Abstract:
Construction waste in general consists of both waste generated by construction as well as demolition.
Disposal of demolition waste is becoming a growing problem which became evident after the Indian
Ocean Tsunami in 2004, particularly in Sri Lanka. Management of these wastes came into picture with
the establishment of a C&D waste recycling plant by the Construction Waste Management (COWAM)
Project. With the development of construction industry, the question arises whether COWAM plant
alone is capable of managing such waste. Thus, this paper presents recommendations to further
improve the COWAM plant by expanding the same into other local areas. COWAM plant was selected
as a single case study and data were gathered through semi-structured interviews. It revealed lack of
funds to establish recycling plants and infrastructure and unavailability of a proper C&D waste
management policy in Sri Lanka as major problems. Taking contracts to demolish buildings and
increasing the number of productions are the most important recommendations to improve the
COWAM plant. Further, allocation of requisite budget for infrastructure and public awareness is
recommended to enhance the COWAM concept in Sri Lanka.
