JAKARTA - PT PLN (Persero) and PT Adhi Karya Tbk (Persero) are using the waste from coal combustion or Fly Ash and Bottom Ash (FABA) from the Asam Asam PLTU to build a 150 km long road in South Kalimantan Province.

General Manager of PLN's Main Generation and Distribution Unit (UIKL) Kalimantan, Daniel Eliawardhana explained that from this collaboration PLN sent 140 tons of FABA to Adhi Karya which was then used as an additive to replace cement in the concrete mixture in the infrastructure project.

"Optimization of the use of FABA, especially those produced by the PLTU owned by PLN, has been intensively carried out following the categorization of FABA into Non-Hazardous and Toxic (B3) waste," said Daniel, Wednesday 9 March.

Daniel detailed the 4x65 Mega-watt PLTU Asam-asam located in Tanah Laut Regency, South Kalimantan Province, which produces 160 tons of FABA per day in the production process.

"PLN cooperates with various parties in the use of FABA from coal combustion for various raw materials for the construction and infrastructure sectors around the PLTU Asam-asam location," added Daniel.

Daniel added that currently at the Asam-asam PLTU location, there are 500 thousand tons of FABA stock. Apart from being used by Adhi Karya, this FABA is also used by the surrounding community and local MSMEs to be processed into paving blocks and bricks.

"We proactively invite local governments, MSMEs, Village-Owned Enterprises and community groups to be able to utilize FABA into environmentally friendly products and provide a multiplier effect in increasing contributions to the economic sector," said Daniel.

FABA can be categorized as a by-product resulting from the coal combustion process in a steam power plant (PLTU).

In accordance with the 4M spirit of utilization (Easy, Cheap, Quality and Massive), PLN ensures that all environmental requirements and approvals have been complied with in accordance with national standards and regulations that refer to the international standard procedures of Best Available Techniques (BAT) and Best Environmental Practices (BEP). .
