First, ground wheat straw (particle size <20 mm) moisturized (moisture content 70–80 % by weight) by pure water and by FFV were treated with feed grade fungal strains <em>Tramates versicolor</em> (TV) and <em>Pleurotus ostreatus</em> (PO) at 28 °C for six weeks.

Organic acids (over 80 % was lactic acid) accounted for 9–10 % dry matter of the substrates and lowered pH from 5 to about 3.5, which is adequate for preservation of the fermented feed. <em>In vitro</em> dry matter digestibility was not different between the standard diet and sustainability-plus diets that contained 10 % or 25 % of the double-fermented circular feed materials.

However, some challenges keep these businesses from switching from a 'take-make-dispose' linear economy to a closed loop with zero waste. In this strand, one such issue is related to the companies’ requirements to understand the level of circularity in their operations. Thus, this paper aims to develop a CE maturity framework for SMEs. The framework draws upon three main phases, encompassing a set of qualitative and quantitative methods. Phase I involves the planning efforts to determine the framework’s audience and scope; Phase II is the development stage concerned with identifying the current state of the art related to CE and developing the theoretical framework for SMEs; Phase III is associated with the framework’s evaluation process, in which an expert panel review was applied to guarantee its robustness and consistency. The work proposes the Circular Economy Maturity Framework (CEMAF), composed of five dimensions: <em>take, make, distribute, use</em> and <em>recover</em>. These dimensions are deployed in sub-dimensions measured with several maturity items and supported by objective evidence. The weighted average of results supported the development of a CE maturity index, enabling companies to benchmark with others. The overall contribution of the research is to introduce a framework for the literature that considers SMEs’ ofter-limited resources, helping practitioners to evaluate and manage CE, and allowing companies to reach higher levels of circularity.</div></div>","PeriodicalId":74689,"journal":{"name":"Resources, conservation & recycling advances","volume":"27 ","pages":"Article 200275"},"PeriodicalIF":5.4,"publicationDate":"2025-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144633507","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}

Biochar, on the other hand, is commonly used for soil enrichment and carbon sequestration, which typically lacks sufficient nutrient content to function as a standalone fertilizer. This review explores an integrated approach to struvite production by incorporating biochar and waste-derived resources, specifically, farm waste (rich in N and P) and industrial wastewater (rich in Mg). Surface-modified Mg-biochar functions both as a Mg source and an effective adsorbent, enhancing nutrient adsorption, struvite crystallization, and retention. The review highlights alternative nutrient sources, Mg-biochar preparation methods, nutrient recovery mechanisms on the biochar surface, and the agronomic potential of biochar-struvite composites. This review supports the principles of a circular economy by transforming waste into value-added, slow-release fertilizers.

To overcome these challenges, the ISRLM tool provides a structured framework for evaluating and visualizing IS readiness, facilitating discussions among actors, creating mutual understanding, and coordinating decision-making. The development of the ISRLM tool followed an iterative process that combined rigorous literature reviews, co-design through stakeholder interviews and workshops, as well as testing and validation within existing IS networks. Drawing on established concepts of readiness level evaluation and incorporating feedback and suggestions of improvement from practitioners and academics, the tool was refined through multiple cycles of testing and evaluation. This co-design approach ensured the tool's relevance and usability across various IS contexts. The ISRLM tool is developed as an interactive Excel-based tool that generates visual outputs based on actors’ evaluation of perceived readiness.

Drawing on semi-structured interviews with housing professionals, cooperative representatives, service providers, and policymakers, we assess the comparative institutional advantages and limitations of cooperatives in enabling circular transitions. Our findings indicate that housing cooperatives can mitigate market failures and overcome split incentives through collective ownership, long-term planning, and participatory governance. These features help facilitate lifecycle-based investments, bundled procurement, and shared infrastructure. However, cooperatives also face key challenges, including complex decision-making, limited access to finance, and regulatory barriers. This paper contributes to the understanding of alternative housing models for urban sustainability by offering insights into how cooperative-led initiatives can support circular innovation.
