Opis:
Methane fermentation is one of the ways to obtain gaseous fuel from biomass. Agricultural and industrial products are used in this process. Various additives (biological and chemical substances) which can be used in the fermentation process may affect the quality of produced biogas. An analysis of the effect of inhibitors used in livestock production to improve the hygienic conditions of the environment where animals dwell was presented in the paper. These preparations have a significant influence on methane fermentation process and amount of obtained final product.
Fermentacja metanowa to jeden ze sposobów pozyskiwania paliwa gazowego z biomasy. W procesie tym wykorzystywane są produkty pochodzenia rolniczego i przemysłowego. Do procesu fermentacji można stosować różne dodatki (substancje biologiczne i chemiczne), które mogą wpływać na jakość wytworzonego biogazu. W pracy przedstawiono analizę wpływu inhibitorów stosowanych w produkcji zwierzęcej w celu poprawy stanu higienicznego środowiska, w którym bytują zwierzęta. Środki te mają istotny wpływ na proces fermentacji metanowej oraz ilość pozyskiwanego produktu finalnego.

Opis:
The declining quantity of fossil fuels and the increasing demand for energy are two of the many problems that are affecting current times. This is why there is an increasing interest in and introduction of operations related to renewable sources of energy. One of many such possibilities is to conduct the biomass methane fermentation process and to obtain clean energy in the form of biogas. The aim of this research was to analyse the biogas-generating potential (Biochemical Methane Potential) of out-of-date frozen products in the laboratory anaerobic fermentation process and the near-infrared method with appropriate Biochemical Methane Potential calibration. The results obtained showed that selected frozen products are an excellent material for use as substrates resulting in the production of high quality biogas. It gives the opportunity to continue research, mainly in terms of applications, e.g. for biogas plants, using other available products on the market and the selection of their mixtures.

This study investigated the potential of three microalgae taxonomic groups of Chlorophyta, Cyanoprokaryota and Bacillariophyceae for biogas production. Biogas potential was assessed in mesophilic anaerobic digestion batch tests over a period of 20 days. The cumulative biogas yield (CBY) of Chlorophyta and Cyanoprocaryota was respectively 396.21 mL/g Volatile Solids (VS) and 382.45 mL/g VS. Bacillariophyceae digestion showed lower biogas production of 357.07 mL/g VS. The highest cumulative methane yield (CMY) of 241.25 mL CH4/g VS was recorded for Cyanoprocaryota biomass, which was signifi cantly higher (p<0.05) than the other two types of microalgae. The highest methane content in biogas of 63.08% was observed with Cyanoprokaryota. Chemical composition of biomass as well as biogas productivity are infl uenced by algal taxonomy.

Opis:
The share of renewable energy, which is used for power supply, increases worldwide steadily to avoid the threat of climate change. In the renewable energy production from renewable resources biogas plays an important role. Biogas can be provided continuously by the permanent availability of biomass and it is also easily to store. In the context of competition for land between food and feed production as well as the cultivation of renewables an efficient biogas production is extremely important. Strategies for this aim are installing biogas plants in order to increase the biogas output and take measures to increase the efficiency of existing biogas plants or of concepts of biogas digesters for the new installation.

Ultrasonic disintegration is one of the most interesting technologies among all known and described technologies for sewage sludge pre-treatment before the process of methane fermentation. This study was aimed at determining the effects of an innovative ultrasonic string disintegrator used for sewage sludge pre-treatment on the effectiveness of methane fermentation process. In this experiment, we used a device for disintegration of organic substrates, including sewage sludge, with the use ultrasonic waves. Its technical solution is protected by a patent no. P. 391477 – Device for destruction of tissue and cell structures of organic substrate. The volume of biogas produced ranged from 0.194±0.089 dm3/g o.d.m. at loading of 5.0 g o.d.m./dm3 and power of 50 W to 0.315±0.087 dm3/g o.d.m. at loading of 4.0 g o.d.m./dm3 and ultrasounds power of 125 W. The study demonstrated a positive effect of sewage sludge sonication on the percentage content of methane in biogas. Sewage sludge exposure to 125 W ultrasounds increased methane content in biogas to 68.3±2.5 % at tank loading of 3.0 g o.d.m./dm3.

