Multiple projections suggest the food demand for animal products to increase further by 35% by 2050 and thus the urgency for substituting alternative proteins to, at least, animal proteins. In this study, we examine GHG emissions from the production and consumption of conventional and alternative proteins. The prime focus of the study is to quantify the achievable GHG reduction through protein-to-protein substitution from conventional to alternative sources. It aims to compare the emission impacts of protein-equivalent substitution across eight conventional and six alternative protein sources through three regions—India, the United Kingdom, and the European Union—over a 30-year average. Among the conventional sources, beef-veal and sheep meat were found to be the top contributors to GHG emissions across the panel. Comparing emissions with respect to the possible switch between given alternatives to conventionals, overall, our results suggest pulses and chickpeas to be the best alternative substitutes for beef-veal and sheep meat to achieve substantial emission reduction in the three regions. Moreover, significant variations in emission reductions from substitutions seem to emerge at both production and consumption levels.</div></div>","PeriodicalId":100250,"journal":{"name":"Cleaner and Circular Bioeconomy","volume":"12 ","pages":"Article 100174"},"PeriodicalIF":0.0,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144880117","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To evaluate the effects of these amendments, a screenhouse experiment was conducted to assess the impact of biodigestate, poultry manure, and NPK fertilizer on soil chemical properties, as well as the growth, yield, and mineral composition of okra (<em>Abelmoschus esculentus</em> L. Moench) and cucumber (<em>Cucumis sativus</em> L.). The study included seven treatments: biodigestate (BD), poultry manure (PM), NPK 15–15–15 fertilizer (NPK), biodigestate + poultry manure (BD+PM), biodigestate + NPK fertilizer (BD+NPK), NPK fertilizer + poultry manure (NPK+PM), and a control with no amendments. The experimental layout followed a completely randomized design (CRD) with three replications. The okra and cucumber trials were conducted simultaneously in adjacent sections of the same screenhouse. Amendments were applied at a rate of 120 kg N ha⁻¹. Findings indicated that the application of BD, PM, or NPK—either individually or in combination—significantly enhanced soil chemical properties, plant growth, yield, and mineral composition of both crops compared to the control. NPK, PM, and BD increased the fruit weight of cucumber and okra by 100.0% and 50.0%, 240.0% and 150.0%, and 196.7% and 103.3%, respectively, relative to the control. Among the sole applications, PM demonstrated the most substantial improvements in soil fertility and crop performance compared to BD and NPK. Compared to NPK and BD, PM increased the yield of cucumber and okra by 67.2% and 66.7%, and 14.0% and 25.0 %, respectively. Additionally, the combination of NPK+PM (1.49 kg of cucumber and 0.12 kg of okra) resulted in better soil properties, growth, and yield than BD+NPK (0.74 kg of cucumber and 0.07 kg of okra). However, BD+PM (1.42 kg of cucumber and 0.12 kg of okra) performed comparably to NPK+PM, while exhibiting the highest nutrient composition in both okra and cucumber fruits. The BD+PM combination offers a viable alternative to NPK+PM, achieving similar yields while improving okra and cucumber nutrient content. The novelty of this study lies in its dual-crop, side-by-side assessment of BD-based nutrient management strategies under controlled conditions—a methodological approach not widely adopted in previous research. By simultaneously evaluating BD interactions with both organic and inorganic sources across two fruit vegetables, this work provides new evidence supporting BD+PM as a viable and sustainable alternative to conventional NPK-based fertilization. Future research should investigate the effects of these amendments on fruit quality attributes such as taste, shelf life, and nutrient stability.</div></div>","PeriodicalId":100250,"journal":{"name":"Cleaner and Circular Bioeconomy","volume":"12 ","pages":"Article 100192"},"PeriodicalIF":0.0,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145617477","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address this the literature gap, the present study sought to identify and categorize young individuals in Indonesia into more homogenous groups based on socio-demographic characteristics and food wasting behavior. To this end, Principal Component Analysis (PCA) and Cluster Analysis (CA) were employed. The data were collected through an online survey of young individuals aged 16–30 across Indonesia as respondents, resulting in a total of 481 respondents. The study’s finding indicate that the combination PCA and CA is a viable approach for the identification and clustering of young individuals in Indonesia, with the basis of the identification and clustering being their socio-demographic characteristics and their behavior concerning food waste. This study underscores the heterogeneity among young Indonesians with regard to their food wasting behavior and socio-demographic characteristics. The analysis yielded three distinct clusters: Cluster 1, \"students who care about food waste\", Cluster 2, \"students who do not care about food waste\", and Cluster 3 \"young workers who care enough about food waste\". Specifically, no significant differences were found between clusters with regard to gender and the predominant method of food provisioning. A comparison of clusters reveals significant differences in the variables of age, educational attainment, occupation, income, food expenditure, and the frequency of food wastage. The differences among clusters provide crucial insights to support initiatives aimed at curbing food waste by addressing issues of heterogeneity. The distinguishing characteristics of clusters in the younger generation require alternative strategies and distinct policy recommendations, as outlined in this study.</div></div>","PeriodicalId":100250,"journal":{"name":"Cleaner and Circular Bioeconomy","volume":"12 ","pages":"Article 100165"},"PeriodicalIF":0.0,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144611539","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In more agriculturally advanced areas, emissions are reduced, showing an inverted U-shaped relationship between agriculture and carbon emissions in the eastern and central regions. In contrast, the western and central areas still faced potential increases in emissions. Additionally, agricultural progress has a significant spatial dimension on carbon emissions. In the short term, neighboring regions contribute considerably more carbon emissions than local agriculture. However, advancements in agriculture reduced emissions in nearby areas over time, and long-term agricultural progress has greatly reduced carbon emissions in surrounding regions. Although exploring strategies can help reduce emissions in agricultural settings, the reductions achieved through these approaches only partially offset the overall carbon emissions resulting from agricultural progress.

