The Construction and Demolition (C&D) industry is very close to various waste management issues as the generation of waste is inevitable in every construction. In Indonesia, to make an applicable implementation of C&D Waste Management, the improvement must be made by looking into the actual field process. The improvement uses DMAIC as the lean tools and VSM to state the current process of material from its delivery on the site into a waste. Waste that is being monitored is the most used materials in the case study project which are concrete. A notable project was taken for the study as it will help other structure projects to imitate the down-to-earth future state, aiming at the reduction of waste generation rate and also business process improvement. The result shows that the process of concrete from orders to waste took eight steps, and three of them are improved, producing 3% lesser waste from the current state. The best scenario WGR were analyzed to also answer the stakeholder interest within the case study.

Waste management in hotels has a significant role in reducing the negative impact on the economy and environment. The goal of this study was to discover hotel sector waste (HSW) by quantitative analysis of HSW in different size of hotels. The SPSS software was employed to predict the average HSW generation rate using nationality, type of waste, season, accommodation type, and type of waste management practices as predictors. The results showed that during lean season 2063.4 kg and high season 4160 kg. In the sampled accommodation, also during the lean season, the large hotels waste generation rate was (66.7%), medium hotels (19.4%), and small hotels (13.9%) and in high season HSW generation increase around (45%). From the total amount of waste generated in the sampled accommodation, 36% generated by the kitchen, and in other section, 7% of waste was glass, 8% nylon 4% plastic, 3%bottle, and 5% of wood. Also, 14% of the waste generated was recyclable waste in the sample accommodations. Besides, the result showed that the waste management practice rate in the small hotel is less than another accommodation sample size.

Medical Wastes

The management of medical waste (MW) is of great importance due to its impact on human health and environment. The present practices of improper management of generated medical wastes in different Healthcare Establishment (HCEs) in Rajshahi City Corporation (RCC) is playing a contributing role to create vulnerable condition in spreading out the Diarrhea, Hepatitis and various skin related diseases. The objectives of the study are to identify different types of wastes, its generation rate and assess the existing waste management in various HCEs. The study was carried out in 14 different HCEs that generated much portion of MW of total generated MW in RCC. The methodology of this project was descriptive and consisted of the use of field survey and interviews with the relevant authorities and personnel involved in the management of MW. It was found that the surveyed HCEs generate a total of 1495 kg/day of MW; of which about 1328.6 kg/day (88.87%) are non-infectious and about 166.4 kg/day (11.13%) are infectious. The average waste generation rate for surveyed HCEs is 1.54 kg/bed/day or 0.30 kg/patient/day. It was found from the survey that there is no proper and systematic management of medical wastes. The study reveals that lack of awareness; financial support and willingness are responsible for improper management of MW. So the RCC and HCEs authorities should adopt appropriate policy regarding this issue and provide training program on relevant personnel who are engaged in medical waste management.DOI: http://dx.doi.org/10.3329/jesnr.v6i1.22062 J.

Solid waste management in any large urban city like Lahore requires special disposal measures. In thisregard, Lakhodair landfill and Mehmood booti dump sites collect and handle major bulk of all the solid waste comingfrom ten towns of Lahore, with the city’s waste generation rate of being 0.84kg/capita per day. Spatial expanse of boththe sites was calculated in Arc GIS 10.3 system. The findings clearly showed that the extent of both these dump siteshad increased during 2006-2016 due to an enormous rise in solid waste generation. During 2006, the area of MehmoodBooti dump site and Lakhodair Landfill site was only 15 hectares and 17 hectares respectively. By 2016, this area hadincreased to 32 hectares and 52 hectares respectively. The mapping of these two sites can help in future researchesbased on investigating the disease patterns among people residing around these sites and by determining methaneemissions in the study area.

This article outlines the problem of waste accumulation as well as the associated environmental consequences in Ukraine due to the disparities between waste generation and utilization capacities. The analysis of quantitative parameters of waste generation sources and the territorial structure of Ukraine’s utilization capacities was carried out, and the spatial assessment of waste management system balance within regions was made. The work also identifies stages of territorially balanced management systems formation within the scope of current recycling technologies in the regional dimension. Methodological approaches to researching the balance conditions of waste management systems at the regional level are substantiated, which presupposes a mathematical model of these processes through the development of a system of equations, which depending on the tasks determine either the timing of the outlined phases of solving waste management issues based on available investment resources, or the amount of funds required to ensure proper timing of the innovative disposal facilities commissioning.

