PRINCIPLES OF OUR RAW MATERIAL SELECTION The goal of the Kronen group is to operate and manage most of the raw material sites by itself.  The raw material sites are quality controlled, tested and certified by an independent body.    External suppliers must be certified by an independent bodies and have quality assurance schemes Long lasting supply chains are rated higher than short term gains on the spot market. Raw materials are sourced as locally as possible. The Kronen group is committed to substituting slow renewable resources with quick renewable resources wherever possible, without compromising on quality. MILLED WHITE PEAT The most commen way to exctract peat is milling.  The top layer of the peat bog is being milled when weather conditions are dry.  Once the loose peat has dried to a water content of 55% it is being harvested either by a vacuum or a mechanical harvester.  This cycle is being repeated a couple of times during the dryer periods of the year.   White Peat (H2 to H3) 3,5 -4,0 160-220 kg/m3(EN) Lasland sp z o.o., Przemtorf sp z o.o. fine, medium good water retention propagation, trays and bedding plants PRINCIPLES OF OUR RAW MATERIAL SELECTION The goal of the Kronen group is to operate and manage most of the raw material sites by itself.  The raw material sites are quality controlled, tested and certified by an independent body.    External suppliers must be certified by an independent bodies and have quality assurance schemes Long lasting supply chains are rated higher than short term gains on the spot market.
