The world population is expected to increase exponentially within the next decade, which means that the food demand will increase and so will waste production. There is a need for effective food waste management as wasted food leads to overutilization of water and fossil fuels and increasing greenhouse gas emissions from the degradation of food. Global Initiatives for Waste Reduction and Cutting Food Loss explores methods for reducing waste and cutting food loss in order to help the environment and support local communities, as well as solve issues including that of land space. Covering topics that include food degradation, enzymes, and microorganisms, this publication is designed for policymakers, environmentalists, engineers, government officials, researchers, scientists, academicians, and students.
This edited book discusses various processes of feedstocks bioconversion such as bioconversion of food waste, human manure, industrial waste, beverage waste, kitchen waste, organic waste, fruit and vegetable, poultry waste, solid waste, agro-industrial waste, cow dung, steroid, lignocellulosic residue, biomass, natural gas etc. Nowadays, the industrial revolution and urbanization have made human life comfortable. However, this requires excess usage of natural resources starting from food and food products, to energy resources, materials as well as chemicals. The excess use of natural resources for human comfort is expected to high fuel prices, decline natural resources as well as cause a huge hike in the cost of raw materials. These factors are pushing researchers to grow environmentally friendly processes and techniques based on inexpensive and sustainable feedstock to accomplish such worldwide targets. Bioconversion, otherwise called biotransformation, is the change of natural materials, for example, plant or animal waste, into usable items or energy sources by microorganisms. Bioconversion is an environmentally friendly benevolent choice to supplant the well-established chemical procedures utilized these days for the production of chemicals and fuels. A variety of alternatives advancements are being considered and are directly accessible to acquire diverse valuable end-products through bioprocesses. This book discusses in detail the process and techniques of bioconversion by focusing on the organic feedstock of animal and plant origin. It brings solutions to the bioconversion of various feedstock into value-added products.

In the past, food waste has been used to produce biogas and biofuels, fertilizers, and animal feed. Using it as a feedstock for innovative biorefineries is not only an ethical issue but also a smart application of the circular economy. This book explores the zero-waste concept in the thriving biobased sector, proposing technologies and procedures to meet the sustainable development goals. The volume categorizes food waste sources and proposes an impressive number of high value-added compounds (e.g., platform chemicals, enzymes, nutraceuticals, antioxidants, organic acids, phosphate, bioadsorbents, pectin, solvents, and pigments) that can be obtained in a sequential biocascade, via chemical, biochemical, thermal, and physical technologies. The synthesis of bioplastics from food waste, their copolymerization and blending, as well as the production of biocomposites and bionanocomposite with biofillers from food scraps, are presented: eluding the cost of waste disposal, reducing biobased materials price, and avoiding using edible resources as a starting material for biobased items are the main beneficial peculiarities of the process. The Authors illustrate challenging characteristics of new biobased materials, such as their mechanical and physico-chemical features, their biodegradability, compostability, recyclability, chemical compatibility, and barrier properties. The volume also delves into socioeconomic considerations and environmental concerns related to the upcycling of food waste, as well as the safety and life cycle assessment of biobased products. Finally, the authors address how advances in digital technology can make food waste upcycling a negative-cost process and discuss best practices to practically implement the biorefinery concept. Research gaps and needs are suggested, and recommendations for food waste handling and management during this COVID-19 pandemic are provided.
Food is a precious commodity and its production can be resource-intensive. According to the Food and Agriculture Organization of the United Nations, nearly 1.3 billion tons of food products per year are lost along the food supply chain, and in the next 25 years, the amount of food waste has been projected to increase exponentially. The management of food waste should follow certain policies based on the 3Rs concept, i.e., reduce, reuse, and recycle. Currently, most food waste is recycled, mainly as animal feed and compost. The remaining quantities are incinerated and disposed in landfills, causing serious emissions of methane (CH4), which is 23 times more potent than carbon dioxide (CO2) as a greenhouse gas and significantly contributes to climate change. Valorizing food waste components could lead to numerous possibilities for the production of valuable chemicals, fuels, and products. The present Special Issue compiles a wide spectrum of aspects of research and technology in the area of food waste exploitation, highlighting prominent current research directions in the field for the production of value-added products such as polylactic acid, hydrogen, ethanol, enzymes, and edible insects.
This book discusses one of the biggest challenges of the food industry, which is waste management. Food industries generate high amounts of waste, both solid and liquid, resulting from the production, processing and consumption of food. Stringent environmental legislators have made the task of waste management more challenging. Through the three sections of this book, the readers are introduced to the different types of wastes generated, utilization of waste through food processing industry and sustainable waste management technologies. The different chapters describe how the biomass and the valuable nutrients from food industry wastes could be used to develop value-added products. The book reiterates that food wastes and their by-products are an excellent source of sugars, minerals, dietary fiber, organic acids, bio active compounds such as polyphenols, carotenoids and phytochemicals etc. This book is an excellent resource for industry experts, researchers and students in the field of food science, food processing and food waste management.
