Petroleum refinery oily sludge (PROS) is a major by-product of the processes and a major contributor to pollution in the oil and gas industry. In this study, Response Surface Methodology (RSM) was used for optimising and modelling experimental work. Thermally treated PROS replaced fly ash (FA) at 5–20 % in geopolymer mortar mixes at a fixed combination of sodium silicate (Na₂SiO₃) and sodium hydroxide (NaOH). The visual observations and effects of PROS on the density and compressive strength of PROS geopolymer mortar (PGM) were studied. PGM with 10 % replacement of PROS had the maximum compressive strength of 38.17 MPa after 28 days. P-values obtained from the quadratic models developed for the synergistic effect of FA-PROS on density and compressive strength were less than 0.005. Optimisation of the synergistic effect of FA-PROS binder produced an optimal combination of both materials for maximum compressive strength and density of 2200 kg/m³ with desirability factor of 0.981. This investigation shows that replacing PROS with FA in geopolymer mortar can result in a new supply chain for greener binder materials in geopolymer mortar.</p></div>","PeriodicalId":93463,"journal":{"name":"Journal of hazardous materials letters","volume":"4 ","pages":"Article 100076"},"PeriodicalIF":0.0,"publicationDate":"2023-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49858971","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 present review showed the different metabolic ways of microbes with the emphasis on the anaerobic microbial dechlorination (including chemical, biological and nanotechnology-based strategies), that have been employed to mitigate the chlorinated pollutants. Chemical and nanomaterial science has made substantial advancement in several aspects of dechlorination over the past two decades, providing information about the process and the outcome of the reaction. However, these chemical processes are expensive to start with and pose ecological hazards. So, extensive research has been done to come up with eco-friendly biological alternatives). Under anaerobic conditions, dehalorespiring bacteria are capable of dechlorinating chloroethenes by mediating a stepwise replacement of chlorine with hydrogen resulting in the sequential conversion of perchloroethylene (PCE) to trichloroethylene (TCE), dichloroethylene (DCE) isomers, vinyl chloride (VC), and finally, ethane. Among many dehalorespiring bacterial isolates, only a few strains of the genus <em>Dehalococcoides</em> completely converted the chloroethenes to nontoxic ethane. In the paper we will, therefore, focus on this <em>Dehalococcoides spp.</em> Several factors influence the dechlorination activity between different dehalogenating bacteria. The vcrA and bvcA genes dechlorinate VC into ethene, which are essential for complete dechlorination. These pathways offer understanding of potential bioremediation of chlorinated aliphatic or aromatic compounds by <em>Dehalococcoides</em> with the likelihood of highly effective bioremediation.</p></div>","PeriodicalId":93463,"journal":{"name":"Journal of hazardous materials letters","volume":"3 ","pages":"Article 100065"},"PeriodicalIF":0.0,"publicationDate":"2022-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2666911022000181/pdfft?md5=56635a9ccc761f79d51985923ddd0596&pid=1-s2.0-S2666911022000181-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42478453","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}
