Environmental pollution has become a pressing concern worldwide due to the accumulation of pollutants from industries and agricultural sectors in soil and water environments. Heavy metals pose severe hazards to the environment, plants, and human health. Consequently, an eco-friendly technique is needed to combat environmental pollutants. Vermibiochar, a product prepared through the combined action of earthworms and biochar, demonstrates great potential in reducing heavy metal concentrations in contaminated soil. Its large surface area and high cation exchange capacity enhance the sorption of contaminants onto the vermibiochar surface, reducing their bioavailability. This review highlights the roles played by earthworms and biochar in heavy metal detoxification and immobilization. It discusses the current methods of remediation, vermibiochar production, its effects on soil properties and plant growth, and biochar’s impact on earthworm growth and reproduction. The studies reviewed suggest that vermibiochar is a novel strategy for addressing heavy metal contamination.

Abstract

Environmental pollution has become a pressing concern worldwide due to the accumulation of pollutants from industries and agricultural sectors in soil and water environments. Heavy metals pose severe hazards to the environment, plants, and human health. Consequently, an eco-friendly technique is needed to combat environmental pollutants. Vermibiochar, a product prepared through the combined action of earthworms and biochar, demonstrates great potential in reducing heavy metal concentrations in contaminated soil. Its large surface area and high cation exchange capacity enhance the sorption of contaminants onto the vermibiochar surface, reducing their bioavailability. This review highlights the roles played by earthworms and biochar in heavy metal detoxification and immobilization. It discusses the current methods of remediation, vermibiochar production, its effects on soil properties and plant growth, and biochar’s impact on earthworm growth and reproduction. The studies reviewed suggest that vermibiochar is a novel strategy for addressing heavy metal contamination.
