Safeguarding the Environment Waste and Effluent Management BPlant has instituted a reuse, reduce, and recycle initiative by deploying recycling bins at each of our operational units to divert waste from landfills. Scheduled waste management systems are in place at every operational site where they are managed by licenced scheduled waste contractors tasked with handling our scheduled waste. To ensure compliance with the Environmental Quality (Scheduled Waste) Regulations 2005, annual sustainability internal audits are conducted to verify proper waste disposal practices. Various byproducts are generated from our operations, including EFB, shell, and POME. These byproducts are utilised to generate energy during milling operations, while EFB mulch serves as organic fertiliser that is applied in our plantations. Before POME is discharged, it undergoes three phases of treatment used at respective palm oil mills: Phase 1 involves Primary Treatment, Phase 2 includes Secondary Treatment, and Phase 3 comprises Tertiary Treatment. Following these treatment phases, sampling is conducted to ensure that effluent parameters remain compliant with regulations. 01 02 03 Primary Treatment Secondary Treatment Tertiary Treatment Utilising a Multi-Disc Screw Press to remove suspended solids such as sand, silt, and grit from the system, thereby enhancing the treatment process Involving a biological process that includes anaerobic, aerobic, and facultative processes to decompose organic substances effectively Employing a Membrane Bio-Reactor or Sequential Batch Reactor to further reduce contaminants, particularly focusing on the Biological Oxygen Demand parameter BPlant’s Progress Air Management Our palm oil mill has been installed with nine Electrostatic Precipitators (ESP) and one wet scrubber. The functions of these system are to remove fine dust and particulate matter. The wet scrubber and ESPs employed in our palm oil mills in contrast, are equipped with a Continuous Emissions Monitoring System, enabling us to monitor emissions in real-time tracking. From 2021 through 2023, we consistently recorded an average particulate matter (PM) level of less than 150 mg per m3 which falls below the stack emissions threshold established by the Department of Environment. 2023 Limit of PM released after air treatment <150 mg per m3 Boustead Plantations Berhad 162
