Sus­tainab­le substrates

Our gro­wing media are high-per­for­mance pro­ducts that satisfy our cus­to­mers’ all-round qua­li­ty requi­re­ments. We will, into the future, sell substrates that meet aspi­ra­ti­ons for social and eco­no­mic accep­ta­bi­li­ty and eco­lo­gi­cal com­pa­ti­bi­li­ty even more ful­ly, the­se needs being well cap­tu­red by the term ‘sus­taina­bi­li­ty’. This will invol­ve step­ping up our invest­ment in rese­arch and development.

More detail­ed infor­ma­ti­on on our sus­taina­bi­li­ty goals and the mea­su­res out­lined below is given in our latest Sus­taina­bi­li­ty Report.

Pro­cu­re­ment practices

Our ‘Sus­taina­bi­li­ty gui­de­li­nes for sup­pliers’, in for­ce sin­ce 2012, aug­ment the selec­tion cri­te­ria for our sup­pliers; they con­tain requi­re­ments for uphol­ding human rights, for employees’ working con­di­ti­ons and for envi­ron­men­tal stan­dards, as well as a busi­ness ethics code. The stan­dards this docu­ment defi­nes, and their adop­ti­on, are a pre­re­qui­si­te for all sup­ply agree­ments with Klasmann-Deilmann.

Respon­si­ble extrac­tion of raw materials

  • Peat extrac­tion sole­ly on degra­ded peatland
  • Pris­ti­ne bogs have been desi­gna­ted pro­tec­tion are­as (sin­ce 1981 as for Lower Sax­o­ny) and are left untouched
  • Use of peat­land com­plies with the Code Of Prac­ti­ce of the Euro­pean Peat and Gro­wing Media Asso­cia­ti­on (EPAGMA)
  • We sup­port the deve­lo­p­ment of the Respon­si­b­ly Pro­du­ced Peat (RPP) eco-label

Mea­su­res fol­lowing peat extraction

When extrac­tion of the raw mate­ri­al has come to an end, the are­as in ques­ti­on are pre­pa­red in line with requi­re­ments. Sites under res­to­ra­ti­on are made per­ma­nent­ly avail­ab­le as bio­to­pes for con­ser­va­ti­on and cli­ma­te pro­tec­tion pur­po­ses. Sin­ce 1960, we have re-wet­ted, affores­ted or made avail­ab­le to agri­cul­tu­re a total of 8,680 hectares.

CO2 reduc­tion strategy

We are pur­suing various pro­jects to redu­ce or off­set the emis­si­ons we cau­se. The­se form part of our CO2 reduc­tion strategy.

Mea­su­res to avoid the use of fos­sil fuels or to direct­ly cap­tu­re CO2

  • Affore­sta­ti­on
  • Manage­ment of woodland
  • Manage­ment of short-rota­ti­on fores­try (SRF) plantations
  • Pro­duc­tion of heat ener­gy from cor­po­ra­te-owned SRF plantations


  • A fun­da­men­tal princip­le is ‘water befo­re rail befo­re road’
  • Reduc­tion of pro­duct weight to opti­mi­se capa­ci­ty uti­li­sa­ti­on of trans­port units
  • Incre­a­sing the pro­por­ti­on of alter­na­ti­ve sub­stra­te com­pon­ents to 15% by volu­me of the annu­al pro­duc­tion total by 2020

Raw-mate­ri­als extraction

  • Enhan­ce­ment of sus­tainab­le land management
  • Rapid retur­ning of for­mer extrac­tion sites to nature
  • Con­duc­ting a sci­en­ti­fic stu­dy on emis­si­ons from extrac­tion areas
