The technologies are categorized based on their products: biofuels (solid, gaseous, and liquid) and functional products (carbon fertilizer, activated carbon, platform molecular compounds). Various treatment methods, including pyrolysis, anaerobic digestion (AD), hydrothermal liquefaction (HTL), gasification, and composting, are assessed for their conversion efficiency, energy requirements, environmental impacts, and economic viability. While biofuel production offers significant benefits, the processes are often energy-intensive and require precise control to minimize environmental impacts. Similarly, the conversion into functional products demands rigorous management to ensure product consistency and safety, particularly concerning antibiotic residues and ARGs.

And the surface temperature of OPCM rose rapidly from 25°C to 76.2°C within 1 min under the simulated sunlight irradiation of 1.0 kW/m<sup>2</sup>. Furthermore, three kinds of heavy oils with viscosities of 44204 mPa·s, 9373 mPa·s, and 3671 mPa·s were selected for the absorption test. The test indicated that the maximum absorption capacities of OPCM for these oils were 126 g oil/g OPCM, 117 g oil/g OPCM, and 114 g oil/g OPCM, respectively. At the same time, from the perspective of circular economy, after 11 cycles of oil absorption, the absorption capacities of OPCM remained at 107 g oil/g OPCM, 102 g oil/g OPCM, and 100 g oil/g OPCM. Because of the photothermal conversion property and thermal conductivity of OPCM, the viscosity of heavy oil decreased and the fluidity increased. Additionally, the capillary force and hydrophobic interaction improved the absorption efficiency of OPCM for heavy oil. The sponges OPCM are potentially useful for in addressing oil spills and environmental issues during crude oil production and transportation.</div></div>","PeriodicalId":15759,"journal":{"name":"Journal of Environmental Chemical Engineering","volume":"13 3","pages":"Article 116195"},"PeriodicalIF":7.4,"publicationDate":"2025-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143687329","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
