Biorefineries are pivotal in advancing sustainability, yet most studies remain confined to laboratory scales, lacking comprehensive industrial-level analyses. In this work, the experiments scaled up design and assess techno-economic environmental implications of a multiproduct biorefinery system producing antioxidant extracts, lignin, bioethanol from exhausted olive pomace, residual biomass oil extraction. Using process simulation life cycle assessment, five scenarios were evaluated, varying...

Abstract Olive trees are cultivated in more than 40 countries worldwide over 10 million hectares. In addition to olive oil, a large amount of biomass is produced annually. All this must be adequately handled and disposed of. Conventional disposal methods include direct burning or spreading fields, but has economical costs environmental concerns, as well wasting source energy chemicals. This review summarizes the most recent proposals for use derived from tree cultivation oil production...

This paper deals with the characterization of brewer’s spent grain (BSG) and optimization phosphoric acid pretreatment for this feedstock. The influence temperature concentration on BSG was studied, optimal conditions were found to be 155 °C 2% H3PO4. use both enzymatic hydrolysis together recovered 92% total sugars in BSG, mainly solubilized prehydrolysate (63%). Escherichia coli SL100 fermented mixed sugar solution containing hemicellulosic starchy glucose without previous detoxification...

Abstract BACKGROUND A number of residues are produced during the olive oil extraction process, such as crushed pits, leaves, pomace and exhaust pomace. In addition, pruning trees results in a huge amount biomass. All these lignocellulosic materials constitute source energy chemicals that can be used raw biorefineries. Among them, antioxidants particular interest due to their potential applications pharmaceutical food industry. RESULTS Supercritical fluid (SFE) was applied on three different...

This paper deals with a new approach for using olive tree pruning biomass as raw material ethanol and other chemical production. process includes water extraction step, followed by high solids loading dilute phosphoric acid pretreatment an ethanologenic Escherichia coli fermentation the conversion of all sugars released. Results show that operational conditions leading to maximal hemicelullosic sugar recovery in liquid fraction (near 70%) are 170 °C 0.5% (w/v) concentration. The mixed found...

Abstract Olive stones are the main solid byproducts obtained from olive oil production and table olives production. As a lignocellulosic material, use of for ethanol other chemicals has been proposed, particularly under biorefinery concept. part such process, this work deals with fractionation material by dilute acid autoclave pretreatment at 2% sulfuric acid, 130°C, 60 min 1:1 liquid to ratio. Moreover, addresses fermentation liquors after pretreatment. The released sugars composed mainly...

This research study evaluates the techno-economic and environmental performance of an olive leaves based biorefinery to produce antioxidants, bioethanol, organosolv lignin. The comprises processes such as extraction, pretreatment simultaneous saccharification fermentation, which were simulated in Aspen Plus v9.0. Experimental data used simulate process, assuming a linear up-scaling. evaluation was carried out considering financial indicators net present value (NPV) internal rate return...

Olive tree biomass (OTB) represents an interesting feedstock for bioethanol production. In this study, olive pruning was water extracted and pretreated by dilute sulfuric acid to achieve high sugar recoveries from cellulosic hemicellulosic fractions. Temperature (160 200 °C), concentration (0 8 g acid/100 raw material), solids loading (15% 35% w/v) were selected as operation variables modified according a Box-Behnken experimental design. The optimal conditions the pretreatment 160 °C, 4.9...

Abstract Olive tree crops, extensively cultivated in Southern European countries, yield large amounts of olive pruning (OTP) biomass. This could be used within the framework a bio-based economy that maximizes utilization biomass resources sustainable way. In present work, techno-economic feasibility an OTP-based integrated biorefinery is evaluated by process simulation software Aspen Plus, while aimed at production ethanol, xylitol, antioxidants and electricity. Overall, proposed plant...

This study presents the development of iron oxide/activated hydrochar composites from brewer's spent grain (BSG) to remove 2-chlorophenol (2-CP) water via adsorption and Fenton oxidation. Two synthesis methods were employed: (1) incipient wetness impregnation hydrothermal carbonization (FeOHC) (2) chemical coprecipitation oxide onto surface (FeOHC-C). Characterization revealed mesoporous structures with areas ranging 44 66 m² g⁻¹ magnetite (Fe₃O₄) as predominant phase. Adsorption studies...

This study explores the integration of bioenergy with carbon capture and storage (BECCS) into a biorefinery system that converts olive tree prunings bioethanol antioxidants.
