摘要：Mechanic village should be adapted in developing countries rather than thecity-wide auto mechanic workshop practice. This is suggested because developing countries are yet to enforce environmentally friendly automobile workshops and mechanic practice. If all automobile repair works in different cities are confined to mechanic villages, collection, preservation, recycling and reuse of spent oil will become effective. The goal is to stop the habit of disposing spent automobile oil on the ground, which results inexcessive trace metal pollution of topsoil andinsecurity of food products in the affected areas.Beside environmental quality, business and employment opportunities will improve.Small-scale refining or reprocessing of used oil in mechanic villages is lucrative and recycling plants are affordable and available. Cost benefit analysis indicate strong environmental benefits and annual turnoverin excess of $2,234,375.00.
