Sustainable and effective wastewater treatment strategies are urgently needed to address this issue. 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.

This review is devoted to summarizing the general strategies adopted in various gasifiers to reduce tar formation for high-efficiency clean gasification. For single-bed and staged-gasification processes, their low-tar strategies are typically different. In the single-bed processes, the low-tar strategies involve in-bed intensification achieved by controlling flow directions of gas and particles inside the gasifier. During the gasification, these two components often have different temperatures to facilitate thermochemical interactions between them. Meanwhile, the two-stage gasifiers are generally designed to decouple pyrolysis, gasification and tar cracking reactions for maximizing the benefits (such as yield and efficiency) realized from the interactions among these reactions. In addition to minimizing tar formation, the approach of reaction decoupling can also raise the calorific value of product gas, even without use of oxygen, and/or improve the adaptability of gasification technology to the feedstocks with various moisture contents and particle sizes. The reanalysis based on those essential low-tar strategies is expected to gain alternative insights into the reaction principles implicated in most advanced biomass gasification technologies.</div></div>","PeriodicalId":101081,"journal":{"name":"Resources Chemicals and Materials","volume":"4 2","pages":"Article 100087"},"PeriodicalIF":0.0,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144713517","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}
