“…Firstly, the ways of obtaining data in this study are different from previous studies. De Vega et al [9], Smyth et al [8], Adeniran et al [13], and Gebreeyessus [14] collected sample wastes and analysed the waste composition and recycling potential. Zen et al [18] gained data through student research, collaborative works with Unit of Sustainability and waste contractors, while this study employed face-to-face interviews with people who handle the solid waste (mainly cleaners) to acquire data.…”

“…He found that the waste generation on this campus was 32.7 tonnes per day, of which 39% was plastic waste, 15% was organic waste, 15% was paper, 8% was soil and stone, 7% was sanitary waste, and 75% of the waste was recyclable. Gebreeyessus et al [14] looked at the Kotebe Metropolitan University in Ethiopia. They applied a range of equipment, such as labelled baskets, weighing scales, and transfer carts, to determine the composition and generation rate of solid waste.…”

Waste characterization is the first step to a successful waste management system. This paper explores the trend of solid waste generated on a university campus (Longzi Lake Campus of Henan Agricultural University) in China and the factors that influence the potential for recycling of the waste. Face-to-face interviews were carried out for 12 consecutive months on a campus in central China, and 416 interviewees were questioned. It was found that 7.32 tonnes of solid waste were generated on the campus each day, of which 79.31% were recyclable. The characterization of major waste streams are discussed, and the results are compared with comparable data from five universities in a range of other countries (Mexico, Canada, Malaysia, Nigeria, and Ethiopia). The annual growth of GDP per capita in China over the past five years before the research appeared to play an important role in the increasing of food waste on university campus, and the proportion of food waste is found to have a positive influence on recycling potential.

“…The increasing presence of non-biodegradable and hazardous waste types means that safe collection, transportation and disposal are absolutely crucial for public health sustainability. Since, indiscriminate and improper dumping of Municipal Solid Waste (MSW), in particular, widespread dumping of waste in water bodies and uncontrolled dump sites, aggravates the problems of generally low sanitation levels across the African continent [18].…”

Background: Waste is a byproduct of human life. Nowadays, municipal solid waste is being produced in excessive amounts and in this way, both developing and developed countries are facing challenges regarding generation of waste. Economic development, urbanization and improved living standards in cities have contributed to increase in the amount and complexity of solid waste produced. Methods: this study aims to Analysis of households' willingness to pay for improved solid waste management Services in Gondar city, Ethiopia: evidence from a double-bounded dichotomous contingent Valuation Method.Result: A total of 222 randomly selected households were interviewed to address the objective of this study. Finally, the survey result indicated that 192(87.3%) of sample households were willing to pay for improved solid waste management services. Following this, the one and double-bounded dichotomous contingent valuation result revealed that the mean willingness to pay estimated from the Double Bounded dichotomous CVM and open ended formats were 34.48 and 17.0756 ETB[1] per month per households respectively. The total WTP was obtained by adding the WTP of the total households in each stratum, and is equal to 941361ETB and 1900848 ETB for open ended and double bounded format, respectively. Additionally, the bivariate probit model result demonstrated that income and education have positive and significant effects on willingness to pay bid amounts. The results, age, marital status, Bid1 and Bid2 have a negative and significant effect on households’ amount of willingness to pay for better solid waste management services. Conclusion: When allocating service charges the city municipality considers amount of solid waste generation and income level of the households. The study results show that when educational status of the households increases and increase their willing to participate in planned improved solid waste management service. Thus, awareness creation is importance for better solid waste management. Additionally the city municipality facilitates a learning media for uneducated households to come up with at least secondary education level.

“…At thecombined campus of CCSHAU and LUVAS a total of sixty five solid waste generation points were identified and categorised in different activity units as mention in Table 1. The overall sample size of 44 was calculated using the formula (Gebreeyessus et al, 2019). n = N/(1 + N × x 2 ) Here n = sample size; N = total number of generation point x = level of precision (0.1) The solid waste generation was calculated with the help of the sanitary staff andweighing through spring balance (WMC-461265, ELEF INDIA).…”

Effective management strategy is required for handling the large quantities of waste produced by various societies/ organizations and waste characterization is essential to prepare this management policy. In this study, solid wastes collected from the combined campus of Chaudhary Charan Singh Haryana Agriculture University (CCSHAU) and Lala Lajpat Rai University of Veterinary and Animal Science (LUVAS), Hisar was characterized through population estimation, field investigations and applying ASTM D5231-92 standard method. In the combined campus, the average quantity of solid waste generation was found to be 1047.1Â±214.4 kg/day. The whole campus was divided into five structural units and waste composition was determined, mixture unit waste comprised the highest fraction of food 62.13% and polythene 10.8%. The statistical estimation obtained a strong positive correlation of mixture unit waste with residential and markets waste contents, which was 0.995 and 0.997 at p<0.01. The analysis of solid samples showed that the biodegradable part of solid waste may be a better source for composting while some content of non-biodegradable waste can be sold into the market for recycle or reuse purpose. On the basis of solid waste characterization, a set of recommendations were suggested to strengthen the waste management processes for institutions.
