InfoSAWIT, JAKARTA - After being successful to develop one biogas plant in Riau Province, BGA Group planned to continue construct other mills. With the support of biogas plant using Covered Lagoon Digester and completed by waste water treatment, in fact, the company realizes net zero emission with the final liquid waste that can be recycled in the mills.

This could be one way to reduce green-house gas (GHG) emission that is taken as the cause of climate change. This is the same with the government’s efforts to reduce carbon emission. BGA also targeted to reduce emission up to 30% in 2023.

Bumitama planned to continue develop biogas plants in 9 mills of the company in Central Kalimantan and West Kalimantan in the future.

Mill System and Continuous Improvement Dept. Head BGA Group Rieza Rakhman said, the mills produce waste (fiber, shell, and empty bunches), and palm oil mill effluent (POME).

For information, in processing liquid waste, there were chemical reaction that would produce methane gas that would deliver impacts to warming globally. The main thing from the process is biodegradation of waste organic component.

Anaerobic decomposition covers organic material process to decompose compound organic materials to be organic acid compound and then it is composed to be gas and water. Methane gas produced from the process is the biggest biogas components.

Gas methane can be taken for advantages or conversed as source of energy if it is processed in anaerobic digester system from chemical energy that uses gas engine and then changed to be electricity by alternator gas engine.

“It should be distributed to the places where they need or PT PLN. In the cooperation it is for PT Pasadena Biofuels Mandiri and PT PLN (Persero) Unit Distribusi Riau and Kepulauan Riau,” Rieza said. (T2)
