Non-conventional green extraction techniques are gaining momentum due to their higher extraction yields, low environmental impact, and better protection of pigments against degradation compared to conventional extraction methods.

Thus, to push the chemical industry further toward renewability, the production of bio-based aromatics is an essential step to take. The implementation of bio-based aromatics to replace petrochemical aromatics can proceed in two main ways: as direct replacement <em>via</em> renewable drop-in or as replacement by renewable functional alternatives. However, the implementation of both pathways still requires significant process optimization toward large-scale application in industrial processes. In this work, renewable drop-in is mainly discussed in the context of pyrolysis and Diels–Alder reactions.

The safe and sustainable disposal of electronic waste (e-waste) is challenging because it is composed of both hazardous and non-hazardous substances. Concurrently, geopolymers offer multifaceted benefits and have potential applications, particularly in the realm of building materials. Drawing inspiration from these circumstances, this article delves into the possibility of using non-metallic fractions of e-waste—such as plastic (e-plastic) and glass (e-glass)—as aggregates or/and precursors in geopolymer production. The characteristics of these e-waste components, their suitability for incorporation, and the rationale behind their selection form a focal point of this article. The literature suggests that incorporating less than 50% of e-waste fractions to produce geopolymers exhibits adequate compressive strength to fabricate at least medium-grade construction materials. However, more experimental investigations are required in this domain to explore and optimize the utilization of such composites in various applications in the construction industry.</p></div>","PeriodicalId":54228,"journal":{"name":"Current Opinion in Green and Sustainable Chemistry","volume":"48 ","pages":"Article 100930"},"PeriodicalIF":9.3,"publicationDate":"2024-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141061140","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This review delves into the transformative role played by nanomaterials, specifically graphene-based catalysts, metal–organic frameworks, biomass waste materials, and carbon nanotubes, in augmenting various facets of biofuel production. Noteworthy examples include the application of metal-modified graphene oxide composite catalysts, incorporating aluminium and ferric, revealing a significant 25% reduction in free fatty acid content and a remarkable 15% increase in methyl hexadecanoic yield. Furthermore, the eco-friendly synthesis of TiO<sub>2</sub> nanoparticles showcased consistently high biodiesel yields, reaching 95% over 10 cycles, underscoring its economic advantages and stability. However, it is essential to acknowledge the potential drawbacks associated with nanomaterial utilization in biofuel production. Environmental concerns, such as nanoparticle release during production processes and their impact on ecosystems as well as safety issues related to exposure to nanoparticles, require careful consideration. This comprehensive overview encompasses recent studies on green synthesis, hydrothermal-assisted carbonization, gold nanoparticles in biomass hydrolysis, and the impact of nano-fuel technology on engine characteristics. Innovations in catalysts and processes, such as sulfonic acid functionalized metal–organic frameworks and magnetic MOF-derived materials, are scrutinized for their sustainability. The review culminates with a thorough analysis of the environmental and economic impacts, accentuating both the potential benefits and challenges entailed in the seamless integration of nanotechnology into biofuel production.</p></div>","PeriodicalId":54228,"journal":{"name":"Current Opinion in Green and Sustainable Chemistry","volume":"47 ","pages":"Article 100925"},"PeriodicalIF":9.3,"publicationDate":"2024-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140787993","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
