From Waste to Value Book Review:

From Waste to Value investigates how streams of organic waste and residues can be transformed into valuable products, to foster a transition towards a sustainable and circular bioeconomy. The studies are carried out within a cross-disciplinary framework, drawing on a diverse set of theoretical approaches and defining different valorisation pathways. Organic waste streams from households and industry are becoming a valuable resource in today’s economies. Substances that have long represented a cost to companies and a burden for society are now becoming an asset. Waste products, such as leftover food, forest residues and animal carcasses, can be turned into valuable products such as biomaterials, biochemicals and biopharmaceuticals. Exploiting these waste resources is challenging, however. It requires that companies develop new technologies and that public authorities introduce new regulation and governance models. This book helps policy-makers govern and regulate bio-based industries, and helps industry actors to identify and exploit new opportunities in the circular bioeconomy. Moreover, it provides important insights for all students and scholars concerned with renewable energy, sustainable development and climate change.

Food Wastage Footprint Book Review:

FAO estimates that each year, approximately one-third of all food produced for human consumption in the world is lost or wasted. This food wastage represents a missed opportunity to improve global food security, but also to mitigate environmental impacts and resources use from food chains. Although there is today a wide recognition of the major environmental implications of food production, no study has yet analysed the impacts of global food wastage from an environmental perspective. This FAO study provides a global account of the environmental footprint of food wastage (i.e. both food loss and food waste) along the food supply chain, focusing on impacts on climate, water, land and bio-diversity. A model has been developed to answer two key questions: what is the magnitude of food wastage impacts on the environment; and what are the main sources of these impacts, in terms of regions, commodities, and phases of the food supply chain involved - with a view to identify "environmental hotspots" related to food wastage. The scope of this study is global: the world has been divided in seven regions, and a wide range of agricultural products - representing eight major food commodity groups - has been considered. Impact of food wastage has been assessed along the complete supply chain, from the field to the end-of-life of food. The global volume of food wastage is estimated to be 1.6 Gtonnes of "primary product equivalents", while the total wastage for the edible part of food is 1.3 Gtonnes. This amount can be weighed against total agricultural production (for food and non-food uses), which is about 6 Gtonnes. Without accounting for GHG emissions from land use change, the carbon footprint of food produced and not eaten is estimated to 3.3 Gtonnes of CO2 equivalent: as such, food wastage ranks as the third top emitter after USA and China. Globally, the blue water footprint (i.e. the consumption of surface and groundwater resources) of food wastage is about 250 km3, which is equivalent to the annual water discharge of the Volga river, or three times the volume of lake Geneva. Finally, produced but uneaten food vainly occupies almost 1.4 billion hectares of land; this represents close to 30 percent of the world's agricultural land area. While it is difficult to estimate impacts on biodiversity at a global level, food wastage unduly compounds the negative externalities that monocropping and agriculture expansion into wild areas create on biodiversity loss, including mammals, birds, fish and amphibians.

Out of Sight Out of Mind Book Review:

A rising demand for healthy and sustainably grown food has become a trend of our time. However, there is dissonance in contemporary awareness about where food comes from and where it ultimately ends up. Globally, one third of all food produced is never used. In the United States alone, approximately 55 million tons of food is discarded each year (Venkat, 2012). This is problematic because food waste has environmental, economic and social costs associated with it. Organic materials accelerate anthropogenic climate changing greenhouse gas emissions by releasing methane as they decompose in landfills. In addition, unused food embodies and thus wastes valuable resources in its harvesting, processing and distribution including but not limited to land, water, energy and capital. Food waste has become a function of food security. Countries with the greatest access to food are those that also waste the greatest percentage of food. The primary goal of this research is to investigate and analyze key driving forces (e.g. the attitudes, beliefs, behaviors, socio-economic influences, management practices) that lead to post-consumer, household food waste for the case of Arcata, CA. The purpose of this research is to provide analysis that will serve as a community-development resource for motivating more conservative sustainable food waste behaviors and advance management practices in this rural community. My research draws upon environmental psychology for researching the attitudes, beliefs, behaviors and management of food waste in this community. Data was collected using a mixed-method approach including: primary research consisting of semi-structured interviews, community surveys and participant observation coupled with secondary research analysis of peer-reviewed papers, published reports and published data. The case study revealed the challenges of food waste management in rural areas, such as Arcata. In addition, the survey results highlighted common household behaviors and challenges that lead to food waste. In combination the interviews and survey outcomes elucidated plausible opportunities for sustainable food waste management.

