UMPSA researcher Associate Professor Ir. Dr. Chin Siew Choo produces Brewcrete, eco-friendly sustainable cement from coffee waste

PEKAN, 18 August 2025 – Looking at coffee waste, the by-product of the brewing process increasingly produced by Malaysians who drink an average of 2.38 cups of coffee a day (totalling around 3 billion cups daily) and generating about 100 tonnes of coffee waste per day, a team of researchers from Universiti Malaysia Pahang Al-Sultan Abdullah (UMPSA) led by lecturer from the Faculty of Civil Engineering Technology (FTKA), Associate Professor Ir. Dr. Chin Siew Choo, has produced Brewcrete.

This research project examines the use of coffee waste as an additive in concrete cement.

The research, which began in 2020, was the final year project of two FTKA students, Khong Sheh Ching and Yee Jia Jun, who are now postgraduate students.
