Hydrothermal carbonization (HTC) is recently promoted as an upgrading technology for highly wet streams such as digestate from biogas plants, sewage sludge, and other waste biomass. It converts raw feedstock into a coal-like product known as hydrochar. The resulting hydrochar has fuel characteristics similar to lignite coal, potential for soil amendment, or for material use. Besides the solid phase, HTC further yields a highly contaminated waste water, which cannot be released to the environment without further processing. The aim of this study is to analyze the feasibility of treating HTC waste water by anaerobic digestion (AD). First of all, the general AD feasibility and long-term stability of HTC waste water as a sole substrate is tested by experimental means. Hereby, the focus is placed on AD process performance and potential inhibitory effects. Furthermore, the study includes the economic and energetic assessment of an industrial-scale HTC plant supplemented by anaerobic waste water treatment.

Biodiesel is receiving increased attention as an alternative, non-toxic, biodegradable and renewable diesel fuel. Biodiesel comes in use due to depletion of petroleum fuels and the environment benefits. Biogas can also be used with the biodiesel in I.C engine because of its better mixing ability and clean burning nature with very minor modifications in the engine. The usage of oxygenated fuels can reduce the particulate matter (PM) emissions from the engine without large modification of the engine. The present study has conducted to evaluate the properties of rice bran biodiesel and effect on the performance and emissions characteristics of C.I. engine using rice bran oil methyl ester with oxygenated fuel of Diethyl Ether blended with diesel as a pilot fuel and biogas as a gaseous fuel under dual fuel mode. This study is conducted in two phases. In the first phase, the blends of D80-B10-DEE10 and D60-B20-DEE20 with the use of biogas at a fixed flow rate of 0.9 kg/hr are performed at different load conditions and compared with diesel. In the second phase, the blends of D80-B10-DEE10 and D60-B20-DEE20 are performed at different load conditions.

Anaerobic codigestion of municipal wastewater sludge and restaurant grease was investigated in a semi-continuous lab-scale digestion experiment under mesophilic condition (37 °C). Compared to the control digester, COD loading rate for test digester was elevated to 387% (organic loading rate 4.235 kgVS/m3/d) and led to 467% increase in daily biogas production, 25.2% increase in methane yield (based on VS deduction), 29.8% increase in COD reduction rate and 27.2% increase in VS reduction rate, respectively. Methane content ranged from 62% to 67%. There was no negative effect of grease addition on the digester performance in this experiment. The great increases in biogas production and methane yield indicated enhanced digestion performance. In addition, partial alkalinity and pH proved to be good indicators to monitor digestion process and predict overloading. It is still possible to keep increasing organic loading by the addition of more grease, but according to monitoring results, the system was close to overloading.

The availability of potable water is receding due to the discharge wastewater from industrial sector. Purification and recycling of wastewater have been made mandatory. Anaerobic technology is the most versatile option for treating high-strength organic wastewater. The book describes the treatment of synthetic starch containing wastewater of high COD in an anaerobic tapered fluidized bed bioreactor which reduced the wash out of the biomass. Mesoporous Activated Carbon (MAC) was used as a carrier matrix to improve the efficiency through insitu immobilization of anaerobic bacteria and caused internal micro agitation due to entrapped gases. The effect of parameters viz., temperature, pH, BOD, COD, biogas, total VFA and its composition, alkalinity, ORP, bed height and superficial velocities on the performance of the reactor is discussed. The COD removal efficiency is 92% in the reactor. The book includes preparation and characterization of MAC, optimization of the reactor and kinetic study for different start-up under transient conditions. Further a mathematical model for the prediction of the output values using different neural network techniques is developed.

Declining viability of biogas production followed by a stagnation of dissemination of biogas plants calls for new repowering measures as increased amounts of storable energy sources from biomass are required for providing a smooth integration of fluctuating renewable energy sources in the electricity market in future.The implementation of biogas microgrid concepts as a repowering measure allows for a combination of organizational and technological efficiency increase as a result of decoupling of biogas production from utilization.The first objective of the present work is the development of a tool for techno-economic assessment of biogas microgrid configurations .The second objective of the work is the application of the tool for assessing the concepts’ potential for efficiency increase based on its unique features: gas storage and gas transport. These features were assessed for the two most promising biogas utilization pathways being bio-methane production and flexible electricity generation from biogas.The tool is an Excel© based model where biogas microgrid relevant processes such as drying, desulphurization, compression but also the upward and downward processes of biogas production such as biomass transport and electricity generation/methanization are described with mathematical-physical equations. Based on the latter, calculations related to energetic performance and storage capacity are preformed. The economic assessment is based on the annuity method .The fixed costs of the biogas microgrid components are expressed as functions of scale (capacity).The techno-economic calculations are preformed in three modules. The modularity of the tool allows for flexible adjustment of selected biogas microgrid configurations to various local conditions. Consequently the configuration can vary in following parameters: (a) length, (b) substrate type, (c) number and (d) capacity of connected biogas plants, (e) grid structure and (f) biogas utilization pathway.

The present book is a result of experimental work carried out on a spark- ignition engine fueled with Bio-gas. The biogas was obtained by the anaerobic digestion of Gobar(Cow-Dung). The investigations are made to determine the difference in the performance of the engine due the the purification of raw bio-gas. It is a good work carried out by the author which can further be studied by using various other biogas cleaning methods.
