Characterization of cassava stem and its potential as laminated product / Norhayati Hamzah

The lack of wood supply and higher demand for wood product has encouraged the researchers to find alternative materials for wood composite industry. Cassava (Manihot esculenta) stem from agricultural waste is a potential alternative to become a value- added product. The cassava stem was regarde...
