Food insecurity, hunger, and malnutrition affect all counties worldwide; one in nine people suffers from starvation and malnourishment. At the same time, one billion tonnes of food (17%) is wasted yearly, and associated environmental problems have become emerging global issues. There is an urgency to treat food waste as a resource. This timely volume comprises eighteen chapters dealing with different aspects of food waste treatment and management in different parts of the world (1). Food waste should be used for urban agriculture and landscaping (2). It is feasible to employ biochemical and thermochemical processes in treating and recovering food waste (3). A case study demonstrated such feasibility in Shenzhen, China's most developed city (4). The fundamentals, trends, and future opportunities for food waste composting and anaerobic digestion are explored (5, 6, 7). Food waste can be converted to single-cell protein (8), animal feeds (9), and fertilizer (via vermicomposting and anaerobic digestion) (10, 11). Various value-added products can be generated: chemicals, synthetic alternatives, nanocellulose, construction materials, and biodegradable fibres (12-16). Chinese herbal residues and brewery waste are examples of very specific wastes that could be valorised into value-added products (17, 18). Fundamental and wide-ranging attention is required towards sustainable food production and consumption through the entire global food supply chain. In the best-case scenario for changed management and behaviours, substantial amounts of surplus food and food waste will remain inevitable. This provides ample justification for this book on food valorisation through conversion to various value-added products. Contributions from a wide range of international experts draw attention to valuable, realistic, and exciting opportunities for science, business, and society that will also provide essential and substantial environmental benefits.

Bringing together the research of 62 distinguished scientists in one volume, Environmental Contamination: Health Risks and Ecological Restoration offers a comprehensive view of the remediation of contaminated land. A one-stop resource, it covers historical and emerging contaminants, the issues of bioavailability of chemicals and their associated human health risks, and the latest remediation technologies. The book also contains numerous case studies, many of them drawn from the Asia-Pacific region, that look at the effects of rapid industrialization. The chapters are inspired by presentations and discussions held during the 2010 Croucher Advanced Study Institute workshop, entitled Remediation of Contaminated Land-Bioavailability and Health Risk. With the speed and scale of recent socioeconomic development, particularly in regions with less stringent environmental regulations, it is evident that various industrial activities have given rise to tremendous environmental degradation and severe health problems. The book begins with a description of current problems and future trends of pollutants, as well as their impact on the environment and human health. It then focuses on emerging contaminants, such as flame retardants and electronic waste. The book also examines research on environmentally friendly and sustainable solutions to remediate contaminated lands, exploring cutting-edge bioremediation and phytoremediation technologies. Chapters discuss arsenic biomethylation, copper homeostasis, microbial transformation of phthalate esters, the potential function of paddy fields in phytoremediation, the use of constructed wetlands for pollution control, phytostabilization of arsenic-contaminated sites, and more. This timely book provides readers with a highly focused reference on some of the most urgent environmental and health issues and research topics. These include e-waste recycling and arsenic and heavy met
