A detailed techno-economic analysis was also carried out to determine the economic feasibility of the process.</p><p><strong>Results and conclusions: </strong>The simulation results showed a biogas yield of 26.12 Nm³ per m³ POME, which is in line with industry data with less than 1 % deviation. The ANN model achieved a high coefficient of determination (R²) of 0.9 and a low mean squared error (MSE), with the bioscrubber reaching an H₂S removal efficiency of approx. 96 %. The techno-economic analysis showed that the process is feasible with a net present value (NPV) of $131 000 and a payback period of 7 years.</p><p><strong>Novelty and scientific contribution: </strong>The integration of ANN and the computer programme provides a robust framework for predicting bioscrubber performance and ensuring stable bioscrubber operation due to their complementary strengths. ANN accurately predicts H₂S removal based on daily recorded data, while the computer programme estimates parameters that are not monitored daily, such as chemical oxygen demand (COD), biological oxygen demand (BOD) and total suspended solids (TSS). This research provides valuable insights into sustainable biogas production practices and offers opportunities to improve energy efficiency and environmental sustainability in the palm oil industry.</p>","PeriodicalId":12400,"journal":{"name":"Food Technology and Biotechnology","volume":"63 2","pages":"124-133"},"PeriodicalIF":2.5,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12272170/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144741760","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
