B3 waste management through Rotary Kiln type incineration technology in construction activities in EPC projects

Rekind (Industrial engineering) engaged in construction on EPC (Engineering, Procurement, Construction) projects are activities ranging from civil and structural work, tank fabrication, piping work, electricity and instrument etc. From the work of each of these disciplines there are activities that require welding, sand blasting, painting and liquids to clean the outer rust (pickling), Majun that has been used, chemical liquids for internal cleaning of installed pipes, used lubricants. In this EPC, work causes waste, which cannot be allowed. In addition, if the company does not realize that the waste produced is simply thrown into the liquefaction system without any processing process. It will have a negative impact on the environment and human life. Given the magnitude of the risks and their impacts, efforts to manage B3 waste on construction activities are directly under the responsibility of the construction manager of PT Rekind and are coordinated by the HSE (Health, Safety, Environment). For this reason, we should know how to manage B3 waste in EPC activities at PT. Rekind through incinerator technology. So the study method carried out is an engineering research method or the method of management activities through the Type Rotary Kiln incinerator technology, where the management of B3 waste materials from the activity begins to mark the place where the B3 storage produces for a maximum of 90 days and transportation to treatment from the storage of B3 Waste. Rotary Kiln type incinerator technology is a two-stroke combustion process with various types of B3 waste materials, the first Combustion Chamber is for waste and the second Combustion Chamber is for the remnants of rudimentary gases burning in the Primary Chamber and lower temperatures are often needed to prevent the slagging of certain waste materials. The ash produced during the combustion process is discharged through the bottom of the second combustion chamber. So that the purpose of this study is to produce new material in the form of ash, which can be reused into fertilizer and others.
