Various waste streams are growing in volume and complexity as the economies of developing countries expand. To this end, the control of the environmental impacts associated with construction waste is of increasing concern. While the implementation of environmental management has a direct contribution to environmental protection, it involves the allocation and investment of resources, thus presenting a profit-making challenge, particularly to contractors in the construction industry. This paper investigates construction waste in the Francistown area of Botswana as a case study. The study considers waste from typical construction sites in the Francistown area, which includes sand, cement, concrete stone, concrete, steel, timber and general debris. The data was gathered from a survey and interviews with project managers, contractors, site workers and waste management service providers. The survey shows that construction sites generate large amounts of materials waste. Poor waste management leads to direct financial losses, poses a danger to the environment, and hampers the national waste management efforts of Botswana. Opportunities are identified to reduce material waste in the developing country context through the adoption of effective materials control and waste management procedures on site.
