2 CAMBI S BUSINESS AREAS Biosolids: Plants for enhanced biogas production from municipal & industrial sludge Biowaste: Plants for biogas fertilizer from source-separated organic waste Operations: Cambi Operations provides support and operation services to maximize plant performance

3 CAMBI ACHIEVEMENTS Established in Offices in Norway, Denmark, UK, Germany, Korea, China (rep Office) and USA Cambi is the world leader in Advanced Anaerobic Digestion, having delivered 27 plants worldwide since 1995 and 14 more are under design/construction, with total treament capacity of 920,000 metric tons of DS (dry solids)/year Treatment capacity for sludge and biowaste equivalent to 31.5 million people Production capacity of 2270 GWh thermal energy (biogas) and 900 GWh green electrical power, when using gas engine cogen Odd Egil Solheim (inventor) The first day of the future, is tomorrow Green energy production replaces 900,000 tonnes of fossile CO 2 emissions. Avoidance of methane emissions from landfills, less transport, etc. comes in addition (about 3 mill tons CO2 equivalents) Cambi THP is an eco-friendly Paradigm-shifting Technology, dramatically improving design and operations, and helping EPC contractors win turnkey biogas plant contracts

4 CAMBI & CLIENTS WIN 7 AWARDS WORLD-WIDE SINCE 2011 Paris/World 2014: Cambi won the Water Technology Company of the Year Distinction at the Global Water Summit, Paris, 7-8 April 2014, for unrivalled domination of the market for large-scale municipal installations featuring thermal hydrolysis technology for sludge treatment. Norway/World 2013: CAMBI won Ernst & Young Entrepreneur Of The Year, category Services: CAMBI's sludge treatment technology is today recognized as world leading.. The Jury pointed out that CAMBI invests huge amounts in R&D in cooperation with universities both in Norway and abroad. UK 2013 : At the annual Institution of Chemical Engineers awards dinner, the SBAP (Cambi) project at Davyhulme won first place in the Energy Award category for its submission Turning Black Gold Green! the best project to demonstrate innovation in renewable energy, alternative energy sources, efficient energy UK, 2012: CAMBI has built 2 AD Plants for Northumbrian Water (NWL), Bran Sands & Howdon, both using CAMBI s Thermal Hydrolysis Process. NWL won the Renewable Energy Award under the Sustainability Leaders Awards (the edie Awards for Environmental Excellence). Norway, 2012: The Norwegian Research Council's Innovation Award goes to Cambi and the Municipality of Oslo for the Cambi biogas plant at Nes, Norway, serving the Capital of Norway, Oslo. Biogas is upgraded to liquid biomethane and used as fuel. The nutrients from food waste is recycled as bio-fertilizer Norway 2012 : Cambi got the Innovative Environmental Technology Award at the Technoport conference in Trondheim. The award criteria were that the company has shown great innovation ability and developed an environmental technology that gives lower strain to the environment than alternative solutions. USA, 2011: Water Environment Research Foundation (WERF) Recognizes DC Water's Biosolids Project with Award for Excellence in Innovation as One of the Greenest Projects in the World (2012)

22 CAMBI XXL: DAVYHULME, UK, 91,000 t DS/year (1000 MLD) CAMBI Advanced digestion: Class A Cambi Cake to agriculture and incineration back-up Increaseas capacity at existing incinerator by 14,000 tonnes dry solids/year (avoided new incinerator) 60% VS reduction, 2.5 times more sludge through existing digesters 10 MW green electricity generation (gas engines), and steam to Cambi Cambi THP B12-4x5 reactors Raw sludge cake import 8 x 7500 m3 digesters

23 DAVYHULME, COMBINING ADVANCED DIGESTION WITH INCINERATION Digestion reduces volatile solids content which in turn reduces calorific value on a dry basis Dewatering is more influential than volatile solids content with respect to sludge calorific value 1% VS ~ 60 kj/kg; 1% DS ~ 140 kj/kg Digestion prior to incineration offers many benefits Reduced incineration requirement; better energy recovery; lower CO 2 footprint; Advanced digestion can increase capacity of existing incineration facilities Installation of TH can increase capacity at SG by ~ 14,000 TDSA

