The natural occurrence of the raw materials and the idea to move closer to nature with its natural products have brought high interest in hempcrete. Hempcrete is a kind of binder-aggregate material where besides mineral binder, hemp shive aggregate act as a filler. A good technical performance of such composites has been reported before, while the term an ‘advanced material’ for traditional hempcrete lacks some superior properties for civil engineers. This research offers advanced hempcrete-type material where gypsum binder and hemp shives are used as the main components. Additionally, phase change material (PCM) was incorporated into the mixture composition to increase their thermal mass. PCM gives additional thermal heat storage for buildings which makes the building envelope more homogenous regarding thermal stability under outer temperature fluctuations. This could give additional comfort during heating and cooling seasons. Up to 20 wt.% of microencapsulated PCM suspension had been added to the hempcrete mixture composition and heat capacity was calculated and validated with differential scanning calorimetry measurements. Physical and mechanical performance was also evaluated. Results indicate that in the temperature interval from 20 to 30 °C, the heat capacity of hempcrete can be increased to 1901 J/(gK) (by 70.4 %) and it correlates well with theoretical thermal mass calculation. This gives promising results for further development of the material and proves the feasibility of PCM integration in hempcrete.","PeriodicalId":46053,"journal":{"name":"Environmental and Climate Technologies","volume":null,"pages":null},"PeriodicalIF":1.4,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72479084","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":null,"pages":null},"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}

Multifaceted studies by a wide range of scientists on the possibilities of the acoustic effect in fire extinguishing are noted. The analysis of literary sources showed the negative impact of both the fires themselves and the majority of fire extinguishing agents on the environment. Variants of the use of the acoustic effect for the prevention and elimination of fires of various combustible substances are considered. The influence of the frequency of acoustic waves, scanning speed, power, and other acoustic parameters on flame extinguishing is noted. The possibilities of using a deep neural network for flame detection have been studied. The limitations and advantages of acoustic technology and further prospects for its development as an element of environmental technologies are shown.","PeriodicalId":46053,"journal":{"name":"Environmental and Climate Technologies","volume":null,"pages":null},"PeriodicalIF":1.4,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88734538","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":null,"pages":null},"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}

The course ‘Energy transition and climate change’ covers one of the United Nations’ ‘Sustainable development goals’ and is one of twelve MOOCs that will enable a comprehensive education in system thinking and its applications. It shows how system thinking methods and tools can be applied to tackle current and future energy and climate problems. The goal of the MOOC is to introduce users to the internal dynamics of modern energy systems and energy transition toward CO2-neutral energy systems. The target audience of the course is students who study Environmental Engineering, Energy, Systems, or similar program and anyone else interested in insights into the topic. The course builds on previous energy supply and demand models by updating and adapting them to the existing situation. MOOC is designed by the Competency-Based Education (CBE) approach, and a literature review is used in the study to cover theoretical parts of the course. Technology Readiness Level (TRL) methodology describes the main steps of the course model development progress, and testing of MOOCs pilot version on five students is included in the final stage of the study.","PeriodicalId":46053,"journal":{"name":"Environmental and Climate Technologies","volume":null,"pages":null},"PeriodicalIF":1.4,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84983706","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}
