Biogas from biomass appears to have potential as an alternative energy source, biomass resources being available worldwide. This is an overview of some salient points and perspectives of biogas technology. The current literature is reviewed regarding the ecological, social, cultural and economic impacts of biogas technology. This article gives an overview of present and future use of biomass as...

A system approach to biogas technology from "Biogas technology: a training manual for extension" (FAO/CMS, 1996) Biogas technology is a complete system in itself with its set objectives (cost effective production of energy and soil nutrients), factors such as microbes, plant design, construction materials, climate, chemical and microbial characteristics of inputs, and the interrelationships amo...

The paper presents the internet tool for decision support and data acquisition for Polish biogas market. This system helps investors to plan the size and potential power of biogas plant with usage of selected, own substrates. Because of open access via internet, the BiogasWebPlanner® allows to create one of the biggest database about future Polish biogas market.

The retention of copper (Cu) in saline–alkali soil (SAS) during long-term application biogas residue (BR) with a high concentration Cu raises concerns. In this work, the fate was detected using adsorption isotherms, scanning electron microscope—energy dispersive spectrometer, Fourier transform infrared X-ray diffraction, isothermal titration calorimetry, photoelectron spectroscopy, and microzon...

The optimization of full-scale biogas plant operation is of great importance to make biomass a competitive source of renewable energy. The implementation of innovative control and optimization algorithms, such as Nonlinear Model Predictive Control, requires an online estimation of operating states of biogas plants. This state estimation allows for optimal control and operating decisions accordi...

Knowledge of the microbial consortia participating in the generation of biogas, especially in methane formation, is still limited. To overcome this limitation, the methanogenic archaeal communities in six full-scale biogas plants supplied with different liquid manures and renewable raw materials as substrates were analyzed by a polyphasic approach. Fluorescence in situ hybridization (FISH) was ...

Batch experiments to remove ammonia from food waste digestate were set up, and preliminary runs undertaken. These experiments were based on gas stripping in a heated column reactor; the effects of different temperatures (35, 55 and 70 degrees C) and gas flow rates (0.125, 0.250 and 0.375 L(biogas)L(digestate)(-1)min(-1)) were considered using biogas as the stripping gas. At 35 degrees C, an inc...

The current work focuses on the generating bio-gas from food waste produced by Mahendra Engineering College Canteen using anaerobic digestion process. Attempts have been made to optimize various parameters in order to determine the most favorable recipe for maximum biogas production from the digested food waste. The biogas yields have been determined using batch anaerobic thermophilic digestion...

The presented contribution reviews actual status of biogas production in the European countries with a focus on the Slovak municipal WWTPs. In 49 monitored Slovak WWTPs (out of 520) the anaerobic digestion with biogas production is operated. The total volume of digestion tanks is about 195 000 m3 but the total daily biogas production is only approx. 55 000 m3 d–1. From a technological point of ...

Sludge is a byproduct of wastewater processing suitable for biogas production. The biogas consisting of about 60% methane can be used to generate electricity and heat. A data-driven approach for optimization of biogas production process in a wastewater treatment plant is presented. The process model is developed using routinely collected data categorized as controllable and uncontrollable varia...
