Municipal solid waste is a growing concern in cities of developing countries and households are the main contributor. Lack of reliable data sources remain one of the major drawbacks for deciding on effective waste management option. The study area Gorkha municipality is selected because it is one of the highly under-researched and least resource intensive municipalities in Nepal. However, continued growth in municipal waste if left unattended will only intensify the problem and thus demands proactive action. Therefore, the objective of this study is to analyze waste composition and to evaluate the socioeconomic factors impacting household waste generation for effective management. Using stratified sampling method, 401 households were selected from all 15 municipal wards. Socioeconomic factors impacting household waste generation were assessed using Ordinary Least Square regression model. The rate of household waste generation in Gorkha municipality is found to be 0.24 kg/capita/day and estimated total household waste generation of 9.4 tonnes/day. Household size and income are found to have positive impact on waste generation, both statistically significant at 1% and thus can be important indicators to forecast solid waste generation trend. Household waste composition was 47.25% organic waste, 37.52% recyclable waste that comprised of 10.38% paper and paper products, 9.88% glass, 6.92% metal, 5.39% plastic, 3.57% textile and 1.38% rubber and leather, and rest 15.23% other waste. Organic waste has the highest share and if not managed properly, creates serious health and environmental hazards. It could be managed efficiently by composting at household and local government level.

Starting Point

The absence of accurate information on the state of waste is a challenge to the solid waste management system in Syria. The local authorities commonly estimate the quantity of waste produced and its characterisation, which is the starting point for solid waste management planning. So, this paper aims to evaluate the generation and composition of household solid waste in Homs city, Syria. Also, the study presents factors influencing the waste generation rate and the waste composition. The study was carried out in 300 families from four zones in Homs city, and three sampling stages were conducted during the study duration, which started in July 2017 and ended in February 2019. The outcomes show that an average of 0.68 kg/per/day solid waste generated was calculated for the entire study area in Homs city. Also, the data analysis presents that organic waste constitutes the largest component in the waste mixture (69.1%) followed by plastic (10.6%), inert materials (8.7%), paper (4.6%), textile (2.5%), metal (1.2%), glass (1.1%), wood (0.6%), and hazardous materials (1.6%). The multiple linear regression results showed that the adjusted R2 value was found to be 0.557, 0.839, and 0.709 for the waste generation per capita, the daily household organic waste generation, and the daily household packaging waste generation, respectively. Also, according to Pearson’s coefficient values, a positive correlation was found between household waste generation and monthly income (r = 0.626), household size (r = 0.37), and age of the household head (r = 0.517), whereas a negative correlation was found between household waste generation and the education level of the household head (r = −0.649).

Waste Generation Rate

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.

Waste management, being one of the most important aspects of urban development, is gaining importance among developing nation like Nepal where rapid population growth, unmanaged urbanization, lack of public awareness and poor management by municipalities have intensified environmental problems in towns in Nepal. In Nepal only six municipalities i.e. Kathmandu, Lalitpur, Pokhara, Dhankuta, Tansen and Ghorahi practice sanitary landfill for waste management and other municipality practices open dumping which has become major cause of environmental and human health hazards (ADB, 2013).Jeetpur Simara Sub-Metropolitan City (JSSMC) is a recently formed sub-metropolitan city. This city has not performed any study on solid waste management till date and lacks data on quantity and composition of municipal solid waste generation that facilitates effective planning of municipal solid waste management. The household survey revealed an average per capita household waste generation rate of 120 g/capita/day. The total Municipal Solid Waste (MSW) generation is estimated about 15 tons/day and 5475 tons/year. The analysis of household waste composition indicated that the highest waste category was organic waste with 80% followed by plastics with 10%, paper and paper products with 6% and inert with 4%. The composition analysis of institutional wastes revealed 41% paper and paper products, 33% plastics, 13% organic wastes and 13% inert. The study found that commercial waste comprised 59% paper and paper products, 21% plastics, 17% organic and 3% inert. In aggregate, MSW is composed of 56% organic waste, 21% paper and paper products, 19% plastics, and 3% inert. HYDRO Nepal JournalJournal of Water Energy and EnvironmentIssue No: 22Page: 45-47Uploaded date: January 14, 2018

Set Up

This study was conducted to set up a new reference line for municipal solid waste quantification and characterization in the least urbanized cities of a developing nation. A survey was run to collect baseline data from 60 new municipalities of Nepal. The study covered a sample size of 3300 households, 600 institutions and 600 commercial establishments in those municipalities. The municipalities were further stratified according to geographical location, the degree of urbanization, household expenditure and population size to assess the influence on waste generation. The results indicated that the average per capita household waste generation is 115 g day-1 while the average total municipal waste generation was estimated to be 180 g day-1 per capita.The study also revealed that size of municipal population, geographic location, household expenditure and degree of urbanization were found to have a significant influence on the unit waste generation. The larger the size of municipal population the higher the per capita household waste generation, degree of urbanization and per capita waste production. Increasing household expenditure revealed an increase in the unit waste generation. The waste categories included organic waste, plastics, paper and paper products, textiles, rubber and leather, metals, glass, and others. The results indicated that organic waste dominated the characterization (62%), followed by plastics (12%) and paper/paper products (11%).

