PAPER FROM STEM OF COTTON PLANTS
The stem of the cotton plant is rich in cellulose, a good material for papermaking. This process came from the Cotton Technological Research Laboratory in Bombay, India which taught papermaking from cotton plant stems – such as writing paper, wrapping paper, and newsprint. They used soft green stems with 70% moisture.
- Boil the chopped stem in 6% alkaline.
- Wash the cooked material and place in a beater to separate the fibers.
The resulting product is a good quality yellow pulp.
(In general, paper is made from cellulose materials. The procedure is almost the same except maybe for the ingredients used.)
PAPER FROM BANANA STALK
Researchers from Japan National Chemical Laboratory for Industries discovered how to make paper using sugarcane bagasse and banana stalk. No poisonous chemical is used unlike the commonly used sodium suphide, sodium hydroxide and chloride. Such method is expensive and pollutes the environment. In the newly discovered method, no bleaching is needed. The chemicals used can be reused. Because of very minimal capital, this could be a good small industry.
