Environmental sustainability can be achieved through advanced natural, clean, and green technologies. Efficient and affordable strategies are required for water management, which is vital for environmental development. Vermifiltration, a natural bio-filtration technology, utilizes the enzyme activity of earthworms to digest organic waste materials present in the wastewater. This innovative approach creates a clean and green environment thereby supporting global food security. It plays a key role in climate-smart agriculture, addressing the complex challenges faced in modern farming practices. Earthworms decompose organic waste into valuable natural manure, enhancing soil fertility and improving soil physicochemical characteristics. Sustainable agriculture reduces the use of growth hormones and chemical fertilizers. This technology bridges sustainability to wastewater management through trickling filters that optimize the conversion of organic materials. Trickling filter-enabled vermifiltration extends the aerobic environment within the wastewater treatment system, promoting the effective decomposition of organic wastes. This novel treatment method improves hydraulic loading rate (HLR), hydraulic retention time (HRT), and other physicochemical parameters, maximizing the conversion of organic substances through the earthworms' eco-friendly engineering activity.
