Abstract
Increasing waste generation on construction sites has become a topic of environmental concern in the metropolis.
Most construction and demolition waste are not recycled but end up in landfills or dumps which occupy valuable
land. Landfills are costly and dumps particularly are unsightly and are sources of environmental hazards; hence
a study on waste management practice with a view to minimizing waste generation and encouraging recycling
becomes important. The study used questionnaires, 40 of which were fully filled and returned. The data obtained
were analyzed using average index. The study indicates that, demolition, renovation and material handling were
mostly implicated in waste generation, and that dumping and landfills are some of the current methods being
adopted in the disposal of construction waste within the state, industry best practice methods like recycling and
re-use are less frequently used just as open-air burning, and incineration are least often adopted. In conclusion,
the study recommends that site supervisors be educated on how waste due to materials handling should be
minimized, also that manufacturers of materials should have a basic standard for sizes of materials to prevent
cutting wastage. It also suggests that sanctions be introduced to discourage poor waste disposal practices and
encourage recycling
