It resulted in an increase in the number of infected patients. To overcome the problems, he government recommends that medical personnel to wear Personal Protective Equipment (PPE) to avoid direct contact between medical personnel and patients. As the number of Covid-19 transmissions increased, so did the number of medical wastes. One type of medical waste, disposable medical gloves are made of polymers and could not be broken down naturally by microorganisms in the environment. As a result, during this pandemic, disposable medical glove waste is significantly polluting the environment. Environmental issues can be overcome by properly handling of medical glove waste, such as by converting waste to energy (WTE) through the pyrolysis process. The design of pyrolysis equipment has become an important factor in converting waste into energy. The aim of this research is to determine a simple and easy-to-manufacture pyrolysis equipment design for converting medical gloves waste into an alternative fuel. According to the design, the pyrolysis vessel was made of stainless steel and had a maximum capacity of 3 kg/process. The tubing connector was made of stainless steel 304 (SS-304) and had a diameter of 2 cm. To maximize the condensation process, two condensers of stainless steel 201 (SS-201) were designed and built in series. The pyrolysis equipment has passed functional testing because the functional testing step revealed that medical gloves can be decomposed into fuel oil. © 2023 Author(s).","PeriodicalId":271964,"journal":{"name":"6TH INTERNATIONAL CONFERENCE ON CIVIL ENGINEERING FOR SUSTAINABLE DEVELOPMENT (ICCESD 2022)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128971611","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}

{"title":"Hatirjheel water-taxi service improvements considering riders pre-and-post-trip mode choice characteristics","authors":"Md. Shoaib Chowdhury, Md. Owalid Hossain","doi":"10.1063/5.0130354","DOIUrl":"https://doi.org/10.1063/5.0130354","url":null,"abstract":"Dhaka, the capital of Bangladesh, is one of the most congested megacities in the world today. It's predominantly road-based transportation systems have been failing to meet the dwellers mobility needs. Furthermore, the road congestion results in a significant GDP loss every year. The government has been undertaken (and continuing to undertake) numerous transportation systems and services improvement projects such as Metro Rail, BRT, flyovers and U-loop projects along major corridors. Furthermore, being a sustainable (environmentally friendly) mode, a Water-Taxi (WT) service was introduced in the Hatirjheel lake in December 2016 that currently serves major residential, educational, and business/commercial destinations including Rampura/Badda, Badda-Gulshan-1 link road, and Tejgoan/Kawran-Bazar areas through multiple routes. Previous studies reported that the demand for HatirJheel WT service outperforms its service capacity despite noted service weaknesses. This study assesses the WT service characteristics [i.e., WT station characteristics including their surrounding areas and adjacent bus stops, frequency/headway, travel (waiting and running) time, vessel capacity and ridership level as well as access (pre-trip) and egress (post-trip) modes of the riders]. Field data were collected and questionnaire-based surveys were conducted in late 2019 and early 2020 (just before the COVID-19 lockdown). The survey data reveals that a large percentage of WT riders are exchange (transfer) passengers from buses and para-transits. It is also found that WT operates on irregular headways causing long waiting times for riders. The physical separation between bus stops and WT stations, accessing issues (i.e., walking time and safe crossing of roads) with the WT stations as well as long waiting time at stations significantly deteriorate the WT service performance. Taking into consideration of the existing issues and challenges that may jeopardize the implementation of the proposed improvements, a SWOT analysis is also performed. This study recommends that schedule based reliable WT service with a desirable frequency and posted time-table should be introduced to minimize the waiting times at stations. The future study should focus on developing a model for analyzing the effectiveness of WT and bus system integration (i.e., physical and service - schedule and fare - integration between buses and WTs). If desired, WT and bus system integration would improve the service performance of both modes while attracting additional riders and ultimately supporting sustainable development (i.e., alleviating congestion on local roadways and improving air quality etc.). © 2023 Author(s).","PeriodicalId":271964,"journal":{"name":"6TH INTERNATIONAL CONFERENCE ON CIVIL ENGINEERING FOR SUSTAINABLE DEVELOPMENT (ICCESD 2022)","volume":"108 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125065797","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}

{"title":"Effect of Covid-19 lockdown on traffic and the crash rate of national highway: Evidence from Bangladesh","authors":"Md. Amirul Islam, Fahmida Hanif, Sumaiya Afrose Suma, M. A. Raihan, M. Hadiuzzaman","doi":"10.1063/5.0130111","DOIUrl":"https://doi.org/10.1063/5.0130111","url":null,"abstract":"This study aims to evaluate the impacts of the COVID-19 lockdown on traffic volume of national highways connecting Dhaka with other divisional cities considering pre, during and post-lockdown periods during COVID-19. Bangladesh Government imposed countrywide lockdown at different steps in different timeline, based on the dissemination rate of COVID-19 virus. As a part of controlling measures, the first lockdown was imposed on March 2020 and vehicular movement on highways connecting capital Dhaka with other divisional cities got banned. Thus, the vehicular traffic contributing to Dhaka using different highways got lessened over period. Before imposing every movement ban, people migrated and left cities. Considering all these scenarios, traffic volume has been studied for the eight National Highways (N1-N8). Along with this, the change in road crash rate over these periods has also been studied. Although it seems that, with the reduction of vehicular movements on road the crash rate would also be lessened, but the observed scenario is opposite. For example, on N1 from March 9 to March 25, 2019, the crash number was 3 and the fatality rate was 4, however in 2020, the numbers were 4 and 18. Moreover, the crash number on N5 was 6 during the shutdown period from March 26 to May 29, 2020, and it was 5 in 2019. The fatality rates were the same in both times, indicating that the travel restrictions did not reduce the number of crashes. The main causes of these collisions during the lockdown were mostly irresponsible driving and high speeds due to comparatively low traffic volume. On the other hand, the crash number on N7 was 17 after shutdown from 30 May 2020 to 28 November 2020, and it was 15 in 2019. It appears that, because passenger vehicle movement was restricted for a long period, vehicular mobility was exegeted, resulting in a rise in ADT values on national highways, as well as an increase in crash counts. Each year, many unexpected crashes occur on these national highways due to uncontrolled driving, overtaking, and high speeds. The study findings can help policy makers to understand the factors behind roadway crashes on the highways during the COVID-19 period. It would eventually govern reliable, efficient roadway system ensuring mobility with safety. © 2023 Author(s).","PeriodicalId":271964,"journal":{"name":"6TH INTERNATIONAL CONFERENCE ON CIVIL ENGINEERING FOR SUSTAINABLE DEVELOPMENT (ICCESD 2022)","volume":"86 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134155613","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}
