Understanding the Waste Sector Understanding the Waste Sector

Majority of Hamilton County’s solid waste goes to a Majority of Hamilton County’s solid waste goes to a managed landfill with a methane recovery system.managed landfill with a methane recovery system.

A significant portion of the methane (a GHG) is captured A significant portion of the methane (a GHG) is captured by the recovery system, rather than being released to by the recovery system, rather than being released to atmosphere. Methane is also stored in landfilled and atmosphere. Methane is also stored in landfilled and composted biomass. Therefore, the waste sector GHG composted biomass. Therefore, the waste sector GHG emissions are calculated as a net negative value. emissions are calculated as a net negative value.

Inventory only includes landfilled and composted waste Inventory only includes landfilled and composted waste streams. Recycling is not included in the Waste Sector streams. Recycling is not included in the Waste Sector Baseline Inventory (not a life cycle inventory).Baseline Inventory (not a life cycle inventory).
