Guided by PRISMA procedures, the review synthesizes evidence from 121 peer-reviewed and grey literature sources published between 2013 and 2024. Current waste generation in major urban centers Nairobi, Addis Ababa, Kampala, and Dar es Salaam ranges from 0.45 to 0.85 kg per capita per day and is projected to rise by 60-70% by 2030 if prevailing trends continue, underscoring the urgent need for systemic intervention. Emerging CE practices, including composting, plastic recycling, and waste-to-energy initiatives, demonstrate growing momentum across Kenya, Uganda, Tanzania, and Ethiopia. However, their widespread adoption remains constrained by infrastructural deficiencies, limited financing, weak regulatory enforcement, and insufficient technical capacity. Despite these challenges, successful models such as community-driven recycling in Nairobi, decentralized composting schemes, and the Reppie waste-to-energy facility in Addis Ababa highlight the transformative potential of localized innovation, inclusive governance, and multi-stakeholder collaboration. The review identifies four primary enablers for CE acceleration: robust and enforceable policy frameworks, technologically adaptable waste systems, targeted capacity building, and strong public–private partnerships. This study concludes that embedding circular economy principles into East African urban governance offers a viable pathway to reducing pollution, strengthening resource efficiency, generating green jobs, and fostering resilient, sustainable cities. The study recommends introducing fiscal instruments, formalizing and supporting the informal waste sector, and establishing regional knowledge-sharing platforms to harmonize standards and scale best practices.</div></div>","PeriodicalId":100960,"journal":{"name":"Next Sustainability","volume":"7 ","pages":"Article 100228"},"PeriodicalIF":0.0,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145799949","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}

A unified translation framework is proposed that links in-silico ranking to statistically efficient experimentation, mechanistic validation, recyclability, and product quality checks, and regulatory readiness through standardized reporting of composition, physicochemical properties, and safety endpoints.

The correlation between their size, represented by the installed capacity, and their performance is a research area that has been insufficiently explored in the literature. Accordingly, this paper assesses the impact of the CSP plants’ size on their energy and economic performances. For this purpose, the performance of thirteen CSP plants, distributed over four regions, namely China, Morocco, South Africa and United States of America, is assessed using several key indicators based on experimental data. Additionally, several numerical simulations are performed by means of System Advisor Model software. The results show that the larger the CSP plant’s size, the higher the capacity factor. However, under specific conditions, small-size CSP plants achieve similar annual electricity production levels as medium-size ones. From an economic point of view, it is asserted that the levelized cost of energy of the studied CSP plants decreases with the increase of their sizes. Hence, this work constitutes a theoretical and practical reference to concretize the impact of CSP plants’ size on their cost-effectiveness and also to shed light on the possible optimization scenarios related to the CSP plants’ size.</div></div>","PeriodicalId":100960,"journal":{"name":"Next Sustainability","volume":"6 ","pages":"Article 100143"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144254112","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}

This has hindered the development of policies to enhance sustainability of wood resources. To provide insights into CEPs implementation in the wood products value chains, a cross-sectional research design was adapted to describe and analyze awareness, existing practices and perceived adoption of CEPs using the 10 R model and following the value chain framework. Mufindi district in Tanzania was purposively selected due to presence of various small and large-scale wood products value chains. A survey involving random selection of 110 small-scale enterprises and selection of eight (8) large-scale wood products enterprises was done based on the type of wood products manufactured. Data was collected by using a semi-structured questionnaire, a checklist for key informants’ interview and through direct observation. Analysis involved application of the 10 R model to identify and characterize existing CEPs in the wood products value chains. Level of CEPs adoption was estimated as average of chain actors perceived CEPs adoption score. Results indicated seven CEPs implemented at distinct levels in the wood products value chains, specifically, refuse, rethink, reduce, repurpose, reuse, recycle and recover.

The synthesis of the GNs from plastic waste was done as we previously reported in the steps of the pyrolytic process, where the copper turnings are used as catalytic templates in the present study. Because of the excellent catalytic efficiency towards breaking old carbon-carbon bonds and forming new carbon-carbon bonds, the copper turnings act as an excellent degradation catalyst and promote the growth of graphitic skeletons and, consequently, graphene nanosheets. The synthesized GNs showed a high conductivity of ∼ 1730 S/m. GNs thus synthesized is implemented for synthesizing GNs/polypyrrole nanocomposites, which is later investigated for the TE applications. The values of the Seebeck coefficient showed that the composite of GNs/polypyrrole performs as a p-type semiconductor. The TE figure of merit (ZT) for GNs/polypyrrole demonstrated good thermoelectric characteristics and showed a value of 3.75 × 10<sup>−6</sup> at the temperature.
