A one-way double nesting technique was applied, employing a mother domain with 15 km grid spacing and a nested domain with 3 km grid spacing. Twenty test simulations were performed with a model resolution of 15 km for the year 2000 on a Lambert Conformal Conic projection and 12 test simulations with a model resolution of 3 km for one monthJanuary 2000. Two planetary boundary layer schemes (UW PBL and Holtslag), four cumulus schemes (Emanuel, Grell, Tiedke and Kain-Fritsch), three explicit moisture schemes (Nogherotto-Tompkins, WSM5 and SUBEX) and two shallow convection configurations (MM5 and Tiedke) were tested. We used ERA-Interim reanalysis as boundary conditions for the 15 km runs with 0.75-degree horizontal resolution. The results are presented for several model output parameters (precipitation, temperature, surface pressure and cloud fraction cover). The output is compared with E-OBS observational dataset, satellite-based observations and ERA-Interim reanalysis. Based on the results, the model is sensitive to the choice of different parametrization schemes. The 15 km simulations overestimate the precipitation and underestimate the temperature in all scheme configurations. The biggest biases in precipitation and surface pressure we found in simulations with combinations with Nogherotto-Tompkins moisture scheme.

FAO defined food losses as losses along the food chain between producer and market, while safe and nutritious food is thrown away as waste. About a third of the food produced is wasted. A significant amount of food is disposed of as waste, especially in developed countries, and this also means the disposal of resources used to produce food. Food waste is not only an economic problem, but also an environmental and moral problem. Food diverted to landfills directly contributes to climate change by emitting methane (CH4), a significant greenhouse gas 25 times stronger than carbon dioxide (CO2) Even when all actions have been taken to use the waste food, some inedible parts will remain and can be turned into compost to feed and nourish the soil. A promising approach for improving soil services and crop productivity is the transformation of food by-products and waste into soil amendments. Industrial by-products of food processing and manufacturing represent 14% of the total food waste generated. These by-products of food processing present a significant opportunity to reuse the waste by transforming it into amendments for degraded soils.

In developing countries, it is necessary to improve the efficiency of biogas production to contribute to the decarbonization of the energy supply. This study aims to assess the quality of biogas produced from household biogas plants in rural areas of Cameroon. Through snowball sampling, data were collected from forty-five (45) functional biogas plants across the five agroecological zones of the country. Biogas was analyzed using the portable BIOGAS 5000 gas analyzer and compared for different designs of biogas plants and geographic locations. The results show on average that the floating drum biogas plant produced biogas with a higher methane content (57.90% v/v) than the floating drum design (55.30% v/v). The mean carbon dioxide content is 38.80% v/v for the fixed dome and 30.25% v/v for the floating drum biogas plant. Statistical tests indicate that the location of the biogas plant affected the methane content of the biogas produced. The feedstocks and design of biogas plants varied with the different agroecological zones of the country, and majorly accounted for the different qualities of biogas. The quality of biogas in Cameroon is within the reported range (average) of biogas quality in developing countries. However, it is still essential to promote the production of biogas with optimal quality in the country.","PeriodicalId":234250,"journal":{"name":"22nd SGEM International Multidisciplinary Scientific GeoConference Proceedings 2022, Energy and Clean Technologies, VOL 22, ISSUE 4.2","volume":"66 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":"124517186","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}

It is possible to reduce this pollution by constructing treatment wetlands, but these wetlands use significant amounts of natural aggregates. The question arises: is it not possible to replace non-renewable resources with recycled materials made from construction and demolition waste? This article examines the applicability of recycled building materials as filter media for vertical subsurface flow filters. The recycled aggregates of the 0-4 mm fraction are evaluated in terms of grain size and hydraulic conductivity. For the Czech Republic-s available raw recycled aggregates, washing methods are proposed to produce materials that meet the required grain size limits. Untreated aggregates contain a significant proportion of particles smaller than 0.063 mm (up to 21.8%), significantly reducing their hydraulic conductivity and preventing their use in water filtration. However, concrete and masonry aggregates with dust particle contents of 0.3% and 1.5% can be obtained through washing. The washed materials subsequently show an increase in hydraulic conductivity up to the required range of values, that is 10?4-10?3 m s?1. According to the evaluation carried out, it is possible to apply treated recycled materials to wastewater filtration. At the same time, the application of construction waste in constructed treatment wetlands creates opportunities to use fine recycled aggregates (0-4 mm) in these areas, which are currently limited, in the future.","PeriodicalId":234250,"journal":{"name":"22nd SGEM International Multidisciplinary Scientific GeoConference Proceedings 2022, Energy and Clean Technologies, VOL 22, ISSUE 4.2","volume":"17 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":"131380960","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}

One strategy to reduce the concentration of carbon dioxide in the atmosphere is to capture carbon dioxide from industrial emissions, since this is where the gas is found in high concentrations. In addition to physical and chemical methods, carbon dioxide capture is possible with the help of biological methods, for example, using microalgae. However, the optimal growth temperatures for microalgae are in the range of 20-30 degrees Celsius, and the emission temperature is much higher. In general, heat-resistant species can be distinguished, for example, from hot springs. But, as a rule, such species require specific growing conditions, which on an industrial scale will lead to an increase in the cost of equipment. The purpose of this work was to carry out adaptation to semi-high temperatures of microalgae species selected from local conditions. We conducted an experiment in which we compared the growth of three types of green microalgae isolates at room temperature and elevated temperature. The isolates were used in their initial state and after adaptation at gradually elevated temperatures. It was demonstrated that temperature adoption led to higher yield of the isolates when they were cultivated at 36 -C. Thus, for strain 2 the Dopt of the previously adapted variant 2e was 1.9-fold higher as compared with that of the initial variant 2i. For the other two strains such a difference was less, but still significant. The results obtained demonstrate the potential of the green algal species to be adopted to elevated temperature which is important for their future use in the biotechnologies of carbon capturing from the industrial emissions.","PeriodicalId":234250,"journal":{"name":"22nd SGEM International Multidisciplinary Scientific GeoConference Proceedings 2022, Energy and Clean Technologies, VOL 22, ISSUE 4.2","volume":"112 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":"132544612","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}

By the evaluation of the long-term data series, we can divide the PM10 concentration to its fractions PM10-2,5, PM2,5-1, PM1 and evaluate their behaviour. The aim of the work was to evaluate the data in order to recognize the resuspension process, even with a fine fraction, PM1. The data were then compared with the NOx values to determine if the PM originated from combustion processes. The original assumption of a correlation between NOx and PM1 was not confirmed in most cases. The results show that in some cases coarse PM are dominantly associated with NOx.
