In the quest to identify the optimal fluid for liquid desiccant systems, alternative desiccant solutions have been explored in terms of their feasibility and compatibility in dehumidification systems. This study proposes and characterises a new type of less expensive mixture of potassium formate (HCO2K) and 1-ethyl-3-methylimidazolium acetate ([EMIM][OAc]). This novel desiccant solution was investigated in terms of corrosiveness to metals, moisture absorption and desorption ability, cost-effectiveness compared to conventional desiccant solutions. The corrosiveness of desiccant solutions to copper-nickel, copper and steel was tested at room temperature and at 60 °C. Experiments were conducted in a climatic chamber with temperatures of 25–31 °C and relative humidities of 80–90% for the absorption process and temperatures of 50–70 °C and relative humidities of 20–30% for the desorption process to assess the moisture absorption and desorption capacities and mass fraction variations of the desiccant solutions. The mixed desiccant of HCO2K/[EMIM][OAc] in the ratio 60/10% wt. showed a moisture absorption capacity of 0.146 gH2O/gsol (compared to 0.18 gH2O/gsol for aqueous lithium chloride at 33.3% wt.) for a temperature and relative humidity of the climatic chamber of 25 °C and 90%, respectively. Its low corrosiveness, good moisture absorption and desorption capacity and higher cost-effectiveness make it a promising alternative to conventional desiccants, such as aqueous solutions of lithium chloride.","PeriodicalId":447585,"journal":{"name":"Green Energy and Sustainability","volume":"5 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141021830","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}

Wastewater treatment plants (WWTPs) have environmental burdens associated with energy consumption and sludge management. These burdens are linked, for instance, to energy consumption and sludge management. To diminish the environmental impact of the WWTPs, solutions like the developed one in the LIFE B2E4sustainable-WWTP project (B2E) arose. The B2E solution seeks to decrease some of the WWTP burdens by managing \u0000in situ the sludge generated in the WWTP through a gasification stage, valorising the syngas obtained in a cogeneration engine to produce both thermal and electrical energy. This reduces both the environmental impacts and costs derived from the sludge treatment by an external entity, being a self-sustainable solution in terms of energy. The B2E solution is designed for midsize WWTPs (10,000 and 100,000 PE), the majority of the European WWTPs.\u0000Methods: The Life Cycle Assessment (LCA) was selected to evaluate the environmental performance of the B2E system. Six impact categories were analysed under the environmental footprint methodology (EF 3.0): climate change, freshwater ecotoxicity, freshwater eutrophication, human toxicity (cancer and non-cancer) and resource use (fossils). \u0000To check if the B2E solution reduced the environmental burdens, \u0000a comparison with a baseline (BS) system, typically implemented in midsize WWTPs, was performed.\u0000Results: The B2E system showed an environmental improvement compared to the BS in the six studied impact categories. The largest difference was observed in both human toxicity (cancer and non-cancer) impact categories. Their impacts were 99% lower compared to the BS. The reduction of the environmental impact for the rest of the categories ranged between 19% and 48%.\u0000Conclusions: These results demonstrate from an environmental point of view that the B2E system has the potential to be implemented in midsize WWTPs in the near future. However, the technology should confirm these results under an operational environment to test the whole system by obtaining only representative primary data, which would enable future implementation strategies towards more efficient and sustainable WWTPs.","PeriodicalId":447585,"journal":{"name":"Green Energy and Sustainability","volume":"68 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129245006","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}

Three sets of experiments were carried out: In the first set, six experimental groups were tested; one autotrophic, one heterotrophic and four mixotrophic where cultivation modes carried out and biomass productivities were compared to each other. In the second and in the third set of experiments, the algae were exposed to four or five concentrations of cobalt (Co) or of molybdenum (Mo) respectively; in these sets of experiments the effect of Co and Mo on the biomass productivity and on the lipid content and distribution of M. gaditana was examined. In the 1st set of experiments, the mixotrophic cultivations, the initial carbon concentration, C(0), was equal to \u00002.87 g/L, 2.92 g/L, 3.96 g/L and 4.96 g/L and in the heterotrophic cultivation C(0) was equal to 2.24 g/L. Nitrogen initial concentration, Ν(0), was held constant at 77.1 mg/L. For the heterotrophic and the three mixotrophic cultivations, the biomass yield, when expressed as g/(per L-g of added carbon) was highest for the heterotrophic growth. In the 2nd and 3rd sets of experiments it was found that both Co and Mo affect biomass productivity and lipid distribution. Co, even at relatively medium concentrations, strongly inhibited the growth. On the other hand, Mo, even at relatively high concentrations, did not affect substantially the growth rate of M. gaditana. The lipid distribution showed that for most treatments with varying concentrations of Co and Mo, MUFA prevailed while, n-3 PUFA up to 26.6% and 19.4% of the total FA were obtained. Lipid and protein contents of the biomass for the treatments with Co were up to 8.18% and 14.97% respectively, while the respective values for the treatments with Mo were higher up to 16.67% and 17.76%.","PeriodicalId":447585,"journal":{"name":"Green Energy and Sustainability","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133500356","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}

The area is located in northern Greece and is a protected settlement. All the points where the measurements were made are paved with dark gray granite blocks. This material has always been used to pave the open public spaces of the old town. Through the comparison of temperature measurements, it was found that the older paving materials develop higher temperatures compared to similar, but newer materials. Thus, it was concluded that the age of the paving materials affects the comfort of the users of the open public spaces. To test this, measurements were made during two months in spring and summer. During this period, the temperatures are higher and thus affect the users of the outdoor areas more; this results in a more useful comparison of the coating materials.","PeriodicalId":447585,"journal":{"name":"Green Energy and Sustainability","volume":"8 4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123688880","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}

Our analysis suggests that the biomass fraction of municipal solid waste, the biomass fraction of industrial waste, animal manure and sewage sludge, tree prunings, carbon dioxide feedstocks from industrial sources and refuse derived fuels/plastics are feedstocks with sufficient availability until 2050 for the production of renewable fuels and gases for the transport sector in Greece. As a rough indicator, if all the technically achievable feedstocks covered in this study are converted into associated advanced fuels (excluding recycled carbon fuels), this could equate to 7% in 2020, 8.2% in 2030, 9.3% in 2040 and 10.3% in 2050 of the total energy consumed in the transport sector.
