The prime condition of providing sustainable urban development is realisation of sustainable industrial activities. The observation today, especially for the developing countries is that the main effort is for the economic development and the structuring of industrial activities within the concept of sustainability is unfortunately a seriously neglected subject. Within this context, in this paper a study shall be submitted on the sustainability concept for the industrial settlement of Dilovasi, which takes place nearby Istanbul, the most industrialised region of Turkey. After presenting the existing situation of industrial activities, a set of suggestions shall be developed for the spatial organisation of sustainable industrial activities in Dilovasi settlement.
