• #3: Reduce Food Waste – 70.53 Gigatons avoided, if 50% global food waste

reduced by 2050

• #55 Household Recycling – 2.77 Gigatons avoided if average global recycling

rates at 65% by 2050

• #68 Waste to Energy – 1.1 Gigatons avoided if 62.6 GW of WTE facilities

installed globally by 2050.

Medicine Disposal

2015-2035 Contract Extension • No new reliable disposal options • Strong desire to keep plant dedicated to

our community’s waste (rather than have merchant plant)

• Financial pressures – low electric rates & extremely low landfill disposal pricing

• WTE Facility capital improvement projects required funding for long term reliability

Agreement on Capital Refurbishment Projects

• Negotiated list of projects (“Tier 1 Projects”) • OCRRA established $15 million fund • Tier 1 Projects to be completed in 3 years • Covanta pays 5% yr 1, 10% yr 2, 15% yr 3 • After $15 million fund is depleted,

additional projects must be at least $1 million and Covanta pays at least 50%
