INTRODUCTION

Industrial waste from manufacturing comprises of wide range of different processes, such as sludges, product residues, kiln dust, slags, and ashes. In Malaysia, majority of industrial waste or scheduled waste come from oily sludge.Oily sludge is a huge amount of solid waste produced in the petroleum andpetrochemical industry, which has high resource recycling value. With the rapid development of society, the public's awareness of environmental protection has gradually increased. At present, the treatment methods of oily sludge mainly include incineration, solidification, solvent extraction, pyrolysis, and membrane separation. Oil sludge pyrolysis converts oil sludge feedstock to macromolecular organics into gaseous and liquid products with smaller molecules by heating using an anaerobic environment to realize the energy recovery and utilization of energy. The main product of oil sludge pyrolysis includes solid residues, condensable liquid oils, and non-condensable gases. The course also discusses the optimal operating conditions and expect product yield from oil sludge pyrolysis and desired products. Beside energy recovery from oil sludge treatment, the residues may be pelletized as biochar pellets, the new development for adsorbent material or fertilizer. The price of biochar is RM11486.16 per ton. Biochar, the transformation waste to valuables,  be generated around 30% from tonnes of oily sludge waste which is 30% of 1000 million tonnes a year of sludge and oily sludge is equivalent to 300 million tonnes of Biochar production. The course will cover history development of biochar, technique of production, chemical and physical characteristics, parameter of properties and applications.
