Among these, algae-based biodiesel, a third-generation biofuel, has emerged as a promising candidate due to its high productivity, non-competition with food resources, and carbon sequestration potential. This review aims to address a gap in the existing literature by comprehensively analysing algae biodiesel production, including cultivation methods, extraction techniques, and strategies to enhance fuel properties. Furthermore, it offers a novel synthesis of the impact of algae biodiesel on compression ignition engines, focusing on combustion characteristics, engine performance, and exhaust emissions. Key findings indicate that algae biodiesel exhibits shorter ignition delays, gradual heat release rates, and longer combustion durations than conventional diesel. While engine performance remains comparable, algae biodiesel results in slightly lower brake thermal efficiency and higher specific fuel consumption. In terms of emissions, it significantly reduces CO, HC, and PM emissions but leads to marginally higher NOx emissions. The advantages of algae biodiesel, including its renewability, adaptability through species selection or genetic modification, and environmental benefits, underscore its potential as a viable alternative fuel. This review highlights the feasibility of algae biodiesel as a sustainable energy solution, contributing to the transition toward cleaner and more efficient fuel sources.</div></div>","PeriodicalId":100251,"journal":{"name":"Cleaner Chemical Engineering","volume":"11 ","pages":"Article 100178"},"PeriodicalIF":0.0,"publicationDate":"2025-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143942469","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The anatomy laboratory wastewater with high formaldehyde concentration (ALW-CFA) presents potential toxic effects to humans and the ecosystem in general, for this reason, proper treatment is demanded before its discharge. In the present work, the degradation of CH₂O and reduction of toxicity levels of ALW-CFA samples were studied through the application of the process photo-electro-Fered-Fenton process (PEF-Fered). The suitable operational conditions of the process PEF-Fered such as initial solution pH, current intensity, and H₂O₂ initial concentration, were studied by the application of an RSM evaluating the reduction of concentrations of CH₂O and TOC. Then, the increment of O₃ to the PEF-Fered process was performed (PEF-Fered-O₃), aiming to increase the oxidative potential of the system. However, it was observed that the use of many oxidative inputs at the same time (hybrid process) was not interesting for the ALW-CFA degradation, thus, the best treatment strategy which provided a lower toxicity level (LC_{50 %}= 56.94) was the AO followed by H₂O₂ and O₃, with a removal of 90 % of CH₂O and 85 % of TOC, under the following operational conditions, solution pH 4.5; the current intensity of 2.4 and H₂O₂ concentration of 24,000 mg <span>l</span>^-1.

As civilization progresses, the level of environmental pollution with toxic metals has also intensified. The ability to quickly detect heavy metal pollution in wastewater and find its source is critical for environmental monitoring and protection. In the search for cheaper and more economical materials to be used as precipitants, civil construction waste has been used for this application. In this context, the present study aimed to evaluate the utilization of construction and demolition waste (gypsum and cementitious mortar) in the retention of Copper, Lead, and Nickel metal ions. The assessment of the removal capacity of these metal ions using gypsum powder and cementitious mortar was conducted through chemical precipitation using batch experiments. The results obtained for Pb²⁺ ions showed that increasing the mass of gypsum from 10 to 100 g resulted in precipitation rates ranging from 97.29 to 98.31 %. Gypsum also proved to be a viable alternative for Cu²⁺ precipitation with rates of 92.99 to 96.65 %, while the most significant retention rate for Ni²⁺ was observed for the mass of 100 g, reaching 94.63 %. In experiments using different types of cementitious mortar (ACI, ACII, ACIII, and common) as precipitants in a solution contaminated with copper at a constant concentration of 600 mg/L, it was found that the precipitation rates were practically the same, with ACIII mortar showing the highest percentage of precipitation. Therefore, the results obtained demonstrated that construction and demolition waste by-products rich in gypsum and cementitious mortar are efficient in removing toxic metals, representing promising alternatives for wastewater decontamination.</div></div>","PeriodicalId":100251,"journal":{"name":"Cleaner Chemical Engineering","volume":"11 ","pages":"Article 100174"},"PeriodicalIF":0.0,"publicationDate":"2025-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143917282","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results showed that an increase in temperature and pressure improved the fixed carbon content of the blend almost threefold from 19.87 % to 66.93 % and the higher heating value (HHV) to 27.32MJ/kg from 13.90MJ/kg at mild torrefaction temperature of 280°C and gas pressure of 4MPa compared to atmospheric pressure conditions and the lowest temperature investigated. The HHV increased primarily due to a release of bound and unbound moisture and volatile matter. Wood chips had an HHV of 27.00MJ/kg at a torrefaction temperature of 280°C due to the decomposition of hemicellulose and cellulose which enhanced the thermal stability, fixed carbon content and calorific value. However, animal waste had the least incremental increase in HHV (16.45MJ/kg) due to a high initial content of volatile matter and moisture. The improved properties of the blend of materials indicated that pressurized torrefaction was effective in increasing fixed carbon content through secondary polymerization reactions. Moreover, it facilitated the decomposition of cellulose at a lower temperature than the typical range of 315-400°C if conducted at atmospheric pressure.
