Review and assessment of mechanic village potentials for small scale used engine oil recycling business

Abstract

Mechanic village should be adapted in developing countries rather than the city-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 in excessive trace metal pollution of topsoil and insecurity 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 turnover in excess of $2,234,375.00.

Used Oil Storage and Disposal Practices in Automobile Repair Garages in Ghana

“…In addition, tiny pieces of metal from engine wear and tear, such as lead, zinc and arsenic, make their way into lubricants, further contributing to the polluting potential of used motor oil. Because used motor oil is heavy and sticky, and contains an extensive concentrated cocktail of toxic compounds, it can build up and persist in the environment for years [3][4][5]. Indeed, a paper presented by Nwachukwu et al (2012) shows the environmental impact assessment of used engine oil (table 1).…”

Indeed, a paper presented by Nwachukwu et al (2012) shows the environmental impact assessment of used engine oil (table 1). To help address the problem of used oil pollutions in the environment, laws, regulations and standards on proper storage and disposal of used oils are enacted and enforced in most developed and developing countries to ensure that vehicle repair garages in these countries properly store and reasonably dispose off their generated waste oils.…”

A Review of Methods for Removal of Contaminants in Used Lubricating Oil

“…They all used the clay as an adsorbent to remove the odour and dark colour. What makes acid-clay method unique from others are; with its simple method, affordable capital investment, low operating cost and does not need skilled operators [17][18][19].…”

Experimental assessment of regenerated lube oil in spark-ignition engine for sustainable environment

“…Deteriorated oil is more poisonous, toxic and harmful than nondeteriorated oil. Generally, used oil is incinerated and dumped into landfills which may have serious impact over environmental conditions 7 because of hydrocarbons, heavy metals, polychlorinated biphenyls (PCBs) and other halogen compounds. 8 In order to counter such threat, waste lube oil is regenerated to turn it to usable product so that the quantity of lube oil being disposed off improperly can be lowered.…”