This research examines the effect of enterprise risk management on firm value in Pakistan. Further, this study empirically examines company characteristics that establish the execution of an enterprise risk management system. Using a sample of final dataset of 83 non-financial firms located in Pakistan. The sample included non-financial firms from the year 1999 to 2015 and so up to seventeen observation years per company. As in context of Pakistan, most of the organizations are already implement an ERM programs and establish specialized ERM departments because the ERM is now a global term and has become increasingly relevant because of the growing difficulty of risk and an additional development of regulatory frame works. For the empirical evidences, data collected from non-financial firms listed at the Pakistan Stock Exchange (PSX). Results of logistic regression shows that Capital Opacity, Profitability, Financial Leverage, Firm Size and Slack have positive impact on the implementation of an ERM system but Industrial diversification, Industry and Return on Equity are negatively related to an ERM engagement. The results of ordinary least square regression finds positive relationship between use of an ERM and firm value.

The Impact

This study is an empirical investigation to assess the impact of domestic debt on India’s Economic growth during the period 1980 – 2014. We use data on Domestic Debt, Net Fiscal Deficit, Exports, Savings, Real Gross Domestic Product, Population and Terms of Trade. This study adopts the ARDL Co-Integration and Granger Causality techniques to investigate the relation between the key variables. The study also employs various post estimation tests to validate the fitness and stability of the models based on Gauss Markov assumptions, after employing the ordinary least square regression on various models. We find that debt negatively impacts economic growth while savings has a positive impact. The Auto Regressive Distributed Lag (ARDL) technique used to test the robustness suggests existence of co-integration among the variables. However, none of the long run co-efficient is significant. The granger causality and co-integration test results support the traditional view that debt negatively impacts economic growth.

Waste Generation Rate

This study has employed multiple techniques, including subjective and objective approaches, to augment existing information and data on household waste generation, generation rates, composition and waste management perceptions in informal settlements. Waste weight, volume and composition data were obtained through one measurement study (n=80) and five surveys (n = 1,239). Additional information was obtained through physical observations and interviews. Results of this study revealed per-capita overall mean weight and volume to be 0.51 kg/day and 1.33 liters/day, respectively. Relatively higher per-capita daily waste generation rates were observed in smaller households, suggesting a positive dependence of municipal solid waste generation rate on both household income and size. Generation high points were on Mondays, signifying that accumulation of waste is more on Sundays perhaps because of shopping during weekends. Organic waste constituted the largest component (60.5% by weight), while e-waste constitute the least (0.4%). About 43% and 8% of the population have to store the waste for two to three weeks and for more than a month, respectively, before delivery for collection by the local government and or the private sector. The study established existence of both extreme satisfaction and dissatisfaction with waste collection and significance of collection problems in the informal settlements.

A complicated problem for big city governments today is the increasing volume of solid waste, due to population growth and mobility so that the waste load will also increase, especially in metropolitan cities such as Makassar City. To reduce the rate of organic waste generation, which is 60%, is to use organic waste as compost, both liquid and solid. The purpose of this study was to compare the effectiveness of composting with EM4 and MOL activators. The results of the study with the addition of EM4 activator, MOL activator and without the addition of activator from the first day to the fourteenth day the compost structure was different. The addition of MOL produces a slightly coarser structure compared to the addition of EM4, while the compost without activator still smells like wet waste. The quality (C/N) of compost, the addition of 100 ml of EM4 was in the optimum level, while the addition of 100 ml of MOL was less than optimum.

<p>Waste management in the Dasan Agung Market in Mataram City still uses conventional patterns. This pattern is not in line with the NTB Province policy that launched the concept of zero waste in 2019-2023. One approach that can support the program is the 3R method of waste management. This study aims to develop a waste management plan using the 3R approach. The method used in this study is the observation method, which is observing the current conditions and measuring the generation and composition of waste. The technique of determining the sample and measurement time and the procedure refers to SNI-19-3964-1995. The results showed that the amount of solid waste generation in Dasan Agung Market was 2.7 m<sup>3</sup> / day and the weight of solid waste was 467 kg / day. Waste composition was obtained by organic waste 52.60% and inorganic waste 47.40%. TPS 3R is planned with an area of 110 m<sup>2</sup>, namely 74 m<sup>2</sup> for composting area and 36 m<sup>2</sup> for sorting and handling inorganic waste, and residual waste. The composting system implemented is using the drum method with a capacity of 100 liters, a total of 307 pieces. Waste Management Planning using the 3R Approach is capable of handling 80% of the waste, and 20% of the residue is disposed of in the landfill.</p>
