1 Audit and Test Report: Date: BEA Inspection according ENplus Client: Velpel d.o.o. Attn.: Industrijska bb Ivanić Grad Croatia Subject: Wood pellets production Velpel d.o.o. plant in Ivanić Grad, Croatia Content: Site Audit 2015 and pellet testing according to ENplus (initial inspection) Order: According to the order from Date of audit and sampling: by Dr. Martin Englisch Receipt of samples: and Ref: Eng Approved Testing and Inspection Body IS003 / PL232

2 1 SCOPE OF WORK Inspection of the wood pellet production plant especially of quality measures, evaluation of quality related documents and internal testing of product quality of wood pellets production according ENplus requirements. A sample of the production is to be taken and tested according EN ISO for verification of pellet quality. 2 SCOPE OF APPLICATION The test results given in this report have been obtained under the specific conditions of the individual tests. They shall serve as proof for the conformity of the sample(s) tested. The client is responsible for the conformity of products with ENplus regulations which will be assured when quality assurance measures according ENplus regulations are continuously applied. 3 INSPECTION AUDIT The inspection audit was carried out according ENplus Handbook 3.0 (version August 2015) on by Dr. Martin Englisch attended by and Mrs. Renata Petrić (TÜV Croatia d.o.o.). Duration of audit was approximately 4 hours. Responsibilities in the factory are assigned clearly, a company organogram exists. The responsibility in the company is divided as follows: Contact person: General management: Quality manager: Responsible for the production of pellets: Responsible for quality assurance: BEA Page 2

3 3.1 Products Certified products Dimensions ENplus ID Certification body Delivery to end customer Brand name wood pellets EN ISO , class A2 6 mm not yet certified HFA Pellets will be sold in 15 kg bags. There is no part load delivery to end user. Velpel Production amount New production, started end of 2014 Storage capacity ~ 500 t bagged pellets stored on pallets in a hall 3.2 Raw material Origin of wood Source raw material Raw material species Form of raw material Raw material storage 100% purchase from external suppliers 100 % Chemically untreated wood by-products and residues (1.2.1 acc. ISO ) 20% oak, 80% beech ( Broad-leaf without bark acc. ISO ) Sawdust and offcuts from wood processing companies (sawmills) The raw material is stored outside on paved ground, partly under roof. Control and documentation of raw material All incoming raw material is visual inspected and hand sorted before putting into the chipper. Suppliers A list of suppliers exists. Sustainability of raw material Other raw materials used (e.g. pressing aids) An unknown part of the raw material is FSC certified. No additives or binders are used. BEA Page 3

4 3.3 Production process Raw material preparation Drying Separation of contaminants and impurities Pellet production Removal of fines Non complying pellets Documentation of failures, breakdowns and maintenance Carbon footprint of production Chipper and hammer mill. 2 drum-driers. Manual sorting input; metal separator before hammermill. The dry raw material is pelletized by 2 flat die presses and cooled by a counter current cooler. Fines are removed by 2 vibrating sieves with suitable size and sieve aperture, dust is removed by air separators. A possibility for separation of low quality batches exists (manual). A shift book exists containing all relevant information. Will be calculated next year since production started recently and not enough data are available. 3.4 Quality control measures The factory production control is carried out in accordance with the requirements of the regulations. Tests are done regular and are documented properly. Parameter Test frequency Test equipment Moisture once a shift humimeter Bulk density once a shift Bulk density cylinder Mechanical durability once a shift Tumbler Length once a shift Caliper rule Fines once a shift visual, full bag once a day 3,15mm sieve Instruments are maintained properly, calibration and/or performance tests are done.

5 3.5 Quality assurance Quality management system Documentation raw material Customer complaints Documentation of outgoing goods Check of temperature of outgoing goods Individual documents for most important quality related topics are available, e.g.: Instruction for incoming raw material Instruction of self inspection Customer complaint management Check and documentation of In- and Outgoing goods All incoming raw materials are documented and are checked by staff. Since additives are not used, there is no documentation. Customer complaint management is implemented. A form is available on Internet see 3 complaints are recorded since production started Documentation of outgoing goods is done according to the requirements. Not necessary, no part load delivery. 3.6 Retain samples Retain samples pellets Not necessary, only bagged pellets. Retain sample labelling - Storage for retain samples Labelling Requirements concerning labelling will be implemented as soon as the certification process is finished. 4 SAMPLING Samples were taken following the principles of EN Two 15 kg bag were taken from production during the audit. The sample was taken by the auditor to the auditor s lab. BEA Page 5

6 The internal lab was installed shortly before the audit and self-inspection started at this time. Mechanical durability was found to be slightly below requirements and was improved immediately checking quality with the new lab. A new sample was submitted to BEA Complying of the production with requirements for mechanical durability was proofed by self inspection protocols. 5 TESTS Testing took place in September-October The tests were carried out according EN ISO in cooperation with a subcontractor (heavy metals). 6 PELLET LAB ANALYSIS RESULTS Sample sample from ar as received db...dry basis Limit values Pellets according ENplus Standard unit Class A1 Class A2 mechanical durability EN [%] 98,5 1 98,0 97,5 bulk density EN [kg/m³] BD BD 600 moisture content EN [%] 6, ash content 550 C (db) EN [%] 1,1 0,7 1,2 net calorific value (ar) EN [MJ/kg] 16,8 16,5 16,5 net calorific value (ar) EN [kwh] 4,7 4,6 4,6 Sulphur content (db) EN [%] <0,005 0,04 0,05 Chlorine content (db) EN [%] 0,005 0,02 0,02 Nitrogen content (db) EN [%] 0,23 0,30 0,50 pressing aid / additives - [%] none 2 2 dimensions fines (< 3,15 mm) EN [%] 0,45 0,5 * 1 0,5 * 1 lenght (3,15 L 40 mm) EN [%] 99,6 > 98 > 98 lenght (40 L 45 mm) EN [%] 0,0 1 1 lenght ( > 45 mm) EN [amount] 0,0 0 0 diameter EN [mm] 6 6 or 8 ± 1 6 or 8 ± 1 heavy metals Chromium (db) EN [mg/kg] < Copper (db) EN [mg/kg] 1, Zinc (db) EN [mg/kg] < Lead (db) EN [mg/kg] < Mercury (db) EN [mg/kg] <0,05 0,1 0,1 Cadmium (db) EN [mg/kg] <0,2 0,5 0,5 Arsenic (db) EN [mg/kg] <1 1 1 Nickel (db) EN [mg/kg] < ash melting behaviour (ash preparation at 815 C) shrinking temperature SST CEN/TS [ C] deformation temperature DT CEN/TS [ C] hemisphere temperature HT CEN/TS [ C] flow temperature FT CEN/TS [ C] BEA Page 6
