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.

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).

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.

Solid waste problem is happen in many big city, such as Surabaya City. Jemur Wonosari which is participant in Surabaya Green and Clean (SGC) program also have waste management problems. When SGC was conducted, solid waste management is good. However, after the program finished, solid waste management facilities was neglected. In this research we measured solid waste measurement in waste generation and composition from domestic and non-domestic. Also to survey the level of community participation in manage solid waste. The design is quantitative research, data getting from measurement of waste generation and composition also question data to know community participation level in waste management which influenced by internal factors (knowledge, motivation, and environment attitude).The result of research, waste from people in a day is 0,093 kg/person/day. The result of solid waste generation which produced by the community is about 2054,37 kg/day. Waste composition which dominated by food waste, it’s about 43,3%. From the X2 test explain that there is a relation between knowledge, motivation, and environment attitude to community participation and between community participation to solid waste management. The community need to improve composting activities to minimize waste and rise up community participation.

Waste Generation Rate

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.

Reduction Effort

Surabaya has become one of the cities in Indonesia with the largest volume of solid waste. One way to reduce waste generation in Surabaya City is through waste banks. The number of waste banks in Surabaya is 374 units since 2012, with 0.55 ton/day or a 0.05% reduction effort against total waste. The non-organic municipal waste potential that can be utilized is 40% and the total waste reduction for non-organic waste is 0.13%. The unit price of each type of solid waste is one of the main factors in people’s willingness to sell their solid waste. The higher the price of the waste, the more revenue they will earn. This research is focused in South Surabaya where the greatest number of waste banks is located. Based on typical mass balance analysis, the total waste that can be reduced is 20% for compostable waste and 18.24% for non-compostable waste. Meanwhile, based on research, the total waste is reduced by 10.16% for compostable waste and only 0.343% for non-compostable waste. The reduction potential occurring through the waste bank activities is 0.146% of the total generation of 237,801.9 kg/day. The reduction percentage needs to be increased so that the volume of municipal waste can be suppressed. Therefore, there must be an effort to improve the performance of waste banks or to increase the number of waste bank units.

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%).

The hospital's domestic solid waste increases with the increase in the number of hospitals. Zero waste initiative can potentially reduce waste to be disposed of in the TPA. The resulting solid waste consists of various compositions that can be used to seek potential for reduction, reuse or recycling. Domestic solid waste generation is calculated using the SNI 19-3964- 1994 approach, samples are taken from kitchens and non-kitchens. The composition of waste is sorted by type and the potential for zero waste seen from the composition. The waste generated by hospital is 0.39 kg/bed/day for kitchen, 1.08 kg/bed/day for non-kitchen and for all source of waste total 1.47 kg/bed/day, lower than the WHO standard 3.2 kg/bed /day. The composition of the waste were plastic (17.66%), papers (8.25%), organic waste (43.99%), metal (0,41%), cardboard (9,37%), residue (17,61%) and others (2,71%). Bandung Adventist Hospital has started several efforts to minimize waste. Zero waste application with separated waste can then be processed according to the characteristics of each type of waste. Plastic, paper and cardboard waste can be separated for recycling. Organic waste in the form of food scraps such as rice can be separated for animal feed, digested and composted.Keywords: composition, hospital, domestic waste, minimize, zero-waste,
