“…The disposal of the dewatered sludge was the main cost factor, representing 57 and 64% of the overall costs for BMP and full-scale data, respectively. Similar observations were made by Vinardell et al (2021) who conducted a techno-economic evaluation of the co-digestion of FW and SS after implementing an anaerobic membrane bioreactor in the mainstream of a WWTP. The co-digestion of BW and GTS generated a surplus of thermal energy which could be further utilized to dry the dewatered sludge.…”

“…LCA studies that assessed the environmental impacts of pyrolysis ,− and gasification − of solid digestate from municipal sewage sludge were investigated in China, Italy, and Morocco that applied CML, ReCiPe, and IPCC. These methods were used to assess the environmental impacts of recovering nutrients from solid digestates of wet feedstocks through composting − and from their liquid digestates via struvite precipitation , and sequencing batch reactors , in USA, Germany, Italy, Spain, and Iran. Studies in Germany and China compared the environmental impacts between composting, − hydrothermal carbonization, , and gasification of organic municipal solid waste and its solid digestate using different LCA methods.…”

Municipal and agricultural organic waste can be treated to recover energy, nutrients, and carbon through resource recovery and carbon capture (RRCC) technologies such as anaerobic digestion, struvite precipitation, and pyrolysis. Data science could benefit such technologies by improving their efficiency through data-driven process modeling along with reducing environmental and economic burdens via life cycle assessment (LCA) and techno-economic analysis (TEA), respectively. We critically reviewed 616 peer-reviewed articles on the use of data science in RRCC published during 2002−2022. Although applications of machine learning (ML) methods have drastically increased over time for modeling RRCC technologies, the reviewed studies exhibited significant knowledge gaps at various model development stages. In terms of sustainability, an increasing number of studies included LCA with TEA to quantify both environmental and economic impacts of RRCC. Integration of ML methods with LCA and TEA has the potential to costeffectively investigate the trade-off between efficiency and sustainability of RRCC, although the literature lacked such integration of techniques. Therefore, we propose an integrated data science framework to inform efficient and sustainable RRCC from organic waste based on the review. Overall, the findings from this review can inform practitioners about the effective utilization of various data science methods for real-world implementation of RRCC technologies.

“…Second, microalgae-based wastewater remediation is a process of fixing carbon dioxide (CO 2 ) and releasing oxygen (O 2 ), while traditional wastewater treatment technologies, including aerobic digestion and anaerobic fermentation, produce a large amount of greenhouse gases (CO 2 and CH 4 ). 5,6 Owing to the aforementioned advantages, in recent years microalgaebased wastewater remediation has emerged into the limelight. 7 Traditional methods of harvesting microalgae mainly include centrifugation, filtration, gravity-driven sedimentation and flocculation.…”

The high cost of biomass harvesting by centrifugation and high safety risks of collected algal biomass by chemical flocculation are serious problems jeopardizing the industrial implementation of microalgae bio-products. Recently, microalgae immobilization is regarded as a promising technology with the potential of lowering biomass production cost and ensuring biomass safety in the industry. Therefore, microalgal biofilms, an effective and affordable way to immobilize algal cells, are emerging into the limelight. This paper summarizes the progress achieved in biofilm system design and biofilm formation mechanisms. Newly designed algal biofilm systems are compared to demonstrate their advantages and weaknesses. Besides, mechanisms associated with the two steps -initial attachment of microalgae and biofilm thickeningof biofilm formation are discussed in this paper. Factors such as substratum material, algal strain and operational parameters, which could impact the formation and operation of algal biofilm, are demonstrated. Efforts devoted to the industrial application of algal biofilm to treat wastewater are discussed. The biotechnology of microalgal biofilm is currently at the critical stage of developing from fundamental research to industrial implementation. Undeniably, there are still many problems that limit the wide use of algal biofilm for biomass production and wastewater treatment. In this paper, we present some potential solutions to current problems and discuss the development trends of algal biofilm in the foreseeable future. It is expected that by addressing current problems microalgal biofilm will be widely used at the industrial scale.
