A circular economy for plastics reduces plastic pollution and climate effects and provides social and economic benefits. This article reviews the patent landscape and identifies disruptive technologies that contribute to a circular economy for plastics. Using a collaboration between subject matter experts and ChatGPT, we identified five distinct disruptive technology categories and associated keywords that support a circular economy: bioplastics, chemical recycling, synthetic biology, traceable plastics and waste separation. Using the associated keywords, we categorised patents from 2018 to 2022 into these disruptive technologies to assess current trends. The patent landscape was challenging to navigate due to the deliberately broad language used to construct patents, leading to many irrelevant patents being categorised. Low technology readiness levels of some patents examined also limits the current disruptiveness of these technologies. Adequate financial funding and economic incentives were the most evident barriers to disruptive technology maturity and uptake.</div></div>","PeriodicalId":100960,"journal":{"name":"Next Sustainability","volume":"6 ","pages":"Article 100098"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143163061","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Bio-derived fuels have been blended with conventional fuels to address the depletion of fossil fuels and their associated greenhouse effect. The researchers focus on finding new technology that leads to carbon-free mobility. Renewable energy sources such as ammonia, hydrogen, and CNG are becoming increasingly popular as efficient substitutes for traditional fuels. Due to the concern about the production and storage of hydrogen, ammonia is gaining momentum due to its better hydrogen-storing capacity. This review paper aims to discuss the various ammonia production processes, the possibilities of ammonia as fuel in conventional CI engines, and the use of ammonia in internal combustion engines. Research has shown that the addition of ammonia to CI enhances its performance, and the use of dual fuel can boost the output's economic efficiency. However, it is important to note that this approach may also lead to increased NOₓ emissions. Some of the most important things that the review showed were that ammonia works well in dual fuel mode, 40–60 % diesel fuel energy is needed for maximum fuel efficiency, and NO emissions go down if ammonia replaces less than 40 % of the energy. For this reason, ammonia could potentially serve as a fuel for CI engines, leading to improved performance and a reduction in NOₓ emissions.</div></div>","PeriodicalId":100960,"journal":{"name":"Next Sustainability","volume":"5 ","pages":"Article 100116"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143455050","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Dyes in wastewater have an adverse influence on the aquatic ecosystem. This research concerns the suitability of fish biowaste adsorbent for dye removal from tannery wastewater. The obtained biosorbent was analyzed through Fourier Transform Infrared (FTIR) Spectroscopy, pH point of zero charge (pHpzc), Energy Dispersive Spectroscopy (EDS), and Scanning Electron Microscope (SEM). The dye removal efficiency was evaluated by monitoring the biosorbent dose, settling time, stirring time, and temperature effect. The dye adsorption mechanism was characterized using Freundlich and Langmuir’s regression models. The maximum dye removal efficiency (81.8 %) was achieved with a 2 g biosorbent dose per 50 mL of wastewater, 25 min stirring time, 30°C temperature, and 20 h settling time at pH 4.8. The adsorption kinetics demonstrated that the pseudo-second-order reaction (PSO) model shows a good regression coefficient (<em>R</em>^<em>2</em>=0.94). The removal of Total Dissolved Solids (TDS), Biochemical Oxygen Demand (BOD), turbidity, and Chemical Oxygen Demand (COD) were 39.8 %, 69.7 %, 48.1 %, and 90.1 %, respectively.

Therefore, there is always a demand for efficient disposal and recycling methods. This study provides an overview of the use of biowaste-derived 3D printing feedstocks for bone tissue engineering applications.

The incorporation of zeolite and amine-zeolite ZSM-22 in the selective PA layer resulted in distinct ridge-like and valley-like surface morphologies, contributing to improved hydrophilicity and fouling resistance. Comprehensive characterisation using X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), and water contact angle (WCA) analysis confirmed the successful incorporation and uniform dispersion of zeolite and amine-zeolites fillers within the PA layer. The functionalised PA layers demonstrated superior hydrophilicity, resulting in significant improvements in water flux, high anti-fouling ratios and salt rejection compared to the zeolite PA-TFC membranes. The obtained PA-TFC membrane structural design, supported on ZSM-22/polyethersulfone ultrafiltration (ZSM-22/PES UF) substrate, played a crucial role in ensuring mechanical stability and promoting interfacial bonding. The amine-zeolites PA-TFC membranes achieved exceptional water fluxes, reaching up to 48.92 L·m⁻²·h⁻¹ ·bar⁻¹ , and exhibited fouling ratios ranging from 65.78 % to 73.68 % as well as salt rejection to about 77 %.

Despite minimal performance variations among the different membrane configurations, consistent and robust antifouling behavior was observed across all samples. These findings underscore the promise of amine-zeolite ZSM-22 PA-TFC membranes as high-performance candidates for achieving enhanced flux, fouling resistance, and selective separation, contributing valuable insights for the advancement of membrane technology in water treatment applications.</div></div>","PeriodicalId":100960,"journal":{"name":"Next Sustainability","volume":"6 ","pages":"Article 100097"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143163057","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
