Workshop on Inventories and Projections of Greenhouse Gas Emissions from Waste 8-9 March 2006, EEA, Copenhagen Use of FOD for estimation of methane emissions from municipal solid waste in the EU25: ‘Outlooks’ Under contract with the European Environment Agency Alejandro Villanueva European Topic Centre on Resources and Waste Management
What is the goal of the ’outlooks’ project?
Outline 1. Background for the projections What information did we use to estimate CH 4 generation from landfills? – IPCC methodology – MSW only! 2. Key parameters Activity data: Composition of the landfilled waste Amounts landfilled: and Methane recovery ratios IPCC methane oxidation parameters: MCF & OX 3. Future work Under contract with the European Environment Agency
Background for the projections FOD
Background for the projections FOD vs massbalance - food waste
Background for the projections FOD vs massbalance - wood waste
Background for the projections FOD vs massbalance: years back needed
Background for the projections FOD A modification of the draft IPCC spreadsheet
Background for the projections FOD A modification of the IPCC spreadsheet Municipal Solid Waste (MSW) only ! The reason: An econometric model has been developed in the ETC/RWM, but for MSW only
MSW generation projections
Biodegradable waste amounts captured Under contract with the European Environment Agency Origin Treatment Waste fraction Households Source - Separated fractions: Mech-Biol. Treatment Export Incineration Recycling (incl. composting) In MSW (contains 20-50% biowaste and 10-25%paper) Sewage sludge Markets, commerce and offices Park and garden waste Sewage sludge Biowaste Wood Paper ?

4 Key parameters Activity data: Composition of the landfilled waste Amounts landfilled: , , and Methane recovery ratio Oxidation rates: MCF & OX Under contract with the European Environment Agency
1. Composition of the landfilled waste Typically in reports from national research institutions / consultants
LANDFILLED WASTE COMPOSITION OXIDATION IN THE LANDFILL (MCF, OX) CH4 RECOVERY DATA CERTAINTY WASTE AMOUNTS % TO LANDFILL
2. Amounts landfilled 2.1 Total amounts generated
2. Amounts landfilled 2.2 Percentage of MSW to landfill
The Landfill Directive targets MSW generation and BMW landfilling trend in the EU15 Under contract with the European Environment Agency OBS!: Only MUNICIPAL biodegradable waste: no sludge, no industrial waste 1999: Directive enters into force 68 % 75 % 50 % 35 %
Landfill Directive targets Under contract with the European Environment Agency Are MS on the way to meet the LD targets? Ref
2. Amounts landfilled 2.2 Percentage of MSW to landfill
LANDFILLED WASTE COMPOSITION OXIDATION IN THE LANDFILL (MCF, OX) CH4 RECOVERY DATA CERTAINTY WASTE AMOUNTS % TO LANDFILL
3. Methane recovery
LANDFILLED WASTE COMPOSITION OXIDATION IN THE LANDFILL (MCF, OX) CH4 RECOVERY DATA CERTAINTY WASTE AMOUNTS % TO LANDFILL
4. Oxidation in the landfill
LANDFILLED WASTE COMPOSITION OXIDATION IN THE LANDFILL (MCF, OX) CH4 RECOVERY DATA CERTAINTY WASTE AMOUNTS % TO LANDFILL
Interim results Under contract with the European Environment Agency ….
Future work in the ETC/RWM 1. Refinement of the 4 key parameters 2. Extension of the projections to: 1. Other landfilled organic waste fractions 1. Industrial waste 2. Sewage sludge 2. Other waste treatment technologies (composting, incineration) Under contract with the European Environment Agency
