[PMID: 38678906 DOI: 10.1016/j.jenvman.2024.120989] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/14/2024] [Revised: 03/25/2024] [Accepted: 04/20/2024] [Indexed: 05/01/2024]
Abstract
The efficient utilization of food waste (FW) resources through Food Waste Valorization (FWV) has received increasing attention in recent years. Various decision-making studies have been undertaken to facilitate FWV implementation, such as the studies on decision-making framework and FWV technology assessment. Food waste hierarchy is a widely discussed framework in FW management, but it was found too simplified and does not always contribute positively to environmental sustainability. Moreover, decision-making studies in FWV often focus on specific aspects of the food system and employ distinctive decision-making approaches, making it difficult to compare the results from different studies. Therefore, our literature review is conducted to provide a comprehensive understanding of FWV decision-making. This study identifies what decisions are needed, and three levels of decisions are revealed: system-level, FW stream-level, and FWV option-level. The assessment approaches and criteria used to support decision-making in FWV are also collected and analyzed. Building upon these findings, an hourglass model is synthesized to provide a holistic illustration of decision-making in FWV. This study untangles the complexities of FWV decision-making and sheds light on the limitations of current studies. We anticipate this study will make more people realize that FWV is a multidisciplinary issue and requires the collective participation of researchers, practitioners, policymakers, and consumers. Such collective engagement is essential to effectively address practical challenges and propel the transition of the current food system toward a more resource-efficient paradigm.

Gaffey J, Collins MN, Styles D. Review of methodological decisions in life cycle assessment (LCA) of biorefinery systems across feedstock categories. JOURNAL OF ENVIRONMENTAL MANAGEMENT 2024; 358:120813. [PMID: 38608573 DOI: 10.1016/j.jenvman.2024.120813] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/23/2023] [Revised: 01/14/2024] [Accepted: 04/01/2024] [Indexed: 04/14/2024]
Abstract
The application of life cycle assessment (LCA) to biorefineries is a necessary step to estimate their environmental sustainability. This review explores contemporary LCA biorefinery studies, across different feedstock categories, to understand approaches in dealing with key methodological decisions which arise, including system boundaries, consequential or attributional approach, allocation, inventory data, land use changes, product end-of-life (EOL), biogenic carbon storage, impact assessment and use of uncertainty analysis. From an initial collection of 81 studies, 59 were included within the final analysis, comprising 22 studies which involved dedicated feedstocks, 34 which involved residue feedstocks (including by-products and wastes), and a further 3 studies which involved multiple feedstocks derived from both dedicated and secondary sources. Many studies do not provide a comprehensive LCA assessment, often lacking detail on decisions taken, omitting key parts of the value chain, using generic data without uncertainty analyses, or omitting important impact categories. Only 28% of studies included some level of primary data, while 39% of studies did not undertake an uncertainty or sensitivity analysis. Just 8% of studies included data related to dLUC with a further 8% including iLUC, and only 14% of studies considering product end of life within their scope. The authors recommend more transparency in biorefinery LCA, with justification of key methodological decisions. A full value-chain approach should be adopted, to fully assess burdens and opportunities for biogenic carbon storage. We also propose a more prospective approach, taking into account future use of renewable energy sources, and opportunities for increasing circularity within bio-based value chains.

Abstract
This article aims to identify how project management can enable the introduction of circular economy (CE) in agribusiness. The methodological strategy used was the systematic literature review. The research corpus consisted of 70 articles selected from the Web of Science and Scopus databases. For screening, the Rayyan platform was used, and the analysis process was carried out by categorization and grouping of terms and concepts with the help of Excel software. The evidence shown the efforts to reduce agro-waste and how to transform them into by-products. Barriers, challenges, benefits and opportunities for making the CE viable in agribusiness are presented. Three ways of projecting the CE in agribusiness are identified: (1) project management processes in the integration of the CE in agribusiness, (2) innovative projects and new business models as drivers of the CE in agribusiness and (3) 4.0 technologies integrating the CE in agribusiness based on project management methodologies. Results are limited to terms used in search mechanisms. This research contributes towards identifying project management processes that can enable the CE in agribusiness, particularly by identifying the impacts of the CE in different business areas. The research also contributes in a practical way by providing insights on ways to make the CE viable in agribusiness through project management.

Polyphenolic Compounds in Extracts from Roasted Grapevine Canes: An Investigation for a Circular Approach to Increase Sustainability in the Viticulture Sectors. Molecules 2023; 28:7676.

