1 Valorisation of organic household waste & greenery cuttings Olaf Fennis - Attero June 9, 2015, Brussels Agenda Introduction Situation in the Netherlands Situation in (North-West) Europe Case study Saarland (Ger) Round up 1

2 Introduction: Attero = biomass to energy heat power GWh Municipal solid waste kton/y Organics 100 kton/y 2 Waste to energy plants heat steam 30 ton/hour 250 kton/y 7 Digestion plants biogas green gas 11,7 M m 3 Organic household Waste kton/y biogas mobility gas (LNG) 100 k m 3 Landfills biogas power 20 GWh compost fertilizer 300 kton Greenery cuttings 3 65 kton/y 7 Composting plants wood biofuels 30 kton Introduction: Attero = biomass to energy Latest project: Bio-Energy Plant (BEP) Odiliapeel Thermal treatment of 30 kton wooden fraction of organic household waste 9 MWth steam December 2014 February 2015 March 2015 May 2015 August 2015 in operation 2

3 Situation in the Netherlands In 2012 total bio-energy production of 71,3 PJ of which: 15,6 PJ ~ 22% = BEP s burning wood (e.g. greenery cuttings) 8,8 PJ ~ 12% = digestion plants (e.g. organic household waste) Total bio-energy production sites Digestion plants using organic household waste Total volume separate collected organic household waste in NL: 1,2 Mton Still 1,4 Mton in MSW is organic (~ 36% of MSW) Situation in the EU for biowaste One EU, so one goal through - Waste Framework Directive: 50% recycling of household waste in Renewable Energy Directive: 20% sustainable energy in 2020, 27% in Landfill directive: Reduction of landfilling valuable resources But large differences between member states in: - Energy resources (gas, coals, nuclear, renewables): different interests - Policy and programs for (bio)waste-to-energy - Government as stakeholder or privatized market Bans and taxes for landfilling Waste collection systems Gate-fees for treatment Common treatment techniques Regulation for compost / digestate utilization 3

4 Trends in NWE for biowaste to energy Most important trends in North-West Europe - EU recycling goals are leading in national policies - Incentive for reduction of landfilling - Upcoming regulation for landfill bans and high taxes (UK, Ireland, etc) - Big (financial) stimulation for alternatives like composting / digestion / BEP s - Separate collection of organic household waste grows (Germany) - Organic household waste is a growing, huge market! - Chances for digestion and BEP s are depending on stimulation programs - Segregation of organics from residual waste (MBT) is alternative: DISADVANTAGE: risks for contaminations in food chain through compost! - Contradictory policy: focus on resource recovery focus on heat distribution + gas resources - Governments, municipalities and treatment companies are busy creating alternatives: this takes time, knowledge and tendering procedures Big ongoing changes in national waste management programs! Saarland: strategy development for organic waste and greenery cuttings valorisation Aim Respond to heterogeneous greenery recycling concepts and export of organic waste from households Area of ARBOR assessment German Federal State of Saarland Saarland motives Legal amendment to increase material and energy efficiency standard for greenery cutting treatments (herbal and wooden biomasses) Political drive to increase regional recycling of organic waste from household in Federal State Saarland Cross-border synergies with the French region of Lorraine 4

5 Saarland: strategy development for organic waste and greenery cuttings valorisation Saarland greeneries potential: 92 collection and composting sites, responsibility by 52 Saarland municipalities Heterogeneous, decentralised situation No quality assured composts Saarland organic household potential: Separately collected, responsibility by Disposal Association Saar (EVS) Public Tender to other Federal States No high energy and material efficiency Wooden Mass: 25,000 tons/a Herbal Greeneries: 60,000 tons/a Household : tons/ a Saarland: strategy development for organic waste and greenery cuttings valorisation ARBOR scenarios: Decentralized collection and recycling hubs BEP s on wood for near district heating systems (min. 500 kwth or ORC) Option: Saarland anaerobic digestion (AD) plant for combined bio-waste Option: 40% of Saarland herbal greeneries in dry-digestion plant Lorraine Innovation: Integrated pyrolysis / HTC at AD for biochar production ARBOR strategy outcomes: Saarland task force Organic Waste Policy: amendment of Saarland Waste Law (2014), where EVS is solely responsible for all organic waste recycling (2018) LCA: reduction of GHG emissions: 26,000 tons CO 2eq / a Economic: keep public waste fees stable for inhabitants Commissioning regional greenery cutting + organic household recycling concept 5

6 Conclusions Trends in NWE are very promising for biowaste to energy initiatives: Many regions/councils are looking for alternative treatment driven by EU- and national incentives to reduce landfill and increase sustainable energy Chances for realisation depend on the puzzle of: - National policy and programs on waste, sustainable energy and resources - Regional initiatives for changing waste treatment (tenders, contracts, etc.) - Local options for fuel supply, locations, energy demand, operating party, etc. Many successful examples are available - Techniques for digestion and combustion are proven - Suppliers and treatment companies have solid references - Treatment companies with know-how and ambitions are available - Business cases can be feasible, but often depending on stimulation programs ARBOR 1 resulted in some valuable projects - Saarland - Stoke on Trent - And many others SO LET S CONTINUE!! Thank you! Biowaste-to-energy is often a challenge, but has great prospects! olaf.fennis@attero.nl Mobile:
