1 ASG Analytik-Service GmbH Juergen Bernath Technical manager ASG Analytik-Service GmbH Trentiner Ring 30 D Neusaess Phone

2 Accreditation EN ISO17025 for: Solid fuels: - wood chips, pellets & briquettes - waste wood - secondary fuels Liquid fuels (fossile and biogenic) LPG, CNG

3 Company history January 1992: Foundation of the company 1998: Accreditation by DASMIN for testing of fuels 2002: Extended approval for further solid fuel parameters 2003: Relocation to our own "tailor made" building 2006: Extension of building to accommodate a pilot plant 2007: Foundation of ASG do Brasil 2012: Further extension of the building (3 rd floor)

4 Staff 6 Ph.D. (4 Chemists, 1 Physicist, 1 Biologist) 4 engineers ( Dipl.-Ing. & Master degree) 16 lab technicians 4 others (accounting, mechanic, secretary)

5 Fields of activities Analytical laboratory for solid, liquid and gaseous fuels Consulting services Process optimization Production of QC materials and test fuels Manufacture of instruments for fuel analysis

6 Equipment I Equipment for sample preparation of wood biomass samples: - Sample splitter - Sieve shaker - Drying ovens - Mills (cutting mills, ultra centrifugal mill, cryo mill) - Microwave digestion Equipment for analysis of wood biomass samples: Entire equipment for all parameters according EN /3/4 plus: - GC-MS (e.g. for PCP and other organic contaminants) - ICP-MS (element analysis at trace level) - X-ray fluorescence (composition of ash or residues)

7 Equipment II Cutting mill SM 2000 Ultra centrifugal mill ZM 200 Cryo mill

8 Wood biomass analysis at ASG Sample preparation I Sampling is usually done by client # # # # # # ## Directly after sample arrival it is registered in our LIMS (Lab data system) by allocation of a definite lab ID-no. # # # # # # # # ## Optical inspection ( foreign matter ) and determination of hygroscopic water content# Determination of particle size distribution (EN )# # # ## For entire sample amount: 1 st step of homogenization by cutting mill (Retsch SM 2000)#

9 Wood biomass analysis at ASG Sample preparation II Preparation of a lab sample (ca. 500 g) by sample splitter# Determination of humidity (EN )# By using the ultra centrifugal mill, a sample with particle size of < 2 mm is prepared# This fraction is splitted again to obtain two identical samples, one for analysis and another one as retain sample#

10 Wood biomass analysis at ASG Analysis I # ## Further analysis acc. EN :# #- Ash content (EN 14775)# #- Calorific value (EN 14918)# #- #Mean density (EN 15103) ## #- Nitrogen content (EN 15104)# #- Sulfur & Chlorine content (EN 15289)# #- Heavy metals: As, Cd, Cr, Cu, Pb, Hg, Ni, Zn (EN 15297) # # ##

11 Wood biomass analysis at ASG Practical aspects I # ## Regarding ASG s total annual turnover, wood chip samples contributes less than 5% to it# But: Share of wood biomass (pellets + briquettes + chips) samples is about 40%# Effort for equipment for wood biomass sample preparation & analysis is about EUR (+ costs for salaries, building, accreditation, infrastructure, energy.)# In daily practice, clients do not ask for full EN analysis, main aspects are humidity, ash, calorific value and particle size distribution# # ##

12 Wood biomass analysis at ASG Practical aspects II In most cases, the reason for clients to ask for analysis is not a quality complaint, but a more commercial motivation:# - todays basis for selling wood chips are specific trading contracts # - usually such contracts do specify water, ash, CV and particle size# - a moderate deviation from this specification does not lead to technical problems in a CHP, but gives client a reason for further price negotiations! # - If possible, clients want to reduce costs for analysis to a minimum (of course..)# # ##

13 Wood biomass analysis at ASG Main problems/barriers? # ## Due to our experience, there are no unresolvable technical problems to run a high quality wood biomass lab.# Analytical methods are well described (but still with room for improvements). Preparation of a homogenous lab sample is possible, but:# There is a huge impact of how and where to take the samples. To generate comparable and traceable results, this step is the most important one! # Commercial statement: Today, wood chip analysis only would not cover costs of running an accredited lab ##
