Preface

The world is currently experiencing increased environmental contamination with solid waste, which is one of the greatest environmental threats today. As such, this book provides guidance on treating this problem that requires the synergistic action of the scientific community.

The development and application of approaches and technologies that provide economic and safe management of such type of waste is an essential issue in the treatment and disposal of solid wastes.

In this book, the authors summarize their experience and present advances related to assessing the strategies of sustainable solid waste management. The book contains ten chapters, organized into four sections that cover important research aspects of solid waste management technologies. The first section includes the introductory chapter prepared by the editor to present a brief background on solid waste. The second section begins with the chapter "Reflections on the Influence of Family Demographics on Food Waste Generation among the City of Tshwane Households, Republic of South Africa," in which the authors investigate the influence of household demographics on food waste generation in the Republic of South Africa. The chapter "Sustainable Pathway for Closing Solid Waste Data Gaps: Implications for Modernization Strategies and Resilient Cities in Developing Countries" addresses three peculiar challenges in solid waste management systems of developing countries.

The third section contains chapters "Guide for Organising a Community Clean-up Campaign", "Economics of Solid Waste Management: A Review", "Sustainable Solid Waste Management in Morocco: Co-Incineration of RDF as an Alternative Fuel in Cement Kilns", "Effectiveness of Anaerobic Technologies in the Treatment of Landfill Leachate" and "Hydrometallurgical Recovery of Gold from Mining Wastes".

The final section of the book includes chapters "Bioelectricity from Organic Solid Waste" and "Agricultural Solid Wastes: Causes, Effects, and Effective Management".

The editor wishes to thank all the participants in this book for their valuable contributions. Thanks also go to the staff at IntechOpen, particularly Author Service Manager Ms. Dolores Kuzelj, for her continuous assistance in finalizing this work.
