Abstract
Technical and vocational skilled workmen provide essential services for smooth running of a society. The services add value to the economy and social status of the society. However, the operations of technical and vocational skilled workmen generate wastes that have negative impacts on the environment. There is a research need to determine measures of managing the wastes effectively. Therefore, this paper describes ways of enhancing waste management in technical and vocational jobs through information technology. Research data are derived from questionnaire survey. The questionnaire seeks opinions of 540 respondents on solid wastes that are generated from technical and vocational jobs and ways of improving solid waste management in technical and vocational jobs using informational technology. The data are analysed using the relative contribution index. The findings indicate that crumbs from auto mechanic workshops and scraps from computing, handsets and related materials repair workshops as well as metallic scraps from electrical and electronic technicians are solid wastes that have very high impacts on the environment. Enabling adequate repair of electronic gadgets and the promotion of the use of best practice for technical and vocational jobs are the most significant ways information technology enhance waste management in technical and vocational jobs. Also, promoting the use of machines for optimization of designs, and the application of technologies like LeftoverSwap, LeanPath, FoodStar and Love Food Hate Waste to lessen waste of food are other ways information technology enhances waste management in technical and vocational jobs.
