a substitute material in concrete mixtures. This utilisation is applied in various internal company infrastructure developments, such as employee sports facilities, gardens, accommodation, pedestrian paths, and other maintenance activities. “Through the application of technology and sustainable management, IWIP strives to ensure that the potential impacts of FABA can be controlled while supporting environmentally responsible industrial operations,” he stated. For information, fly ash is fine particles resulting from the combustion of materials containing minerals, particularly from the use of coal in power plants. Meanwhile, bottom ash consists of heavier particles that settle at the bottom of the combustion furnace.
