This paper studies the waste streams, hazardous and non-hazardous, generated by the shipbuilding and repair industry. A linear model is provided for the study which defines the raw materials and substances entering a ship-building facility as the Input, the activities and numerous building phases being carried out inside the facility as the Process, and the waste generated during the building or repair phases as the Output. The latter is the main issue of this study. Definition of the laws and regulations having jurisdiction over it, are given in a separate section for ease of reference. Suggestions for pollution prevention based on pilot studies and on-going research are discussed together with technological alternatives to reduce the waste stream flow, implement Best Management Practices, and offer a clearer view of the industry as a whole not only to the professional but also to the layman. The impact on the environment, though small in size on a per site basis, could become of concern if viewed cumulatively and over time. It is therefore suggested that the site manager, assisted by the environmental coordinator, look at present and future legislation, and include the required measures for compliance in the facility’s operational system. Though there will be up-front costs for personnel and extra man-hours as well as new management issues, the long run benefit will outweigh the concerns impacting on the “bottom line”. This paper provides also a literature seach (Hazardous Waste Bibliography) for waste management issues which can be useful to both the professional and the layman.
