Paper from Rice Straw

Paper can be made from any fibrous plant but the best material is rice straw. Abundant rice

straw go to waste during harvesting time. With a very minimal capital, this agricultural waste

could be a good source of livelihood. Making paper from rice straw can be done even by

children in their homes or as a project in the community. The art of papermaking is being done

since the ancient times in China and Japan where different types of paper such as glossy and

silky ones are produced.

Most of our users are clogged with water lilies or hyacinths. These fast growing plants are

hazardous to sea travels. They also cause skin allergies. However, the Technology and

Livelihood Research Center (TLRC) found that water lilies could be a good substitute for

leather in shoes and bag making.

There is at present leather and other raw materials shortage for shoes and bag making. Only

75% of the industry needs are supplied, therefore water lilies could supplement the needed

materials.
