Opis:
Renewable energy sources have been amongst crucial elements of the European Union policy for a long time. Currently, they have become significant in terms of possibilities of the technology development, which may limit the effects and duration of the economic, energy and climatic crisis. The Directive 2009/28/EC obliges the increase of the share of Renewable Energy Sources in the final energy consumption up to 20% (in Poland up to 15%) by 2020. Sewage sludge is waste that significantly affects the aspects of environment. The research considered the rationality of using the waste for the production of biomethane. The purpose of the work was to determine the dynamics of biogas production from sewage sludge of municipal origin. Its scope included a review of the literature based on the Polish and European law. Issues of technology, production and use of biogas and residue were presented. The research was based on determining the properties of sewage sludge - raw and after stabilization, and carrying out a fermentation process for a period of 30 days. The validity of using sewage sludge as substrate for biogas production was confirmed.

Opis:
A distinguishing feature of the sustainable bioeconomy is multi-product biomass processing in the form of a closed circulation of matter and energy, in addition to a life cycle assessment that includes end-of-life options of a product and restitution of the environment. This approach is in-line with the good practice principles of sustainable development. However, the market of bio-based products grows faster than its legal regulation. Gaps in the regulations pertaining to standardisation, certification and labelling mean that bio-based products and their processing technologies may not adhere to the guidelines of sustainable development (“greenwashing”). In the European Union, the only standard addressing criteria of sustainable development with respect to bio-based products is the standard CEN-TC411 EN 16751:2016. In the context of anaerobic fermentation and its products as an option of the end-of-life phase of a bio-base product, the applicable regulations are contained in the technical report CEN-TC411 TR 16957:2016, Waste Framework Directive 2008/98/EC, and several intermediate regulations concerning the utilisation of water, energy efficiency, agricultural production and processing, circulation of nitrogen in the environment, storage and disposal, and others.

Opis:
This study evaluated the biogas production potential of water lettuce (Pistia stratiotes L.) by batch anaerobic digestion under in-vitro conditions. Twenty-one litre-plastic jars were used to conduct 4 replications over 75 days. The results showed that solution temperature, pH and Eh were suitable for biogas production. More than 50% of the obtained CH4 was formed within 17–42 days after incubation. The maximum daily CH4 production was 0.052 L/gVS, whilst the daily H2S concentration was low, with a maximum value of 28 ppm within 14–21 d after incubation. Moreover, the peak of daily biogas production was seen at day 16 with production of 0.12 L/gVS. The results highlight that water lettuce biomass can be potentially used to produce high quality biogas in anaerobic incubation.

Opis:
The main objective of this study was to analyse the development of dry anaerobic digestion process of OFMSW in batch reactors under two temperature ranges, thermophilic (55°C) and mesophilic (35°C). The experimental results lead to the conclusion that the thermophilic range has a greater rate of hydrolysis and is therefore more effective to degrade wastes, shortening the overall operating time. For example, the hydrolytic step in the thermophilic (T) process lasted an average of 8 days versus 14 days in the mesophilic (M) range. The methanogenic phase lasted for 18 and 29 days in the T and M processes, respectively. The mesophilic range showed higher removal of the organic effluent but with greater uptime requirements. Moreover, the thermophilic range showed greater productivities than the mesophilic range, and the productivities were approximately doubled in terms of the produced biogas from a given amount of consumed organic matter.

Opis:
Sawdust, as an agricultural waste which is highly efficient, readily available, and relatively inexpensive, has the potential to be an applicable alternative adsorbent for the total organic carbon (TOC) removal from synthetic domestic wastewater. This study aims firstly to investigate the feasibility of sawdust as a new adsorbent and understand its adsorption mechanism for TOC. The impact of particle size, pH, contact time, and temperature has been evaluated as the controlling factors on the adsorption process. The results presented that the removal efficiency rose with the decrease of particle size, pH, and temperature, as well as the increase of the contact time. The maximum adsorption was obtained at particle size of 0.05 mm, pH of 1, contact time of 1.5 h, and temperature of 15°C, respectively. The second aim of this study is to utilize the sawdust that is used in the adsorption process as biomass in batch anaerobic digestion (AD) to produce methane. Spent sawdust was characterized by the methane production which was 5.9 times greater than in the case of raw sawdust. Four operating parameters were checked, Carbon/Nitrogen ratio (C/N), inoculation, particle size, and total solid (TS) content. The batch results indicated that the optimum parameters were: 20%, 30%, 2 mm, and 15%, respectively.

