IWIP Manages FABA in a Measured Manner to Preserve Environmental Quality

PT Indonesia Weda Bay Industrial Park (IWIP) is committed to preserving environmental quality in the Weda Bay industrial zone, Central Halmahera, North Maluku, including the management of fly ash and bottom ash (FABA) through the application of measured technology and operational procedures. Fly ash consists of fine particles resulting from the combustion of mineral-containing materials, primarily from coal use in coal-fired power plants (PLTU), while bottom ash comprises heavier particles that settle at the base of the combustion furnace. These particles have the potential to disperse into the air if not optimally controlled, necessitating proper management in accordance with regulations. IWIP’s Corporate Environmental Manager, Yofi Safutra, stated that the company 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 serves to control particles so they do not escape into the open air,” Yofi said. In addition to fly ash, IWIP also manages bottom ash, which consists of larger particles that settle at the base of the combustion furnace. This material is collected directly from the boiler system and placed in specially designed storage facilities to prevent potential dispersion into the environment. Furthermore, Yofi emphasised that all FABA management processes are 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,” Yofi added. 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, and concrete blocks, as well 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,” Yofi concluded.
