Owing to its complex chemical framework, PU is highly recalcitrant. This plastic type consists of hard and soft segments in its structure, which critically influence its mechanical properties and functional versatility. Its inherent structural complexity and resistance to degradation have created significant challenges in its end-of-life management, contributing to persistent plastic pollution. In recent years, microbial-mediated enzymatic degradation has emerged as a promising alternative to conventional waste treatment and disposal strategies. This review provides a comprehensive overview of PU biodegradation, outlining the polymer's chemistry, the role of microbial communities and their associated enzymes, and emerging insights from metabolic pathway analysis to molecular-based metagenomic studies. Standardized testing methods and analytical techniques are evaluated along with physicochemical and environmental factors that influence degradation. Recent innovations like the development of engineered microbial consortia, enzyme optimization strategies, pre-treatment methods, and bio-based formulations collectively advance PU biodegradation and support sustainable material valorisation. In silico approaches, such as machine learning and computational studies, are highlighted for their potential to predict degradation efficiency and guide experimental design.

The reliance on environmentally hazardous synthetic oilfield chemicals contributes to severe global issues, including carbon emissions, global warming, and climate change, posing potential threats. Therefore, ongoing research is increasingly directed toward the development of oilfield chemicals derived from natural sources, particularly plant-based extracts—an approach commonly known as \"green oilfield chemicals.\" Among these, cashew nut shell liquid (CNSL), a key plant-derived material and low-cost byproduct of the cashew industry, has emerged as a promising and economically viable alternative to conventional feedstocks. So far, numerous chemicals and value-added products have been generated from CNSL, establishing its applications across various industries. This review provides a comprehensive overview of recent advancements in CNSL-based oilfield applications, including fuel, crude oil-water emulsions, emulsifiers and demulsifiers, flow improvers for waxy crude oil, corrosion inhibitors, lubricants, enhanced oil recovery (EOR), surfactants and foaming agents, with an emphasis on chemical structure–function relationships. We further present a comparative life-cycle assessment (LCA) of CNSL-based versus conventional oilfield chemicals, highlighting their potential environmental and sustainability benefits. Finally, we discuss market trends in green energy, technological opportunities, challenges, and future research directions aimed at improving reproducibility, scalability, and industrial adoption of CNSL-based additives.

Recent progress has extended AM from simple polymer sensors to ceramic, polymer, and ceramic–polymer composite systems based on jetting, liquid resin–based printing (SLA, DLP, CLIP), extrusion or direct ink writing (DIW), powder-based processes, and emerging multi-material platforms. A central viewpoint of this review is that the electromechanical performance of 3D printed piezoelectrics depends on both the intrinsic material system (such as PZT, BTO, KNN, PVDF and PVDF-TrFE) and the way AM process parameters shape the microstructure through ink or feedstock formulation, printable feature size, curing or sintering depth, layer adhesion, and poling conditions. By organising the literature along this process–structure–property chain, different AM process can be compared on the same basis. Liquid resin–based and DIW methods at present provide the most practical balance between tens-of-micrometres resolution, shape fidelity, and compatibility with ceramic-filled or PVDF-based inks. Jetting and aerosol-jet printing are well suited to patterned thin active layers but remain highly sensitive to ink formulation. Powder-based processes still need better densification control to reach high d₃₃ lead-free ceramics. AM-oriented structural designs, including multilayer stacks, porosity-graded or multiphase lattices, and compliant substrates, can improve sensitivity, durability, and energy harvesting efficiency by matching mechanical impedance and promoting dipole alignment. Remaining challenges include printable high solid loading lead-free systems, stable dispersion and interfacial adhesion at low temperatures, predictive models that link print paths to poling response, and the absence of standardized benchmarking across AM platforms. The integration of data-driven optimization and in situ monitoring with this AM process is identified as an effective way to shorten the ink-to-device iteration cycle and to deliver reproducible, application-specific 3D printed piezoelectric devices.</div></div>","PeriodicalId":18322,"journal":{"name":"Materials Today Sustainability","volume":"32 ","pages":"Article 101257"},"PeriodicalIF":7.9,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145620079","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study investigates the feasibility of using two-part geopolymer stabilized recycled concrete aggregate (RCA) and recycled glass (RG) mixtures in sustainable pavement construction. In this regard, RCA and RG were blended in different proportions and stabilized with alkali-activated fly ash (FA), slag (S), and a binary precursor of (FA+S) at a fixed 50:50 ratio for pavements. The effects of RCA/RG proportion, precursor type and dosage, and curing regime on geopolymer stabilized RCA/RG mixtures were investigated by performing unconfined compressive strength (UCS). The optimum geopolymer stabilized RCA/RG mixtures were further characterized for their resilient modulus and flexural performance through conducting repeated loaded triaxial (RLT) and four-point bending tests. The microstructure of geopolymer stabilized RCA/RG samples were studied scanning electron microscopy (SEM) to understand the reinforcing mechanisms for strength gain. The test results suggested that increasing the RG content led to a decrease in the strength of the geopolymer stabilized RCA/RG mixtures. In contrast, increasing the precursor dosages generally resulted higher UCS values of the stabilized RCA/RG mixtures. Overall, FA geopolymer stabilized RCA/RG mixtures had lower UCS compared to S and (FA+S) geopolymer stabilized RCA/RG mixtures. Most of S and (FA+S) geopolymer stabilized RCA/RG mixtures complied the minimum UCS requirement of 3 MPa stipulated by the local road authority, expect for few stabilized RCA/RG mixtures with addition of 5% precursor dosage.
