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 sampl(es) 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 for the Certification of Wood Pellets for Heating Purposes (version 3.0 from August 2015) by Dr. Martin Englisch attended by Mr. Igor Milekić and Mr. Nemanja Aleksić. Duration of audit was approximately 3 hours. Responsibilities in the factory are assigned clearly, a company organigram exists. The responsibility in the company is divided as follows: Contact person: Mr. Igor Milekić Director in charge: Mr. Igor Milekić Quality manager: Mr. Nemanja Aleksić nemanja.aleksic@sparrow.rs Responsible for quality assurance: Mr. Nemanja Aleksić BEA Page 2

4 Sustainability of raw material Other raw materials used (e.g. pressing aids) No certification none 3.3 Production process Changes in 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 Storage of pellets Carbon footprint of production New stationary chipper Log handling system is new The whole woodyard was paved Some raw material is manually cleaned, majority of logs is debarked and chipped Material is dried with a directly fired drum drier Oversized particles and impurities are removed by sieves and stone traps. Metal separators are used Raw material is conditioned using water and is pelletized by 3 ring die presses. Pellets are cooled in 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. Non-conforming pellets are filled in big-bags and are sold to local customers at factory gate. A shift book exists containing all relevant information Pellets are stored in bags on pallets only. GHG emissions of production was calculated using the EPC XLS sheet: 30,3 gco₂/kg for bulk pellets 33,3 gco₂/kg for bagged pellets BEA Page 4

Instruments for quality control maintained properly, performance tests are done. Moisture device was at calibration on the day of the Audit. 3.5 Quality assurance Quality management system Documentation raw material Quality management is in place and based on SOP s which cover: Responsibilities Inspection procedure incoming logs Customer complaint management Procedure for self-inspection Requirements for lab equipment calibration and maintenance Is done accordingly BEA Page 5

6 Customer complaints Number and reason of complaints Documentation of outgoing goods Measuring pellets temperature at loading station External training of staff Internal training of staff Customer complaint management system is implemented. 0 complaints in 2015 Documentation of outgoing goods is done according to the requirements. Not necessary, no part load delivery Quality manager and additional shift manager attended EPC approved training. Included in quality management system 3.6 Retain samples Retain samples pellets Not necessary, only bagged pellets. Retain sample labelling - Storage for retain samples Labelling Labelling (delivery notes including dispatch form and bags) includes information required in ENplus handbook. All bags using own ID are approved by EPC or in approval state. 4 SAMPLING Samples were taken following the principles of EN Two 15 kg bag was taken from the bagging station. The samples were marked and were taken to the auditor s lab by the auditor. 5 TESTS Testing took place in December January The tests were carried out in cooperation with a subcontractor (metals).
