One of the best ways to improve the vehicle efficiency and its smooth ride is to make some rational changes in the vehicle design, one of which is to convert the mechanical energy accumulated in the vehicle’s suspension into electricity. The shock absorber in the suspension has been replaced with two different-type new recuperative devices, which replace the shock absorber and convert into electricity the loads coming from the road irregularities to pavement.","PeriodicalId":46053,"journal":{"name":"Environmental and Climate Technologies","volume":"13 1","pages":"213 - 227"},"PeriodicalIF":1.4,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73060133","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 consumption of paper and, subsequently, recycling are increasingly growing, contributing to vast quantities of paper sludge. Therefore, in waste disposal and environmental remediation, coping with massive volumes of paper sludge has received tremendous attention worldwide. Our purpose was to assess leading study advancements globally of paper sludge based on articles published, authors intra/inter-collaborations and accumulations of keywords. Throughout entire 1967–2019 duration, 2096 publications in paper sludge topic were mined using Scopus database. The findings revealed that the number of publications was less than 30 between 1967 and 1995, less than 60 between 1996 and 2005, less than 90 between 2006 and 2010 and more than 90 between 2011 and the recent year. Consequently, the yearly publishing is forecast to keep to expand. In a total of 125 journals, a total of 217 Canadian scholars from 155 universities lead to 263 papers, comprising 10.8 % total publications, where 261 (99.2 %) of 263 total English-language publications dominate the other countries/territories, while 0.8 % in French language. Also, from each of the 15 top countries, among the most productive universities, Université Laval was ranked 251st in World University Rankings 2021. In review, the following present developments in paper sludge comprise of: (i) cement, cellulose, bioethanol/biogas and concrete; (ii) phytoremediation and vermicompost and (iii) modelling (e.g., response surface methodology).","PeriodicalId":46053,"journal":{"name":"Environmental and Climate Technologies","volume":"59 1","pages":"256 - 275"},"PeriodicalIF":1.4,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82790650","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}

Its solution requires a multi-pronged effort and the use of diversified strategies. Since the impacts are on an environmental, social and economic level, solutions can take shape in one of these areas, knowing that there are often trade-offs between one and the other. This paper aims to evaluate the net environmental effects in terms of Carbon footprint of the activities of the Lithuanian Food Bank (Maisto Bankas). Food banks are charities that work to reduce the negative social effects associated with food waste and food insecurity. They work on the food recovery, avoiding the transformation of food surplus in food waste. The present paper assessed the positive impact generated by the Lithuanian Food Bank thanks to its activities as the non-impact of recovered food and the non-disposal of food in landfills. At the same time, also the negative impact in term of emission due to the management of all its activities has been estimated. The net impact has been derived by the comparison of the two flows. The results of the study proved that, behind the social benefit, the Food Banks, as Maisto Bankas, produce also a net positive environmental impact.","PeriodicalId":46053,"journal":{"name":"Environmental and Climate Technologies","volume":"70 1","pages":"240 - 255"},"PeriodicalIF":1.4,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91211360","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}

Using such systems, different advantage such as minimization of power loss, operating cost, and emission can be achieved. In this paper, the 24-hour power and heat based MG scheduling is investigated under environmental aspects and economic issues as bi-objective modelling in the presence of demand response (DR) program for decreasing greenhouse gas emission and system operation cost. The investigation of the MG contains energy storage system, boiler and combined heat and power (CHP). For solving the problem, first the Pareto optimal solutions have been obtained by the weighted-sum technique, then the fuzzy satisfying approach has been used to get optimal trade-off result. To confirm the performance of the method, the problem is solved in two-case to demonstrate the effects of DR on MG scheduling.","PeriodicalId":46053,"journal":{"name":"Environmental and Climate Technologies","volume":"34 1","pages":"730 - 741"},"PeriodicalIF":1.4,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77701465","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}

Given this sector’s importance, it is surprising that the external costs of transport are often measured only from the air pollution perspective, mainly CO2 emissions and the health effects associated with these emissions. However, other external costs should be considered when calculating the impact of transport. In this paper, external costs dependent on the type of motor and energy used in vehicles are calculated for Latvia’s current passenger car and light commercial vehicle situation. These external costs are compared with different proportions of battery electric vehicles (BEVs) in Latvia’s passenger and light commercial vehicle fleet. In addition, changes in employment associated with changes in the automotive sector are calculated. The results indicate that having a higher BEV proportion in the fleet reduces external costs in almost all sectors and increases job positions available in the automotive sector.","PeriodicalId":46053,"journal":{"name":"Environmental and Climate Technologies","volume":"134 1","pages":"1145 - 1157"},"PeriodicalIF":1.4,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76274020","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}