Opis:
One unconventional source of energy, which may be applied in numerous production and municipal processes, is energy accumulated in plants. As a result of photosyn-thesis, solar energy is transformed into chemical energy accumulated in a form of carbohydrates in the plant biomass, which becomes the material that is more and more sought by power distribution companies and individual users. Currently, a lot of re-search on obtaining biogas from energy crops is conducted. Corn silage is used most often, however, there is a demand for alternative plants. The experiment described in this article was conducted with the use of giant Miscanthus (Miscanthus Giganteus).

Opis:
One of the most commonly used substrates in biogas plants is maize silage, however, the application of monofermentation technology under Polish economic conditions has a tendency to rapidly bankrupt the investor. The lack of profitability of investments based on this material has encouraged investors to search for other, more economically favourable biomass sources i.e. maize straw. The aim of the research was to compare the energetic potential of untreated maize straw and extruded maize straw used for biogas production and furthermore, to determine the amount of electricity and heat generated as well as the amount of heat produced from direct combustion. The results obtained confirmed the substantial energy potential of maize straw. It has been proven that using the extrusion method as a pretreatment before the fermentation process, enables the producer to increase biogas and methane production respectively by 7.50 and 8.51%. However, the use of an extruder machine in biogas plants in Poland is economically unjustified due to its high energy consumption. Moreover, it has been shown, that the use of maize straw in the methane fermentation process enables it to generate (in Poland) a higher income than is the case of using this material in a direct combustion process.

Opis:
The pursuit of reduced greenhouse gas emissions, as well as the increased share of renewable fuels in the overall energy balance has led to a search for alternative energy sources. One of the fuels on which great hopes are set as fuel for engines is biomethane or biogas, whose main component is methane. Biogas can be obtained from different products by using different technologies, so that it has potential as a widelyavailable fuel, which is quite easy to produce. The percentage of methane in biogas depends on the technology for obtaining biogas and ranges from 35% to around 75%. The largest biogas sources can be animal farms, where it is obtained from animal excrement. Another source is sewage treatment plants and rubbish dumps, where substantial quantities of biogas are obtained as a result of natural processes occurring in waste dumping sites or sewage. Biogas can also be acquired from waste obtained from fruit and vegetable processing as well as waste from meat plants. This paper examines the possibility of using biogas as a fuel for diesel engines. In these engines, the combustion of biogas (methane) requires the application of a dual-fuel supply system in which liquid fuel initiating gas fuel selfignition will be injected into the combustion chamber along with methane. The paper also contains example results showing the effect of the methane dose on the course of the combustion process in diesel engines.

A pressing concern of issues such as climate change has drawn main attention in the world. The burning of fossil fuels by human due to increasing energy demand in various sectors is one of the main factors that influence the climate change. This has resulted in the introduction of many renewable energy sources as alternatives to fossil fuels. Biogas is one type of renewable energy that has numerous advantages. The present review covers the recent challenges of biogas production and its conversion to electrical energy. This includes the substrates used, the operating parameters, and the pre-treatment used, which can be implemented to maximise the biogas yield. The challenges and potential of the generation of electricity from biogas were also discussed in this review. The results obtained in this review emphasise that biogas is a good renewable energy, as it solves multiple problems and at the same brings benefits to human beings in many ways.

The so-called wastes that we discard and suffer with the consequences of improper management are of course partly huge energy and fertilizer sources that can support energy demands of cities greatly. Urban waste disposal is a serious challenge in all cities in the developing world, and its accumulation is an additional health hazard. Reliable and generally accepted disposal of the comparatively large amounts of digestate produced is necessary if biogas production is to be implemented. In this regard‟s discussion has been about the biogas production reaction involves, design and applications

