NON-FOOD OPTIONS at FARM LEVEL Greenhouse Gas Accounting for Non-Food Options (A web-based approach of LCA modelling) Hannes Peter Schwaiger JOANNEUM RESEARCH Forschungsgesellschaft mbH 23 rd April 2008
2
ENFA - European Non-Food Agriculture, Final Meeting, 23-24 April 2008 2 Overview Defined fuel chains WP Objectives Web based tool Some examples / results Methodology: LCA, GHG emissions
3
ENFA - European Non-Food Agriculture, Final Meeting, 23-24 April 2008 3 WP 32 Objectives To identify 3 bio-chains for which LCA models are created (e.g. pellets, biodiesel, wood chips form SR systems) Produce a computer model for the selected chains Conversion of the model into a web-based file (asp files) Post the model on the internet as an user friendly interface

ENFA - European Non-Food Agriculture, Final Meeting, 23-24 April 2008 4 According to ISO 14 040 „Life Cycle Assessment“ Standard Methodology of IEA Bioenergy Task 38 „Greenhouse Gas Balances of Biomass and Bioenergy systems“ Recommendations of COST Action E9 „LCA of Forestry and Forest Products“ LCA- Methodology

ENFA - European Non-Food Agriculture, Final Meeting, 23-24 April 2008 5 Global Warming Potential, Functional Unit Greenhouse effect: GHGs in CO 2 -equivalents (CO 2, CH 4, N 2 O, CF 4 ) Equivalent factors: CO 2 1 CH 4 23 N 2 O 296 All results refer to the functional unit of: g CO 2 equivalents / km
6
ENFA - European Non-Food Agriculture, Final Meeting, 23-24 April 2008 6 Biodiesel and Fossil Diesel chains
7
ENFA - European Non-Food Agriculture, Final Meeting, 23-24 April 2008 7 Definition of fuel chains in ENFA: Biodiesel
8
ENFA - European Non-Food Agriculture, Final Meeting, 23-24 April 2008 8 Definition of fuel chains in ENFA: Bioethanol
9
ENFA - European Non-Food Agriculture, Final Meeting, 23-24 April 2008 9 Definition of fuel chains in ENFA: Biomass
10
ENFA - European Non-Food Agriculture, Final Meeting, 23-24 April 2008 10 Defined fuel chains in ENFA Biodiesel Austria: 23 chains Germany (Schleswig-Holstein) 4 chains Germany (Schwäbisch-Alb) 4 chains Bioethanol Austria: 21 chains Germany (Schleswig-Holstein) 9 chains Germany (Schwäbisch-Alb) 3 chains Germany (Brandenburg) 3 chains Germany (Bayern) 3 chains Fischer Tropsch Diesel (solid Biomass) Germany (Baden-Württemberg) 4 chains
11
ENFA - European Non-Food Agriculture, Final Meeting, 23-24 April 2008 11 ENFA – web-based approach All results are calculated using GEMIS and transferred to a database (MySQL) located on a server here at JR Database (MySQL) can be updated via web-interface The “Model” shows the results of GEMIS runs, the user defines the chains via drop-down lists in a “top down approach” Updating and extension with other datasets, fuels etc. is possible Possibility of changing input parameters in the “Model” to bring own data, but only for: Data which influence the results linearly and allow an easy recalculation
