In the heart of Indonesia’s thriving palm oil industry, a novel approach to managing one of its most significant waste challenges is gaining traction, with promising implications for both environmental sustainability and commercial viability. Palm Oil Mill Effluent (POME), a byproduct of crude palm oil (CPO) production, has long been a concern due to its low pH and high organic content. However, recent research published in the Sriwijaya Journal of Environment, which translates to the Sriwijaya Journal of Environmental Studies, suggests that sustainable management of POME through land application could be a game-changer.
Muhammad Izhar, a Magister Program Student on Management of Environmental Study at Sriwijaya University, Indonesia, led the study that evaluated the utilization of POME through land application at PT. X. The research focused on the palm oil mill liquid waste management system and its impact on surface water quality. “The land application method has been proposed as one solution to utilize POME sustainably,” Izhar explained. “Our study aimed to evaluate its effectiveness and potential risks.”
The findings were encouraging. The palm oil mill liquid waste management system at PT. X successfully reduced Biochemical Oxygen Demand (BOD) levels by 64.83%. BOD is a critical water quality parameter, indicating the amount of oxygen required by microorganisms to decompose organic matter. Lower BOD levels mean less pollution. Surface water quality tests conducted upstream and downstream of the activity location showed that most parameters were within the quality standards set by government regulations.
However, the study also highlighted the need for vigilant supervision. “Land application must always be carried out carefully,” Izhar cautioned. “If not managed properly, it can still pose a risk of water pollution.”
The commercial implications of this research are significant. Effective POME management can lead to reduced waste treatment costs and potential revenue from agricultural benefits, as the nutrients in POME can enrich the soil. This could be particularly beneficial for the energy sector, which relies heavily on palm oil as a feedstock for biodiesel production. Sustainable waste management practices can enhance the sector’s environmental credentials and contribute to a more circular economy.
The study’s findings could shape future developments in the field by promoting the adoption of land application methods for POME management. However, it also underscores the importance of robust monitoring and regulation to mitigate potential risks. As the palm oil industry continues to grow, so too will the need for innovative and sustainable waste management solutions. This research offers a promising path forward, one that balances commercial interests with environmental responsibility.
