BioBrew is a low-cost wastewater treatment system designed for small coffee farms. Using vermifiltration, it harnesses earthworms and microbes to purify wastewater while composting coffee pulp into nutrient-rich fertiliser. Modular, scalable, and locally sourced, BioBrew tackles water pollution and soil degradation, supporting sustainable farming and improving both ecological health and farmers’ livelihoods.
