Understanding the Waste Sector Majority of Hamilton County’s solid waste goes to a managed landfill with a methane recovery system. Majority of Hamilton County’s solid waste goes to a managed landfill with a methane recovery system. A significant portion of the methane (a GHG) is captured by the recovery system, rather than being released to atmosphere. Methane is also stored in landfilled and composted biomass. Therefore, the waste sector GHG emissions are calculated as a net negative value. A significant portion of the methane (a GHG) is captured by the recovery system, rather than being released to atmosphere. Methane is also stored in landfilled and composted biomass. Therefore, the waste sector GHG emissions are calculated as a net negative value. Inventory only includes landfilled and composted waste streams. Recycling is not included in the Waste Sector Baseline Inventory (not a life cycle inventory). Inventory only includes landfilled and composted waste streams.

Looking Ahead Reductions in GHGs will result from developing plans to address opportunities such as: Curbing energy usage within buildings Curbing energy usage within buildings Promoting alternative fuel vehicles and use of public transportation Promoting alternative fuel vehicles and use of public transportation Increasing green space Increasing green space Increasing recycling and composting programs Increasing recycling and composting programs
