Life cycle assessment of palm oil clinker as a binder and aggregate replacement in concrete
Palm oil clinker (POC) is a by-product derived from crude palm oil (CPO) production. Many studies have examined POC in concrete and it has often been stated as being environmentally sustainable. However, evidence to support these claims are not abundant in the literature. Therefore, this study aimed...

Palm oil clinker (POC) is a by-product derived from crude palm oil (CPO) production. Many studies have examined POC in concrete and it has often been stated as being environmentally sustainable.

Therefore, this study aimed to assess the environmental impact of POC using a comparative, midpoints life cycle assessment approach based on 13 impact categories from ReCiPe2016. The use of POC as a binder replacement, fine aggregate and coarse aggregate was considered. Only production of cement, sand, gravel, POC and transportation were included in the system boundary.