24 CAMBI SIGNIFICANTLY REDUCES CARBON FOOTPRINT Oslo EGE: 10,000 t CO2e/year DCWATER/Blue Plains: From 47,000-73,000 t CO2e/year Davyhulme: 32,000 t CO2e/year Bran Sands: 50,000 t CO2e/year [The] thermal hydrolysis pretreatment system at Davyhulme will reduce [United Utilities ] carbon footprint by 8% - the equivalent of removing 270,000 cars off the road for 30 years., March-April 2009, Worldwater Cardiff + Afan: 37,000 t CO2e/year

34 BASIC SLUDGE STRATEGIES - WORLDWIDE Digested cake is at the road fork of strategic planning of biosolids -- Best Practical Environmental Option is cake to agriculture but one may need to have the back up situation of subsequent drying/incineration in larger projects Digested cake to agriculture based on stackable stable low volume product it s a transport business is pasteurised product needed? Digested cake Class A Drying makes no sense for agriculture at most transport costs only if agriculture is not available or too expensive No agriculture Agriculture Capital and operating costs based on tonne of water evaporation or transport Drying 1MWh/tWE Drying size based on dewatering/cake volume Incineration 2MWh/tWE Autothermic cake is preferred ~35% DS Lowest cost option Cost/t transport Recycling of nutrients

35 CAMBI Project Profiles, examples New build digestion - avoids digester construction and reduces biosolids eg Dublin, DC Water, Brussels, Vilnius New build digestion plus regional plant - avoids digester construction and closes uneconomic small plants maximizes cogen, minimises biosolids eg Aberdeen, Bran Sands, Newcastle Digester upgrade plus class A - full Cambi replaces digester build out, eg Naestved, Kapuciska, Fredericia, Riverside (all high WAS plants) Digester upgrade class B WAS Cambi replaces digester build out (7.5% DS feed), eg Santiago, Munich (incineration), Digester upgrade to regional plant using existing digesters and import of raw sludge avoids digester build out and closes uneconomic small plants maximizes, cogen, minimises biosolids - eg Cotton Valley, Whitlingham, Manchester Daveyhume, Chertsey, Raw dryer, incinerator or lime stab replacement with new build economically driven larger plants eg DC Water, Newcastle, Cardiff, Swansea, Beckton, Crossness Codigestion & food waste: Combining TH of sludge and food waste, eg Ecopro, Växjø, Anyang City (Korea), Stavanger, Lillehammer (only foodwaste), Oslo (only food waste) New build to replace aerobic digesters??

44 B2 Logistics: The package unit is designed to be transported and settled as one, this includes the building where applicable. Lifting spreader bars are required during off loading, these can be provided by the lifting company or supplied with the B2 unit as optional extras. Should the package unit be required to fit within an existing building that has limited access it is possible to split the package in two locations after initially lifting it to the floor. Steelwork in red is for transport and lifting only. To be removed when the unit is settled.

(especially with poorly sorted waste) Evaluated and rejected by Cambi - Pulper systems, Drum screening systems - Cannot fulfill EGEs quality requirements - Low DS content, <10% Evaluated and selected by Cambi, BioSep The system has unique features - Extremely clean reject - Low loss of food waste - Clean accept (treated food waste) - Low installed power (55 kw) - High DS content 25-32%, alllows 16-18% DS to THP with higher steam efficiency - Low wear

85 TYPICAL MASS BALANCE Product I/O Comments Biowaste 1000 kg Food waste ~80% (VS content) Sorting reject+grit kg Typical 10% Organic reject 10% Inorganic material Bio-fertilizer (output) 300 kg/t To agriculture use Effluent water (output) 1,75 m3/t To agriculture use or to WWTP Biogas at ~65% CH m 3 /t 150 m 3 on pure biowaste (70% VSR) kwh Electricity (gas engine) kwh/t CHP

86 BIOFERTILISER QUALITY & HANDLING 1 m3 of biorest contains: 8-10 kg Nitrogen, whereof 25% is ammonium NH4-N 1,2-1,3 kg phosphorus 2,5 kg kalium Issues: Minimum odour < 0,5% plastic in weight Good nutrient content (comparable to mineral fertiliser) Not increased amount of work for the farmers Optimal logistics and storage system A cost saving product for the farmers Bio-fertilizer contract: Felleskjøpet Agri will dispose all the produced bio-fertilizer, m3 bio-fertilizer will cover 30 km2 land

87 CO-OPERATION POSSIBILLITIES WITH NATIONAL PARTNER Most suitable co-operation models to avoid high costs for all parties (and especially the end customer) Civil Define scope of supply Engineering & design Procurement Installation Completion & commissioning Guarantees (-Performance test/guarantees) The main objective is to be competitive in all projects
