Organic waste composting is an important waste management practice that can reduce the volume of municipal solid waste and increase crop productivity. A study was carried out in Madhyapur Thimi, Bhaktapur in order to develop understanding of different methods of composting for sustainable solid waste management practices. Solid waste was collected randomly from 50 households in the area and segregated manually. The biodegradable waste was composted through pile (aerobic), aerobic bin, anaerobic (pit) and vermicomposting process. The physico-chemical and microbial analysis of composts were carried out in laboratory whereas significance of composts on crop productivity was tested in the study area. The study showed that 81.4% of the waste generated was biodegradable. The physico-chemical and microbial analyses of the compost samples showed pH range of 7.6 to 8.2 and moisture content of 54.5% to 69.5% for different composts. The maximum temperature (62°C) was observed in aerobic (pile) composting. The nutrient analysis (oganic matter, nitrogen, phosphorus, potassium and C: N ratio) of different composts showed that vermicompost was the most among all the composts. The total bacterial and fungal count varied from 3.91 x 104 to 8.05 x 106 cfu/g and 1.30 x 103 to 3.25 x 104 cfu/g respectively. The vermicompost was found rich in microbial population too. The application of vermicompost at 6.25 mt/ha in the study area resulted in increasing in height, diameter and yield of cauliflower by 15.62%, 37.58% and 38.95% respectively over farm yard manure. The height, diameter and yield of cauliflower grown in different composts was found to be significantly different (P<0.05).

Purpose Municipal solid waste (MSW) consists mainly of several recyclable materials such as paper and cardboard. Inside the educational institutes, especially universities, MSW is generated from several facilities including offices and cafeterias. Without an effective management program, solid waste can have detrimental impacts on the environment. This paper aims to assess the solid waste management practices followed at the main campus of Imam Abdulrahman Bin Faisal University (IAU), Dammam – Saudi Arabia. Design/methodology/approach The MSW samples were collected from different sources inside the IAU campus such as the college buildings (such as the teaching rooms and staff offices), the administrative buildings and services buildings (e.g. the main library, the photocopying center, the restaurant and cafeteria) at least one time per week during a full academic term (January–May) of the academic year 2017–2018. The collected MSW samples were segregated into seven categories, and the net amount of each category and the overall weight of the MSW were determined once every week. The MSW samples were characterized for physical and chemical properties including moisture, carbon and ash contents. Food product waste (FPW) of the main university restaurant was studied separately. Findings Data on the composition of MSW samples revealed that 80% of wastes were recyclable, 19% as compostable materials, while only 1% of the materials were a non-recyclable waste. More than 73% of the recyclable materials include paper and plastic warranting dire need of an effective solid waste management program. The highest value of FPW was recorded for the breakfast meal. Originality/value Most of the waste generated from the university campus was recyclable type that needs to be handled carefully to avoid its mixing with other types of the waste stream. Waste characterization is an important tool that helps in understanding the amount and pattern of waste generation. It can be used as a decision-making tool for implementing sustainable waste management programs for universities.

Solid waste management system is the most difficult task that many countries face. The aim of this study was to evaluate the effectiveness of solid waste management practices of households and analyze dumpsites' environmental suitability in Debre Markos town. Primary data were collected from randomly selected households using structured questionnaire and from secondary data from different bureaus, from research and other reports in 2017. Qualitative and quantitative techniques were used to evaluate solid waste management practices. Data were analyzed using statistical package for social Science and Geographical Information System computer program. The results revealed that households dominantly produced biodegradable solid wastes (87.6%) with the generation rate of 0.3 kg/person/day. This made the daily total solid waste generation of households up to 6210 kg (17 m3). The suitability map of the area for landfill showed that 1.4% of the study area was highly suitable, 36% was moderately suitable and 58% was less suitable. Moreover, 4.7% of the area was found unsuitable to be used for waste disposal. In conclusion, sustainable solid waste management systems must be executed, the structure and capacity of the municipality improved and integrated solid waste management practice must be applied for a healthy environment. Moreover, the municipality should make dumpsites environmentally sound and socially acceptable to decrease impacts of solid wastes on the communal land, on human, on animal and on environmental health.

