Conversion of Dye Soaked Dry Flower Industrial Waste into A Value Added Product Using Earthworm

By adopting Vermi technology the dye soaked and chemically treated hard natured dry flower industrial waste, which became a major problem to the industrialists and one of the public nuisance to the people of Thoothukudi was converted into a value based bio-product, the vermin compost to some extent. This study was only a pioneer and hence a further improvement in the technology may improve this process a more successful one. In this experiment the hard mega sized dry flower industrial waste were pulverized into small pieces and mixed with cow dung in the ratio of 1:1 and 2:1 and earthworms were allowed to act on them. A separate control was maintained using cow dung and leaf litter. The process of vermi compost completed in the control on 80th day while in the treated, the process was preceded beyond 120days. The net compost obtained in control was 98.8% and in treated it was 85.7 and 62.08 in 1:1 and 2:1 ratio. The biochemical analysis also showed a remarkable alterations such as reduction of S, H and C/N ratio which are at the acceptable level by the plants.
