Abstract

The purpose of the study was to determine the rates and patterns of motor vehicle engine waste oil generation in Nairobi area and audit the existing waste oil management strategies with a view to recommending environmentally sound management alternatives. The study area was clustered into 8 Divisions for the units that were selected for the study. Institutions, which included Multinational Oil Companies, National Environment Management Authority, Petroleum Institute of East Africa, Waste Oil Disposers and garages, were interviewed. Oral interviews were conducted and the findings were recorded in the respective Questionnaires. Some selected waste oil generating units (garages) were monitored for 90 consecutive days for their daily generation rates and the findings were recorded in the Observation Record Sheets. This was to help in determination of the actual generation rates. The overall daily mean generation rate for each unit in Nairobi was found to be 12.6 litres per day. The annual total amount generated in Nairobi was found to be 27.3 million litres. The general trend in the average daily generation rates of waste oil generation among the classes was Jua Kali with the highest rate, followed by institutionals, Multinationals and Independents in that order. It was found that there was lack of an appropriate regulatory intervention specific to waste oils in Kenya. The law that would otherwise address the problem of waste oil in the environment had the standards for waste oil provided for under it at their development stages. There was lack of commitment on the part of the government to control waste oil and the lack of capacity to effectively address the problem of waste oil in the environment at the government institutions concerned with environmental matters. The study gives data that can be used to inform policy and development of strategies for waste oil management in Nairobi. In recommendation, waste oil generators should keep records for the amount generated and their licensing should be streamlined. The government should commit itself to the implementation of appropriate laws for waste oil management and provide the capacity required by the regulatory institutions for effective and efficient implementation of the laws. Studies in Environmental Risk Assessment and Life Cycle Assessment for waste oils, and quantification of waste oil polluted soils and their remediation costs should be carried out in future.
