The agronomic performance of rotary drum compost (RDC), particularly across a complete compost incorporation gradient, remains insufficiently documented. This study evaluated the maturity and physicochemical quality of RDC produced from household organic waste and assessed its effects on the germination and early growth of <i>Solanum lycopersicum</i> cultivated in six compost–soil mixtures containing 0, 20, 40, 60, 80, and 100% RDC. Compost maturity was confirmed by a germination index of 87%, a low NH₄⁺/NO₃⁻ ratio, and a favorable nutrient composition. Compost incorporation significantly enhanced all plant performance indicators (<i>p</i> &lt; 0.001), increasing germination from 10.0% in the control to 86.7% at 100% RDC, while shoot growth, root development, biomass accumulation, and vigor improved markedly. Large effect sizes (partial η² = 0.72–0.98) indicated that compost dose explained most of the observed biological variation. Strong positive correlations were observed between substrate fertility parameters and plant responses (<i>r</i> &gt; 0.80). Quadratic dose–response models provided the best fit (R² up to 0.958), revealing accelerated growth responses without evidence of saturation. Principal component analysis (PCA) showed that the compost incorporation gradient accounted for 89.6% of total multivariate variation. These findings demonstrate the strong agronomic potential of mature RDC as a high-value organic amendment for enhancing tomato seedling establishment under greenhouse conditions and provide a scientific basis for future field validation in semi-arid agricultural systems.</p></div>","PeriodicalId":643,"journal":{"name":"Journal of Material Cycles and Waste Management","volume":"28 5","pages":"4538 - 4557"},"PeriodicalIF":3.8,"publicationDate":"2026-08-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148981293","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A systematic review of biorefinery frameworks for agricultural waste (corn stover, sugarcane bagasse, wheat straw, and rice straw) in the circular bioeconomy is presented. The initial literature search across Google Scholar, ScienceDirect, and Web of Science (2011–2025) yielded 113,221 documents, of which 14 peer-reviewed studies were selected based on strict inclusion criteria and underwent a detailed synthesis. The reviewed studies show that an integrated biorefinery can produce 3–5 value-added products from a single feedstock (bioethanol, biogas, biochar, and platform chemicals). Reported greenhouse gas reduction benefits, however, are very sensitive to methodology choice, such as allocation method (economic: 67–72%; substitution: 85–90%), system boundaries (cradle-to-gate vs. cradle-to-grave), biogenic carbon accounting (dynamic accounting reduces reported reductions by 5–10%) and geographic grid carbon intensity (coal-dependent grids: 55–70%; low-carbon grids: &gt;80%). There is significant variation in Geographic synthesis: Brazil reduces GHGs between 80 and 90% (∼110 g CO₂/kWh grid), while India and China reduce GHGs between 55 and 65% (∼525–670 g CO₂/kWh grid). Major challenges to scaling up include the lack of established LCA methodologies for agro-waste systems, the under-representation of indirect impacts (land-use change, changes in soil organic carbon), data limitations at local scales, and the maximum sustainable removal rates of residues (50–60%). Based on this review, the potential for agricultural waste biorefineries to reduce GHG emissions is high, but the benefits reported are dependent on the methodology and geographically variable. To promote the circular bioeconomy, a universal approach to LCA, regulatory support at the regional level and investment in economic and social aspects are key.</p></div>","PeriodicalId":643,"journal":{"name":"Journal of Material Cycles and Waste Management","volume":"28 5","pages":"3983 - 4003"},"PeriodicalIF":3.8,"publicationDate":"2026-08-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148981322","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Geopolymers offer a sustainable, low-carbon solution, especially when using industrial by-products. In this study, geopolymer mortars based on ground granulated blast furnace slag (GGBFS) and cenospheres were developed to incorporate plastic e-waste as a partial replacement for natural river sand. An optimized binder composed of 50% GGBFS and 50% cenospheres was used as the reference system. E-waste aggregates were introduced at volumetric replacement levels of 10%, 20%, and 30%. To improve matrix quality and compensate for strength loss, nano silica was added at dosages of 1%–3%. Fresh properties, mechanical performance, and durability-related indicators were evaluated using both destructive and nondestructive testing methods. These included compressive strength, ultrasonic pulse velocity, water absorption, and electrical resistivity. The results show that e-waste aggregates reduce density but negatively affect strength and durability at higher replacement levels. Nano silica significantly improves matrix densification and interfacial bonding, leading to better mechanical performance and durability. Among all mixtures, 20% e-waste aggregate combined with 2% nano silica provided the best balance between strength, durability, and workability, achieving a compressive strength of ≥ 40 MPa and flexural strength of ≥ 5 MPa at 28 days. The use of e-waste aggregates and nano silica in GGBFS-cenosphere geopolymers provides a balanced solution for waste utilization and material performance, highlighting the potential for valorizing electronic waste within sustainable construction materials.</p></div>","PeriodicalId":643,"journal":{"name":"Journal of Material Cycles and Waste Management","volume":"28 5","pages":"4523 - 4537"},"PeriodicalIF":3.8,"publicationDate":"2026-08-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148981315","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Based on the 7th population census (2023), country generates approximately 3.2 million tons (Mt) of plastic waste annually which is projected to reach 4.79 Mt by 2050 at a 1.5% annual growth rate. Due to the limited infrastructure for collection, treatment, and recycling, around 85% of the plastic waste remains mismanaged in urban areas and 100% in rural regions. An estimated 200,000-333,000 waste scavengers serve as the primary recovery mechanism within the informal sector. This study adopts a bottom-up methodology to estimate the plastic waste using the waste amount characterization studies (WACS) from 14 cities. Moreover, assessment of trade, recycling potential, and regulatory frameworks were also discussed. Pakistan imported plastic waste worth of USD 18.77 million in 2024, mainly from the United Kingdom, United Arab Emirates, and the United States. These imports constitute approximately 1.4% of domestic generation showing that the accumulation is largely driven by domestic consumption and inadequate end-of-life management. The analysis distinguishes two policy failure levels. Pakistan has had federal and provincial laws and single-use plastic bans since 1997. The second binding constraint is implementation, with six gaps: no operational Extended Producer Responsibility (EPR) system, unharmonized federal and provincial mandates, non-recognition of the informal recovery sector, no collection and recycling infrastructure, weak customs enforcement of Basel-aligned import controls, and no national data Each gap is addressed by enforcement budgets, inter-provincial coordination, waste picker integration, and national monitoring.

The system boundaries include the production and transportation of PP granules and packaging materials, as well as the cups’ manufacturing and packaging processes. Three improvement scenarios have been evaluated to reduce environmental impact: replacing PP with polylactic acid (PLA), incorporating renewable energy, and optimizing transportation routes. The results show that the largest environmental burdens come from the production and transport of PP granules, which has a significant impact on resources. Wind energy offers the most reliable reductions among renewable energy sources, and scenario analysis shows that switching to sea-based transportation routes can reduce environmental impacts by up to 45%. Furthermore, using PLA as an alternative raw material to PP significantly reduces toxicity and the use of fossil resources. However, the agricultural inputs required for PLA production contribute to increased eutrophication and acidification.

Four micro-characterization techniques were employed to elucidate hydration mechanisms under varying formulations and curing methods. The results indicate that appropriate incorporation of phosphogypsum under water curing significantly improves compressive strength and fluidity. However, excessive phosphogypsum addition causes expansion, cracking, and substantial strength loss.
