It focuses on utilizing biochar-based composites for the efficient removal of microplastics. Biochar, derived from biomass pyrolysis, possesses a high surface area and adsorption capacity, rendering it well-suited for wastewater treatment. The chapter commences with an overview of the microplastic problem, emphasizing its environmental ramifications and the limitations of conventional wastewater treatment techniques. It subsequently examines the properties of biochar that render it effective for microplastic adsorption, such as its porous structure and chemical composition. This chapter emphasizes the urgent need for proactive steps to combat microplastic contamination by looking at the causes and consequences of microplastics in wastewater and assessing the efficacy of both conventional and innovative treatment approaches. To mitigate microplastic contamination in wastewater and promote sustainable water management practices while protecting the environment and public health, it closes by underlining the substantial potential of biochar-based composites. © 2025 selection and editorial matter, Tonni Agustiono Kurniawan and Abdelkader Anouzla; individual chapters, the contributors.enComposite materialsEnvironmental managementMicroplasticPublic healthReclamationWater conservationWater pollutionAdsorption capacitiesBiocharBiomass pyrolysisEnvironmental ramificationsHigh surface areaInnovative strategiesIt focusMicroplasticsSurface adsorptionWaste water systemsWastewater treatmentbook-chapter
