To check environment pollution,the Haryana State Pollution Control Board has directed all rice shelling units to follow norms pertaining to proper handling,storage and transportation of rice husk ash,or face the music.
According to the guidelines issued by the Board,the rice shellers have been directed to ensure adequate dust extraction from various points of dust generation from unloading to paddy cleaning. As dust particles extracted from paddy are very fine in size,the extracted dust will be filtered through a bag filter-type control device. A low cost bag filter,made of cotton bags with a manual shaker-type cleaning arrangement,could be installed. The filtered fine dust will be collected and sealed in bags and then disposed along with the bag,so that the fine dust does not get airborne again, the guidelines stated.
Units will also be required to provide a closed room for blowing and storage of rice husk. Such activity will not be allowed to take place outside the premises. The rice bran generated during polishing of raw rice,which is fine in size and can get airborne with wind,will be stored in closed sheds only.
