Waste management and disposal of industrial waste are an increasing environmental concern throughout the world and one of the most complex and challenging problems facing modern man. Indeed, the increasing quantity of waste generated due to human natural and industrial activities, of which some are toxic and hazardous, represents a serious threat to human beings as well as to the environment. Therefore recycling industry is becoming one of the most vital industries in our society for environmental protection and rational use of natural resources and the sustainability of raw materials to meet the needs of all industries, especially the booming construction and building one. In Kuwait, especially, where the natural resources are scares and depleting, building materials industry is faced with critical situation that could only be addressed through relying on imported raw materials or exploitation of recycled wastes such as recycled building rubbles and in industrial waste to compensate for the future shortages in the raw materials demands. This paper shed the light on one of practical methods for containment and applications of recycled hazardous industrial waste which has caused detrimental and agonizing environmental problem to The State of Kuwait since the 1990's, which have led to United Nations directive for enforcing environment health monitoring and the treatment of oil contaminated soils. In Kuwait, and since the oil fires, over 60 million cubic meters of sand is contaminated with oil, spread over various locations in the Kuwaiti desert. The main objective of this study is to test and qualify a containment system that consist of fly ash material with specific characteristics to be mixed in concrete form mixture with the contaminated sand and used as construction material for precast concrete elements or pavement road layers. Mechanical and performance tests carried out on building elements were satisfactory and have qualified this containment system as method of rehabilitation and application for industrial wastes.
