Particle Board from Cotton Stalk

Particle Board from Cotton Stalk

Description and salient Technical features

Cotton plant stalk is a renewable agrowatse material, available to the extent of about 30 million tonnes annually in our country. At present it is not being used for any commercial purposes, except as fuel by the rural masses, while the bulk of the stalk is disposed off by burning in the field itself. Technology was developed for preparation of particle boards from cotton stalks.

The process involves chipping of cotton stalks, rechipping, sieving to separate the particles, mixing with binder and catalyst, mat formation, followed by pressing in a hot hydraulic press to get the boards. Good quality particle boards could be prepared using this raw material and these boards were found to have properties on par with boards prepared from forest and other agricultural residues.

Performance Results

Use of cotton stalks as a raw material for particle board industry would fetch an additional income of about 5% to the cotton farmers. Also this would have a positive impact on environment reducing the use of wood for particle board manufacture and thereby contributing significantly to the slowing down of the deforestation process. The boards prepared from cotton stalks have properties conforming to BIS standards. These boards were found suitable for preparation of furniture items using modern machines. The quality of furniture was very well accepted in the market. The boards find applications in furniture making, partitioning, paneling, false ceiling, etc.

Cost: For ten tonne per day capacity plant, the total project cost is 580 lakh (Approximate)

How the new technology will impact the income of the farmers / end users:

Main beneficiaries will thus be the cotton farmers who will get additional income from the sale of cotton stalks. Avenue for rural industries and employment generation.

Social/environmental/other benefits:

Additional income to farmers, a new raw material for composite board industry, avenues for setting up of rural industry, employment opportunities for rural youth, conservation of forest resources etc.
