Abstract: The seafood industry is the major food industry in Thailand. The common environmental problems of this industry are high water consumption and generation of large quantities of solid wastes. The water consumption was measured in canned tuna (pet food) process and canned squid process by two methods. The lSt method, the whole processing areas of each process were classified into 4 sections. The water consumption in each step was measured by section. The 2nd method, the water consumption in each stepthrough the whole process was measured in the same day. The canned tuna (pet food) process consumed water 12.5 (the 1" method), 13.0 (the 2nd method) m3/ton. The major portions of water consumption were consumed in spray cooling process and equipmentand floor washing process. The canned squid process consumed water 23.7 (the 1" method during high season period), 33.9 (the 2nd method during low season period), 20.8 (the 2nd method during high season period) m3/ton. The major portion of water consumption wasconsumed in equipment and floor washing process. The highest pollution load of wastewater characteristics in canned (pet food) process and canned squid process were found in precooking process. The alternate options of water conservation were selected and experimented in theprocesses. For canned tuna (pet food) process, the options were 1) installed pressure spraying nozzles at spray cooling process, 2) reduced 45 degrees to open water valve, used hot water and released every 4 hours for can washing (after seaming) process and 3) educated plant personnel on water conservation for equipment and floor washing process. It was found that net annual saving costs were 78,572, 13,046 and 15,701 bathtyear or18.3,3.0 and 3.7 bahtlton of raw material and the water consumption was reduced by 65.9, 55.6 and 14.2%, respectively. For canned squid process, the options were 1) improved procedure of cleaning process and 2) educated plant personnel on water conservation for equipment and floor washing process. Net annual saving costs were 3,489 and 7,686 bathlyear or 3.3 and 7.3 bahtlton of raw material and the water consumption was reducedby 39.3 and 17.9%, respectivejy. The solid waste generated in the canned tuna (pet food) process was 37.2% of raw material while the solid waste from canned squid was 15.9% of raw material. The highest composition'in all kinds of solid wastes from both processes was protein, except bone andtail from canned tuna (pet food) process which the highest composition was ash. These solid wastes were sold at low price. Therefore, the alternate options of effective use of these wastes were recommended.
