The presence of pith creates process-related issues in papermaking, so it must be removed from the bagasse. Pith has low calorific value, and burning of pith in boilers also creates boiler operational issues as well as environmental pollution and health hazards. The imposition of stringent emission norms by the environmental regulatory bodies is compelling these industries to search for cleaner alternatives to fuels. Pith is generated in huge quantities so its disposal or management will become a major challenge if industries shift to cleaner fuel. Considering these pressing issues and some recent relevant research reported on pith valorization, this study was planned to explore the potential of pith valorization. Therefore, in the present review, research studies available on alternate routes for the valorization of pith into value-added products have been extensively covered. Since pith is also lignocellulosic biomass, therefore, its valorization after pretreatment and as such direct utilization (without pretreatment) has also been categorically discussed. Furthermore, the promising pathways and prospective research in pith valorization are discussed that will make the sugar and associated pulp and paper mill more economically and environmentally sustainable.</p></div>","PeriodicalId":487,"journal":{"name":"BioEnergy Research","volume":"16 3","pages":"1280 - 1295"},"PeriodicalIF":3.6,"publicationDate":"2023-07-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"4752433","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There are important gaps in HTL reaction optimization, process design, and the effect of operating parameters. To facilitate overcoming these research gaps in future studies, this review summarizes the scientific and engineering applications of HTL. The objective of this study is to assess the production of biocrude from algae using HTL and compare it with wood and waste biomasses as a potential feedstock. The influence of effective parameters on the optimum HTL biocrude yield was investigated. Moreover, kinetic, economic, and exergy analyses have been considered in HTL studies. The result showed that the highest biocrude yield was attained at 50 wt%, 30 wt%, and 20 wt% using microalgae, wood, and macroalgae at an optimum temperature range of 300–350?°C for less than 60?min. The kinetic models were successful at all reaction temperatures and times for biocrude yield prediction. Moreover, the minimum fuel selling price varied between $1.70 and $22/GGE. The exergy studies indicated that the overall exergy efficiency was in the range of 20–96%. However, direct HTL has some drawbacks such as severe operation conditions and biocrude production with high nitrogen and oxygen contents. Several processes were considered to address these problems. The two-stage, microwave, catalytic cracking, additives, and hydro-treatment upgrading process improve the biocrude properties, while the supercritical fluids and emulsification upgrading process helped dissolve insoluble materials. Furthermore, pretreatment processes such as bead milling, ultrasonic, and microwave were suggested to promote biomass cell wall disruption.</p></div>","PeriodicalId":487,"journal":{"name":"BioEnergy Research","volume":"16 3","pages":"1493 - 1511"},"PeriodicalIF":3.6,"publicationDate":"2023-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"4388968","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The increase in biogas production was investigated through batch tests using basic BMP equipment, while synergistic effects were evaluated by chemical oxygen demand (COD) balance. Analyses were performed in four volume basis ratios (3/1, 1/1, 1/3, 1/0) of primary sludge and food waste with added low food waste: 3.375%, 4.675%, and 5.35%, respectively. The best proportion was found to be 1/3 with the maximum biogas production (618.7 mL/g VS added) and the organic removal of 52.8% COD elimination. The highest enhancement rate was observed among co-digs 3/1 and 1/1 (105.72 mL/g VS). A positive correlation between biogas yield and COD removal is noticed while microbial flux required an optimal pH, value of 8 significantly decreased daily production rate. COD reductions further supported the synergistic impact; specifically, an additional 7.1%, 12.8%, and 17% of COD were converted into biogas during the co-digestions 1, 2, and 3, respectively. Three mathematical models were applied to estimate the kinetic parameters and check the accuracy of the experiment. The first-order model with a hydrolysis rate of 0.23-0.27 indicated rapidly biodegradable co-/substrates, modified Gompertz confirmed immediate commencement of co-digs through zero lag phase, while the Cone model had the best fit of over 99% for all trials. Finally, the study points out that the COD method based on linear dependence can be used for developing relatively accurate model for biogas potential estimation in anaerobic digestors.</p><p><strong>Supplementary information: </strong>The online version contains supplementary material available at 10.1007/s12155-023-10620-8.</p>","PeriodicalId":487,"journal":{"name":"BioEnergy Research","volume":" ","pages":"1-14"},"PeriodicalIF":3.6,"publicationDate":"2023-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10241376/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9714662","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To overcome this, the AD process is often combined with pretreatment techniques, which facilitate the breaking of organic feedstock into smaller molecules and eventually result in enhanced biogas production. Among several techniques, ultrasound-assisted pretreatment of AD feedstock remains promising because it is simple to implement, requires no chemicals, and combines physical (or cavitation) and biological phenomena for degrading AD feed. This review is primarily centered on the applications of ultrasound pretreatment for disintegrating various feedstocks and increasing biogas production during AD. Biogas generation is described in relation to the ultrasound-assisted disintegration of dairy industry waste, hybrid food and municipal wastes, olive mill wastewater, rice straw, tannery wastewater, meat processing sludge, hybrid industrial waste municipal sewage sludge, and lignocellulosic biomass. The disintegration schemes of feedstocks under ultrasound are proposed. COD is solubilized, and suspended solids (SS) are reduced upon ultrasonication. The impact of ultrasonic treatment on biogas production might be amplified if paired with alkali. Furthermore, the techno-economic commercial scopes of ultrasound pretreatment-based biogas production are discussed, and recommendations for future studies are suggested.</p><h3>Graphical Abstract</h3>\u0000 <figure><div><div><div><picture><source><img></source></picture></div></div></div></figure>\u0000 </div>","PeriodicalId":487,"journal":{"name":"BioEnergy Research","volume":"16 3","pages":"1512 - 1527"},"PeriodicalIF":3.6,"publicationDate":"2023-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"4222545","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study used the second-generation (2G) fermentable sugar (2G FS) recovered from the low-cost feedstock sugarcane bagasse as a substrate for 1,3-PDO production through a mixed culture fermentation in a single pot using <i>Saccharomyces cerevisiae</i> NCIM 3594 and <i>Klebsiella pneumoniae</i> NCIM 2957.
