This review presents a comprehensive analysis of existing POME treatment technologies, including anaerobic digestion (AD), advanced oxidation processes (AOPs), membrane filtration, adsorption, phytoremediation, and microalgae-based systems. Each method is examined in terms of treatment efficiency, operational feasibility, and potential for implementation under Indonesian conditions. While advanced processes, such as AOPs and membrane filtration, achieve high pollutant removal, they are often limited by operational costs. In contrast, biological approaches, such as AD and phytoremediation, offer both environmental benefits and economic value through the recovery of biogas, biofertilizers, and biomass. This review highlights the potential for integrating wastewater purification with resource recovery and valorization, supporting a shift toward more circular and sustainable management of POME.

However, tar generation during the gasification remains an issue, affecting operational efficiency and environmental health. Biochar has been confirmed as an inexpensive and efficient catalyst for tar removal. The challenge lies in creating a highly reactive biochar which can be applied for different types of biomass with varying properties. This review discusses the factors that affect biochar's reactivity as a catalyst for tar reforming. Additionally, incorporating biochar into a gasification scenario with raw biomass offers a practical solution by leveraging the synergistic behavior. However, this synergy could be either positive or negative: the positive synergy enhances tar removal while the negative synergy has the opposite effect. The numerous factors affecting the results of gasification are presented in this review. It is concluded that the positive synergistic effect resulted from the balance between the available reactants from biomass and biochar, the optimal gas flowrate and the active sites on the carbon surface. Understanding these interactions is crucial for optimizing biochar performance for tar removal. Ultimately, this research provides insights into biochar's role in biomass gasification and suggests improvements for future studies to enhance the feasibility of biomass gasification with the assistance of biochar.</div></div>","PeriodicalId":101081,"journal":{"name":"Resources Chemicals and Materials","volume":"4 3","pages":"Article 100115"},"PeriodicalIF":0.0,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143891380","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
