Dear Ganeshan,
Though following judgment pertains to C.E. but you can use it as reference in VAT matters also to get the relief.
Inputs used in effluent treatment plant are eligible for CENVAT credit : - In Indian Farmers Fertilisers Coop Ltd. v CCE 1996 (7) TMI 141 - SUPREME COURT OF INDIA =86 ELT 177 (SC) =AIR 1996 SC 2542 = 1996 (5) SCC 488 = 15 RLT 498, it has been held that treatment of effluents is an essential and intergral part of the process of manufacture of plant. The apparatus used for such treatment of effluents in a plant manufacturing a particular end-product is part and parcel of the manufacturing process. Hence, inputs used in the effluent treatment plant will be treated as 'used in the manufacture'. It was also held that inputs used indirectly in the manufacture will also be in the manufacture. It is not essential that ot qualify itself as raw material, it had necessarily and in all cases to go into and be found in the end-product.
Chemicals used in effluent treatment plant is input for CENVAT credit - CCE v Madras Aluminium 2008 (1) TMI 198 - HIGH COURT MADRAS= (2008) 226 ELT 342 (Mad HC DB).
