This paper studied management of this waste stream in the concept of urban mining and circular economy through composting and reuse the produced compost for different purposes as an indicator for the circular economy through the period extended from 2021 up to 2035. Two compost reuse scenarios are studied: use for agricultural purposes, and use as landfill cover materials. For agricultural purposes, compost can be used as an alternative fertilizer where nutrients in compost can replace the existing chemical fertilizers available in Palestine such as humic acid as a source of carbon, Ammonium Sulphate as a source of nitrogen, Triple Super Phosphate as a source of Phosphorus, and Potassium Phosphate source of Potassium. The estimated revenue from compost use in agriculture is USD 194.8 million in 2021 and USD 369.8 million in 2035. The estimated saving from using compost as landfill cover is USD 0.876 million annually, and USD 13.14 million during the 15 years’ study period. Implementation of the circular economy principles in municipal solid waste management through composting can close the materials recycling loop, generating extra income, and adding net revenue to the national economy. </p></div>","PeriodicalId":643,"journal":{"name":"Journal of Material Cycles and Waste Management","volume":"26 5","pages":"2980 - 2995"},"PeriodicalIF":2.7,"publicationDate":"2024-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10163-024-02018-1.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141566696","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Results show that while mechanical properties are preserved with up to 10% cement replacement, environmental impact reductions require 20–40% cement replacement, where the higher the concrete compressive strength, the higher the relative environmental benefits. For concrete mixtures produced with 40% red ceramic waste, the environmental load of C45, C40, and C35 are compatible and lower than that of plain C30. Due to the increasing amount of superplasticizer required to guarantee concrete workability, the environmental benefits of using red ceramic waste are slightly less evident for human toxicity than for other impact categories.

As a low-cost and renewable agro-industrial substrate, garlic straw holds significant potential for bioethanol production. To optimize the enzymatic conversion, pretreatment was performed to facilitate the enzymatic saccharification process by alkaline peroxide and sodium chlorite, resulting in a substrate consisting of 83.07% cellulose, 6.13% hemicelluloses, and 2.09% lignin. The bleached garlic straw (BGS) was hydrolyzed using a cellulolytic complex produced by the hypercellulosic mutant <i>Penicillium occitanis</i> Pol6, aiming to convert cellulose into glucose. The BGS was treated with various enzyme loading (10–50 FPU/g), at different BGS concentration (20–80 g/L) and tween 80 concentration (0–8 g/L) and at different reaction time (24–72 h). The hydrolysis yield from enzymatic saccharification of BGS were evaluated using a Box–Behnken Design. The optimum conditions for the hydrolysis yield were obtained based on surface and contour plots. The maximum predicted hydrolysis yield of 54.08% was obtained as follows: enzyme loading 40 FPU/g, BGS concentration 22 g/L, Tween 80 concentration 6 g/L and hydrolysis time 72 h. Fermentation of hydrolysates of bleached garlic straw (HBGS) carried out using <i>Saccharomyces cerevisiae</i> for 24 h showed that the sugar content decreased over time, while ethanol production increased. Besides, the highest bioethanol production (11.9 g/L) was observed in the 4% HBGS sample after 6 h of alcoholic fermentation.
