Bryant Brenda, Hall Betty. Municipal and Industrial Waste: Sources, Management Practices and Future Challenges

Nova Science Pub Inc, 2018. — 311 p. — (Waste and Waste Management). — ISBN10: 1536134414, 13 978-1536134414.In this collection, the authors open with a review of current state of the art methods for the recovery and reuse of selected monomers and biomacromolecules (such as proteins and nucleic acids) from municipal solid waste. They discuss the most relevant recoverable chemical building blocks and biomacromolecules, as well as their potential applications. Following this, polyethylene terephthalate is analyzed as one of the major post-consumer plastics in solid waste streams because of the ongoing expansion of the PET bottle market. A study is conducted wherein co-pyrolysis is proposed for co-processing PET wastes with woody biomass in order to improve the quality and yield of liquid products for their use as fuels. A subsequent study proposes a recycling process for the recovery of zinc and manganese from Zn-Mn batteries, the goal of which is to determine the optimal conditions of manganese and zinc extraction from black mass of spent zinc-manganese batteries. The ability to obtain final products such as manganese oxide(IV) from recycling material makes it possible to use them in new batteries. Also in this collection, the authors synthesize wood ash based geopolymer to determine its optimal conditions. Another study details the aspects of waste generation sources and management practices such as collection, storage, transportation and disposal in an environmental and economic manner, along with upcoming challenges. A review of sludge pretreatment and extracellular polymeric substance extraction enhancing the sludge management process is presented. The closing paper describes the equilibrium and kinetic studies which contributed to our understanding of the properties of the new sorbent such as chemically modified coal fly ash. Based on the sorption capacity obtained, modified coal fly ash is proposed for the treatment of wastewaters containing heavy metal and dye.
