This qualitative study explored the management of waste in commercial and training dental laboratories in order to determine the practices and attitudes of dental technology practitioners and academics towards reusing and recycling dental laboratory waste products, and alert them to the benefits of waste management on the environment. The research objectives were to establish and report on the extent of waste management that entails waste reduction through reusing and recycling, to uncover alternative uses for dental laboratory waste and the possible economic benefits thereof and to influence dental technology industry on environmental sustainability. The research project was conducted in the interpretive paradigm. In the course of this study dental laboratory owners, dental technicians/technologists and academics from the dental technology programme at a training institution were interviewed. Waste handling in dental laboratories was observed in order to gain greater insight as to current practices in laboratories. Thematic content analysis was employed to analyse the qualitative data. This study found that waste management was poorly understood and practiced amongst the dental laboratory owners, dental technicians/technologists and academics. The study adopted a waste management hierarchy conceptual framework which was influenced by the Waste Act (Act No. 59 of 2008). The negative attitudes towards responsible waste management practices and the poor understanding of waste management by dental laboratory owners, dental technicians/technologists were found to be as a result of the poor understanding of the possible impact that waste from dental laboratories can impose on the environment. The perceived lack of participation in constructive waste management legislation by the South African Dental Technicians Council was also seen to be a contributing factor to the negative attitudes towards responsible waste management practices within the industry. This finding reinforced the finding that the dental industry has no knowledge, understanding and desire to understand waste management and, more importantly, to understand that one does not practice things solely for legislative reasons but that there are economic as well as environmental reasons to practice constructive waste management. On the other hand, this study found that the industry was not averse to engaging in environmental friendly practices provided there is financial gain. This was established after the benefits of waste management practices were explained to the industry.

Agricultural Waste Management

A study was conducted to assess the present status of agricultural waste management by farmers in Trishal upazila of Mymensingh district, Bangladesh. During April to May 2015 and data were collected from the sample of 70 farmers and 5 farms. A structured interview schedule was used for collection of data. The study explored the relationship between the four selected type farming (independent variable) of farmers with their generation of agricultural waste (dependent variable). In this study the highest amount waste (straw and husk production) is closely related with the size of cropland. Straw production less than or equal 1000 kg is 36.62%, straw production less than or equal 10000 kg is 54.92%, straw production less than or equal 20000 kg is 5.63% and straw production less than or equal 30000 is 2.81% and husk production less than or equal 1000 kg is 35.71%, husk production less than or equal 10000 kg is 55.71%, husk production less than or equal 15000 kg is 8.57%. So as the dairy and poultry waste is also relate with the number of cows and birds. Average amount of dung is 8.87 kg per day and average amount of used litter was 46.36 kg per 800 bird production. For management biogas was suggested by 12.5 percent respondent. Composting and fish culture were suggested individually by 4.17 and 8.3 percent respectively. Due to manage agricultural waste efficiently it is necessary to initiating program to introduce the economic benefits of waste management and start training programs for farmers.Res. Agric., Livest.

Waste Management Practices

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.

Waste Management Practices

Hong Kong is a densely populated city with high-rise developments, and as in other metropolitan cities, the amount of waste generated from construction projects in the city is increasing annually. The capacity of existing landfills is expected to be saturated by the 2020s. Construction waste management has been implemented for years but the performance is still not satisfactory. The aim of this research paper is to explore and formulate strategies and measures for effective construction waste management and reduction in highly urbanized cities such as Hong Kong. A desktop study on construction waste management practices was carried out for a preliminary understanding of the current situation in Hong Kong. Semistructured interviews and focus group meetings were further conducted to shed light on how to improve construction waste reduction and management in Hong Kong. The main contributions of this research study are the potential short-term, medium-term, and long-term strategies, which are related to the design stage, tender stage, construction stage, and government support. The five major strategies recommended are financial benefits to stakeholders, public policies in facilitating waste sorting, government supports for the green building industry, development of a mature recycling market, and education and research in construction waste minimization and management.

Waste Management Practices

The waste management practices in primary healthcare centres of Iran were investigated in the present study. A total of 120 primary healthcare centres located across the country were selected using the cluster sampling method and the current situation of healthcare waste management was determined through field investigation. The quantities of solid waste and wastewater generation per outpatient were found to be 60 g outpatient—1 day—1 and 26 L outpatient—1 day— 1, respectively. In all of the facilities, sharp objects were separated almost completely, but separation of other types of hazardous healthcare solid waste was only done in 25% of the centres. The separated hazardous solid waste materials were treated by incineration, temporary incineration and open burning methods in 32.5, 8.3 and 42.5% of the healthcare centres, respectively. In 16.7% of the centres the hazardous solid wastes were disposed of without any treatment. These results indicate that the management of waste materials in primary healthcare centres in Iran faced some problems. Staff training and awareness, separation of healthcare solid waste, establishment of the autoclave method for healthcare solid waste treatment and construction of septic tanks and disinfection units in the centres that were without access to a sewer system are the major measures that are suggested for improvement of the waste management practices.
