Study of selected bamboo species on the enhancement of recycled paper properties / Nur Musfirah Suhaimi

Recycled paper is already used as a replacement for pulp and paper raw material as away to minimize emissions of greenhouse gases that contribute to climate change. Homification of recycled paper has decreased its conformability and inter fiber bonding capacity. The effect of the bamboo fiber (Aur,...
