Engineered biochar as a powerful tool for microplastics removal from wastewater: a critical review.
Review in Environmental geochemistry and health, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Microplastics (MPs) pollution in aquatic environment is considered as a critical environmental issue because of widespread and increasing use of plastics worldwide. Hence, engineered biochar known for its superior surface characteristics, enhanced surface area, greater porous structure and versatility has appeared as a sustainable and potential material for effective MPs removal from wastewater. To date, engineered biochar for MPs removal has received limited attention in reviews. Therefore, this article systematically summarizes the biochar production from low-cost and nature-friendly materials and potential modification methods to develop engineered biochars with improved performance for MPs adsorption from wastewater. Engineered biochar shows significantly higher adsorption compared to raw or pristine biochar. In this review, we critically examine emerging and novel biochar modification methods-including treatment with acid/bases, oxidizing agents, metallic oxides, non-metal compounds, clay minerals and nanomaterials which are typically applied for enhanced MPs removal from wastewater. Moreover, the discussion provides insights into the MPs removal mechanisms and the environmental factors that impact the adsorption performance of engineered biochar. We also discuss the costs of producing biochar and regeneration methods to restore its effectiveness thus revealing its viability and economic feasibility. It is anticipated that this critical review will provide comprehensive scientific breakthroughs for resolving the hot issue of MPs contamination in wastewater by proving engineered biochar application as an economical and nature-friendly solution. At the end, review outlines the present scientific knowledge, research gaps, and recommendations needed to advance technologies for mitigating MPs pollution from wastewater using engineered biochar.
