TL;DR: Though the effluent of two concentrated leachates did not meet the maximum allowable criterion for leachate direct or indirect discharge standard in China, the composition and properties of organic matters in concentratedLeachate were changed significantly after entire ozonation reaction, which would be conducive to the further biological treatment or other advanced treatment.

TL;DR: Analysis of key enzyme activities indicated that the presence of DCF reduced the activities of exopolyphosphatase and polyphosphate kinase, which revealed that DCF promoted the ratio of protein to polysaccharide in activated sludge extracellular polymers and inhibited anaerobic phosphorus release and oxic phosphorus uptake.

TL;DR: In this paper, the authors summarize the recent experimental and computational research progress in the modification of MnO2 single species by morphology control, structure construction, facet engineering, and element doping.
Abstract: Manganese dioxide (MnO2 ) is a promising photo-thermo-electric-responsive semiconductor material for environmental applications, owing to its various favorable properties. However, the unsatisfactory environmental purification efficiency of this material has limited its further applications. Fortunately, in the last few years, significant efforts have been undertaken for improving the environmental purification efficiency of this material and understanding its underlying mechanism. Here, the aim is to summarize the recent experimental and computational research progress in the modification of MnO2 single species by morphology control, structure construction, facet engineering, and element doping. Moreover, the design and fabrication of MnO2 -based composites via the construction of homojunctions and MnO2 /semiconductor/conductor binary/ternary heterojunctions is discussed. Their applications in environmental purification systems, either as an adsorbent material for removing heavy metals, dyes, and microwave (MW) pollution, or as a thermal catalyst, photocatalyst, and electrocatalyst for the degradation of pollutants (water and gas, organic and inorganic) are also highlighted. Finally, the research gaps are summarized and a perspective on the challenges and the direction of future research in nanostructured MnO2 -based materials in the field of environmental applications is presented. Therefore, basic guidance for rational design and fabrication of high-efficiency MnO2 -based materials for comprehensive environmental applications is provided.

TL;DR: A review on current US municipal solid waste-to-energy trends highlighted regional contrasts on technology adoption, unique challenges of each technology, commonly used decision support tools, and major operators as mentioned in this paper.
Abstract: This review on current US municipal solid waste-to-energy trends highlighted regional contrasts on technology adoption, unique challenges of each technology, commonly used decision support tools, and major operators. In US only 13% of MSW is used for energy recovery and 53% is landfilled. There are 86 WTE facilities that mostly use Mass-Burn and Refuse-Derived Fuel technologies and are concentrated in densely populated northeast (predominantly in New York) and the State of Florida. For the rest of the country most of the MSW ends up in landfills equipped with gas recovery, which is supplied to homes or used for electricity generation. However, there are many pilot and experimental systems based on advanced gasification and pyrolysis processes, which are viewed as potential technologies to respond to an issue of landfills nearing full capacity in various US states. These systems are viewed as “cleaner” (65% less toxic residue) than established mass burn technologies but not matured to commercialization due technical and cost hurdles. Operation and maintenance costs between $40-$100 per ton of MSW were reported for gasification systems. The heterogeneous nature of MSW, gas cleaning and air pollution controls are the main disadvantages. Key design and decision support tools used by the scientific community and major operators in US include: Techno-economic analysis, Life cycle sustainability assessment, and Reverse logistics modeling. A conclusion drawn from reviewed studies is that adoption of thermal WTE technologies in US could continue to increase, albeit slowly, in coastal and urban areas lacking suitable lands for new landfills.