Food Waste Reduction and Valorisation Book Review:

This book adds a new dimension to the sustainability assessment of food waste reduction and valorisation: policy analysis. Featuring a transdisciplinary analysis by key experts in the field, it identifies the drivers of change in food-waste reduction and valorisation technologies by looking, for example, at the regulatory framework and at policy actions undertaken by local and global actors. The book explores the development of regulations and policies for food-waste prevention, management, and valorisation at a global as well as European Union level. It also discusses the notion of food waste in legal terms and investigates the effects of the lack of a standard, universal definition of food waste on the efficient use of by-products, promising processes and products for technological and commercial exploitation. Utilising mathematical mapping methods to assess food consumption impacts and providing supply chain models that allow the testing of consumption scenarios, the book goes on to discuss a series of emerging technologies (tested at lab scale and/ or pilot scale) and opportunities for the valorisation of food waste.

Sustainable Bioconversion of Waste to Value Added Products Book Review:

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.

A National Strategy to Reduce Food Waste at the Consumer Level Book Review:

Approximately 30 percent of the edible food produced in the United States is wasted and a significant portion of this waste occurs at the consumer level. Despite food's essential role as a source of nutrients and energy and its emotional and cultural importance, U.S. consumers waste an estimated average of 1 pound of food per person per day at home and in places where they buy and consume food away from home. Many factors contribute to this wasteâ€"consumers behaviors are shaped not only by individual and interpersonal factors but also by influences within the food system, such as policies, food marketing and the media. Some food waste is unavoidable, and there is substantial variation in how food waste and its impacts are defined and measured. But there is no doubt that the consequences of food waste are severe: the wasting of food is costly to consumers, depletes natural resources, and degrades the environment. In addition, at a time when the COVID-19 pandemic has severely strained the U.S. economy and sharply increased food insecurity, it is predicted that food waste will worsen in the short term because of both supply chain disruptions and the closures of food businesses that affect the way people eat and the types of food they can afford. A National Strategy to Reduce Food Waste at the Consumer Level identifies strategies for changing consumer behavior, considering interactions and feedbacks within the food system. It explores the reasons food is wasted in the United States, including the characteristics of the complex systems through which food is produced, marketed, and sold, as well as the many other interconnected influences on consumers' conscious and unconscious choices about purchasing, preparing, consuming, storing, and discarding food. This report presents a strategy for addressing the challenge of reducing food waste at the consumer level from a holistic, systems perspective.

Resource Recovery from Waste Book Review:

Humans generate millions of tons of waste every day. This waste is rich in water, nutrients, energy and organic compounds. Yet waste is not being managed in a way that permits us to derive value from its reuse, whilst millions of farmers struggle with depleted soils and lack of water. This book shows how Resource Recovery and Reuse (RRR) could create livelihoods, enhance food security, support green economies, reduce waste and contribute to cost recovery in the sanitation chain. While many RRR projects fully depend on subsidies and hardly survive their pilot phase, hopeful signs of viable approaches to RRR are emerging around the globe including low- and middle-income countries. These enterprises or projects are tapping into entrepreneurial initiatives and public ̶ private partnerships, leveraging private capital to help realize commercial or social value, shifting the focus from treatment for waste disposal to treatment of waste as a valuable resource for safe reuse. The book provides a compendium of business options for energy, nutrients and water recovery via 24 innovative business models based on an in-depth analysis of over 60 empirical cases, of which 47 from around the world are described and evaluated in a systematic way. The focus is on organic municipal, agro-industrial and food waste, including fecal sludge, supporting a diverse range of business models with potential for large-scale out-and up-scaling.

