摘要:In the past few decades, widespread adoption of green revolution technologies in agricultural practices has increased the crop yield. But this intensive mechanization of agriculture is generating wastes from the irrational applications like wastes produced from rice and wheat harvesting constitute about 81-90% residues as rice and wheat husk. These crop residuesare considered as waste but in actual these are natural and valuable resources reflected as potential black gold. However the management of these residuesis a great challenge and the forgoing disposal method of burning the husks has contributed adversely to the environment and causes greenhouse effect. In the present study we proposed a treatment method for rice and wheat crop residues which has no drawbacks as processing of rice and wheat husk for the potential utilization of the material for pottery products. Some physical properties were also measured both of husk paste and pots these include dry shrinkage rate, moisture content, porosity rate, plasticity, color comparison, drying time, absorption rate, wall strength and biodegradation rate. These properties were measured to assess the quality of product and to establish which husk material is more suitable for pottery. Wall strength of different samples was found out by Vickers hardness test which were in the range of 26.5-33.87HV and the values of biodegradation rate ranged from 15-33days. Due to excellent binding ability and appropriate wall strength both the rice and wheat husk material are applicable to form pots. They took very less time and biodegrade easily reducing pollution effects, loads on disposal sites and preserving the non-renewable petroleum resources.
