System Dynamics Modeling for Waste Management from Convenience Stores
The GHGs may be emitted from incineration, recycling, composting, anaerobic digestion, and feeding pigs when managing wastes. Great amount of wastes generated in convenience stores are consisted of food waste, spent coffee ground (SCG), and municipal solid waste (MSW). Six different scenarios were established in this study. The GHG emissions from the scenarios were all mitigated except the 1st scenario. Incinerating food waste would greatly affect GHG emissions than incinerating SCG. The waste management with energy recovery would be helpful for GHG mitigation.
