Waste Generation Rate

Background: The outbreak of COVID-19 has caused a devastating pandemic scenario in the world. The mortality rate has increased and new socio-economic challenges are emerging. Millions of gloves, gowns, face masks, and face shields are used daily to prevent airborne transmission and facilitate the treatment of COVID-19. Mismanagement of these wastes can lead to increased concerns due to their contamination potential. A comprehensive plan to improve the management of medical wastes in every country requires awareness of the current status of solid waste. As a result, the study aimed to calculate and estimate the consumption rate of face masks and medical waste generation rate during the COVID-19 pandemic in Iran. Also, the performance of different departments of medical waste management and future challenges are discussed. Methods: The daily consumption of face masks and medical waste generation were calculated based on the population data, the percentage of the urban population, face mask acceptance rate, the number of face masks needed per person per day, total COVID-19 confirmed cases, and medical waste generation rate (kg/bed/day). Results: The consumption of face masks in Iran is estimated at 46576000 pieces per day. Also, the three provinces of Tehran (9,560,000 pieces), Khorasan Razavi (3,825,600 pieces), and Isfahan (3,523,200 pieces) have the highest consumption rate of masks, respectively. Increasing the number of confirmed COVID-19 cases has increased the medical waste generation rate. Until April 3, 2021, more than 1,920,394 cases of COVID-19 have been confirmed in Iran, and calculations show that the medical waste generation rate in Iran is about 7,585.56 tons per day. Conclusions: COVID-19 is a highly infectious and problematic disease. The continuous increase in the number of confirmed COVID-19 cases has increased face mask consumption rate and medical waste generation rate, and as a result, new challenges have emerged in the field of solid waste management. These emerging challenges in managing solid waste during the COVID-19 pandemic necessitate the development of appropriate waste management policies and strategies.

The City

Lae city is the capital of the Morobe Province in Papua New Guinea. It is the main land transport corridor, the country's main industrial hub and largest cargo port. As a result of the urbanization and industrialization process, more people had migrated to Lae city for better opportunities. These activities contributed to the generation of a considerable amount of solid waste that has become a real concern. The present research aims to understand the existing practices of Solid Waste Management, to estimate per capita waste generation rate and composition of waste, to identify the issues and challenges faced in this regard and suggest methods for improvement. All wastes from the city are discarded at the Second Seventh Landfill (SSL) open dump site, located about 10 to 12 kilometers drive away from the city, causing enormous pollution to the surrounding environment. The per capita waste generation rate witnessed was 0.312 kg per capita per day with a composition of 66% organic waste, 22% recyclable, and 12% non-recyclable materials. It was found that ineffective legislation, lack of law enforcement were the challenges faced by the Lae city council. Rehabilitation of SSL or the construction of a new sanitary land fill should be recommended for effective management.

The objectives of this study were the assessment of healthcare waste management and the characterization of healthcare waste material generated in the hospitals in Nablus city, Palestine, and furthermore, to estimate the prevalence of hepatitis B among the cleaning personnel working in these hospitals. The medical waste generation rate in kg per bed per day was between 0.59 and 0.93 kg bed— 1 day—1. The waste generation rate in the healthcare facilities of Nablus city hospitals was similar to some other developing countries; however, the percentage of medical wastes in the total waste stream was comparatively high. The density of medical waste at the four hospitals studied ranged between 144.9 and 188.4 kg m— 3 with a mean value of 166.7 kg m—3. The waste segregation and handling practices were very poor. Other alternatives for waste treatment rather than incineration such as a locally made autoclave integrated with a shredder should be evaluated and implemented. The system of healthcare waste management in Nablus city is in need of immediate improvement and attention. Formulating rules and guidelines for medical waste and developing strategies for overcoming the obstacles related to waste management should be considered as an urgent matter.

It is necessary to assess solid waste generation to identify the rate by which we generate waste. A rapid increase in solid waste generation constitutes a significant challenge for developing countries such as Malaysia. Municipal Solid Waste (MSW) is the primary source of solid waste generated in Malaysia and covers 64% of the total waste composition. 45% of the average composition of Malaysian MSW is dominated by organic waste (e.g. food, vegetable and fruits). This is followed by recyclable waste (e.g. plastic, paper and metal) at 30% with the remaining made up of non-recyclable waste (e.g. polystyrene). The Fresh Market in Kundasang town, Sabah is a major contributor to the increase of organic waste generated in the Ranau district. As such, it has the potential to implement effective composting practices. This study was conducted to determine the total amount of organic waste generated as well as the organic waste generation rate in the Fresh Market. The sampling was conducted among 148 sellers in the Fresh Market over a period of two weeks (5th August - 18th August 2017). Total organic waste generation was 13,147.50kg, while the organic waste generation rate was 6.35kg/premise/day. The value for municipal solid waste generation recorded by Majlis Daerah Ranau (MDR) in three varied routes of Kundasang during August 2017 (Jalan Pekan Kundasang, Jalan Mesilou and Jalan Kota Kinabalu) were 17 tonnes, 15 tonnes and 13 tonnes respectively. This shows that the solid waste generated in Jalan Pekan Kundasang was the highest compare to Jalan Mesilou and Jalan Kota Kinabalu. This study presents the current status of organic waste generation which can serve as preliminary baseline information.

This work contributes to waste management from two major perspectives. Firstly, waste generation in a previously not-studied location—Awka municipality—was sampled and characterized. Secondly, the characterization was done with improved accuracy using a new method called zero-intercept first-order polynomial regression. The proposed method arrives at composition values and per capita values through polynomial regression that considers sampled waste generation data and household size as regressors, respectively. There are no constituents when no waste is generated and there is no per capita waste when household size is zero, therefore, zero-intercept was imposed on the proposed linear regression approach. An 820 by 11 data matrix from a ten-day sampling in Awka Municipality was used to illustrate the proposed approach; eighty percent of the data was used for training, while twenty percent was used for testing. The results from the proposed method proved more accurate when compared with traditional averaging techniques. The results established for the study area are equally in consonance with known results for similar Nigerian locations, such as organic (73.2%), plastic (8.0%), and recyclable (20.3%). The calculated specific loose volume, specific compact volume, the loose bulk density, and compact bulk density are 2.0 × 10−3 m3/kg, 9.9 × 10−4 m3/kg, 500.0 kg∙m−3, and 1010.2 kg∙m−3, respectively. The waste generation rate is 416.9 g/capita/day, the organic waste generation rate is 307.1 g/capita/day, the recyclable waste generation rate is 83.0 g/capita/day, paper and textile waste generation rate is 25.2 g/capita/day, loose waste volume rate is 9.02 × 10−1 dm3/capita/day, and compact waste volume rate is 4.51 × 10−1 dm3/capita/day. The solid waste characters were compared among the three income groups of low, middle, and high income earners and the observed trends are literature compliant with city-specific coloration. City-wide estimations were made based on demography, literature, and the established results that would aid waste management planning.

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.

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.
