An integrated gasification combined cycle (IGCC) is configured using different feedstock spanning from torrefied food waste to biomass and coal using O 2 / steam as the gasifying medium. The HHV of syngas generated from TFW is found to be 11.2 MJ/kg at 900℃ at ER 0.35. The present study highlights the effect of torrefaction over raw biomass and coal using a combined cycle for power generation for an energy input of 200 MW. The sensitivity analysis of each case is studied by varying the oxidant flow, steam flow and operating temperature to determine the optimum conditions. The techno-economic analysis suggested that the cost (128.18 $ /MWh) is somewhat higher than the coal and biomass. This clearly suggests implementing torrefied feed over raw biomass, biomass would require subsidy by government. The net efficiency of the proposed plants are found to be 30.4%, 35.46% and 38.27% using SB, TFW and IC, respectively. Further, it can be inferred that it can possibly replace fossil fuels or can be added as a blend for value-added products generation. torrefied food waste gasification power production cost of electricity Full Text Cite Share Download PDF Status: Published Journal Publication published 13 Mar, 2026 Read the published version in Waste and Biomass Valorization → Version 1 posted Reviewers agreed at journal 03 Nov, 2025 Reviewers invited by journal 03 Nov, 2025 Editor invited by journal 01 Nov, 2025 Editor assigned by journal 13 Oct, 2025 First submitted to journal 13 Oct, 2025 You are reading this latest preprint version Research Square lets you share your work early, gain feedback from the community, and start making changes to your manuscript prior to peer review in a journal.

250℃ in inert atmosphere. An integrated gasification combined cycle (IGCC) is configured using different feedstock spanning from torrefied food waste to biomass and coal using O\u003csub\u003e2\u003c/sub\u003e/ steam as the gasifying medium. The HHV of syngas generated from TFW is found to be 11.2 MJ/kg at 900℃ at ER 0.35. The present study highlights the effect of torrefaction over raw biomass and coal using a combined cycle for power generation for an energy input of 200 MW. The sensitivity analysis of each case is studied by varying the oxidant flow, steam flow and operating temperature to determine the optimum conditions. The techno-economic analysis suggested that the cost (128.18\u003cspan\u003e$\u003c/span\u003e/MWh) is somewhat higher than the coal and biomass. This clearly suggests implementing torrefied feed over raw biomass, biomass would require subsidy by government. The net efficiency of the proposed plants are found to be 30.4%, 35.46% and 38.27% using SB, TFW and IC, respectively. Further, it can be inferred that it can possibly replace fossil fuels or can be added as a blend for value-added products generation.\u003c/p\u003e","manuscriptTitle":"Evaluation of Torrefied Food Waste as a Renewable Feedstock for Power Production: Techno-Economic and Environmental Insights","msid":"","msnumber":"","nonDraftVersions":[{"code":1,"date":"2025-11-12 23:31:04","doi":"10.21203/rs.3.rs-7847487/v1","editorialEvents":[{"type":"communityComments","content":0},{"type":"reviewerAgreed","content":"","date":"2025-11-03T07:01:40+00:00","index":0,"fulltext":""},{"type":"reviewersInvited","content":"","date":"2025-11-03T06:39:36+00:00","index":"","fulltext":""},{"type":"editorInvited","content":"Waste and Biomass Valorization","date":"2025-11-01T15:20:11+00:00","index":"","fulltext":""},{"type":"editorAssigned","content":"","date":"2025-10-14T01:18:41+00:00","index":"","fulltext":""},{"type":"submitted","content":"Waste and Biomass Valorization","date":"2025-10-13T06:01:33+00:00","index":"","fulltext":""}],"status":"published","journal":{"display":true,"email":"[email protected]","identity":"waste-and-biomass-valorization","isNatureJournal":false,"hasQc":true,"allowDirectSubmit":false,"externalIdentity":"wave","sideBox":"Learn more about [Waste and Biomass Valorization](http://link.springer.com/journal/12649)","snPcode":"12649","submissionUrl":"https://submission.nature.com/new-submission/12649/3","title":"Waste and Biomass Valorization","twitterHandle":"","acdcEnabled":true,"dfaEnabled":true,"editorialSystem":"em","reportingPortfolio":"Springer Hybrid","inReviewEnabled":true,"inReviewRevisionsEnabled":false}}],"origin":"","ownerIdentity":"bcbaf4a1-4df7-4c96-b481-e2c798dc85f6","owner":[],"postedDate":"November 12th, 2025","published":true,"recentEditorialEvents":[],"rejectedJournal":[],"revision":"","amendment":"","status":"published-in-journal","subjectAreas":[],"tags":[],"updatedAt":"2026-03-16T16:06:48+00:00","versionOfRecord":{"articleIdentity":"rs-7847487","link":"https://doi.org/10.1007/s12649-026-03548-5","journal":{"identity":"waste-and-biomass-valorization","isVorOnly":false,"title":"Waste and Biomass Valorization"},"publishedOn":"2026-03-13 16:00:34","publishedOnDateReadable":"March 13th, 2026"},"versionCreatedAt":"2025-11-12 23:31:04","video":"","vorDoi":"10.1007/s12649-026-03548-5","vorDoiUrl":"https://doi.org/10.1007/s12649-026-03548-5","workflowStages":[]},"version":"v1","identity":"rs-7847487","journalConfig":"researchsquare"},"__N_SSP":true},"page":"/article/[identity]/[[...version]]","query":{"redirect":"/article/rs-7847487","identity":"rs-7847487","version":["v1"]},"buildId":"8U1c8b4HqxoKbykW_rLl7","isFallback":false,"isExperimentalCompile":false,"dynamicIds":[84888],"gssp":true,"scriptLoader":[]}
