This collection of articles relates to a research area currently developing in the Humanities, which calls for philosophical and historical approaches to questions of sustainable development and waste management. The title of the issue reflects the central questions raised by all contributors: how are waste and abundance represented, how may we conceptualize these representations, and what ethical problems do they raise? Particular attention is paid to the cultural and moral factors that condition our attitudes to waste and the ways in which literature addresses the problematic relationship that binds production, consumption and waste to social and political systems.

Abundance methods offer an alternative for growing food and other forms of energy with plentiful resources that are cheap and will not run out - primarily solar energy, CO2 and sterilized waste stream nutrients. Abundance allows affordable organic food production in any practically any climate, altitude, latitude or geography. Freedom foods redesign our food supply from the foundation of the food chain with microcrops. Freedom foods free consumers for smart food choices, growers from fossil resource cost and consumption and ecosystems of waste and pollution. Peace microfarms liberate growers from dependence on increasingly expensive cropland, fresh water and other non-renewable resources. Peace microfarms avoid conflicts over diminishing natural resources by growing microcrops using abundance methods. Microcrops include the full spectrum of microorganisms such as algae, yeast, fungi, bacteria, archaea, plankton and many others. Microcrops deliver sustainable advantages over field crops. Peace microfarms produce 20 to 30 times more food per acre every year than modern agriculture. Microfarms scale to any size and may be sited practically anywhere, including cities. Growers recover low cost nutrients from sterilized waste streams and transform them into valuable freedom foods and other products. Growers use abundance methods to assure a sustainable food supply for many generations.

This qualitative study, grounded theory oriented, identifies familial affection and preference for abundance as major drivers of wasted food in lower-middle income American families. These positive intentions provide an improved understanding of household food waste, a problem with high environmental impact and moral implications. Based on empirical data collected from twenty caregivers, via in-depth interviews, observations, and analysis of photos, this study provides fresh insights. One such insight is regarding how stockpiling comfort foods in abundance - a form of both boosting positive self-emotions and showing affection for kids - can promote greater food waste. Other antecedents identified include multiplicity of choices, convenience, procrastination and unplanned routines. In sum, this research identifies a negative outcome of affection and food abundance in the family context, while providing a theoretically relevant general framework. Authors suggest increasing the awareness of nutritional gatekeepers through the alignment of communications and behavioral economics principles.

Waste: A Handbook for Management, Second Edition, provides information on a wide range of hot topics and developing areas, such as hydraulic fracturing, microplastics, waste management in developing countries, and waste-exposure-outcome pathways. Beginning with an overview of the current waste landscape, including green engineering, processing principles and regulations, the book then outlines waste streams and treatment methods for over 25 different types of waste and reviews best practices and management, challenges for developing countries, risk assessment, contaminant pathways and risk tradeoffs. With an overall focus on waste recovery, reuse, prevention and lifecycle analysis, the book draws on the experience of an international team of expert contributors to provide reliable guidance on how best to manage wastes for scientists, managers, engineers and policymakers in both the private and public sectors. - Covers the assessment and treatment of different waste streams in a single book - Provides a hands-on report on each type of waste problem as written by an expert in the field - Highlights new findings and evolving problems in waste management via discussion boxes

The proceedings in this work present 60 papers on mine and mill tailings and mine waste, as well as current and future issues facing the mining and environmental communities. This includes matters dealing with technical capabilities and developments, regulations, and environmental concerns.

Food insecurity can result from various events. While an adequate food supply is necessary, when food is abundant the entitlement to food is limited by endowments, the ability to trade, and potential transfers. This volume considers trends in economic growth, agricultural productivity growth, income and other policies that shape food security.

Plastic Waste Management Comprehensive resource on innovative and breakthrough developments in plastic waste management, covering a wide range of processing techniques and applications Plastic Waste Management offers a complete guide to the best plastic waste management practices through recycling, incineration, landfill, and other processes, discusses applications of plastic waste management including energy generation, biochemical production, construction, and food packaging, covering current challenges relating to plastic waste, explaining the sources of waste and their routes into the environment, and providing systematic coverage of plastic waste treatment methods, including mechanical processing, monomerization, blast furnace feedstock, gasification, and thermal recycling. The book also discusses different biodegradation mechanisms of plastic wastes and ecotoxicity and ecological Implications of marine plastic debris. From a cultural perspective, the book provides information regarding environmental and health implications, societal issues, and current challenges associated with plastic waste management. Written by leading experts in the field and edited by two highly qualified academics, Plastic Waste Management covers specific sample topics such as: A a roadmap towards a circular economy and environmental sustainability via effective management strategies for plastic wastes Implementation of an analytical hierarchy process for developing better waste collection systems, and chemical recycling of plastic waste for sustainable development Mechanisms, perspectives, and challenges for natural biodegradation of plastic wastes, and conversion of plastic wastes into value added materials Plastic wastes management and disposal in developing countries, and challenges and strategies for plastic waste management during and post COVID-19 pandemic Plastic Waste Management is a highly valuable resource for scientists and researchers working in the fields of environmental science, environmental engineering, and plastic engineering towards the goal of developing sustainable materials, along with graduate and postgraduate students in related programs of study, and professionals and engineers in related industries.
