Book Description
Bachelor Thesis from the year 2016 in the subject Chemistry - Materials Chemistry, , course: Chemistry, language: English, abstract: The use of waste plastics in concrete pavement block is a partial solution to the environmental and ecological challenges associated with the use of plastics. The aim of this research is to reduce environmental pollution by using waste PET bottles to produce pavement blocks. In this study, Voltic bottles were first used to replace cement in the production of pavement blocks. The polymeric material was first shredded and melted in an aluminum container at a temperature range of 250 oC - 260 oC and the quarry dust and sand were added in their respective ratios. In another set of studies, the waste Voltic bottles were used as a partial replacement for quarry dust in the manufacturing of pavement blocks. The cleaned waste plastics bottles were first cut into flakes and then incorporated into the concrete mixture. Test conducted involved the effect of sulphuric acid on the weight of pavement, its water absorption and compressive strength. In the first studies, when PET bottles were used to replace cement, the results obtained had the compressive strength almost the same as that of the control sample which contain no plastic. The percentage water absorbed was less and it also had good resistance for acid. In the second studies when PET was used to replace quarry dust partially, the compressive strength was a little bit lower than the control. Its water absorption was less and it also had good resistance to acid. From the above findings, PET pavement blocks have a good strength and can therefore be used for any construction work.

Book Description
The civil engineering sector accounts for a significant percentage of global material and energy consumption and is a major contributor of waste material. The ability to recycle and reuse concrete and demolition waste is critical to reducing environmental impacts in meeting national, regional and global environmental targets. Handbook of recycled concrete and demolition waste summarises key recent research in achieving these goals.Part one considers techniques for managing construction and demolition waste, including waste management plans, ways of estimating levels of waste, the types and optimal location of waste recycling plants and the economics of managing construction and demolition waste. Part two reviews key steps in handling construction and demolition waste. It begins with a comparison between conventional demolition and construction techniques before going on to discuss the preparation, refinement and quality control of concrete aggregates produced from waste. It concludes by assessing the mechanical properties, strength and durability of concrete made using recycled aggregates. Part three includes examples of the use of recycled aggregates in applications such as roads, pavements, high-performance concrete and alkali-activated or geopolymer cements. Finally, the book discusses environmental and safety issues such as the removal of gypsum, asbestos and alkali-silica reaction (ASR) concrete, as well as life-cycle analysis of concrete with recycled aggregates.Handbook of recycled concrete and demolition waste is a standard reference for all those involved in the civil engineering sector, as well as academic researchers in the field. - Summarises key recent research in recycling and reusing concrete and demolition waste to reduce environmental impacts and meet national, regional and global environmental targets - Considers techniques for managing construction and demolition waste, including waste management plans, ways of estimating levels of waste, the types and optimal location of waste recycling plants - Reviews key steps in handling construction and demolition waste

Book Description
The world is literally awash with plastics and this book practically provides a broad overview of plastic recycling procedures and waste management. With the huge amount of plastics floating in the oceans, fish and other sea creatures are directly suffering the consequences. On land, city leaders and planners are banning one-use plastics as well as plastic bags from grocery stores in an effort to stem the use. Many countries have made official announcements and warnings concerning the pollution caused from plastic wastes. These urgent developments have stimulated the author to study the problem and write Polymer Waste Management. Plastic recycling refers to a method that retrieves the original plastic material. However, there are many sophisticated methods available for the treatment and management of waste plastics such as basic primary recycling, where the materials are sorted and collected individually. In chemical recycling, the monomers and related compounds are processed by special chemical treatments. Other methods, such as pyrolysis, can produce fuels from waste plastics. These methods and others are treated comprehensively in the book. This groundbreaking book also discusses: General aspects, such as amount of plastics production, types of waste plastics, analysis procedures for identification of waste plastic types, standards for waste treatment, contaminants in recycled plastics. Environmental aspects, such as pollution in the marine environment and landfills. The advantages of the use of bio-based plastics. Recycling methods for individual plastic types and special catalysts.

Book Description
Thermal Analysis (TA) has become an indispensable family of analytical techniques in the polymer research. The increased importance of these techniques can be seen as the result of three more or less parallel developments:• a tempestuous development of TA measuring techniques in combination with a high degree of automation,• the strongly increased understanding of the underlaying theory and,• the increasing knowledge of the relation between the polymers' chemical structure and their physical properties.These areas are still in their developmental stages, especially the third area. The increasing knowledge of the dependence of physical properties on chemical structure just accentuated more and more the need for accurate thermoanalytical measurements, and this knowledge is very important for the first stages of the development of new polymeric systems. Besides, the contribution of TA remains necessary for the technical and commercial development of such a new polymer system. The use of the various TA techniques in these processes is described in this book in nine chapters, while chapter ten illustrates the information obtained about different polymers during special case studies.This book illustrates in this way, applications of a wide variety of TA techniques whilst it is written from a materials characterisation rather than from a TA point of view with attention being paid to the chemical structure/physical properties correlations.

Book Description
”Reduce, Reuse, Recycle, and Recover“ is the sustainable guideline that has replaced the ”Take, Make, Waste“ attitude of the industrial age. Based on their background at the ETH Zurich and the Future Cities Laboratory in Singapore, the authors provide both a conceptual and practical look into materials and products which use waste as a renewable resource. This book introduces an inventory of current projects and building elements, ranging from marketed products, among them façade panels made of straw and self-healing concrete, to advanced research and development like newspaper, wood or jeans denim used as isolating fibres. Going beyond the mere recycling aspect of reused materials, it looks into innovative concepts of how materials usually regarded as waste can be processed into new construction elements. The products are organized along the manufacturing processes: densified, reconfigured, transformed, designed and cultivated materials. A product directory presents all materials and projects in this book according to their functional uses in construction: load-bearing, self-supporting, insulating, waterproofing and finishing products.
