Three families of zeolites were synthesized hydrothermally: a reference zeolite without biomass, one with lignin, and another combining lignin and sugarcane bagasse. Biomass has been shown to modify the zeolite structure by reducing the crystal size, favouring aluminium incorporation within the framework and reducing the number of defects as internal silanols. These modifications are attributed to the chemical interactions between biomass and inorganic precursors present in solution. The catalytic performance of these zeolites was analysed in <em>n</em>-hexane cracking and in the methanol to olefin (MTO) reactions. Zeolites synthesized with biomass demonstrated improved catalytic stability and selectivity towards light olefins, thanks to an enhanced diffusion path. Lignin, in particular, helped minimize structural defects, thus improving the catalyst lifetime. The addition of biomass offers significant advantages for tailoring zeolite properties while using renewable and abundant resources. This innovative approach opens up interesting prospects for the sustainable design of catalytic materials. It also enables agricultural and industrial wastes to be recycled into high value-added applications, strengthening the links between green chemistry and industrial performance.</p>","PeriodicalId":74745,"journal":{"name":"RSC sustainability","volume":" 5","pages":" 2221-2234"},"PeriodicalIF":0.0,"publicationDate":"2025-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.rsc.org/en/content/articlepdf/2025/su/d5su00072f?page=search","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143918904","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}

Circular cellulose resources might be agricultural wastes. Here we evaluated oat husks, wheat straw, potato pulp and pressed sugar beet pulp which are available in sufficient amounts in Sweden to produce dissolving pulp using the soda pulping process. Initial pulps from oat and wheat were further refined to achieve the purity of the dissolving pulp while potato and sugar beets were discarded due to processing difficulties. High purity dissolving pulps were obtained including both acid prehydrolysis pretreatment, soda cooking and a bleaching sequence. To evaluate the environmental impact of the production of dissolving pulp from oat husks and wheat straw, the process was scaled-up from lab scale to industrial scale and simulated, using Aspen PLUS. The results of the process simulations were evaluated through life-cycle assessment. Processing wheat straw required a higher chemical and energy demand compared to oat, but wheat pulp had a lower environmental impact. Both wheat and oat pulp had a higher impact than wood due to differences in cultivation.

In addition to reducing global carbon emissions, the provision of clean “green” energy, reduction of water pollution and production of high value chemicals in a sustainable manner are clear priorities for sustainable economic growth. The photocatalytic valorisation of real-world substrates (waste biomass, plastic pollution and wastewater) is an opportunity to contribute significantly towards tackling water pollution, cutting CO<small><sub>2</sub></small> emissions and contributing to sustainably producing value added chemicals and hydrogen from waste materials and water contaminants/pollutants. To date, however, research is critically lagging in terms of the utilization of actual real-world substrates and instead concentrates on much simpler model compounds such as sugars, monomers, dyes and individual pollutants. Lack of progress in this field is further exacerbated by the general lack of scaling up of photocatalytic technology. Nevertheless, there are some pioneers who have explored the photocatalytic valorization of real-world waste materials which have been highlighted in this review. This review considers the application of semiconductor photocatalysis for such applications with a particular focus on valorisation of waste biomass (<em>e.g.</em> cardboard, grass, wood), plastic pollution (<em>e.g.</em> plastic bottles) and wastewater effluents (<em>e.g.</em> from juice processing factories) to produce hydrogen and value-added chemicals.

This study conducts a comprehensive life cycle analysis of various PV technologies using primary data within a unified framework and explores different scenarios to assess the impact of technology and management on greenhouse gas (GHG) emissions and energy payback. The results indicate that transitioning from multi-crystalline to monocrystalline silicon reduces PV-related GHG emissions by 7.9–40.5% and improves energy payback by 1.5–52.5%. Additionally, effective management and technological advancements decrease GHG emissions by 29.6–34.3% compared to the current scenario. Integrating these factors into grid decarbonization efforts would reduce emissions to less than 7.2 gCO<small><sub>2</sub></small>-eq per kW per h, shorten the energy payback time to less than 2.0 years, and boost energy returns by more than 18.4 times.

Current methods for solder removal are inefficient, produce harmful gases and by-products. This work aims to use catalytic etchants in concentrated ionic media, to improve the sustainability of recycling techniques. The viscosity of these solutions is often perceived as a limiting factor for ion mobility, so ultrasonic agitation has been used to improve mass transport. Cyclic voltammetry and linear sweep voltammetry have been used to investigate the redox behaviour of tin and lead in solder, and how ultrasound can overcome passivation and improve the dissolution of these metals. Ultrasound results in a linear response between the slope of the LSV and solution conductivity for tin, suggesting a migration-controlled mechanism, however passivation still occurred with lead, showing that there is still some diffusion control.
