The paper presents the design idea of utilization of landfill gas to generate electricity at the Regional Center for Waste Management "DUBOKO". This process is becoming increasingly popular because it provides a convenient way of converting the waste to electrical energy, thereby reducing the amount of waste and the use of biogas for energy purposes, whilst also not increasing the amount of CO2 in the atmosphere. Although combustion of biogas, as well as natural gas, leads to the creation of a certain amount of carbon dioxide (CO2), carbon in biogas comes from the plant mass, which incorporated carbon from atmospheric carbon dioxide. Therefore, the use of biogas is viewed as CO2-neutral and does not affect the increase in the amount of greenhouse gases. The further conclusion is that any substitution of fossil fuels by biogas leads to a reduction in CO2 emissions.The book also contains tables for research on the amount of landfill gas that will be created in the future and its possible exploitation.
The cooking is an integral part of an every human being and food is the basic need for the living. Firewood, crop residue, cow dung cake, kerosene, electricity, biogas and LPG are commonly used as energy source for cooking. This work is an attempt to develop a solar cooker to use in kitchen and solar heat energy is transferred by servothermic (thermic) fluid. The details of the design and development of the solar cooker using thermic fluid was carried out. The performance evaluation of cooker also carried out and compared with the performance of the other types of the solar cookers. It has been observed that the energy conversion efficiency of cooker is somewhat lower but the inconvenience of using outdoor solar cooker and indoor air pollution by using other fuel cooking systems can be avoided.
This book presents the state of the art in biogas production using anaerobic digestion technology, with an emphasis on waste utilization/valorization. Offering a comprehensive reference guide to biogas production from different waste streams, it covers various aspects of anaerobic digestion technology from the basics, i.e., microbiological aspects to prominent parameters governing biogas production systems, as well as major principles of their operation, analysis, process control, and troubleshooting. Written and edited by internationally recognized experts in the field of biogas production from both academia and industry, it provides in-depth and cutting-edge information on central developments in the field. In addition, it discusses and reviews major issues affecting biogas production, including the type of feedstock, pretreatment techniques, production systems, design and fabrication of biogas plants, as well as biogas purification and upgrading technologies. 'Biogas: Fundamentals, Process, and Operation' also addresses the application of advanced environmental and energy evaluation tools including life cycle assessment (LCA), exergy, techno-economics, and modeling techniques.
In Palestine, there are huge natural possibilities in the field of bio-energy, which greatly reduces dependence on imports. In the field of bio-energy, there are huge amounts of solid waste produced by municipalities, which spend large sums of money to bury them in waste dumps, which are deficient and inadequate to meet the needs, there is a large amount of waste oil used and polluting the environment. There are also large quantities of olive peats that pollute the environment. Investment in these fields produces large amounts of energy and protects the environment from severe damage. In addition, there are huge quantities of animal manure from goats, chickens and cows, which can generate energy. In any case, bio-energy processes lead to the production of natural fertilizers that are desirable to farmers because of their lack of odors. The amount of biogas that can be extracted from organic waste, depends on the waste itself and the design of the digester system, it ranges from 20 m3 per ton to 800 m3 of biogas per ton. Each cubic meter (m3) of biogas contains the equivalent of 6kWh of calorific energy.
The use of environmental and nutritional factors to optimize fermentation conditions, are important for application of bioprocesses. To optimize these processes using conventional techniques, for example the one factor at a time method, is time consuming and laborious. Statistical design of experiments has become popular for medium optimization in industries since this allows the investigator to assess more than one factor at a time. This method is a time saving and effective method for screening significant factors of a multivariable system. This book reviews the latest research on statistical optimization of total biogas produced by Clostridium beijerinkii and Clostridium paraputrificum utilizing N-acetylglucosamine. Individual chapters cover different stages in the optimization design. The Plackett and burman screening design was used to identify significant medium constituents. The information gathered from each stage of the optimization process was used for the next stage of optimization. In addition to presenting recent research in this area, this book also contains important discussions on the potential benefits of using statistical optimisation designs.