Malaysia recorded 8904 coronavirus disease (COVID-19) cases and 124 deaths as of 27 July 2020. Globally, everyday there are thousands of new cases of COVID-19 being recorded. Due to the high number of infections globally and nationwide the increase in the amount of clinical waste (CW) generation was expected. Malaysia has reported a 27% (by weight) increase in the generation of CW which was mostly attributed to COVID-19 related waste. This article presents the impacts of COVID-19 in waste generation, policy and regulation of CW management (CWM) in Malaysia and a case study on the CWM at a selected hospital used as a COVID-19 focal point. The current practice of CWM due to COVID-19 related cases follows the existing policy and legislation of CWM detailed in the Schedule Waste Regulation (2005), Environmental Quality Act, 1974, and with the standard operating procedure provided by the Ministry of Health, Malaysia. The case study conducted through survey and questionnaire interviews revealed that the CWM in government hospitals followed existing guidelines for CWM for COVID-19 waste, with some additional precautions and rules by the waste management contractors.

Energy shortage is the main problem while preparing food at the university in Ethiopia. Baking of injera consumes a lot of firewood due to the nature of baking mitad and layout of the system. The daily average firewood consumption is 8600 kg which is equivalent to 790.3 m3 of gas. In this study, an investigation of energy yield from food waste is examined by assessing the daily waste generation rate from the university student cafeteria and configuring the baking stove (mitad) that utilizes biogas energy. CFD is used to investigate the performance and heat distribution of baking mitad. In the study, the measured average daily biodegradable food waste and kitchen waste generation rate in the campus is around 863 kg/day. The conversion of this food waste using the anaerobic digestion system yields 43.2 m3 biogas per day. Utilizing the daily biogas generated for baking injera improves the overall food making process and reduces firewood consumption by 5.4%. This biogas energy yield is considered to be utilized for baking injera in the kitchen. The designed biogas mitad (stove) does not generate smoke due to the type of fuel used and configuration of baking mitad. Furthermore, the stove has an insulation mechanism considered to conserve the heat loss to the surrounding. Generally, the utilization of the biogas system and integration of the biogas injera baking stove will improve the overall food processing mechanism in the university.

In the era of cut throat competitive market, Indian industries are under tremendous pressure to continuously reduce the cost and improve product quality. The main objective of this research paper is to provide a road map for investigating the opportunities to reduce cost and improve productivity and quality in the existing production system through the application of Lean-Kaizen concept using value stream mapping (VSM) tool at shop floor of an Indian Small-Scale Enterprise (SSE). On the basis of collected data from the selected industry, a current state map was made. After analysis, the current state map was modified to develop a future state map. By comparing current and future state map, the gap areas were identified and takt time (TT) was calculated considering actual market demand. To overcome the gap between current state map and future state map and to synchronize cycle time of each station with talk time, Kaizen event (KE) was proposed. Fuzzy technology for order preference by similarity to ideal solution (TOPSIS) was applied to prioritize and select the appropriate KE for optimized performance level. After analysis of data obtained after application of the Lean-Kaizen concept, the final improvements in terms of improved productivity (57.15%) and reduced lead time (69.47%), reduced cost (65.61%), and station cycle time (75.25%) were recorded. Through the case study drawn from realistic situations of the industry, the authors highlight that implementation of Lean-Kaizen using VSM and fuzzy TOPSIS provides improvement opportunities across the organization. The findings can inspire the SSEs to adopt the Lean-Kaizen concept for optimizing continuous improvement opportunities in their production industry. This study offers the researchers and practitioners a good example for understanding, selecting, and performing KE program. They can even attain more improvement in various areas by establishing or improving these KE programs.

Bhaktapur Municipality has been performing better to keep the city clean. However, scarcity of space for the land filling of the solid waste and proper segregation of waste at the source has been a hurdle for the Municipality. This paper aims to determine solid waste generation rate and to analyze overall situation of solid waste management of Bhaktapur Municipality. However, the data will not represent the seasonal and occasional variations. Additionally, waste from street-sweeping and large-scale institutional and commercial components of the Municipality has not been assessed. Arkin and Colton (1963) was referred for the sample size determination. Sample of 376 households were taken accordingly. Twenty representative samples each for commercial and institutional establishments were selected, and one each for special cases such as hospital, slaughter house and poultry has been assessed. Municipal household waste generation was found to be 0.093kg per capita per day which was chiefly composed of 77% organic, 18% plastic and 3% paper. Organic waste has been a major waste for institutions such as schools whereas at governmental and public offices, paper is the predominantly generated waste. Among commercial establishments, shops and restaurants mostly generate organic waste and that for departmental stores has been paper. Though collection system was found to be satisfactory, treatment and final disposal have been unsustainable. Available treatment facilities have been shut down whereas other infrastructural components have been lacking.
