Abstract: The current era of industrialization has become a severe problem regarding the handling of waste, which causes a threat to the environment. From a benefits standpoint, all waste can be processed and utilized to provide value and economic benefits. RCS moulds in the foundry industry cannot be used repeatedly, so their use is limited and tends to produce waste that cannot be reused as moulds, thus potentially polluting the environment. This type of sand used as moulding sand with a binder has been widely studied, with research results affecting the permeability and strength values against compressive-shear loads. This research aims to determine the effect of adding RCS to greensand sand on the characteristics of moulding sand. Variations in the use of RCS in this study were 0%, 20% and 20% in the greensand mixture, with five test objects for each variation. In this study, three tests were carried out: Permeability, shear testing and compression testing. The results of this study indicate that the more addition of RCS, the lower the permeability value. Whereas the results of the compression and shear tests have the same tendency, with the results of adding RCS up to 20%, it will increase compared to without adding RCS and then with an addition of 40%, it will decrease.