Abstract
In this study, we compared the polyphenolic composition of the roasted grapevine wood chips of four Vitis vinifera cultivars-namely, Sorbara, Grasparossa, Malbo Gentile, and Spergola. These waste byproducts have the potential as infusion chips for the aging of alcoholic beverages and vinegars, contributing to an enriched sensory profile. Roasting amplifies aromatic nuances and triggers the depletion of crucial bioactive compounds, including polyphenols. We investigated the extent of polyphenolic loss in the ethanolic extract of roasted grapevine chips to repurpose this waste byproduct and assess its potential. We assessed the levels of trans-resveratrol, trans-ε-viniferin, trans-piceatannol, and the main resveratrol trimer. Our findings indicated a significant decrease in polyphenol content as the roasting temperature increased, from 16.85-21.12 mg GAE/g for grapevine chips roasted at 120 °C to 3.10-7.77 mg GAE/g for those roasted at 240 °C. This study also highlights notable genotypic differences in polyphenolic content. Among the red grape cultivars analyzed, Sorbara exhibited the highest levels (7.77-21.12 mg/GAEg), whereas the white grape cultivar Spergola showed the lowest polyphenolic content (3.10-16.85 mg/GAEg). These findings not only contribute to the scientific understanding of polyphenol stability but also hold practical implications for the enhancement of aged beverages, as well as advancing sustainable practices in the viticulture industries.

Abstract
The increase in the world population has led to intensive food production systems that are generating increasing amounts of solid waste. In this work, the valorization of the most important waste generated during wine production, grape pomace, is evaluated. Eight processes are proposed to approach different types of valorization (production of energy and value-added products), from economic, environmental, and social points of view. The best process depends on the budget available, the production capacity, and the weight of each impact produced by the factory (economic, environmental, or social). For small (less than 0.1 kg/s) or very large (greater than 10 kg/s) capacities, the production of high-value-added products outperforms the other processes in all three impacts and in profitability. For intermediate capacities, combustion and gasification stand out as having the highest greenhouse emissions and intermediate economic benefits. Anaerobic digestion is remarkable for its low greenhouse gas emissions, while tannin production is the best-balanced process from both economic and environmental points of view. Pyrolysis is the worst process of all three impacts.

Abstract
Environmental issues and the sustainability of the wine industry receive widespread public attention, but few studies address the environmental impact of the circular wine industry chain. Therefore, we applied the life cycle assessment (LCA) method to a wine enterprise in Inner Mongolia, China, to conduct a cradle-to-gate assessment and comparative analysis on the linear and circular wine industry chain scenarios. The results show that the circular industry chain (S2) has better environmental benefits; the total value of each environmental impact category of S2 is reduced by more than 80% compared with that of the linear industry chain (S1). The global warming potential of S1 is decreased from 4.88 kg CO2eq to 0.919 kg CO2eq for S2. Viticulture is the primary source of environmental problems in all life cycle stages of both scenarios, and electricity and diesel consumption are the key factors affecting the results. Our study shows that the optimization of S2 significantly improves resource efficiency and energy utilization and alleviates the environmental burden through proper waste recycling. Finally, we proposed optimization suggestions based on S2. This study provides scientific guidance for promoting the wine industry to build a circular industry chain and optimize the industrial structure, thus promoting the sustainable development of the industry.

Abstract
When talking about environmental and sustainability topics, the wine sector plays a fundamental role ensuring that wine remains not only economically but also environmentally sustainable, hence the importance of conducting analyses to measure the impact of food production through Life Cycle Assessment tool. This paper aims to propose a systematic review of the LCA studies related to the grape and wine production chain providing both a qualitative and a quantitative analysis of methodologies used, and results proposed, as well as focusing the attention on carbon and water environmental indicators that can be evaluated using the LCA tool. Both the qualitative and the quantitative analysis showed a strong variability among the studies starting from the selection of the functional unit till the way the impact assessment is carried out. The results indicated the lack of homogeneity on the application of the LCA, emphasizing the need for deeper research on the wine sector. Based on the interpretation of the results, it was possible to identify the main drivers and barriers of the environmental impact assessment, allowing the contribution towards providing insights both for LCA practitioners and stakeholders of the wine sector. To this end, the main novelty of this work was to give an all-around view of the application of LCA tool in the wine sector providing a first step in the creation of a standardized procedure that harmonize the way a LCA study must be done. This opportunity would be a huge advantage for the scientific community, allowing the possibility to compare different wine production realities by using a globally recognized procedure without bias. Future research will have to focus on understanding and developing this scheme for enhancing the added value of the wine product.

