Solid waste management has emerged as one of the greatest challenges facing environmentalprotection agencies and the communities in developing countries and the increasing waste generation has become a topic of water pollution and environmental concern in the metropolis.This study seeks to evaluate the management of solid waste in Lagos State and proffers workable solutions to these challenges which will improve environmental sustainability.In this study, solid waste management challenges are characterized by inefficient collection methods, insufficient coverage of the collection system and some level of improper waste disposal. Observation of the environment, and direct interviews with people in the area was also conducted. The data obtained were analyzed and the study indicates that wastes generation, sorting, handling and disposal were mostly implicated, and that dumping and landfill are some of the current methods being adopted in the disposal of wastes within Lagos, composting and incineration are less often adopted just as industry best practice methods like recycling and re-use are less frequently used. It was also seen that the main type of waste disposal system used in Ajah is the PSP, which is meant to make waste management better, but due to challenges in pick up times, it seems to have a drawback. The analysis shows us that the use of PSP is the most prominent waste disposal system practiced but with a challenge of pick up timing. The most generated type of waste within the study area happens to be the food waste. To this effect, recommendations were given to bring solutions as follows;People should be treated as active partners in the process of change, there will be a more likely successful situation of waste management; Relevant information should be presented to the people and even with an increase of awareness to a certain level, additional monitoring and sustained management over a long period of time is necessary; The monthly environmental sanitation practice should be taken more seriously and the waste collection trucks from LAWMA should immediately after the sanitation if not during the sanitation, go round to collect the refuse that will be heaped on roads during the sanitation practice; The state assembly should formulate laws on waste management which will go as far as individual waste practice and ensure that the laws are enforced by government agencies; Monthly awards to neatest areas should be instituted to encourage the people of the areas to keep their environment clean always by properly handling and storing their wastes. Government should not only make laws, but sponsor public health and environmental education programmes regularly and also make environmental education part of the education curriculum at all school levels.
