United States, Indonesia, South Africa, China, Europe, Malaysia, Canada, Russia, Brazil). Representation of BTG s pyrolysis process 6

7 Why Pyrolysis Practical solution to problems encountered in practically all biomass processing: solve logistic first at relatively low costs and high efficiency Decouple biomass resource from location where biomass becomes available and scale of application A variety of biomass feedstocks / structures can be transformed in a more uniform product (liquid) Produces bio-liquids which are easier to store and transport due to significant volume reduction of solid biomass of about 12 on average High overall efficiency of ~ 85%: Conversion of biomass to main & by- products (incl. heat and electricity) Relatively low investment costs Pyrolysis oil provides a viable link between the agriculture and (petro-) chemical industry. Utilize existing fossil fuel infrastructure by introducing bio-liquids in existing refineries to produce second generation biofuels - repurposing existing assets

8 Roll-out Fast Pyrolysis development timeline Start-up Empyro plant & Process steam boiler at FrieslandCampina Start construction 120 t/d Empyro plant in Hengelo (NL) Long-term FPBO supply contract signed Founding Empyro BV to demonstrate FP technology Establishment of BTG Bioliquids BV to commercialize BTG Fast Pyrolysis technology 2004 Delivery of 50 t/d FP-plant to Malaysia Large-scale co-firing test at Harculo Power Plant 1998 Start-up of 200 kg/hr FP pilot plant in BTG Laboratory BTG research BTG 1994 Empyro Netherlands BTG development BTG Co-production of FPBO, process steam and electricity BTG Delivery semi-continous test unit (50 kg/hr) to Shenyang (China) Knowledge transferred from UT to BTG Rotating cone reactor invented at University of Twente (UT)

10 EMPYRO - introduction OBJECTIVE Design, built and operate a 25 MWth fast pyrolysis plant to produce simultaneously electricity, process steam and fuel oil from woody biomass. Demonstrate use of pyrolysis oil in natural gas fuelled boiler for the production of process steam. Reference plant for BTG-BTL s Fast Pyrolysis Process 10 km from our headquarters (in Hengelo). KEY FIGURES Feedstock: clean woody biomass Capacity: 5 ton feed/hr (@ 5wt% moisture) Output: 3.2 t/hr FPBO 7.4 MWth steam 650 kwe Electricity Total investment: ~19 M 10

[ton] Production Scale up RCR very successful; 7 operators; One operator to run the plant at night; ~ 12,000 ton / 10 million litres produced; Runtime and production capacity gradually increasing; Oil yield around design value of 65 wt%; quality excellent from start Running at 3.3 tons of oil per hour (design capacity) at the moment Quarter

15 2015 Pyrolysis Oil Application 15

16 Industrial Application of FPBO Pyrolysis oil is co-fired with natural gas producing process steam for dairy company FrieslandCampina. Pyrolysis oil off-take agreement concluded for a period of 12 years (equivalent to ~ 200 million litres); Annual saving of 10 million m³ of natural gas. 100% back-up of natural gas (= guaranteed process steam supply) Pyrolysis oil is transported by tank truck from Hengelo to Borculo (~ 30 km). 16

17 Industrial Application of FPBO KEY FIGURES STEAM BOILER o Process steam: 40 t/hr, 20 bar o Pyrolysis oil : 5 18 MWth ~ 1 4 t FPBO/hr Schematic drawing of Process Steam Boiler at FrieslandCampina o Natural gas: 6 29 MWth o Overall efficiency: 95.5 %