Abstract
The application of electrodialysis for tartrate stabilization and reagent-free acidity correction of wine and juices is attracting increasing interest. New aliphatic membranes CJMC-3 and CJMA-3 and aromatic membranes CSE and ASE were tested to determine their suitability for use in these electrodialysis processes and to evaluate the fouling of these membranes by wine components for a short (6-8 h) operating time. Using IR spectroscopy, optical indication and measurement of surface contact angles, the chemical composition of the studied membranes, as well as some details about their fouling by wine components, was clarified. The current-voltage charsacteristics, conductivity and water-splitting capacity of the membranes before and after electrodialysis were analyzed. We found that in the case of cation-exchange membranes, complexes of anthocyanins with metal ions penetrate into the bulk (CJMC-3) or are localized on the surface (CSE), depending on the degree of crosslinking of the polymer matrix. Adsorption of wine components by the surface of anion-exchange membranes CJMA-3 and ASE causes an increase in water splitting. Despite fouling under identical conditions of electrodialysis, membrane pair CJMC-3 and CJMA-3 provided 18 ± 1 tartrate recovery with 31 · 10-3 energy consumption, whereas CSE and ASE provided 20 ± 1% tartrate recovery with an energy consumption of 28 · 10-3 Wh, in addition to reducing the conductivity of wine by 20 ± 1%. The casting of aliphatic polyelectrolyte films on the surface of aromatic membranes reduces fouling with a relatively small increase in energy consumption and approximately the same degree of tartrate recovery compared to pristine CSE and ASE.

Abstract
The wine industry is one of the most relevant socio-economic activities in Europe. However, this industry represents a growing problem with negative effects on the environment since it produces large quantities of residues that need appropriate valorization or management. From the perspective of biorefinery and circular economy, the winery residues show high potential to be used for the formulation of new products. Due to the substantial quantities of phenolic compounds, flavonoids, and anthocyanins with high antioxidant potential in their matrix, these residues can be exploited by extracting bioactive compounds before using the remaining biomass for energy purposes or for producing fertilizers. Currently, there is an emphasis on the use of new and greener technologies in order to recover bioactive molecules from solid and liquid winery residues. Once the bio compounds are recovered, the remaining residues can be used for the production of energy through bioprocesses (biogas, bioethanol, bio-oil), thermal processes (pyrolysis, gasification combustion), or biofertilizers (compost), according to the biorefinery concept. This review mainly focuses on the discussion of the feasibility of the application of the biorefinery concept for winery residues. The transition from the lab-scale to the industrial-scale of the different technologies is still lacking and urgent in this sector.

Environmental Impacts of Organic and Biodynamic Wine Produced in Northeast Italy. SUSTAINABILITY 2022. [DOI: 10.3390/su14106281] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Indexed: 12/04/2022]
Abstract
Increasing awareness of sustainability in the agri-food sector is leading to a gradual transition toward lower-impact farming systems, such as organic and biodynamic farming. The environmental performance of organic wines has largely been compared to that of conventional wines, and few researchers have investigated the differences between organic and biodynamic wine production from an environmental point of view. Therefore, in this study, the environmental profiles of two organic and two biodynamic wines produced in two areas in Northeast Italy were assessed by performing a “cradle-to-gate” analysis according to the life-cycle assessment (LCA) methodology. Results were used both to compare organic and biodynamic vitiviniculture and to draw overall conclusions on the environmental performance of each of the analyzed wines in order to identify environmental hotspots and provide recommendations to stakeholders. Production of the glass bottles was identified as the main source of environmental burden in all four systems, followed either by the production and use of fertilizers and pesticides, or the use of agricultural machinery. Results also showed that biodynamic wines seem to be responsible for lesser environmental impacts than organic ones.

Abstract
This study presents techno-economic evaluation and life cycle assessment of a novel biorefinery using the three main waste streams generated by wineries for the production of bio-based succinic acid (SA), crude phenolic-rich extract, grape-seed oil, calcium tartrate and crude tannin-rich extract. Process design has been employed for the estimation of material and energy balances and the sizing of unit operations. The Minimum Selling Price of succinic acid production within a winery waste biorefinery ranges from $1.23-2.76/kgSA depending on the market price and the potential end-uses of the extracted fractions. The Global Warming Potential and the Abiotic Depletion Potential of winery waste valorisation through the proposed biorefinery are 1.47 kg CO2-eq per kg dry waste and 25.2 MJ per kg dry waste, respectively. Biorefining of winery waste could lead to the development of a sustainable and novel bioeconomy business model with new market opportunities and efficient waste management.

