1 Modern Business Concept of Mixed Municipal Solid Waste (MSW) Treatment Results with Feeling of Success Wiltrain Oy HLAD Engineering Oy Wiltrain Oy 1

3 MSW, City Waste in Philippines Who has the responsibility to take care? Organic waste should not be delivered to the landfills already banned and sanctioned in Europe and also administratively forbidden in Philippines but not yet sanctioned Is polluter pays principle generally approved? Lack of technically state-of-the-art landfills which are meeting Philippine legislation a serious problem Will the policy and sanctioning change after elections? Collection logistics and treatment are two different issues Wiltrain Oy 3

4 Why the incentives have not pushed the market to move? Income tax holiday for seven years; Duty-free importation of Renewable Energy machinery, equipment and materials within the first 10 years; Special realty tax rates; Net operating loss carry over to be carried for the next seven years; 10% corporate tax rate (not 30%); Tax exemption of carbon credits and tax credit on domestic capital equipment and services. However tested and proven technology exists BioThermal Wiltrain Oy 4

5 MSW Treatment! Why BioThermal treatment concept? BioThermal Concept combine Front End Treatment (FET), High Loaded Anaerobic Digestion (HLAD ) of biodegradable waste of MSW and modern combustion technology of Refuse Derived Fuel (RDF) in energy production Shall enhance materials & energy recovery from waste Results high energy efficiency in Fluidized Bed Boiler by using RDF fuel HLAD process biogas and electricity with high energy efficiency Low ash and end product amount for final disposal Energy efficiency of conventional MSW treatment is generally low Wiltrain Oy 5

6 MSW - Front End Treatment (FET) Fractions produced MSW FET 5 9 MJ/kg (MSW) Inert fraction Biofraction Combustibles 2 4 MJ/kg MJ/kg (RDF) Energy Electricity, heat (steam), district cooling Wiltrain Oy 6

7 Front End Treatment (FET) and Feed Preparation Important for Process Reliability For each case, it is necessary to design the FET to suit the intended biodegradable fraction In case of MSW treatment most appropriate equipment needed This is one of the main reasons to obtain reliable waste composition data from customers Wiltrain Oy 7

8 Modern & Reliable Process Technology for Organic Waste Treatment HLAD Engineering Oy s predecessor Protech AD Services with its partners have developed High Loaded Anaerobic Digestion (HLAD ) process which Is the most efficient treatment of biodegradable waste to biogas and with gas engine to electricity Takes in Municipal Solid Waste (MSW), animal manure and waste water treatment sludge all can be treated same time Is stable tested and proven process reliable in operation State of the art pre treatment guarantee high biogas yield Wiltrain Oy 8

9 Typical HLAD Treatment Plant for Bio Waste 1. MSW Pre-treatment (FET). Specially tailored for every project 2. Feed preparation including wet separation and homogenizer 3. Dewatered municipal sludge intake 4. Bioreactors 5. Biogas storage 6. CHP equipment (gas engines) 7. Mechanical dewatering unit of bioreactor digestate 8. Digestate thermal drying 9. Reject water treatment 10.Storage of thermally dried digestate granules Wiltrain Oy 9

10 HLAD process principle compared to conventional AD process 5 %DS Old Process 15 %DS HLAD Process Conventional AD process operates at the consistency of 5% of dry solid (DS) HLAD has the same amount of DS but substantially less liquid because of 15% DS content Smaller bioreactor volumes compared to traditional process Higher DS content means better buffering of process and better process stability Wiltrain Oy 10

11 Various Combustion Technologies can be used when using RDF in Energy Production Grate Firing Technology Traditional, robust, investment intensive and widely used method for waste incineration Mostly used for unsorted municipal solid waste (City waste) Moderate, and rather low energy production Fluidized Bed Technology Modern, flexible, cost efficient and efficient combustion & power production technology Good fuel flexibility, multi fuel operational mode possible, most preferred for Refuse Derived Fuels (RDF), biofuels, sludge, etc. Good energy production Gasification At the time, still under development for waste derived fuels utilization Wiltrain Oy 11

13 Mass Burning vs. BioThermal Concept Case Example & Investment Estimate for 1000 t/d MSW Capacity Mass Burning for MSW Estimated Investment ca. 230 M Waste Amount t/a Energy Content ca. 2,1 MWh/t (as received) Thermal Energy Production ca MWh/a Building Ratio 22 % 25 % Annual Electricity Production ca MWh/a BioThermal Treatment for MSW Estimated Investment ca. 160 M Waste for FET Treatment t/a Biofraction for HLAD: ca t/a RDF Fuel: ca t/a Reject: ca t/a Energy Content ca. 4,2 MWh/t (after FET) Thermal Energy Production MWh/a (RDF Fuel) Building Ratio 28 % - 30 % Annual Electricity Production Gas Engine (Biogas use) ca MWh/a FB Boiler ca MWh/a In Total ca MWh/a Wiltrain Oy 13

14 Advantages of BioThermal Treatment of MSW BioThermal Method Improved power output (20-25%) Multi Fuel mode possibility Landfill waste 10% - 15% of total waste amount Ash waste < 10% of total waste amount Better recycling rate Carbon Credits possible to obtain Mass Combustion Landfill waste 20% 25% of total waste amount (ash, metals and other non combustibles) Typically, only MSW incineration Carbon Credits not available Wiltrain Oy 14

15 BioThermal Treatment of MSW Solution for Mixed Municipal Solid Waste (MSW) Combined treatment of biodegradable and combustible waste fractions using best available technology (BAT) consisting of Efficient Front End Treatment (FET) for mixed MSW High Loaded Anaerobic Digestion (HLAD ) process for biodegradable fraction conversion to biogas, electricity and heat High tech Fluidized Bed Boiler (FBB) for combustible fraction utilization in Combined Heat, Cold and Power (CHCP) mode District cooling as option, to ensure the most efficient utilization of energy content of MSW BUT it is not energy production it is energy efficient waste treatment Wiltrain Oy 15

16 Could a Modern Business Concept with BioThermal technology be a solution? Energy content of the MSW is better utilized Produced electricity from MSW is easy to sell Industrial off-takers of excess heat (steam, hot water) or cold (district cooling) is needed to achieve financial viability Could Public Private Partnership with LGUs be one solution? Industry cooperation so that win-win-win situation can be created Wiltrain Oy 16

17 Summary of PPP Integrated Waste Management Concept as Example MSW and industry waste treatment Electricity Fish processing?? Steam and hot water Davao???? Condensing Chiller Distillery Other LGU s to join? Inert reject to landfill Digestate Reject water as organic fertilizer Wiltrain Oy 17

18 Organizational / Managerial Feasibility of HLAD Engineering Small organization focusing only core competence of HLAD process and BioThermal concept. Involvement of local partners in implementation phase vital to ensure competitive solution Constant advisory teams in every technology area and business development to support HLAD Engineering operative management They are committed for the HLAD Engineering development project and willing to transfer their cumulated tacit knowledge Sales organized on success fee basis The individuals are senior business leaders and the companies technically competent Focus in SEA (Philippines) and China due to the conducive business environment Wiltrain Oy 18
