This research transform waste (oil palm fronds and spent coffee grounds) into magnetic activated carbon bio-sorbents. The bio-sorbent functions as an efficient extraction tools to remove pesticides, dyes, organic pollutants, and heavy metals from the environment. It offers a low-cost, sustainable alternative to commercial sorbents, helping to reduce environmental pollution and agricultural waste. Additionally, this study led to the development of a magnetic activated carbon sorbent kit with commercial potential, supporting both environmental sustainability and economic value.
