Download or read book Food Waste to Green Fuel Trend Development written by Neha Srivastava and published by Springer Nature. This book was released on 2022-05-17 with total page 282 pages. Available in PDF, EPUB and Kindle. Book excerpt: This edited book covers all the existing possibilities of using food waste as a potential, alternative and ‘ready to use’, feed stock for biofuels production. Moreover, it also presents all the sustainable and economically feasible biofuels option with their details strategies, mechanism, advantages, draw backs and future scope. It also explores in depth knowledge of food waste, and details the processing as well as opportunities to utilize it at for mass scale biofuels production. The practical feasibility and economic sustainability of biofuels production is still suffering with its cost intensity and lack of rigorous scientific strategies as well as inputs to explore it on further at upscale level. Low cost, carbon rich, economic and environmental friendly feedstock, may have strong possibilities to reduce the overall biofuels production cost and the book is based on this strategy. The book is of interest to academicians and researchers interested in industries related to biofuels production, food processing industries and industries related to waste valorization.
Download or read book Current Advances in Anaerobic Digestion Technology written by Marcell Nikolausz and published by MDPI. This book was released on 2021-03-17 with total page 230 pages. Available in PDF, EPUB and Kindle. Book excerpt: Anaerobic digestion (AD) is one of the oldest biotechnological processes and originally referred to biomass degradation under anoxic conditions in both natural and engineered systems. It has been used for decades to treat various waste streams and to produce methane-rich biogas as an important energy carrier, and it has become a major player in electrical power production. AD is a popular, mature technology, and our knowledge about the influencing process parameters as well as about the diverse microbial communities involved in the process has increased dramatically over the last few decades. To avoid competition with food and feed production, the AD feedstock spectrum has constantly been extended to waste products either rich in recalcitrant lignocellulose or containing inhibitory substances such as ammonia, which requires application of various pre-treatments or specific management of the microbial resources. Extending the definition of AD, it can also convert gases rich in hydrogen and carbon dioxide into methane that can substitute natural gas, which opens new opportunities by a direct link to traditional petrochemistry. Furthermore, AD can be coupled with emerging biotechnological applications, such as microbial electrochemical technologies or the production of medium-chain fatty acids by anaerobic fermentation. Ultimately, because of the wide range of applications, AD is still a very vital field in science. This Special Issue highlights some key topics of this research field.

Download or read book Anaerobic Co Digestion of Lignocellulosic Waste written by Luis Isidoro Romero García and published by MDPI. This book was released on 2021-09-02 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: Some terms, such as eco-friendly, circular economy and green technologies, have remained in our vocabulary, because the truth is that mankind is altering the planet to put its own subsistence at risk. Besides, for rationalization in the consumption of raw materials and energy, the recycling of waste through efficient and sustainable processes forms the backbone of the paradigm of a sustainable industry. One of the most relevant technologies for the new productive model is anaerobic digestion. Historically, anaerobic digestion has been developed in the field of urban wastes and wastewater treatments, but in the new challenge, its role is more relevant. Anaerobic digestion is a technologically mature biological treatment, which joins bioenergy production with the efficient removal of contaminants. This issue provides a specialized, but broad in scope, overview of the possibilities of the anaerobic digestion of lignocellulosic biomass (mainly forestry and agricultural wastes), which is expected to be a more promising substrate for the development of biorefineries. Its conversion to bioenergy through anaerobic digestion must solve some troubles: the complex lignocellulosic structure needs to be deconstructed by pretreatments and a co-substrate may need to be added to improve the biological process. Ten selected works advance this proposal into the future.

Download or read book Anaerobic Digestion of Food and Vegetable Waste written by Ying Jiang and published by . This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Food and vegetable wastes contribute a large percentage of the organic fraction of municipal solid waste (OFMSW), and anaerobic digestion potentially offers an ideal method for their management. Their chemical composition can, however, lead to unstable operation and in extreme cases complete process failure has been reported with this type of substrate. Semi-continuous trials on vegetable waste were carried out in laboratory-scale digesters with daily feed additions at different organic loading rates (OLR). At an OLR of 2g volatile solids (VS) 1-1 day-1 the methane yield was 0.345 1g-1 VS added, or 99% of that found in a biochemical methane potential (BMP) test. Higher OLRs led to reduced methane yield and energy conversion efficiency and to a drop in digester pH which could not be effectively controlled by alkali additions. To maintain digester stability it was necessary to supplement with additional trace elements including tungsten, which allowed OLR of up to 4g VS 1-1 day-1 to be achieved. Stability was also improved by the addition of yeast extract (YE). Co-digestion with card packaging and cattle slurry proved an effective means of restoring and maintaining stable operating conditions. Digesters fed on source segregated domestic food waste showed a long term pattern of failure as a result of the build-up of ammonia in the digester and the accumulation of volatile fatty acids, in particular propionic acid. The research gathered evidence to link this to an enzyme deficiency which was caused by a lack of selenium, or possibly other trace elements. Results from a fractional factorial designed batch experiment showed the importance of Se in the degradation of propionic acid, and indicated that Mo and Co might also play a role in this respect. Semi-continuous trials using laboratory-scale digesters also confirmed the requirement for Se which proved to be essential for both propionate oxidation and syntrophic hydrogenotrophic methanogenesis. Supplementation with Se allowed the digesters to operate at substantially higher OLR. At high loadings cobalt also becomes limiting, due to its role either in acetate oxidation in a reverse Wood-Ljungdahl pathway or in hydrogenotrophic methanogenesis. Critical Se and Co concentrations were established as 0.16 and 0.22mg kg-1 fresh matter feed at moderate loading. At this dosage the OLR could be raised to 5g VS 1-1 day-1 with specific and volumetric biogas productions of 0.75m3 kg-1 VS added and 3.75m3 m-3 day-1 at a standard temperature and pressure (STP) of 0°C and 101.325 kPa, representing a significant increase in process performance and operational stability. A tracer experiment using a radio-labelled isotope [2-14C] of acetate proved that under high ammonia concentrations, hydrogenotrophic methanogenesis was the dominant pathway leading to methane production in food waste digesters. A rapid non-derivatisation gas chromatographic method for quantification of palmitic, stearic and oleic acids was developed. These long chain fatty acids (LCFA) can accumulate in anaerobic digesters, and a simple extraction method was also developed to permit a more rapid sample turn-around time. The method was tested on digestate from food waste digesters. It was observed that the concentrations of stearic and palmitic acid in digesters routinely supplemented with trace elements were proportionally lower with respect to their relative loading when compared to those without supplementation. It was concluded that both Se and Co were deficient in source segregated domestic food waste collected in the UK, and that supplementation with these elements could improve digestion stability, allow higher OLR to be applied, and in doing so improve the energy yield of the digestion process.