This study aims to present waste characterisation, solid waste management practice and analyse the challenges in the solid waste management system in the tourism destination of Hoi An City, Vietnam. The sampling and questionnaire surveys were conducted for measuring characterisation and management practice of solid waste. A material flow analysis method was used for analysing the waste flow. The results show that the tourism destination generated daily around 15080 kg t of waste, in which the significant proportions come from restaurants (46%), hotels (22%) and households (13%). The feature of the waste composition is high rates of kitchen waste (46.8%), tissue (11.54%) and recyclable materials (12.58%), which result in high moisture (46.79%) and a low heating value (16,866 kJ kg-1) of waste. Also, solid waste management practices were evasively implemented by stakeholders with low rates and efficiency. Furthermore, a substantial gap of the solid waste management system is the confusion in waste collection activities, which is shown by the overload of waste in street bins and the financial loss for the solid waste management system owing to the non-compliance with collection regulation of stakeholders. Also, the mixing of waste by collection crews after separation at sources, the in-appropriation of collection time and manner are the dark points of the solid waste management system that may be causes of the non-cooperation of stakeholders. These gaps and confusion in the solid waste management system are the significant challenges in the improvement of the solid waste management system in the tourism destination toward sustainability.

Recently we conducted a study to evaluate the existing solid waste management practices at Institute of Business Management (IoBM), Karachi which shows that the institute possesses best management practices related to solid waste collection, transport, segregation, recycling/reuse, and final disposal. Adequate number of color-coded bins have been laid at appropriate locations throughout the university campus. Institute has enough staff for waste management including waste collection, transportation, and disposal. Results of our study indicate that about 2,033 kg of solid waste/month (24.5 tons/annum) is generated from the IoBM campus. Out of the total, about 67.8 % is the recyclable and reusable plastic, paper, and metal waste while, the remaining (about 32%) is mostly organic waste generated from various facilities of the university. Economic analysis indicates that about 252,012 Pak rupees annually are earned from selling the recyclable and reusable inorganic solid waste. Study also indicate that about 500 kg of good quality compost per month can be prepared from the organic waste including food and yard waste that can be used for existing horticultural activities at the university. Moving towards a sustainable integrated solid waste management system necessitates improved system of waste collection, segregation, reselling, and composting

Waste Management Practices

This paper presents an overview of the current solid waste management practices in Gashua town and provides a brief discussion on future challenges. Gashua town the headquarters of Bade Local Government Area since 1949. Since then the population has mainly due to the influx of people and its strategic location along the axial route to significant towns in the state. Wastes are generated mainly from residential, commercial and institutional land uses. Waste collection sites are strategically situated as identified by the agency and designated as high waste generating points, metal waste bins and constructed waste bunkers. The contents of these bins are finally disposed of at a location 6kilometres away from the generating points. Spatial data on waste distribution was collected using a global positioning system (GPS). The data was manipulated and processed using a Geographic information system (GIS) to produce the waste distribution map. Findings revealed that the existing solid waste management system is inefficient as the present practice relies on monthly collection and disposal of waste using an open dumpsite.

Factors Affecting

The problem associated with the household behavior on solid waste disposal site in today�s society is complex because of the large quantity and diverse nature of the wastes. Due increase the population, rapid development, global agricultural development has moved rapidly, limitations of financing, emerging limitations of both energy and raw materials and also add to the complexity of any waste management system, large quantities of wastes are being generated in different forms such as solid, liquid and gases. This research explored factors affecting the level of participation in solid waste segregation and recycling of households in Romania, as well as examining current Romania households waste management practices and their knowledge of waste management. This study investigated the solid waste situation and the organization of solid waste management in both urban and rural settings from the perspective of households. Solid waste management is a key component of public services which needs to serve the urban and rural municipalities in an efficient way in order to maintain a decent standard of public health.
