Plastic waste and recycling : environmental impact, societal issues, prevention, and solutions
Plastic Waste and Recycling: Environmental Impact, Societal Issues, Prevention, and Solutions begins with an introduction to the different types of plastic materials, their uses, and the concepts of reduce, reuse and recycle before examining plastic types, chemistry and degradation patterns that are organized by non-degradable plastic, degradable and biodegradable plastics, biopolymers and bioplastics. Other sections cover current challenges relating to plastic waste, explain the sources of waste and their routes into the environment, and provide systematic coverage of plastic waste treatment methods, including mechanical processing, monomerization, blast furnace feedstocks, gasification, thermal recycling, and conversion to fuel. This is an essential guide for anyone involved in plastic waste or recycling, including researchers and advanced students across plastics engineering, polymer science, polymer chemistry, environmental science, and sustainable materials.

Transboundary Trade in Plastic Waste and Environmental Concerns: A Case Study from Thailand
Thailand has ratified the Basel Convention and is adhering to its restrictions on the importation of plastic scrap. The Thai government has enforced limitations to decrease the influx of plastic scrap imports, thereby protecting the ecosystem. However, Thailand has emerged as a prominent global hub for the export of plastic waste due to its tax-free zone plastic recycling programs and China’s ban on such imports in 2018. Thailand’s importation of plastic waste for recycling has caused worries due to the accumulation of plastic garbage in the environment. Plastic can be found in seafood, drinking water, rivers, sediments, and wastewater treatment facilities. Thailand is becoming more cautious about importing plastic scraps for recycling due to concerns over the health hazards associated with contaminated plastic. The importation of plastic can significantly impact those engaged in the collection and trade of plastic scrap. Consequently, there are discrepancies in both company operations and plastic management. The ban on plastic scrap imports in Thailand set for 2025 is expected to reduce environmental and human health issues; however, it may also impact the plastic recycling industries and economies both regionally and globally. To address the issue of plastic waste infiltrating the global environment, all nations need to work together at both the regional and global levels to establish effective plastic waste management practices, avoiding the practice of transferring plastic waste to other countries.

Thicker than water : the quest for solutions to the plastic crisis
\"Much of what you've heard about plastic pollution may be wrong. Instead of a great island of trash, the infamous Great Pacific Garbage Patch is made up of manmade debris spread over hundreds of miles of sea--more like a soup than a floating garbage dump. Recycling is more complicated than we were taught: less than nine percent of the plastic we create is reused, and the majority ends up in the ocean. And plastic pollution isn't confined to the open ocean: it's in much of the air we breathe and the food we eat. In Thicker Than Water: The Quest for Solutions to the Plastic Crisis, journalist Erica Cirino brings readers on a globe-hopping journey to meet the scientists and activists telling the real story of the plastic crisis. From the deck of a plastic-hunting sailboat with a disabled engine, to the labs doing cutting-edge research on microplastics and the chemicals we ingest, Cirino paints a full picture of how plastic pollution is threatening wildlife and human health. Thicker Than Water reveals that the plastic crisis is also a tale of environmental injustice, as poorer nations take in a larger share of the world's trash, and manufacturing chemicals threaten predominantly Black and low-income communities. There is some hope on the horizon, with new laws banning single-use items and technological innovations to replace plastic in our lives. But Cirino shows that we can only fix the problem if we face its full scope and begin to repair our throwaway culture. Thicker Than Water is an eloquent call to reexamine the systems churning out waves of plastic waste.\"--Page 2 of cover.

Plastics Waste Management - Processing and Disposal (2nd Edition)
It is seldom that a day goes by without another story or photo regarding the problem of plastics waste in the oceans or landfills. While important efforts are being made to clear up the waste, this book looks at the underlying causes and focuses on plastics waste management. Plastics manufacturers have been slow to recognize their environmental impact compared with more directly polluting industries. However, the environmental pressures concerning plastics have forced the industry to examine their own recycling operations and implement plastics waste management. This book realizes two ideals: That all plastics should be able to persist for as long as plastics are required, and that all plastics are recycled in a uniform manner regardless of the length of time for which it persists. The book examines plastics waste management and systems for the environment, as well the management approaches and techniques which are appropriate for managing the environment. It serves as an excellent and thoughtful plastics waste management handbook.

Plastics waste management
\"Within a specifc ecological-economic system, each material is generally connected to and also dependent on others. Moreover, plastics contribute to the overall integrity of this life system. However, since all plastics contribute to the functional scheme of things in waste generation, it is undoubtedly a very important issue. In particular, plastics provide key applications that are also unique; without plastics, the underlying ecological-economic system would be very different\"-- Provided by publisher.

Toxicity Effects of Polystyrene Nanoplastics with Different Sizes on Freshwater Microalgae IChlorella vulgaris/I
The ubiquitous nature of plastics, particularly nanoplastics, raises concern about their potential effects on primary producer microalgae. Currently, the impacts and potential mechanisms of nanoplastics on microalgae are not fully understood. In this study, the effects of two plain commercial polystyrene nanoplastics (PS-NPs) with different sizes (50 nm and 70 nm) on C. vulgaris were assessed in a concentration range of 0-50 mg/L during 72 h exposure periods. Results revealed that both PS-NPs have dose-dependent toxicity effects on C. vulgaris, as confirmed by the decrease of growth rates, chlorophyll a and esterase activities, and the increase of ROS, MDA, and membrane damage. The membrane damage was caused by the agglomeration of PS-NPs on microalgae and may be the key reason for the toxicity. Compared with 70 nm PS-NPs (72 h EC[sub.50] >50 mg/L), 50 nm PS-NPs posed greater adverse effects on algae, with an EC[sub.50-72h] of 19.89 mg/L. FTIR results also proved the stronger variation of macromolecules in the 50 nm PS-NPs treatment group. This phenomenon might be related to the properties of PS-NPs in exposure medium. The lower absolute zeta potential value of 50 nm PS-NPs induced the stronger interaction between PS-NPs and algae as compared to 70 nm PS-NPs, leading to severe membrane damage and the loss of esterase activity as well as settlement. These findings emphasized the importance of considering the impacts of commercial PS-NPs properties in toxicity evaluation.

A poison like no other : how microplastics corrupted our planet and our bodies
It's falling from the sky and is in the air we breathe. It's in our food, our clothes, and our homes. It's microplastic and it's everywhere--including our own bodies. Scientists are just beginning to discover how these tiny particles threaten health, but the studies are alarming. A Poison Like No Other is the first book to fully explore this new dimension of the plastic crisis. Matt Simon follows the intrepid scientists who travel to the ends of the earth and the bottom of the ocean to understand the consequences of our dependence on plastic. Unlike other pollutants that are single elements or simple chemical compounds, microplastics represent a cocktail of toxicity linked to diseases ranging from diabetes to cancer. There is no easy fix, Simon warns. But we will never curb our plastic addiction until we begin to recognize the invisible particles all around us.

Polymer 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 this book. 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.
