The Laboratory for testing and research of solid biofuels, biowaste and compost (LITBK) is specialized laboratory, equipped with new modern highly sensitive analytical equipment - production of leading companies for analytical, research and expert activitis.


LITBK is comparable to that of the best international laboratories and carried out:


• Sampling of solid biofuels, biowaste and compost


• Testing of solid biofuels (wood and non-wood pellets wood and non-wood briquettes, wood chips, firewood, forestry waste biomass, agricultural waste biomass as a feedstock for production of biofuels)


• Testing of firelighters for barbecueing, barbecue charcoal and barbecue charcoal briquettes


• Testing of compost,treated biowaste (compost, fermentation product, organic fertilizer produced by composting and anaerobic digestion and stabilized organic fraction from MBT); sludge; soil; waste


• Sampling of: solid biofuels; sludge; compost and soil improvers


• Environmental measurements




LITBK is accredited according to the requirements of EN ISO/IEC 17025 with certificate of accreditation No 192 LI / 10.09.2016. The validity of the certificate is up to 01.04.2020 (see certificate here, order for extension). LITBK is the first in Bulgaria specialized laboratory for testing of solid biofuels, biowaste and compost.
