Cardboard production in Indonesia continues to rise, contributing 13.2% of national waste, with only 48% recycled. Meanwhile, cement production drives limestone mining and CO2 emissions. This study explores an eco-friendly cement alternative made from cardboard waste. The process involved soaking, crushing, pressing, and drying cardboard into powder, then mixing it with limestone and sand. Simple experiments were conducted to examine its basic characteristics. Results showed the material could withstand light pressure and water exposure, indicating
potential use in lightweight construction. This innovation reduces cardboard waste, decreases reliance on conventional cement, and supports sustainability, circular economy, and green business initiatives.