[PMID: 34844320 DOI: 10.1016/j.scitotenv.2021.150312] [Citation(s) in RCA: 18] [Impact Index Per Article: 9.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/23/2021] [Revised: 09/07/2021] [Accepted: 09/09/2021] [Indexed: 06/13/2023]
Abstract
The single bioprocess approach has certain limitations in terms of process efficiency, product synthesis, and effective resource utilization. Integrated or combined bioprocessing maximizes resource recovery and creates a novel platform to establish sustainable biorefineries. Anaerobic fermentation (AF) is a well-established process for the transformation of organic waste into biogas; conversely, biogas CO2 separation is a challenging and expensive process. Biological fixation of CO2 for succinic acid (SA) mitigates CO2 separation issues and produces commercially important renewable chemicals. Additionally, utilizing digestate rich in volatile fatty acid (VFA) to produce medium-chain fatty acids (MCFAs) creates a novel integrated platform by utilizing residual organic metabolites. The present review encapsulates the advantages and limitations of AF along with biogas CO2 fixation for SA and digestate rich in VFA utilization for MCFA in a closed-loop approach. Biomethane and biohydrogen processes CO2 utilization for SA production is cohesively deliberated along with the role of biohydrogen as an alternative reducing agent to augment SA yields. Similarly, MCFA production using VFA as a substrate and functional role of electron donors namely ethanol, lactate, and hydrogen are comprehensively discussed. A road map to establish the fermentative biorefinery approach in the framework of AF integrated sustainable bioprocess development is deliberated along with limitations and factors influencing for techno-economic analysis. The discussed integrated approach significantly contributes to promote the circular bioeconomy by establishing carbon-neutral processes in accord with sustainable development goals.

Talwar N, Holden NM. The limitations of bioeconomy LCA studies for understanding the transition to sustainable bioeconomy. THE INTERNATIONAL JOURNAL OF LIFE CYCLE ASSESSMENT 2022; 27:680-703. [PMID: 35600742 PMCID: PMC9114090 DOI: 10.1007/s11367-022-02053-w] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/12/2021] [Accepted: 04/07/2022] [Indexed: 05/05/2023]
Abstract
PURPOSE Transition to bioeconomy requires all actors and stakeholders to measure the impact of systems that use bioresources and technologies to provision society. There are however some challenges with integrating LCA into business development and management, which have important implications for bioeconomy. There have been many LCA studies published in the twenty-first century, but the question must be answered: how useful are these LCA studies to help understand and manage transition to sustainable bioeconomy? METHOD This research used a structured literature review to identify 83 bioeconomy LCA studies published from January 2006 to June 2021 (excluding bioenergy). The studies were analysed for compliance with the ISO 14044 standard, with specific reference to the goal, commissioning perspective, system boundary, function and functional unit, impact methods and categories. RESULTS AND DISCUSSIONS It was found that more than 85% of the studies reviewed failed to present the required goal statement and a description of the function of the system. Nearly 13% of the studies did not define the system boundary, and only 17% included a full life cycle including raw material extraction, production, use and end-of-life stages. The majority of the LCA studies surveyed from 2006 to 2021 were either (i) not in compliance with the ISO standards or (ii) space and style limitations of the publication process prevented competent practitioners from properly conveying their work. This suggests that the value and integrity of the literature are undermined by not rigorously addressing the first and most important stage of an LCA study. CONCLUSION When interpreting the results, a major shortcoming noted was that most studies did not consider the industrial symbiosis needed between feedstock, technology, primary products, side streams, downstream valorisation and long-term circularity in order to properly understand the transition pathways required. Bioeconomy technologies were imagined as displacers for feedstocks and processes to adapt business as usual, rather than as transformers of the system to a sustainable footing. RECOMMENDATION If LCA studies are going to provide meaningful information for actors and stakeholders to assess whether a system will be able to operate sustainably, studies should include a full, integrated system, standards should be adhered to and approaches should perhaps go beyond mere eco-efficiency, or doing less harm, as these are not necessarily indicative of sustainability. Historical bioeconomy LCA studies do not provide great insight into the transition to sustainable bioeconomy.

The Dutch Green Deals Policy and Its Applicability to Circular Economy Policies. SUSTAINABILITY 2021. [DOI: 10.3390/su132111683] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Indexed: 12/31/2022]
Abstract
This study investigates the applicability of the Dutch Green Deals policy instrument for use in projects that help the transition towards a Circular Economy in the Netherlands. Green Deals provide an opportunity for firms, NGOs, universities, and provincial, municipal, or waterboard governments to sign an agreement with the national government to take away barriers for a Circular Economy related innovation. Quantitative and qualitative content analysis has been performed, categorizing all green deals as being related to Circular Economy and those are further categorized thematically and analytically. A total of 50 relevant Green Deal agreements are selected for quantitative and qualitative content analyses that cover 9 themes, 20 industry classifications, and 10 types of action undertaken, being particularly popular in the biobased economy and construction industry. The policy instrument is believed to be successful in addressing a variety of barriers and as useful in strengthening national innovation systems, thus, it can be recommended for application in other countries. The instrument does lack clear policy indicators and would benefit from explanatory reviews with each agreement. Future research could compare this policy instrument to similar instruments employed in other EU countries and developing countries, the potential role of green financing for such green deal agreements should also be considered.
