Check pollution level in sugar mills, say experts

EMINENT SUGAR technologists stressed the need for checking pollution level in the sugar industries in the State and urged them to utilise the waste for power generation.

They expressed their views on the third day of the refresher course being organised at the National Sugar Institute here on Wednesday.

Dr PK Agarwal gave nine suggestions for reducing the volume of pollution. He said there should be no floor washing in the mills and the bagasse which was used for sweeping the floor should be sent to the cane carrier or be burnt in the boilers. Factory owners should adopt cleaning with dry bagasse instead of washing with water. However, he advised the mills to sweep the floors at least once a day by sprinkling water.

He further said that polluted drains should be segregated from the drains carrying cooling water and provided a grit chamber to arrest the press-mud going into the drain.

Dr Agarwal said, “Do not allow juice, syrup sugar or molasses to trickle from pipes, valves, flanges.” Similarly, care should be taken to ensure that the overflowed material did not get mixed with the effluents. He said precautions should be taken to check the leaking of the oil and grease on the floor or in the drain. It should not be allowed to mix with the effluents, he added. The spray pond water should be kept protected against the merry makers, he suggested.

Instead of throwing bagasse, the sugar scientists should use it for generating power, he said adding that in several sugar factories the bagasse was being used for generating power and even some sugar mills selling excess power to the State Electricity Boards.

He said that there were possibilities of producing mineral water through bagasse but the project was at the very initial stage. He said experiments in this sphere were being carried out at several sugar factories but the commercial viability of the project was yet to be ascertained, he added.

Among other who delivered their lectures included HN Gupta, A Krishna, SP Tripathi, GD Agarwal and Shri Tippuswamy. While Krishan spoke about the utilization of the bio products in the sugar industry, SP Tripathi highlighted the technological advancements made by the sugar industry to boost the quality production of sugar acceptable in the global market.
