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.

Biomedical waste or hospital waste is any kind of waste containing infectious materials. It may also include waste ass ociated with the generation of biomedical waste that visually appears to be of medical or laboratory origin (e.g. packaging, unused bandages, infusion kits etc.), as well research laboratory waste containing bio molecules or organisms that are mainly restricted from environmental release. The pre-experimental study was conducted on 40 nursing students in Chief Khalsa Diwan International Nursing College, Amritsar. Prior to structured teaching programme nursing students gave self-information and a self-structured knowledge questionnaire was used and evaluate the significant of difference between the two groups. The data obtained from study subjects was analysed and interpreted in terms of objectives and hypothesis of the study. Descriptive and inferential statistics was used for the data analysis. The study findings revealed that structured teaching programme was significantly effective in increasing the knowledge of Nursing Students of Chief Khalsa Diwan International Nursing College, Amritsar.

Introduction: Healthcare waste is the total waste both solid and liquid from healthcare establishment and laboratories. A hospital produces waste by giving their services to the patients. Purpose: This study examined the microbial load of waste from selected healthcare facilities in Aba metropolis, Abia State. Methodology: Tenfold serial dilution was used for processing of all the samples. After the dilutions, exactly 0.5ml of each the sample was planted on the media using the spread plate method and evaluated using the standard microbiological techniques. Results: The viable count (TVC) ranged from 1.0×103cfu/g to 0.3×108cfu/g, coliform count (TCC) ranged from 0.4×102 cfu/g to 4.2×104 cfu/g, staphylococcal count (TSC) ranged from 1.0×101 cfu/g to 1.4×102 and fungal counts ranged from 2.0×102 cfu/g to 0.8×103cfu/g in the microbial count of various waste samples within the Aba metropolis, Abia State. The laboratory waste had the highest microbial counts, followed by the Out-patient department waste and the least was the pharmaceutical waste. The microorganisms isolated from the hospital wastes were Staphylococcus aureus, Pseudomonas aeruginosa, Escherichia coli, Aspergillus niger, A. Fumigatus, Candida albicans and among others. Unique contribution to theory, practice and policy: This research has revealed that healthcare waste contained pathogens with high microbial load densities, suggesting that the hospital wastes may pose a major health and environmental threat, if not properly managed. The study recommends that, the government should ensure that there is a policy on hospital waste management in line with recommended international best practices, which should be monitored and enforced.

Chemical Wastes

Concern over the management of chemical wastes from laboratories has been gaining importance since the 1990s. For a good management of chemical wastes generated from laboratories, it is recommended that managers encourage an environment of cooperation and exchange, thus reusing chemical reagents. The institution under study implemented the Chemical Waste Exchange, whose objective is to capture reagents past their expiry dates that would be discarded and make them available internally to other areas or even to other institutions. A total of 1075 reagents were reused internally and 4382 items were donated for external institutions. As for financial data, between 2011 and 2018, the internal economy was US$16,700.70 and for external institutions it was US$62,633.11. When comparing the waste reuse according to the destination, an internal address showed a significant difference when compared with the external use. Some categories of reagents have greater added value and provide even greater benefits when reused. The strategy of capturing and making available expired reagents through the Chemical Waste Exchange is positive; it helps the management of the waste generated; the economic benefit will depend on the market value of the material; the adopted strategy avoids the need to remove raw material from nature for the production of new reagents and reduces the costs related to treatment and environmentally appropriate final destination.