Opis:
Digestate from a biogas plant can be a valuable organic and mineral fertilizer. Quantitative proportions of cosubstrates used in three agricultural biogas plants in Poland were analyzed. The composition of digestates was examined and large differences in the content of macronutrients were found, especially N and K. On the basis of the factors used to calculate emissions from the production and use of artificial fertilizers, the greenhouse gas (GHG) reduction resulting from replacing mineral fertilizers with digestate was calculated. In terms of 1 Mg of fresh digestate, this reduction may not seem large, as it amounts to 27.9–61.6 kg of CO2 eq, but it should be taken into account that digestate contains little dry matter. The annual amount of digestate used on an area of 1 ha allows avoiding GHG emissions of 25.8–44.5 Mg CO2 eq.

Opis:
Anaerobic digestion is the biological degradation of biomass in oxygen-free environments. The main product of this process is biogas, rich in CH4 and CO2. Understanding the heat loss characteristic of biogas digester (BD) is important to put these technologies into application. Biogas digester may obtain assumed gas production in cold environmental when the optimal fermentation temperature is maintained. It requires heating system and insulation technologies. Here 2-D axisymmetric steady heat transfer model coupled with surrounding soil was built to calculate heat loss of HBD for a real biogas plant located in north-eastern Poland. A sample to determine the effect of air flow between the membranes of the BD cover on the heat losses has been presented.

Opis:
In recent years, it is observed an increase in the use of natural fertilizers that are environmentally friendly. The effluent after microalgae anaerobic digestion (algal effluent) contained organic substances and mineral compounds necessary for lettuce cultivation, hence it is a competitive product for natural fertilizers and an alternative to mineral fertilizers. The experiment was conducted under laboratory conditions. The main objective of the research was to assess the possibility of using the algal effluent as an organic fertilizer for the cultivation of butterhead lettuce. The study also analyzed the effect of the algal effluent on physicochemical properties of soil and plant growth. The experiment was established on podzolic, light soil of VI fertility class, under granulometric composition of loose sand. Plants used in the experiments are butterhead lettuce, variety 'Attractie'. The experiment was conducted in three replicates. Doses of fertilizers have been established due to factors: the content of nitrogen as the main macro element determining the growth and development of plants, nutritional requirements of tested plants and current soil fertility. The performed complex soil analysis and pot experiment showed that the algal effluent can be successfully used to improve soil fertility and enhance plants growth. Addition of the algal effluent caused increase of total organic carbon by 2066 mg/kg, total phosphorus by 27 mg/kg, total potassium by 55 mg/kg, total magnesium by 57 mg/kg, total calcium by 183 mg/kg. C/N ratio has increased from 9.1 to 11.2. pH maintained at the same level.
W ostatnich latach obserwuje się wzrost stosowania nawozów pochodzenia naturalnego, które są przyjazne dla środowiska naturalnego. Użyty w badaniach odciek pofermentacyjny po beztlenowej fermentacji glonów zawierał substancje organiczne i związki mineralne niezbędne do uprawy sałaty. Dzięki ww. składowi odciek może stanowić konkurencyjny produkt dla nawozów naturalnych i alternatywę dla nawozów mineralnych. Badania prowadzono w warunkach laboratoryjnych. Głównym celem badań była ocena możliwości wykorzystania odcieku pofermentacyjnego z glonów jako nawozu organicznego pod uprawę sałaty masłowej. W pracy przeanalizowano również wpływ ww. odcieku pofermentacyjnego na właściwości fizykochemiczne gleby i wzrost roślin. Eksperyment założono na glebie bielicowej, lekkiej, klasy VI, o składzie granulometrycznym luźnego piasku. Roślinami użytymi w doświadczeniu była sałata masłowa, odmiana "Attractie". Doświadczenie przeprowadzono w trzech powtórzeniach. Dawki nawozów ustalono ze względu na następujące czynniki: zawartość azotu jako głównego makroelementu determinującego wzrost i rozwój roślin oraz wymagania pokarmowe badanych roślin i aktualną żyzność gleby. Przeprowadzona kompleksowa analiza gleby i eksperyment doniczkowy wykazały, że pofermentacyjny odciek z glonów można z powodzeniem stosować w celu poprawy żyzności gleby i zwiększenia wzrostu roślin. Dodatek pofermentacyjnego odcieku glonów spowodował wzrost całkowitego węgla organicznego o 2066 mg/kg, fosforu całkowitego o 27 mg/kg, całkowitego potasu o 55 mg/kg, całkowitego magnezu o 57 mg/kg, całkowitego wapnia o 183 mg/kg. Wskaźnik C/N wzrósł z 9,1 do 11,2. Wartość pH pozostała niezmieniona.

Opis:
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.

