Rice chaff

As the cultivation of cotton in Japan is declining there is a shortage of cotton seeds on the market, but of.course a large amount of cotton is produced in the USA, India and China. At present, in place of the.cotton seeds many of the fireworkers use rice chaff for small or medium shells and Japanese cypress seeds for large shells. 

Cotton seeds are most popular as cores because the surface of the grain is downy so that it holds the composition very well. Rice chaff is also popularly used for smaller class shells. For larger shells seeds of Japanese cypress are used in mountainous districts and pieces of cork j are also used for the largest shells. In any case core material must be roughly spherical, must hold the composition well, and should not allow the fire to remain in it after the explosion and if possible it should be ultimately biologically degradable.

Straw, obtained after the removal of grain and chaff from the dry stalks of cereal plants, is an agricultural by-product. Straw has various applications such as fuel, animal feed, bedding for livestock like horses, packaging and decoration material, and constraction materials. About half of the yield of cereal crops such as barley, oats, rice, rye, and wheat is straw. Straws are the main agricultural waste materials and by-products of agricultural plants and are rich resources of biofibers. Its wide utilization in different fields draws the attention of researchers to make useful industrial products from such agriculture by-products [19-23].
