The capture and utilization of biogenic CO₂ offer a promising route to carbon circularity and climate change mitigation through the production of renewable, high-value biochemicals. This study presents an integrated environmental and economic evaluation of emerging bioprocesses that convert biogenic CO₂ into value-added chemicals using gas and liquid fermentation pathways. Life cycle assessment and life cycle costing are employed to evaluate the environmental and economic performance. A hybrid multi-criteria decision-making framework, combining the Analytic Hierarchy Process and the Technique for Order Preference by Similarity to Ideal Solution, ranks the alternatives based on their environmental, economic, and technological attributes. The results indicate that the pathways can achieve net-negative greenhouse gas emissions, ranging from −2.43 to −0.38 kg CO_2eq per kg of biochemical, primarily due to the permanent sequestration of biogenic carbon within the final products. Production costs, assessed at the pilot scale, vary between €15.17 and €23.21 per kg, highlighting the influence of scale and process configuration.

Apple pomace resulted in the highest 2-PE productivity in shake flasks, reaching 44.5 mg.L⁻¹.h⁻¹-(1.07 g.L⁻¹ in 24 h), while its upscaling to a 1 L bioreactor led to 1.60 g.L⁻¹ in 48 h. Fermentation of acid whey supplemented with yeast extract and minerals for growth purposes significantly improved the bioconversion, leading to 2.64 g.L⁻¹ of 2-PE in 72 h. Using a membrane-based solvent extraction system, 2-PE was recovered efficiently from a glucose fermentation medium without impacting cell-specific product yield, showing promise for 2-PE recovery from waste-stream-based fermentation processes. The economic viability and environmental impacts of this process were also assessed based on process simulations of 2-PE fermentation at industrial scale. Techno-economic assessment showed that 2-PE production from whey was highly profitable, with a unit production cost of US$186 per kg and an internal rate of return of 24.9%. Life cycle analysis indicated that 2-PE fermentation has 1500 times lower greenhouse gas emissions than conventional 2-PE produced by extraction from roses.

A continuous agitated cell reactor was used to intensify the extractive reaction using methyl isobutyl ketone as an extractive phase to isolate <i>in situ</i> the furan products obtained by dehydration of hemicellulose sugars in aqueous media, using sulfuric acid as catalyst. The study, as part of a two-stage investigation, examined the influences of reaction temperature (110–140 °C), residence time (30–120 min), catalyst concentration (0.1–0.2 mol L⁻¹) and agitation frequency (2–9 Hz) in a single-phase medium using a definitive screening design of experiment. The aim of this initial experimentation stage was to identify the most statistically significant variables, which would serve as a benchmark for the subsequent evaluation of a biphasic medium. The highest glucose and xylose conversions obtained for single-phase aqueous operation were 30.6% and 61.4%, respectively, achieved for the highest temperature of 140 °C and 120 min residence time. At these conversions, the yield was 3.6% for 5-HMF, and 27.9% for furfural. The low yield was due to the degradation of the reactive intermediate furans in the aqueous phase. Acid concentration and the agitation frequency showed a significant effect on the conversion of the sugars. When using the biphasic extractive reaction system at 125 °C and 120 min residence time, the conversion of glucose and xylose rose to 45.9% and 78.5%, respectively, and the selectivity of 5-HMF (23.1%) and furfural (83.4%) and the yields (10.6% for 5-HMF and 65.5% for furfural) of furan in the biphasic system more than doubled in comparison with the use of single-phase operation. Two industrial hemicellulose hydrolysates were also investigated in a biphasic system, with one achieving maximum yields of 5-HMF and furfural at 21.7% and 37.9%, respectively, influenced by its higher oligomer content.

Quantifying these benefits requires quantitative assessment tools such as life cycle assessment (LCA). However, the LCA of biobased materials is not straightforward due to the complexity of addressing agroecosystem carbon dynamics and the timing of emissions. The aim of this research is to apply the novel framework of biobased materials and products-life cycle assessment (BBM-LCA) to the example of polylactic acid (PLA) to show how it can address biogenic carbon and timing issues of emissions by combining net ecosystem exchange (NEE) and dynamic LCA. BBM-LCA adapts two aspects of conventional LCA to estimate the climate impact of biobased products more accurately. First, concerning the absorption of atmospheric carbon during cultivation, BBM-LCA uses NEE to account for all biogenic emissions occurring within the agricultural ecosystem. This means that it is not limited to the absorption of carbon by agricultural crops. Second, concerning the calculation of climate impacts, BBM-LCA adopts dynamic LCA as a time-dependent approach, to generate a time-sensitive global warming potential (GWP). The example of PLA proves that BBM-LCA is an effective instrument for calculating the climate impact of biobased products due to the implementation of a holistic lifecycle approach and a dynamic impact calculation method. BBM-LCA accounts for the carbon sequestration benefits of recycling, recognizing its actual impact over time in multiple lifecycles. This feature makes BBM-LCA preferable over conventional LCA, which struggles to track greenhouse gas (GHG) emissions at different points over multiple years across the multiple lifecycles of recycled products.</p>","PeriodicalId":55380,"journal":{"name":"Biofuels Bioproducts & Biorefining-Biofpr","volume":"19 4","pages":"1075-1087"},"PeriodicalIF":3.2,"publicationDate":"2025-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/bbb.2769","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144646964","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This article evaluates appropriate technologies to convert biomass into electricity in three isolated areas (IAs): Amazon, Orinoco, and Pacific. The technical potential of agricultural residues (AR), livestock waste (LW), and municipal solid waste (MSW) was evaluated, and a total estimate of 3870.5 MW was obtained. Technologies considered were conventional Rankine cycle (CRC), organic Rankine cycle (ORC), and cycle with internal combustion engine cycle (ICE.C), with power outputs from 50 to 50 000 kW, investment costs from 2100 to 5120 USD/kW, and levelized electricity costs from 0.074 to 0.252 USD/kW. To match the per capita electricity consumption of the rest of the country, the estimated energy demand in these isolated areas was 380.2 MW. This corresponded to 3.3% of the theoretical energy potential of agricultural waste biomass in those areas. Converting waste biomass into electrical energy is an option for the farming sector, as it would allow it to manage its waste more efficiently and add value.