This study examined the effectiveness of thermophilic co-digestion of sewage sludge and milled/non-milled brewery spent grain. The experiments were performed in batch-mode to evaluate both the biogas potential and the biogas production rate. Five runs were carried out, one of them concerned the anaerobic digestion of sewage sludge (as control), whereas the others referred to the co-digestion of sewage sludge with addition of milled and nonmilled brewery spent grain at doses of 5 and 10 g. The runs were conducted under thermophilic conditions (temperature 55±1°C) and lasted for 21 days. The effectiveness of the process was assessed on the basis of the volatile solids removal, biogas potential and the rate of biogas production. The physiochemical composition of reactor feed and digestate were characterized. The addition of the brewery spent grain resulted in increase of the biogas potential, but a decrease in the volatile solids removal. In the case of biogas production rate, the highest value was recorded in the run with the addition of 10 g of milled and non-milled brewery spent grain (0.69 Ndm3dm-3d-1). There was no observed influence of milling on the thermophilic co-digestion effectiveness since the parameters specified revealed comparable values.

Methanogenic fermentation is promising method of obtaining environment-friendly energy. Moreover it can be used for disposal of sewage and other organic waste. However process complexity and susceptibility makes it difficult for application on a large scale. A new laboratory stand for studding of anaerobic digestion was developed. Three fermentation vessels and automated control system provides flexibility essential in investigation of digestion of different substrates and testing of different reactors configurations. Cheese whey is a troublesome dairy waste, potentially suitable for biogas production. Stable fermentation conditions for whey fermentation were obtained with the organic loading rate of 5 kg COD/m3 and methane production efficiency of 0,3 m3/kg COD. On the basis of obtained data the size of small biogas plant for average dairy was calculated.

Opis:
In 2016, in EU Member States (EU), only less than half of the biowaste produced, i.e. around 40 million tonnes, was used to produce compost and, to some extent, biogas. Most of it was still incinerated or stored together with other waste. On 14 June 2018, amendments to 6 directives on waste management were published. One of the most important changes introduced in the Waste Framework Directive is the obligation for Member States to recycle biowaste at source or selectively collect it for composting or fermentation by 31 December 2023 at the latest. The article presents the potential of biowaste and its use for the production of compost and changes in directives concerning the handling of biowaste, which will shape the directions of development of this waste management in the EU after 2020. The composting and fermentation processes of biowaste were also compared, defining their advantages and disadvantages. This information can be helpful in the selection of technologies for its processing, making decisions on the construction of new or modernization of existing installations.
W 2016 roku, w państwach członkowskich Unii Europejskiej (UE) tylko mniej niż połowa wytwarzanych bioodpadów, około 40 milionów ton, była wykorzystywana do produkcji kompostu i do pewnego stopnia biogazu. Większa część nadal była spalana lub składana razem z innymi odpadami. Jedną z najwazniejszych zmian wprowadzonych w dyrektywie ramowej w sprawie odpadów jest zobowiązanie państw członkowskich, aby do najpóźniej od dnia 31 grudnia 2023 r. bioodpady były poddawane recyklingowi u źródła lub selektywnie zbierane, w celu kompostowania lub fermentacji. W artykule przedstawiono potencjał bioodpadów i ich wykorzystanie do produkcji kompostu oraz zmiany w dyrektywach dotyczące postępowania z bioodpadami, które kształtować będą kierunki rozwoju gospodarki tymi odpadami w UE po 2020 r. Porównano również procesy kompostowania i fermentacji bioodpadów, określając ich wady i zalety. Informacje te mogą być pomocne przy wyborze technologii ich przetwarzania, podejmując decyzje o budowie nowych modernizacji istniejących instalacji.

The aim of the study was to elucidate the substantial relationship between the compositions of methanogen community that assembles in the anaerobic digester mass and link it to methane production activity. The results of the metagenomic studies were used to evaluate how the methanogen structure changes during an anaerobic digestion process under various waste retention times (21, 23, 25, 29, 33, 39, 47 and 61 days). Phylogenetically coherent populations of methanogens were assessed by 16S rRNA gene next-generation sequencing and terminal restriction fragment length polymorphism fingerprinting of a specific molecular marker, the mcrA gene. The results indicated multiple phylogenetically diverse methanogen populations associated with the various steps of anaerobic digestion. The stages of the anaerobic digestion process and waste retention times determine the microbial composition. The most dominant and acclimated microbial communities in all samples belonged to the genera Methanosaeta and Methanobacterium. The methane yield was consistent with the results of the microbial community structure, which indicated that acetotrophic Methanosaeta was the most active and most important during the methanogenic stage.
