Abstract
Lagos is the largest producer of municipal solid waste in Nigeria, yet it is the smallest of Nigeria’s 36 states with the highest projected population, highest level of urbanization and it houses Nigeria’s largest chief port, and principal economic and cultural centres. Out of the total waste generated, only about 73 percent actually got to the final disposal site. There is a possibility of inefficient and ineffective municipal solid waste management system in place which can damage the ecosystem services, contaminate ground and surface water, creates greenhouse gas emissions, increase disease transmission, damages ecosystem services and discourages tourism and other businesses. To this end, this study analysed the efficiency and effectiveness of solid waste services and; the efficiency and effectiveness of solid waste services in Lagos State using primary data and conducting statistical tests. The study found a general agreement on what constitutes efficient and effective solid waste services. However, the study concluded that the waste management system in Lagos State is inefficient, ineffective and therefore; unsustainable. The study therefore recommends among others the urgent need to re-organize the waste management institutions for effective and efficient performance. This requiressubstantial planning ability, appropriate equipment and continuous managerial optimization of vehicles and workers productivity,efficient vehicle routing, better designed vehicles, managerial incentives, faster vehicle repairs, vehicle standardization.

The major tool of analysis here is the difference of two means.The difference of two means result for the incomes of Private Sector Participants (PSP) patrons and the cartpushers’ patrons produced a Zcalculated as indicated on the last column and the Zcritical at =0.02 is; 2.33
Inefficiency and ineffectivenessin municipal solid waste management system has the potential of damaging the ecosystem services, contaminate ground and surface water, creates greenhouse gas emissions, increase disease transmission, damages ecosystem services and discourages tourism and other businesses (Fenta, 2017)
This study conducted a study on the efficiency and effectiveness of solid waste services in Lagos state using primary data and conducting statistical tests
Summary
All Nigerian major cities like Abuja, Benin, Enugu, Ibadan, Kano, Kaduna, Lagos and Port-Harcourt are desirous of cost-effective and ecosystem-sustaining regime of municipal solid waste management because households in these States generate about a tonne of municipal waste annually and the trend is expected to skew upward in the future due to urbanization trends (Adeogba, 2000).Lagos is the largest producer of municipal solid waste in Nigeria as it generates an average of 7,500 metric tonnes minimum per day, yet it is the smallest of Nigeria’s 36 states with an area of 3,345 square kilometres (1292 sq. miles) which represents about 0.36 percent of Nigeria’s land mass of 923,768 sq. kilometres but with a population of 5,725,116 which was 6.4 percent of Nigeria’s population as at 1991. Lagos is the largest producer of municipal solid waste in Nigeria as it generates an average of 7,500 metric tonnes minimum per day, yet it is the smallest of Nigeria’s 36 states with an area of 3,345 square kilometres The population was projected to rise to 7,877,810 by the year 2002 (Nigerian State and Local Government Area Demographic Profile 1999-2010) It has a population density of 1712 per square kilometre based on the population census of 1991 (Population Census of the Federal Republic of Nigeria Analytical Report at the National level NPC 1991). It has a flat topography, a high water table, endemic perennial flooding and it is swampy (Adeogba, 2000).
