This book provides an overview of recycled polyesters, which are an important sustainable raw material in textile production. It discusses the manufacturing methods and the unique properties of recycled polyesters manufactured using the different methods. It also highlights the various test methods and identification mechanisms for recycled polyesters, which are very essential for ensuring the traceability and conformity of usage of recycled polyester in the final product.
This book examines the environmental footprints of recycled polyesters, highlighting the benefits and impact of recycling polyester waste and preparing it to replace virgin polyester in the raw material stage. It also discusses the importance of recycled polyester as a sustainable raw material in textile production.
This book outlines a methodology for producing macro recycled polypropylene (PP) fibres with optimal mechanical properties and illustrates the reinforcing effects of recycled PP fibres in concrete. It describes the great potential of using these fibres in concrete applications such as footpaths and precast elements. Further, it sheds new light on the environmental impacts of using recycled PP fibres, which are evaluated by means of cradle to gate life cycle assessment based on the Australian context. The use of recycled PP fibre not only helps reduce consumption of virgin materials like steel or plastic but also provides an attractive avenue for recycling plastic waste. The book will appeal to engineers, governments, and solid waste planners, and offers a valuable reference for the plastic waste recycling and plastic fibre reinforced concrete industries. /div
The former Blessed Virgin Mary has spent the past two thousand years looking after others, only to find that her story has been lost in a melee of male privilege. Studying at a theological college, she hopes to tell her truth and free herself.
In the 21st century, management of municipal solid waste (MSW) continues to be an important environmental challenge facing the U.S. Climate change is also a serious issue, & the U.S. is embarking on a number of voluntary actions to reduce the emissions of greenhouse gases (GHGs) that can intensify climate change. By presenting material-specific GHG emission factors for various waste management options, this report examines how the two issues -- MSW management & climate change -- are related. The report's findings may be used to support a variety of programs & activities, including voluntary reporting of emission reductions from waste management practices. Charts, tables & graphs.
Use of Recycled Plastics in Eco-efficient Concrete looks at the processing of plastic waste, including techniques for separation, the production of plastic aggregates, the production of concrete with recycled plastic as an aggregate or binder, the fresh properties of concrete with plastic aggregates, the shrinkage of concrete with plastic aggregates, the mechanical properties of concrete with plastic aggregates, toughness of concrete with plastic aggregates, modulus of elasticity of concrete with plastic aggregates, durability of concrete with plastic aggregates, concrete plastic waste powder with enhanced neutron radiation shielding, and more, thus making it a valuable reference for academics and industrial researchers. - Describes the main types of recycled plastics that can be applied in concrete manufacturing - Presents, for the first time, state-of-the art knowledge on the properties of conventional concrete with recycled plastics - Discusses the technological challenges for concrete manufactures for mass production of recycled concrete from plastic waste
This book presents an authoritative account of the potential of recycled polymer blends and composites such as recycled rubber, Polypropylene, Poly(Vinylidene Fluoride) (PVDF), polyhydroxybutyrate-3-valerate (PHBV), Polyethylene, and similar compounds, in polymer recycling industries. It highlights the latest research on fundamentals of recycled polymer blends and composites such as physical, chemical, mechanical and thermal properties and morphological studies. The book also provides a comprehensive state of the art review of recycling of polymer blends and composites for sustainability. Polymeric substances recycled from excess sludge in wastewater treatment plants, reinsertion of Poly(Vinylidene Fluoride) (PVDF), polyolefin and Polypropylene post-Industrial waste by primary recycling, as well as the recent development of biomass and COVID-19 plastic waste derived char filled natural starch biocomposite briquettes are also covered.
