In Pinaceae species, bark presents a composition enriched in extractives, lignin, and suberin, together with limited accessibility of structural polysaccharides, which collectively constrain conventional carbohydrate-driven valorization routes and require alternative processing strategies. This review examines Pinaceae bark as a dedicated feedstock for forest biorefineries by explicitly linking compositional features with fractionation strategies and downstream conversion pathways within a systems-oriented framework. Fractionation approaches, including conventional hydroalcoholic extraction, emerging solvent systems, and process intensification techniques, are critically assessed in terms of selectivity, scalability, and mass transfer limitations associated with bark structure. Downstream conversion routes are comparatively evaluated across thermochemical, hydrothermal, biochemical, and material-oriented pathways, highlighting the dominant suitability of lignin-rich residues for thermochemical processing and the conditional feasibility of biochemical conversion under intensified pretreatment schemes. Order-of-magnitude mass and energy considerations are incorporated to elucidate process interdependencies, trade-offs, and the role of internal energy recovery, providing a quantitative basis for assessing integrated configurations. The analysis supports a staged processing strategy in which early extractive recovery is followed by the conversion of lignin- and suberin-rich fractions, establishing clear links between upstream fractionation and downstream performance. Overall, this work provides a structured and quantitatively informed perspective that advances beyond descriptive analyses by integrating compositional constraints, process design considerations, and system-level performance, thereby supporting the development of robust and value-oriented biorefinery concepts for Pinaceae bark.</p></div>","PeriodicalId":488,"journal":{"name":"Biomass Conversion and Biorefinery","volume":"16 19","pages":""},"PeriodicalIF":4.3,"publicationDate":"2026-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149132286","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Additionally, activated carbon carrier supplementation facilitated the adsorption of inhibitory extracellular polymeric substances (EPS) specifically protein (PN) and polysaccharide (PS) fractions, reducing mass transfer resistance and stabilizing digestion kinetics. Although net cellulose degradation remained unvaried across treatments due to rapid baseline microbial turnover, enzymatic addition shortened effective digestion lag times.

These residues represent promising renewable feedstocks for recovering value-added compounds and developing functional ingredients, nutraceuticals, cosmetic formulations, biomaterials, adsorbents, and bioenergy. However, effective valorization requires matrix-specific strategies that optimize extraction efficiency and selectivity, preserve target compound functionality, and address technological and economic constraints associated with industrial scale-up. This review critically examines the composition and valorization potential of major <i>Prunus</i> processing by-products and evaluates conventional and emerging extraction technologies for the recovery of high-value bioactive and functional compounds. Particular emphasis is placed on extraction mechanisms, selectivity, matrix-specific behavior, target compound stability, solvent sustainability, process intensification, and scale-up feasibility. The review further explores integrated biorefinery strategies for the sequential recovery of valuable fractions, including lipids, proteins, polyphenols, fibers and other functional components, from a single biomass stream. Key challenges, including raw material variability, detoxification of cyanogenic glycosides, solvent recovery, compound stability, process standardization, regulatory compliance, and techno-economic feasibility, are critically assessed. Addressing these barriers requires hybrid extraction platforms, life cycle assessment, techno-economic analysis, pilot-scale validation, AI-assisted process optimization, and continuous biorefinery systems.

For PC extraction, raw cocoa bean hulls (RCBH) and autoclave pretreated cocoa hulls (PTH) were subjected to a heat-assisted extraction (HAE) with water and to an ultrasound-assisted extraction (UAE) with water or 50% ethanol, while cellulose-rich materials were obtained by peracetic acid treatment.

Peracetic acid treatment promoted substantial delignification, increasing cellulose contents from 25.06 to 40.48% in the starting materials to 46.87–69.20% in the corresponding cellulose-rich fractions.

A preliminary screening evaluated multiple organic acids (formic acid (FA), oxalic acid, citric acid, and acetic acid) each paired with two mineral acids (HCl or H₂SO₄) to identify the most effective organic–inorganic combination; this selected acid pair (FA-HCl) was then optimised using a 3³ response surface design at 121 °C (solid-to-liquid ratio 1:10) to maximise xylose recovery while minimising degradation products (furfural and 5-hydroxymethylfurfural (5-HMF)).

The production of PHB was confirmed by both FTIR and GC–MS analyses. These results demonstrate a dual-acid pretreatment that validates high xylose recovery with minimal furan formation and subsequent PHB synthesis from a local lignocellulosic waste stream by limited conditioning.
