This study has conducted greenhouse gas emission reduction test as using Oyster-shells originated PCC paper filler compare to non-Oyster shells used PCC. This examination was estimated and calculated in accordance with both IPCC (Intergovernmental Panel on Climate Change) and World Business Council for Sustainable Development (WBSCD). The greenhouse gas emission reduction estimation result indicates that, when oyster shells are recycled and used as paper filler, it reduces 27.97 tCO2 per 100 ton of oyster shells. It is greenhouse gas emission 44.27 tCO2 from PCC production changed to carbon emission reduction when replaced with oyster shell. LNG greenhouse gas emission 16.3 tCO2 in relation to the pre-treatment with oyster shell per 100 ton is also reflected. As a result, it is assumed that roughly 0.2797 tCO2/oyster shell·ton.
