The Inclusion of Palm Oil Ash Biomass Waste in Concrete: A Literature
About 90 million metric tonnes of biomass is produced in Malaysia annually [ 10 ]. This biomass residue consists of empty fruit bunch, fibre, shell, wet shell, palm kernel, fronds and trunks. Each oil palm tree fruit bunch produces about 21% palm oil, 6–7% palm kernel oil, 14–15% fibre, 6–7% shell and 23% empty fruit bunch [ 11 ].