Evaluation of Alternative Valorization Options for Institutional and Industrial Food Wastes Book Review:

"In recent years many countries and several regions in the United States have passed legislation on banning landfilling of organic waste. It is a well-known fact that organic wastes, including food scraps, generate methane under anaerobic landfill environments and contribute significantly to global warming. As more regions are mandated to follow the landfill ban, there is an increasing demand for alternative technologies for the disposal, treatment and upcycling of food wastes. Disposal and treatment may not result in any value-added products and hence are not the most efficient ways to manage food waste. As food waste has a high energy value due to the presence of organic nutrients, it can be a suitable resource to generate energy, fuels, chemicals, and materials through ‘valorization’ technologies. Therefore, to proactively address food waste management issues in the future, this dissertation evaluated three alternative food waste valorization options for institutional (food scraps) and industrial food wastes. First, the food scraps and industrial food wastes were characterized for their chemical composition such as organic and inorganic nutrients. The objectives of this study were to (a) provide a detailed database on chemical characteristics of food scraps and industrial food wastes based on in-house laboratory measurements, third-party analysis, and literature data; (b) analyze the data obtained to understand the variability in characteristics between different sources of food waste. The outcomes of this chapter resulted in a comprehensive data collection and statistical analysis for food scraps from various sources and 10 different industrial food waste streams. The developed data inventory is useful to anyone who does not have resources to carry out food waste characterization and researchers who work on food waste modeling studies. Second, the process issues related to anaerobic digestion of food scraps were address using an experimental study. Process instability is a major issue in food scrap digestion at higher organic loading rates, and often leads to digester failure. The objectives of this study were to (a) study the effect of increasing organic loading rate on the stability of the process by monitoring several process parameters, and (b) offer a solution to the instability issues using an unconventional co-digestion approach. The experiments were carried out in semi-continuous mode with a daily feeding cycle to mimic the real-world conditions as closely as possible. Process parameters such as pH, volatile fatty acids, alkalinity, ammonia, biogas production, methane and hydrogen sulfide content of biogas were monitored on a regular basis. Results of this experiment provided useful information for digester operation on the threshold levels of various process parameters to that would help avoid a digester failure. Co-digestion of food scraps with other food sector wastes such as acid whey, wasted bread and soiled paper napkins were proven to significantly improve process stability and helped achieve high organic loading rate during the digestion of food scraps. These results are useful in the operation of non-farm digesters where conventional co-substrates (such as animal manure) are not available or not practical to haul. Third, the use of fermentation technology in food waste management was evaluated for its technological feasibility. While anaerobic digestion is a well-developed technology for organic waste management with a few processes issues related to food scrap digestion, the use of fermentation in food waste management is not well documented. Food waste fermentation to produce value-added fuels and chemicals is taking shape only in recent years. The objective of this work was to provide ‘state-of-the-art’ knowledge on fermentation of food wastes in the production of products, specifically ethanol, 1-butanol, iso-butanol, and organic acids using experimental and published data. With a combination of experimentally obtained and previously published studies, a matrix was developed that maps the suitability of producing either alcohols or organic acids from various food wastes. The outcomes of this study provided a contemporary knowledge on the research status related to food waste fermentation. Also, the types of food wastes that can be potential feedstocks for fermentation to produce ethanol, butanol, lactic acid and succinic acid were suggested through the developed matrix. The outcomes from this work provide useful qualitative information to the growing number of businesses in the waste management world looking for newer and more efficient options for food waste valorization. Finally, the potential of thermochemical conversion as a food waste management strategy was explored using an exergy analysis and life cycle thinking approach. Use of thermochemical processing to produce a soil amendment called biochar is a circular economy inspired approach and needs evaluation as there is a limited number of research studies in this area. The objectives of this study were to (a) produce biochar using a small-scale commercial thermochemical processing unit and characterize the biochar for elemental composition, (b) estimate the exergy efficiency of various scenarios, and (c) estimate the global warming potential (GWP) by expanding the system boundary to use biochar as a soil amendment. Based on these results, the most practical options for management of food waste were recommended to produce biochar or thermal energy. The exergy analysis combined with GWP potential estimations can assist operators of thermochemical conversion systems to decide upon the practical operating conditions, and policy makers to consider and regulate newer technologies for food waste management."--Abstract.
