ABSTRACT
Seafood processing industries, in general, consume large quantities of water during processing activities and generate the wastewater with high organic and nutrient loads which ultimately becomes a source of methane (CH4) and nitrous oxide (N2O) emissions. Intergovernmental Panel on Climate Change (IPCC) guidelines for national GHG inventories1 have illustrated the methods for calculation of CH4 and N2O emissions from the wastewater based on degradable organic matter and nitrogen components respectively. One of the seafood processing industries located in Samut Sakhon province, Bangkok was selected as a case study with average production capacity of 35-38 tons per day. The main objective of this study was to recommend a practical method for reducing GHG emissions by collecting methane from anaerobic process. Furthermore, methane utilization scenarios such as flaring and steam generation are also suggested. Reduction in GHG emissions for each scenario is also estimated.
