10 3 Technology BEKON process generates revenues from gate fees, power / gas production, heat and compost 1 ton of waste BEKON process Revenue per t of waste Gate fee Organic fraction of municipal solid waste (MSW) kwh Electricity + or Green waste 230 kwh heat for heating/cooling + 50 L Diesel equivalent Source segregated biowaste or food waste 400 kg compost (quality depending on input) 10

11 3 Technology Simple and robust process requires no extensive pre-treatment Process scheme 11

12 3 Technology Fermenters and compost tunnels are made of concrete View on fermenter View on compost tunnel 12

13 3 Technology 5-step process transforms waste into energy and compost Biowaste is dropped in storage area Fermenter is filled for anaerobic digestion. Material sits for 3 to 4 weeks. Digestate is put into compost tunnels Compost is moved to maturation area Compost is screened 13

14 3 Technology State-of-the-art process logic and control ensure >99% operational availability 5 key advantages of BEKON technology explained + Robust and simple process Contraries (plastics, stones, sand, batteries etc.) have no negative effects on gas production + Remote supervision by BEKON improves plant performance + Lack of moving parts and batch operation ensures simple handling and >99% operational availability + Thermophilic process guarantees high plant profitability and pathogen destruction X + High safety and emission standards 14
