This thesis presents an innovative treatment technique for drilling cuttings, one of the most complex wastes of the oil industry. This waste is considered hazardous due to its high salt and hydrocarbons content and poses serious threats to the environment. The treatment process involves the incorporation of drilling cuttings to the clayey soil mass used for making bricks. It consists on applying high temperatures, over 8000C, to the clayey soil mass in order to obtain a solid, resistant and inert material. The results of the experimental programme have shown that this innovative process is technical safe and economical viable. As a result, Petrobras obtained an environmental license in the city of Mata de São João , State of Bahia, to produce in a large scale red bricks using drilling cuttings incorporated to the clayey soil mass.
