Wastes: Solutions, Treatments and Opportunities III contains selected papers presented at the 5th edition of the International Conference Wastes: Solutions, Treatments and Opportunities, that took place on 3-6 September 2019, in Costa da Caparica, Portugal. The Wastes conference, which takes place biennially, is a prime forum for sharing innovation, technological development and sustainable solutions for the waste management and recycling sectors around the world, counting with the participation of experts from academia and industry. The papers included in this book cover a wide range of topics, including: Wastes as construction materials; Wastes as fuels; Waste treatment technologies; MSW management; Recycling of wastes and materials recovery; Environmental, economic and social aspects in waste management; Life cycle assessment; Circular economy and wastes refineries; Logistics, policies, regulatory constraints and markets in waste management.

This volume focuses on the collection of waste and waste streams as an integral aspect of sustainable waste management. The authors take economic models and behavioral studies into account to go beyond just descriptions of waste collections technologies and collection route design. Models and tools for sustainable waste collection are described in detail, and the authors provide a comprehensive, integrated methodology to design waste collection systems that reduce environmental impacts, are economically viable, and achieve buy-in and participation from target populations. Part I of the book provides fundamentals and context on waste hierarchy, including waste prevention, reduction and reuse, waste collection itself, and steps such as preparation for recycling, recycling, treatment, and landfilling. Background in environmental, social, and economic concerns surrounding waste collection is also provided here. Part II addresses tools for design, operation, and maintenance of waste collection systems. Part III focuses on how the tools presented in Part II can be used to support sustainability assessments and decisions that consider the entire life cycle of waste and the role of waste collection programs in waste prevention, reduction, reuse, recycling, treatment, and disposal. Part IV addresses the challenges of developing sustainable waste management systems and addresses the role of waste collection in sustainable waste management in the future.

This book presents the application of system analysis techniques with case studies to help readers learn how the techniques can be applied, how the problems are solved, and which sustainable management strategies can be reached.

Valuable progress has been made in food packaging over the past two decades, reflecting advancements in process efficiency, improved safety and quality throughout the supply chain, and the need to reduce product loss and environmental impact. A new generation of food packaging systems, including active and intelligent packaging, is emerging, based on technological breakthroughs that offer the possibility of extending shelf-life, reducing food loss, and monitoring changes in the food product. Releasing Systems in Active Food Packaging closely examines such a technological breakthrough, active releasing systems, which add compounds such as antimicrobials, antioxidants, flavors, colorants, and other ingredients to packaged food products. Chapters detail examples of recent innovations in active releasing systems, and the authors systematically address their application to different food groups. Such an in-depth approach makes this a useful reference researchers, health professionals, and food and packaging industry professionals interesting in innovative food packaging technologies.