The adoption of circular supply chains has been found to improve the economic and environmental outcomes of production processes. The use of agricultural and food byproducts, such as hydrolyzed soymeal, as a source of amino acids has been identified as a way to reduce cost and environmental impacts.

This study explores the combined effects of pretreating old corrugated container (OCC) pulp, a type of recycled fiber, with surfactants and optimizing drying conditions to enhance dewatering efficiency and mechanical properties of packaging grades. Two surfactants- cetyltrimethylammonium bromide (CTAB), a cationic surfactant, and alcohol ethoxylate (NS), a non-ionic surfactant were employed for the recycled fiber modification. Packaging handsheets were prepared under various drying conditions, and their surface morphology and cross-sectional structure were characterized using scanning electron microscopy (SEM). The degree of chemical interactions in surfactant-fiber systems were evaluated using X-ray photoelectron spectroscopy (XPS) and time-of-flight secondary ion mass spectrometry (ToF-SIMS). Surfactant treatment effectively reduced surface tension to ∼47 mN/m, facilitating lower pulling forces, improved fiber dispersion and enhanced dewatering, with a drainage rate increase of 1.56-fold and reductions in hard-to-remove water (HRW) and water retention value (WRV) by ∼49 % and ∼13 %, respectively.

Somalia has maintained its position as the leading banana producer in East Africa for over a century, but the market stalled due to the 1991 civil war. This study aims to examine the impact of climatic and non-climatic factors on Banana production in Somalia through modeling and projection. The study used 63-year annual time series data from secondary sources from the FAO Centre and the World Bank. It used Vector Autoregressive and Autoregressive Distributive Lag models to analyse variables' stationary behaviour. Unit root tests were applied, and the optimal lag order was determined using minimizing information criteria or maximizing log-likelihood. Results showed that most variables became stationary after the first difference, except for CO2 emissions and urban population. The researcher recommends using an autoregressive disturbed lag model instead of a Vector Autoregressive model. Long-term, temperature and political stability have a significant positive impact on the dependent variable. At the same time, rainfall, CO2 emissions, land under cereal, and urban population are not statistically significant predictors in the short run. The study confirms a long-term equilibrium connection between climate variables, non-climate variables, and agricultural output.
