Alternate fuel and raw material (AFR) recovery from hazardous industrial waste
has gained popularity in recent past. The recovery not only facilitates waste minimization, but
also reduces incineration burden. The present study involves the investigation on
characteristics, quantity, existing disposal pathway for various wastes generated from
SIPCOT, Cuddalore. Investigation reveals that the majority of the waste generated from the
industrial estates including wastewater disposed or stored unscientifically, causing health and
environmental catastrophe. The local industries majorly generate wastes of corrosive nature
and is of no contribution from recovery/recycling perspective. Only three industries identified
as Pioneer Miyagi Chemicals, SPIC Pharmaceuticals Division, and Loyal Super Fabrics
Limited produce wastes of higher calorific value (CV) such as spent solvents, discarded
medicines, and damaged fabrics respectively. The crucial characteristics such as heating
value, moisture content, ash content, and chloride & sulphate content were analysed and
observed as 4787, 4528, and 2528 cal/gm; 6.5%, 3.8%, 5%; 3.4%, 6%, 12.5%; 0.8%, 3.2%,
0.4%; 1.2%, 4.7%, 0.8% respectively in above sequence. Damaged fabrics were shredded and
mixed with discarded medicines in 1:1 ratio to compensate the excessive chloride and
sulphate content, whereas spent solvent was solely well enough to be utilized as AFR. The
mixed AFR sample (M1) had a CV of 3476 cal/gm with chloride and sulphate content of
1.7% and 2.53% respectively. Thus the present study suggests to develop an alternate waste
disposal pathway for the above industries by collaborating with local cement industries and
facilitate revenue recovery.
