Mechanical Biological Treatment of Residual Waste – Lessons from Europe 1. Capital costs and tipping fees can be high 2. Material recovery rates are low 3. Compost quality is poor 4. Diversion rates are 20% without energy recovery 4

Mechanical Biological Treatment of Residual Waste – Lessons from Europe • Developed to meet landfill treatment and stabilization requirements • 570 active MBT facilities in 2017 • 55 million tons per year • Another 120 facilities by 2025. 5

Tipping Fees in UK • Average - $95 per ton • Range - $78 - $101 per ton. Frog Island MBT Facility (London) 11

Material Recovery Rates Are Low • Metals Recovery Rate – 3% New Earth Canford MBT Facility (Dorset, ENG) 12

Compost Quality is Poor 13

Diversion Rates 14

Diversion Rates Mass Balance of MBT Facilities in Germany in 2007 % Diversion Tons Residual Rate Waste 22 Metals Recovered 0, 000 3% 3% Solid Recovered Fuel 4, 07 (SRF) 0, 000 58% Biologically Treated 1, 54 Residues 0, 000 22% Moisture 1, 21 Loss/Fermentation 0, 000 17% 7, 040, Tons Processed 100% 20% 000 15

Reality Check • Residue Stream = 30% of MSW • MBT Diversion Rate = 20% of RS = 20% x 30% = 6%. 16

Mechanical Biological Treatment of Residual Waste – Lessons from Europe 1. Capital costs and tipping fees can be high 2. Material recovery rates are low 3. Compost quality is poor 4. Diversion rates are 20% without energy recovery 17
