The main objective of this research was to investigate the waste characteristics and management activities in the Savojbolagh industrial zone, Iran, in order to rank the active industries from environmental perspectives using an innovative index. First, the industrial categories with over 50 employees were identified and classified according to their production process. Then, 54 industries were selected and all industrial processes, the types and quantities of products, per capita industrial waste generation, physical analysis and management activities in terms of minimisation, storage, processing, recycling and disposal were evaluated. The required data were obtained through questioners, interviews and field observations. A scoring system was prepared for evaluation of environmental status of waste management practices. Results indicated that the total industrial waste generation rate was 67,258 kg d-1, in which 4528 belonged to hazardous waste. Furthermore, the per capita waste generation rate was 5.51 kg d-1. Plastic, paper and cardboard and metals constituted the most fractions of wastes, respectively. Food and beverage, metallic and chemical/plastic industries were the biggest waste generators. Metallic industries with total score of 502.5 and non-metalic-mineral industries with the total score of 114 were categorised as the best and worst industries in terms of waste management practices.

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.

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.

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.

Waste Generation Rate

Background: Biomedical wastes (BMW) generated from medical laboratories are hazardous and can be deleterious to humans and the environment. Highly infectious types of biomedical wastes are commonly generated at an unacceptably high rate from health laboratories of developing countries with a poor management system like Ethiopia. This study was aimed to evaluate the generation rate of biomedical wastes, management practices, and associated factors among public healthcare medical laboratories in Addis Ababa, Ethiopia. Materials and methods: A Health institution-based cross-sectional study was conducted from July 13 to September 25, 2020, in 6 hospital laboratories and 20 health center laboratories in Addis Ababa, Ethiopia. Data on socio-demographic characteristics, knowledge, and practice of biomedical waste management of the health facilities, Biomedical waste generation rate were collected using data collection tools. Data were managed using SPSS version 20 software. Descriptive statistics, Pearson correlation, linear and logistic regression analysis were computed to identify independent predictors of the dependent variable. An Odds ratio with a 95% confidence interval was used to determine the strength of association. Results: The finding revealed that the mean plus or minus SD of the daily generation rate of biomedical wastes was 4.9 plus or minus 3.13 kg/day per medical laboratory. Nineteen (74.3%) medical laboratories had a proper practice of biomedical waste management which is significantly associated with knowledge of professionals on biomedical waste management policies and guidelines, availability of separate financial sources for biomedical waste management, and training level of professionals. Conclusion: The study showed a high generation of biomedical waste from medical laboratories in public healthcare in Addis Ababa, Ethiopia. Near two-thirds of health facilities had a proper practice of waste segregation, collection, storage, and treatment of biomedical wastes generated from their laboratory. However, there was a poor practice of transportation and disposal. Hence, due attention and practicing as per the current national guidelines of biomedical waste management is recommended.

This paper examines the influence of population growth on waste generation in Lagos metropolis, African’s most populous urban conglomeration. Using both quantitative and qualitative methods, the study analyses the pattern of household waste disposal, collection and transportation in Lagos State. It also examines the public-private partnership strategy adopted in waste management. The findings show that population growth significantly influences waste generation and management in Lagos metropolis. As the population increased, the volume of waste generated also increased in each LGA of Lagos State. The public-private partnership strategy has been effective in managing waste, but the Lagos State Waste Management Authority oversight was adjudged as less than satisfactory. The paper concludes that intervention is needed in terms of educating the growing population of the Lagos metropolis on the best waste management practices. It highlights the need for a more efficient and effective publicprivate partnership collaboration to solve this perennial social problem.

Protecting the occupational environment is a top priority in manufacturing of any kind of products and provision of various types of services. Environmental protection plays a significant role in the mining industry, as increasing extraction of minerals involves growing amounts of waste and environmental pollution. In 2019 alone, industrial waste generation in the Russian Federation peaked at 7.75 billion tonnes. AZOTTECH LLC is currently handling industrial waste associated with the production and use of chemicals for drilling and blasting operations, scrap from machine-building plants, etc. The article reports on the volumes of industrial waste of each hazard class for 2019-2020 and provides a forecast of the volumes for 2021. The reduction in volumes has been achieved through the implementation of a waste management system. In addition, the paper presents statistics on the reduction in the disposal costs, calculated according to the tariffs of each region where the company's subsidiaries are located. An analysis of the factors reducing the volume and cost of waste management has been performed. Upon implementation of the waste management structure, the costs decreased by 2.5 times, and the amount of waste was reduced by two times.

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.

Hospital waste management is of vital significance owing to its contagious and hazardous nature as it can produce detrimental effects for both humans and the environment. This work aimed to examine types of waste with respect to waste generation rate in multiple teaching hospitals of metropolitan Lahore. A structured questionnaire survey, site visits, interviews and meetings were conducted in seventeen teaching hospitals. The results have shown that total hospitals average waste, infectious, non-infectious and waste generation rate in Lahore teaching hospitals were 38978 kg/day, 10789 kg/day, 28189 kg/day and 3.7 kg/bed/day, respectively. It is concluded that maximum waste generated in Mayo hospital, Jinnah hospital, Services hospital and Lahore general hospital was 16%, 12%, 12% and 10%, respectively, as per maximum patient’s visits. Positive liner correlation was between number of beds (P=0.917), number of accidents and emergency patients (P=0.75), infectious waste (P=0.998) and (P=1) with total waste. A straight line of linear regression was between (0.9966) infectious waste and (0.9995) general waste with average waste. Although, waste collection practices in these teaching hospitals were observed satisfactory but required training of doctors, nurses and hospital paramedical staff regarding infectious and general waste segregation. It is suggested that hospital staff, waste management and waste collection workers and respective waste management companies should be well trained and aware regarding infectious and non-infectious waste segregation, handling and disposing off procedures.
