1 The Incinerator Ash Company Optimisation of bottom ash treatment Rogier van de Weijer Business Development Director

2 Goals of recycling bottom ash Convert ash into valuable raw materials 1. Recovery of (non ferrous) metals down to 0,5 mm 2. Reuse ash minerals in alternative markets (NL Greendeal - non IBC) 3. Decrease carbon footprint for WtE facilities Technical challenges: Wet de-slagging at WtE facility This makes the ash stick together tightly Embedded fine NF particles are hidden in clogged minerals Separating heavy / light non ferro s: Conventional sink-float operations are not build for particle sizes < 10 mm Practical knowledge and experience (how does theory work out in practice?) Discharge of ash residue that is qualified as waste (EURAL Code ) Financial challenges: Optimise the balance between costs(capex and OPEX) and revenues related with bottom ash recycling Make use of low cost technologies and create the highest possible value from recovered materials

3 Strong foundation Inashco BV is a 100% Fondelcompany. Valorization of DUT technology Continuous R&D at DUT laboratory (CiTG)

5 Company characteristics Inashco characteristics: Installed base of 9 BA processing installations and 5 installations under construction Installed base of 2 Central Upgrade Facilities to further separate non ferrous concentrate into high quality scrap products Current annual treatment > 2,5 million tons of bottom ash, Capacity under construction > ton Employees > 120

6 Conventional BA treatment proces Bottom Ash Conventional treatment Sieve/ Magnets/ ECS NF concentratesoldto Sink/Float Fine HNF & LNF lost in Mineral fraction Sink / Float Relative low efficiency High % NF metals rest in Bottom Ash HNF LNF

8 Technical challenges Knowledge Theoretical knowledge of the Delft University of Technology Experience of current annual treatment of > 2,5 million tons of bottom ash Characterisation of specific bottom ash flow: Inashc0 Laboratory: Moisture content Particle size distribution NF contents (heavy and light NF characterisation) Operatability test

9 Installation examples

10 Bottom ash Mineral aggregates

11 Dutch legislation - CUR % -30% replacement of primary gravel and sand

12 AEC Aggregate application AEC aggregates replace primary gravel and sand in concrete products

13 AEC Aggregate application Concrete blocks Sewer pipes

14 Central Upgrading Facility Further treatment of NF concentrate from ADR operations

15 Central Upgrading Facilities

16 Financial Impact ADR Technology: Low cost No impact on environment (no waste water, no extra dust, marginaluseof electricity) Central Upgrading Technology: At same cost level as sink-float operations No impact on environment (no waste water, no emissions, marginal use of electricity High quality scrap represents best possible value from available ash contents Off take through Fondel marketing and trading channels guarantees premium prices

17 ADR build up at AEB Amsterdam

18 To summarise Convert ash into valuable raw materials 1. Recovery of more non ferrous metalsdown to 0,5 mm 2. Reuse ash minerals in alternative markets (NL Greendeal - non IBC) 3. Decrease carbon footprint for WtE facilities
