1 Aikan Technology - Provided by Solum Group Two phase AD and composting a way of handling waste and converting it to resources Presented by: Lars Møller, Prepared by: Henrik Mortensen, Business Development Director

2 Agenda Aikan Technology Company background Aikan Dry AD Mechanisms and Performance - Biogas/Compost specification - Pre treatment for landfill - Pre treatment for incineration or Refuse Derived Fuel Aikan Technical Aspects Finacials Conclusion

3 Aikan is a proprietary dry AD and compost Technology developed by the Solum Group Solum Group established in 1986 by Christian B. S. Christensen 250,000 tons of Biomass per year Employees: 40 Since 2003 Solum has been operator of our Aikan facilities. In 2009, Solum Gruppen was awarded the Danish Liberal Party Climate and Environment Award, which was presented by the former Danish Prime Minister Aikan Technology aproved by Technical Comitee in Malaysia 2012.

4 Solum Group handles various waste streams and produces valuable primary products Waste turned into : Energy Growth Media Fertilizers Other recyclables

5 Dry AD can help to make value out of waste that has an organic fraction!

6 Dry AD can be used for Municipal Solid Waste Wet AD cannot Dry AD Robust towards impurities. Can handle different and fast shifting waste streams. Waste is not being moved during the process, avoiding risks for blockages of pumps, moving parts etc. Inhibition of biogas biology is avoided due to batch processing

7 Dry AD can be used for Municipal Solid Waste Wet AD cannot Wet AD Waste must be made into a pulp The pulp must be pumped into a reactor tank Impurities in MSW clog pumps and filters Wet AD process is sensible to inhibitation

8 Technical Aspect: Wet AD in principle

9 The performance of an Aikan Dry AD and Composting system relies on the 3 steps: Hydrolysis: Methane production: Composting:

10 Commercial Market Position - IP development Unique 3-step integrated HSAD and IVC process Solid waste remains untouched inside the process module during methanation and composting Patent 1 issued 2012 in US. Patent 1 issued 2013 in US. The Aikan brand is registered in EU and Thailand Note (1): HSAD = High Solids Anaerobic Digestion. IVC = In Vessel Composting

11 Aikan Technology has the largest flexibility of all Dry AD systems on the market. Aikan is flexible Clean/pure organic waste => high quality compost Less clean waste => energy is extracted twice, Biogas is produced from organic fraction and the combustion value of the residues is increased during the proces, making the materials much more attractive for incineration and RDF Pre treatment for land filling for low quality input material Reduce volume of waste for land filling Reduce need for landfill gas collection Reduce leachate generation Reduce settling of landfill Substitute soil for daily cover

12 Aikan Technology: A unique two phase AD and composting system Our secret is not advanced technology - it s all biology! Organic fractions are first digested anaerobically Waste mass is watered and methane-producing bacteria are conveyed to the reactor tank for biogas generation and then composted Waste is untouched in the modules, and air is drawn through it

13 Aikan system balance diagram 10 kwh electricity 1000 kg Biowaste 200 kg Woody Structure Aikan features for pr ton of Biowaste in a Scandinavian climate 400 kg Compost 50 kg of waste 200 kwh electricity 200 kwh heat 10 kwh heat 20 kwh diesel

14 Feedstock Options for Aikan Plant The Aikan Dry AD Technology can use a very large variety of different organic feedstocks. -Source-separated organic household waste -Municipal solid waste -Park and Garden Waste -Farm waste -Catering kitchen waste -Grease trap waste -Energy crops -Screenings from other plants -Organic waste from agriculture -All kinds of horticultural waste -Food waste, including food wrapped in plastic -Organic residues from industrial food processing -(vegetables, oil, meat ++) -Dewatered sludge from sewage treatment plants.

15 Aikan Performance: Outputs from 1 ton (biodegradable organic waste after removal of plastic) Up to m 3 biogas (minimum 70 % methane) Biogas is flexible: Used for CHP - Equals approx 200 kwh electricity and 1400 MJ heat Transported in a pipe line to external power/heat plants Upgraded and used as fuel for cars 350 kg of 0-10 mm compost Nutrient rich Fully sanitized Control and treatment of odours Stabilized organic matter

16 Aikan Performance High Methane Quality Biogas produced at an Aikan plant contains on average 70 % methane. Depending on feedstock quality and other parameters, the day-to-day performance lies within 65 to 75 % percent methane.

17 Aikan Performance Compost Quality Compost delivered from an Aikan plant has a precisely defined quality and can be used as a substitute for conventional NPK fertilizer. 1 ton of compost contains the following nutrients (example specification): -Nitrogen total: 11.8 kg -Ammonium-nitrogen: 2.0 kg -Nitrate-nitrogen: 0.0 kg -Phosphorous total: 6.5 kg -Potassium total: 5.8 kg -Magnesium total: 1.3 kg -Sulfur total: 2.6 kg -Lv, conductivity value (10mS/cm): 18 -Lt, conductivity number (10mS/cm): 31 -ph-value, acidity: 7.2 -Rt, reactivity number: 7.3

18 Aikan Dry AD can be pretreatment for incineration/ produce Refuse Derived Fuel Incineration can be made more efficient and less costly through the use of Aikan Technology as pretreatment or to produce dry RDF: the Aikan process improves the calorific value of the organic matter and product residues / increases the heating value of the products for energy production The overall energy in the residues from the Aikan Dry AD System will be much higher than if the entire waste stream was incinerated. Reduced / removed need for support oil to maintain the incinerator temperature The CAPEX of the incinerator is considerably reduced as the Aikan process reduces the waste volume, without reducing the energy output from the incinerator

19 Aikan stepwise - Simple and efficient Biogas Compost Waste Presorting Recyclables RDF Landfill

20 Easy handling of recyclables Presorting can be more or less sophisticated Aikan works no matter which solution. Heat from biogas engine can be used for drying of recyclables and RDF or drying of compost. Remaining impurities can, without health hazard, be sorted out after composting of the sanitized MSW

21 Technical Aspect Technical Aspects Land area requirements (hectares) 20 modules; 4.4 hectare 35 modules; 6.2 hectare 50 modules; 11.0 hectare Manpower requirements - 20 to 40 during construction, and 5 to 10 new for operating a 20 module facility - many sorting persons can be employed in countries with cheap labor Delivery time (design, build and commissioning) Design 2 months Construction 8-12 months Commissioning 1 months Planned Downtime /Planned Maintenance schedule No downtime. Waste can always be treated due to batch approach

22 Technical aspect: Robustness and no down time Strong machinery. Many standard components. Simple solutions. Treatment paradigm can be adapted to situation.

23 Technical Aspects: Flexibility via incremental expansion

24 Technical Aspect Technical Aspects Training is key. Controlling and support. Security high due to gas production in reactor tank When supplying and commissioning a plant Solum secures the training of the staff. Plant manager will be trained in DK 2 weeks in advance. Local staff by PM and Solum at plant. One module is followed day by day. Run by PLC system. But people matter. Support by Solum via the Internet Our competitive advantage irt. Bekon, production of gas in the reactor tank instead of the modules.

25 Aikan Technology is characterized by Our Know How built into the PLC system Stable energy output Nutritious compost Easy handling of recyclables Flexibility Robustness No downtime
