Methane is one of the greenhouse gases contributing to global warming. The capture of methane emissions in the waste sector is addressed by collecting it and using it for energy production. Methane emissions from active or closed landfills can be reduced by methane oxidation, which is developed as a covering over these landfills. It is usually composed of a gas distribution layer that favours micro-organisms that consume methane. The aim of this study is to find the most appropriate composition of the biocover in which filling material waste is used. In laboratory conditions, an experiment was conducted that studied the effectiveness of the biocover developed in the laboratory. Three experimental columns were created at a height of 160 mm and 1500 mm. A active compost saturated with water at a thickness of 500 mm was used as a source of methane, a permeable layer of sand at a thickness of 300 mm was further formed and finally covered with biocover. The biocover was composed of 60% of fine fraction waste, 20% soil and 20% compost, of the total volume. The experiment was created on 6 June 2022 and the first measurements were made two weeks later with CRDS equipment Picarro G2508. Measurements were made weekly for 4 months. The results of the study show that methane is released more forcefully after the first two months of application of the biocover. This is related to compost in the biocover, which has started to decompose actively, that methane oxidising micro-organisms develop on average after two months.","PeriodicalId":234250,"journal":{"name":"22nd SGEM International Multidisciplinary Scientific GeoConference Proceedings 2022, Energy and Clean Technologies, VOL 22, ISSUE 4.2","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132464439","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This is particularly true for shipping, including all its modes like long-distance, short-sea and inland shipping, where environmental regulations have become very strict in the last decade. On the one hand, fishing vessels are slightly out of these regulations, but on the other hand greening the fishing fleets is highly promoted by the European Union funding bodies as well as by the local authorities, while at the same time fishing vessels are rather aged with low energyefficient fossil fuel-based power systems. This paper illustrates aims, activities and current outcomes of a network of scientists and fishery cooperatives oriented to improve environmental friendliness of fishing vessels in the Adriatic Sea. In that process, an extensive fuel consumption measurement campaign involving 10 fishing vessels (9 purse seiners and 1 trawler) is being conducted and is offering an insight into emissions of these vessels and their relation to the operative profile and benefit for the society expressed in amounts and type of the caught fish.","PeriodicalId":234250,"journal":{"name":"22nd SGEM International Multidisciplinary Scientific GeoConference Proceedings 2022, Energy and Clean Technologies, VOL 22, ISSUE 4.2","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125345994","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As both alternative and green sources of energy, many may assume that wind energy is replacing fossil fuels such petroleum and natural gas and leading us to a more sustainable future. While renewable energy is part of the sustainability equation, another common attribute of achieving sustainability is the localization of production and consumption. In many ways, this almost automatically occurs with wind turbines because electricity does not transport well over long distances. However, despite this characteristic of electricity, it does not mean that electricity cannot be exported, especially when political geographies are considered. Indeed, this research will examine the U.S. state of South Dakota to demonstrate that wind-generated electricity can be treated from an economic point of view as an export commodity despite any local benefits that it generates. By examining statistics for electricity generation, it will be seen that wind energy is doing much more than replacing local electricity generation by fossil fuels. Further examination will show that a significant amount of wind-generated electricity in South Dakota is exported outside the state.","PeriodicalId":234250,"journal":{"name":"22nd SGEM International Multidisciplinary Scientific GeoConference Proceedings 2022, Energy and Clean Technologies, VOL 22, ISSUE 4.2","volume":"133 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121373426","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Biochars improvement for different usages is currently looked at. One of the ways to produce biochar is pyrolysis. The temperature and type of atmosphere in the furnace used play an important role on the quality of biochar produced. The current paper investigates the effect of temperature on the quality of biochar produced from raw palm nutshells through pyrolysis. The temperature was varied from 500-C to 900oC while the size of particles fed into the furnace ranged from 5mm to19mm. The quality of the raw palm nutshell and the biochar were assessed through characterization using proximate analysis and SEM-EDS to quantify the amount of fixed carbon and pores sizes corresponding to different sizes of the palm nutshell treated. The trends of fixed carbon and the change in temperature as well as the pores sizes were assessed in all the biochars produced and the correlation established. A tube furnace was used for the experiments with argon being blown to keep an inert atmosphere and avoid any destruction of carbon. A further correlation between the size of particles and fixed carbon was also assessed and a correlation established.","PeriodicalId":234250,"journal":{"name":"22nd SGEM International Multidisciplinary Scientific GeoConference Proceedings 2022, Energy and Clean Technologies, VOL 22, ISSUE 4.2","volume":"76 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127682954","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This article focuses on the effect the electric scooter use has on CO2 emissions by examining the electric scooter trip data obtained during 2021 scooter season in Riga city. As shared scooters routinely replace already existing modes of transportation, the article analyses the effect which this replacement has on net CO2 emissions in the city. We argue that not all replacement modes will bring actual decrease of CO2 emissions. The results indicate that most of the shared e-scooter trips in Riga fall into the 1-2 km distance category, where it replaces not just cars, but also public transportation, walking and cycling, and actually increases CO2 emissions. The article examines the factors contributing to the CO2 emissions and relative impact of each. The results demonstrate that the largest impact comes from the scooter and battery manufacturing, thus scooter lifetime has decisive impact on the overall net CO2 emissions. In addition, this research found fundamental differences between expected scooter lifetime data claimed by shared scooter operators (5 years) and the average reallife data (156 days). It results in shared e-scooters creating additional 239.9 tonnes CO2 in Riga, and minimum scooter lifetime should be at least 5 years, for shared scooters to become CO2 neutral. This study aims to contribute to transportation literature by demonstrating net CO2 emission calculation methodology as well as empirical evidence on e-scooter trips in North-Eastern Europe region and to help local authorities to make decisions on reaching environmental targets in transportation sector.","PeriodicalId":234250,"journal":{"name":"22nd SGEM International Multidisciplinary Scientific GeoConference Proceedings 2022, Energy and Clean Technologies, VOL 22, ISSUE 4.2","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114296550","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Several low-grade materials (zeolite, biochar) and building waste (concrete slurry waste) in original and surface modified forms were tested as selective adsorbents of As and Sb oxyanions from contaminated waters. The adsorption stability of oxyanions was verified by the Langmuir adsorption model. In natural systems As oxyanions demonstrated the preferential affinity for iron (Fe) oxides/hydroxides, while Sb oxyanions were more selectively binded to organic matter (OM).

Fertilizing fields with digestate provides many advantages, for example: reduced demand for plant protection products, reduction of unpleasant odor, and destruction of possible pathogens. The strengths and weaknesses of the implementation of biogas plants in Ukraine have been identified, and opportunities and threats have been considered. In general, the introduction of biogas technology is a very promising solution for the agricultural sector. Taking into account that a biogas plant is considered a potentially hazardous object for workers, it is necessary to constantly monitor the parameters of reactor operation in order to ensure the technological and environmental safety of the engineering facilities. For Ukraine, there is a shortage of specialists to set up an effective operation of biogas equipment and bring it to the industrial scale.

The potential of Brassica juncea seeds to germinate in a medium contaminated with high concentrations of Cu, Pb and Cd was assessed using germination tests on Indian mustard seeds in the presence of various liquid mixtures made from fertilizer and sterile material collected from three different mining sterile dumps in Maramures county, Romania. The experiment results showed that adding fertilizers did not enhance the germination process of Brassica juncea seeds and that the optimal pH for Brassica juncea to sprout extremely well is 5.5. The results suggest that Brassica juncea could be used in efficient phytoremediation of the sterile dumps.
