The utilization of nickel solid waste, such as carbon sulfur and dirty sulfur, has been provence to enhance the compressive strength of concrete. Vian Marantha Haryanto, a Young Expert Engineer at BRIN’s Research Center for Composites and Biomaterials, explained that testing at PT Vale Indonesia showed these two types of waste are not classified as hazardous (B3) waste. Research demonstrated that carbon sulfur, when used as a substitute for fine or coarse aggregates or as filler in concrete, can significantly increase strength, particularly after a 28-day curing period. This innovation opens opportunities for applications in bricks, paving blocks, road columns, and foundation.
In addition to adding value to industrial waste, this utilization also supports collaboration between MSMEs and local governments. This is especially important since nickel is a strategic mineral for the electric vehicle industry, with global demand projected to rise sharply to 6,265.74 metric tons by 2025. Using nickel waste in concrete is not only an environmentally friendly solution but also contributes to sustainable development and the green energy transition.