W artykule przedstawiono wyniki badań dotyczące wydajności produkcji biogazu oraz metanu z sorgo cukrowego (Sorghum bicolor) odmiany ród J1052 o różnej długości sieczki. Materiał badawczy stanowiła kiszonka z sorgo o różnej długości sieczki (do 4 mm, do 10 mm, 25-30 mm) oraz gnojowica świńska. Badania laboratoryjne nad fermentacją metanową statyczną wykonano w trzech powtórzeniach, zgodnie z wytycznymi niemieckiej normy DIN 38 414 – S8. Fermentacja beztlenowa w warunkach laboratoryjnych trwała 58 dni dla każdej z prób w jednym powtórzeniu. Przebieg fermentacji metanowej kiszonki z sorgo o długości sieczki 25-30 mm wykazywał się większą stabilnością, w porównaniu z pozostałymi wariantami użytymi w doświadczeniu. Kiszonka z sorgo o długości sieczki 25-30 mm oraz do 10 mm z N (azot użyty do wyporu powietrza z butli fermentacyjnej) dały najwyższy uzysk biogazu (327,92 oraz 315,41 Ndm3·kg smo-1). Najniższą wydajność biogazu oraz metanu odnotowano w próbach z kiszonką z sorgo o długości sieczki do 4 mm. Kiszonka ta cechowała się relatywnie wysoką procentową zawartością metanu w biogazie (59% CH4).
The paper presents the research results concerning efficiency of biogas and methane production from sorghum bicolor of ród J1052 cultivar with different length of chaff. Silage from sorghum of a varied length of chaff (to 4 mm, to 10 mm, 25-30 mm) and pigs manure constituted a research material. Laboratory tests on static methane fermentation was carried out in three replicate tests, pursuant to the guidelines of the German standard DIN 38 414 – S8. Anaerobic digestion in laboratory conditions lasted 58 days for each test in one repeat. The course of methane digestion of sorghum silage of the chaff length 25-30 mm showed higher stability in comparison to the remaining variants used in the experiment. Sorghum silage of 25-30 mm chaff length and to 10 mm with N (nitrogen used for uplift pressure of air from digestion bottle) gave the highest biogas yield (327.92 and 315.41 Ndm3·kg smo-1). The lowest biogas and methane yield was reported in tests with sorghum silage of the chaff length up to 4 mm. This silage was characterized with relatively high percentage content of methane in biogas (59% CH4).

Opis:
Since anaerobic digestion (AD) is the preferred procedure for sludge treatment and disposal, it is constrained by the hydrolysis and acidogenesis stages. Nanomaterials have an impact on the AD process due to their unique properties (large specific surface areas, solubility, adsorption reduction of heavy metals, degradation of organic matter, reduction of hydrogen supplied and catalytic nature) which make them advantageous in many applications due to their effectiveness in improving the AD efficiency. Magnetic Nanoparticles (MNPs) were used in the present study to improve the biogas production. The experiments were divided into two stages to evaluate the effect of adding MNPs to two types of sewage sludge (SS): attached growth process (AG) and activated sludge (AS). The first stage consists of 15 tests divided into three experiments (A, B, and C). Doses of MNPs (20, 50, 100, 200) mg/l were added to all digesters in the same experiment except for one digester (the control). Experiments A, B and C achieved the highest biogas production when 100 mg/l of MNPs was added. They were 1.9, 1.93 and 2.07 times higher than the control for A, B and C respectively. The second stage consists of 12 tests with a pretreatment for some of SS. It was divided into two experiments (D, E), where the chemical pretreatment was applied to experiment D and the thermal pretreatment was applied to experiment E except for the control. For digester D4, which had 100 mg/l of MNPs after a chemical pretreatment at pH = 12, the biogas production increased by 2.2 times higher than the control (D0) and 1.5 times higher than the untreated sludge with the addition of 100 mg/l MNPs (DN). Thermal pretreatment at 100 °C with addition of 100 mg/l MNPs (E4) achieved a biogas yield 2 times higher than the control (E0), and 1.39 times higher than untreated sludge with 100 mg/l MNPs (EN). The previous results indicate that the integration of magnetite can serve as the conductive materials, promoting inherent indirect electron transfer (IET) and direct interspecies electron transfer (DIET) between methanogens and fermentative bacteria which lead to a more energy-efficient route for interspecies electron transfer and methane productivity. This study demonstrated the positive effect of magnetite on organic biodegradation, process stability and methane productivity.
