The literature has explored food waste from many perspectives; however, no attention has been devoted to understanding how the intrinsic characteristics of food products influence food waste generation and valorization. This study proposes a classification of food products based on circular economy principles derived from a systematic literature review. The classification sheds light on how the intrinsic variability of food products influences food waste generation and recovery along the supply chain. The characteristics that drive differences in terms of food waste are identified by defining two product groups for each step of the chain (primary production: plant origin and animal origin; manufacturing: minimally processed and processed; distribution: ambient temperature and controlled temperature; retail: short shelf life and long shelf life). This stresses the intertwining of food waste with supply chain operations. Moreover, within the same supply chain stage, food waste causes and circular economy actions vary greatly depending on the product characteristics. The review also reveals how the most relevant causes within each product category correspond to a high relevance of practices addressing these causes. The adopted perspective represents a novel contribution to knowledge, providing a clear discussion of the variability of food waste along the supply chain and unveiling aspects requiring further research. From a practical standpoint, the classification can empower food industry actors to develop circular economy actions through an appropriate understanding of product characteristics.</p></div>","PeriodicalId":74689,"journal":{"name":"Resources, conservation & recycling advances","volume":"23 ","pages":"Article 200229"},"PeriodicalIF":5.4,"publicationDate":"2024-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2667378924000282/pdfft?md5=4d4d827882391e426f59b4ccae899a40&pid=1-s2.0-S2667378924000282-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142148505","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, we present a closed-loop methodological framework built on machine learning and robust mathematical optimization technique, that offers the mathematical rigour, to determine the optimum operating conditions for the maximum Cu and Ni recovery from the WPCB. Alkali leaching based novel metals recovery process from the WPCB is designed, and the experiments are conducted to collect the data on the percentage recovery of Cu and Ni against the operating levels of the process input variables (ammonia concentration (NH₃ conc.

The experimental data is deployed to construct the functional mapping between the nonlinear output variables of metals recovery process with the hyperdimensional input space through artificial neural network (ANN) based modelling algorithm – a powerful universal function approximator. Well-predictive ANN models for Cu and Ni recovery are developed having co-efficient of determination (R²) value more than 0.90. Partial derivative-based sensitivity analysis is then carried out to establish the order of the significance of the input variables that is backed by the domain knowledge, thus promotes the interpretability of the trained ANN models. The hybridization of ANN with NLP (nonlinear programming) framework is implemented for the determination of optimized operating conditions to extract maximum Cu and Ni under separate and combined model of metal extraction. The robustness of the determined solutions is verified, the determined optimized solutions for the metal recovery are validated in the lab, and the maximum metal recovery, i.e., 100 % Cu and 90 % Ni is extracted from the WPCB.

Purpose was to identify a direction for mining tailings usage based on the circular waste management. The novelty of the author's approach lies in regulation of mechanical treatment of slag to optimize the backfill composition. The methodology involved a study of mining waste (slag) obtained from major (eight) metallurgical plants in Russia. For mathematical processing primary data, smoothing and deterministic three-dimensional interpolation methods were used. As a result, for the first time it has been established that the ultimate uniaxial compressive strength after mechanical treatment of slag increases by logarithmic laws. As the curing time increases from 10 days to 90 days (with the addition of Ca or Si) the strength increases by 21 % (7 % and 23 %). The possibility of completely replacing the traditional cement binder with metallurgical slag in the backfill composite has been proven. It has been established that the use of activation treatment (both mechanical and chemical) makes it possible to increase the strength characteristics of backfill samples after their curing. The principle of organizing mining production has been implemented, which provides for the use of intermediate products (blast furnace granulated slag), previously classified as technogenic waste, in a closed production cycle. The introduction of this principle will eliminate (minimize) the formation of man-made waste. The scientific merit of replacing traditional cement binder with technogenic waste (blast furnace granulated slag) allows implementation of circular economy in mining.</p></div>","PeriodicalId":74689,"journal":{"name":"Resources, conservation & recycling advances","volume":"23 ","pages":"Article 200224"},"PeriodicalIF":5.4,"publicationDate":"2024-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2667378924000233/pdfft?md5=41920a7a4eaec89d862aef6b16805dc8&pid=1-s2.0-S2667378924000233-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141539788","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This review analyzes 107 scientific papers and reports to explore the opportunities to integrate a circular economy (CE) within the aviation sector, emphasizing on waste management and circular aviation practices. It highlights the sector's initiatives on in-cabin waste reduction, waste tracking systems, and plastic-free flights.
