“…AD produces energy in the form of biogas with the approximate composition of 55-70% CH 4 -30-45% CO 2 [7]. The biogas can be used for heating or electricity production, as well as for mobility after upgrading [8][9][10][11]. The AD technology has the potential for further improvement and application within the EU, as biogas can play a key role in the bioenergy field [12][13][14][15].…”

The goal of this research was to appraise the effect of combined inoculation on the performance of anaerobic digesters treating hardly degradable material, and particularly the pressed fine sieved fraction (PFSF) derived from wastewater treatment plants (WWTPs). Batch tests were conducted in mesophilic conditions in order to examine the optimal mixing ratio of inoculums. Mixing ratios of 100:0, 75:25, 50:50, 25:75, and 0:100 of three different inoculums were applied in the batch tests. The findings indicated that the inoculation of digested activated sludge with digested organic fraction of municipal solid waste (MSW) in the ratio 25:75 resulted in a higher PFSF degradation and a higher biogas yield. The results from the kinetic analysis fit well with the results from the batch experiment.

“…[77] Therefore, it is difficult to further increase the water permeability of these membranes without sacrificing rejection. [78,79] This is a direct consequence of the separation mechanism of thin-film composite membranes, where increasing selectivity to allow higher removal of ions will substantially reduce the membrane permeability and will increase energy consumption. Developing RO membranes with higher rejection without sacrificing water permeability will necessitate a major paradigm shift, as it will require membranes that do not follow the solution-diffusion mechanism.…”

“…FO energy consumption is low because it requires only stirring or pumping of the solutions involved. [87,88] The feasibility of a FO-MD hybrid system has been examined by concentrating solutions containing valuable industrial chemicals or pharmaceuticals. [89] Wang Minireview et al [90] employed a bench-scale FO-MD hybrid system to treat highly viscous protein solution.…”

Membrane engineering is one of the disciplines most involved in the technological innovations necessary to face the problems characterizing the world today and in future such as water shortage, raw material depletion, and energy consumption. Membrane operations contribute to solving these problems, and the potentialities of membrane operations have been widely recognized in the last few years. In this work, an overview of membrane applications and their perspectives in the field of membrane materials, membrane modelling and water treatment will be analyzed. The scope of this study is to show how membranes, membrane operations and their integration could contribute to the redesign of membrane engineering in the logic of the process intensif ication strategy.

“…In recent years, energy demands have increased rapidly all over the world and new technologies are required to address this issue [1][2][3][4][5][6]. The limitations of fossil fuel resources and their adverse effects on the environment have led to increasing interest in the use of renewable energy resources, including biogas, a combustible gas which mainly consists of methane and carbon dioxide [7][8][9][10][11][12][13][14].…”

Preliminary Assessment of a Biogas-based Power Plant from Organic Waste in the North Netherlands

Biogas is expected to play a crucial role in achieving the energy targets set by the European Union. Biogas, which mainly comprises methane and carbon dioxide, is produced in an anaerobic reactor, which transforms biomass into biogas. A consortium of anaerobic bacteria and archaea produces biogas during the anaerobic digestion (AD) of various types of feedstocks, such as animal slurries, energy crops, and agricultural residues. A biogas-fed gas turbine-generator and steam generator produce heat and power. In this study, a combined heat and power installation is studied. The biogas-based power plant treating cow manure, grass straw, and sugar beet pulp was examined using the software SuperPro Designer, and the obtained economic reports are evaluated. From the results, subsidy for electricity does not change the feasibility of the plants in case that cow manure or sugar beet pulp are used as feedstocks. The net present value (NPV) of biogas plants treating cow manure and sugar beet pulp was negative and the subsidy is not sufficient to make profitable these cases. The biogas power plant treating straw showed a positive net present value even without subsidy, which means that it is more desirable to invest in a plant that produces electricity and digestate from grass straw.
