Abstract

The extreme rise in environmental challenges owing to agricultural activities, among which paddy
stubble burning remains a huge concern. Burning about 15 million tons of paddy stubble leads to
emissions discharge of various toxic pollutants and gases notably, nitrogen oxides, methane and carbon
monoxide in large scale causing global air pollution and climate change. The study focuses on
obtaining and preparing a paddy stubble powder and using it with glass fibers and epoxy resin to make
composite materials. The composites were prepared by the hand layup method and later their
mechanical and metallurgical properties were studied through hardness tests, compression tests,
microstructural assessments and water absorption tests. These biodegradable composite materials can
be made from utilization of agricultural waste, reduction of environmental pollution through stubble
burning and the provision of a substitute for conventional composite materials. The study implies the
composite materials which are biodegradable are suitable for industrial purposes without posing
environmental challenges there by supporting global efforts toward sustainability. Future directions
for research include refining the composite mixtures and seeking other applications so as to improve
the performance and environmental footprint of these materials.
