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.

Urban sustainability is a subject of recent focus in North America, and Canada specifically. As our urban areas continue to grow and consume large quantities of energy and produce massive amounts of waste, we are faced with the challenge of how to manage this situation in a way which is both responsible and sustainable. One feasible urban waste-to-energy technology is anaerobic digestion. Anaerobic digestion (AD) has been a usable energy source for over 100 years and is currently being employed in countries around the world in rural settings to generate electricity and heat, but it has yet to make a large migration to the urban environment though it is a viable and mature process. Applied to the organic waste produced in urban environments, anaerobic digestion could provide a critical solution to growing garbage problems while simultaneously reducing external energy requirements. The cost of transporting waste outside of cities to landfills will continue to rise and if a substantial portion of this waste could be retained, digested, reduced, and converted into useable energy in the urban environment, then this is something to be seriously considered. The goal of this thesis is to investigate the feasibility of power and energy generation through the use of anaerobic digestion of food waste in the urban environment, suggest a novel modeling technique using the International Water Association's Anaerobic Digestion Model #1, and provide a case study from the downtown campus of Concordia University in Montreal, Canada.

Zambia is richly endowed with a wide range of biomass sources including woodlands, forests, agricultural residues and livestock waste. Biomass energy contributes supplies over 70 percent of the country’s energy needs. Due to the current extraction and consumption methods, the use of biomass energy has been linked with detrimental environmental effects such as deforestation and forest degradation as well as climate change, due to the loss of carbon sinks. Inefficient utilisation of biomass contributes significantly to deforestation which is estimated at between 79 000 – 150 000 ha per year, and negatively affects the health and income of rural households that depend on forest products for their livelihoods. Sustainable bioenergy strategies and alternative bioenergy solutions need to be defined and integrated into current efforts of the country to increase stable and sustainable access to energy. This report assesses the country context and defines which bioenergy options can be viable considering a number of solutions for electricity production, cooking fuels and transport fuels at the provincial and district level. Possible options originating from crop residues, livestock residues and forest plantation harvesting residues are identified, having netted out agriculture and forestry needs. The assessment now needs to be followed by local verification and investment to deploy an initial set of bioenergy projects and test the findings on the ground.

The purpose of the China Energy Technology Program (CETP) has been to take a holistic view of electricity generation in China with special emphasis on the economic and environmental impact of technology. The program is a collaborative effort involving industry, as leader and manager of the program; researchers from academia and national research institutes; and the stakeholders--users or planners of the electricity market. A power plant, no matter of what kind, is not a solitary unit, which may be considered independently from its environment. Modem society has been built on easy access to power; it is now asking for environmentally clean power. Clean power is the pathway that will lead to sustainability, an extension of the concept of an environmentally clean future. Progress toward a sustainable technical solution must include an evaluation of the environmental, economic, and societal impact of electrical power generation. To achieve the goals of the CETP program, we wanted to go beyond what had been done in similar programs in the past. Its organizers wanted the program not only to evaluate the overall impact of electricity generation, but also do it in such a way that program results could be applied and adapted to different circumstances, including countries other than China. For this purpose we have developed a methodology and presented it on a DVD disc, which the reader will find inside the back cover of this book. The methodology is conceived to allow insights into the function of the program on various levels.

"Every day, enormous quantities of nutritious food are wasted in landfills across the globe. Agriculture and food production use intensive amounts of water, chemicals, and land, rendering food waste as a major environmental and economic concern. New York State is currently considering legislation that would ban landfill disposal of food waste produced by large institutional generators, such as universities, hospitals, sports venues, restaurants, grocery stores, etc. Institutions have concentrated populations which generate predictable volumes of food waste and waste cooking oil. At the same time, these populations need heat, electricity, vehicle fuel, and soap. Developing a biorefinery system offers great potential to institutions and provides viable and sustainable utilization of various waste streams to generate energy via anaerobic digestion and biodiesel production process while simultaneously solving a waste disposal issue. However, the implementation of biorefinery systems at institutional food waste generators is just beginning, and data required to design the system and relevant case studies are very limited. Recognizing the urgent need to find alternatives for the diversion of food waste from landfills, this dissertation has provided the technical and economic viability of decentralized, onsite biorefinery systems at institutional generators with a specific focus on large institutions generating, on average, more than 1.8 metric tons of food waste per week (~91 t/year, equivalent to 100 short tons/year). The challenges and opportunities of these alternatives have also been considered in this dissertation. First, development of sustainable food waste management requires an integrated, interdisciplinary management structure which includes a good understanding of regional variations in food waste resources, waste treatment facilities and processing capacity in a specific geographic region. Currently, poor quality and unreliable data on food waste prohibits proceeding to efficient waste management. These scarcities of data have led to a call for further research. To identify the research gaps, Chapter 2 begins with an assessment of reliable data on the quantity and types of food waste produced, transport of waste to treatment facilities, location of existing waste treatment facilities, and the amount of wastes that could potentially be treated at these facilities. Regions 3 and 8, as defined by the New York State Department of Environmental Conservation (DEC), were chosen as case studies to the underlying challenges and potential opportunities. The information provided in this chapter can be an important resource for implementing future waste diversion strategies, and further indicate which policy attributes should be considered. In Chapter 3, an assessment was conducted of the technical challenges, economic feasibility and policy opportunities to adopt low-volume anaerobic digester (LVAD) systems, designated for deployment at the scale of an individual food waste generation site. Food waste generators often have much lower volumes of organic material available for conversion than dairy farms or public-owned treatment works (POTW). Small anaerobic digestion systems are not a new technology but have historically been implemented primarily in treating animal waste in developing countries. In the U.S., anaerobic digestion of food waste is usually achieved by co-digestion with dairy manure in centralized facilities, while food waste-only anaerobic digestion is still emerging and public data or case studies necessary to establish this as a potential food waste management pathway are lacking. Rochester Institute of Technology (RIT) was chosen as a case study to assess the viability of implementing an LVAD system utilizing campus organic waste. It was demonstrated that the LVAD approach is economically feasible only if several conditions are met: biogas is utilized directly for thermal energy applications, thereby eliminating the capital/operation/maintenance costs associated with electricity production; system capital cost is reduced to $500,000 or less; and available feedstock is increased to at least 900 t/year by importing food waste from neighboring generators and collecting associated tipping fees. Chapter 4 documents an investigation of various solution pathways available to utilize another important institutional food waste material: waste cooking oil (WCO). Institutions such as universities usually generate large amounts of waste cooking oil that can be suitable for production of biodiesel via the process of transesterification. The free fatty acid (FFA) content of waste cooking oil from institutional cafeterias is often lower than many other establishments (i.e., fast food restaurants), and thus has a greater value as a biodiesel feedstock, because the cooking oil replacement rate is often higher. The development of a closed-loop biodiesel production system, including utilization of crude glycerol as an ingredient for soap production, is compelling especially in a constrained system because the locations of WCO feedstock supply and biodiesel demand are in close proximity and controlled by a single entity. Biodiesel can be utilized by the RIT community in vehicles and other applications. Crude glycerol can be refined and used to produce soap of varying quality and has potential as a value-added product. Potentially, the soap could be used in cafeterias and bathrooms across campus and dining services. This study indicated that using waste cooking oil for biodiesel production at the institutional scale could only be viable by generating the revenue from the sale of biodiesel and offsetting the cost of high quality liquid soap at retail price. In Chapter 5, it was demonstrated that black soldier fly larvae (BSFL) could potentially reduce the amount of food waste needing to be landfilled in areas of concentrated generation, such as urban areas and institutions like universities and hospitals. BSFL have previously been used by home gardeners and large agricultural enterprises to transform food wastes and animal manures into feed for chickens or fish, while significantly reducing waste volumes. Bioconversion of food waste biomass with BSFL results in useful products such as protein rich insect biomass. This study demonstrated that bio-methane potentials (BMP) of BSFL were higher than the potential of food waste and manures and 1.5 to 2 times higher than other representative feedstocks, including energy crops and algae. In addition, the yield of biomass per hectare of land used is much higher. BSFL could therefore be a viable feedstock for biogas production or as part of an integrated biorefinery system, and as an effective bioresource solution for the global problem of food waste management. Finally, it is uncertain that an
