Moola - der Bodenverbesserer

The name of our biochar is Moola, that DU: willkommen in der Umwelt produces on three pyrolysis installations. Moola is English and colloquially means “coal”

This biochar is not a fertilizer, but a carrier substance that serves the periodical storage of essential nutrients and water. The biochar provides habitats for useful microorganisms long-term.

In order to be able to use the soil improving qualities, biochar should be charged up with nutrients and water before the insertion.

An additional vaccination with microorganisms (for example EM-a) enhances the biological activity, which makes the fixed nutrients available sooner.

The insertion of untreated biochar can lead to a short-term fixing of nutrients and water that enables an inhibition of plant growth.  Therefore an insertion of untreated biochar towards the end of the vegetation period in autumn is recommended.

Building humus with biochar

Biochar doesn’t just increase the efficiency of fertiliser. Biochar ensures humus building. Especially on sandy soils, inserting biochar can increase the humus building by 0,1 to 0,2% per year, the humus content increases.

Test series done by the technical college of Osnabrück and the university of Hohenheim show a topsoil that clearly has improved regarding its nutrient content after being fed with enriched biochar.

What has been a trend in Switzerland and in Scandinavia for quite a while now, shall as well be introduced to Swabian gardens.

In Switzerland and in Scandinavia, farmers and hobby gardeners have been working with this natural product, that is enriched with nutrients (for example nitrogen), for quite some time.

Like a sponge

In contrast to traditional fertilizers the new type of biochar called Moola, refined with microorganisms and nutrients, is not going to be flushed out into the groundwater by rain. Instead biochar acts as a sponge in the ground, saving trace minerals and nutrients supplied to it. This continues until the smallest of roots from the plants above reach it and feed off of it.

DU: has been producing biochar for two years now with the bulk of the buyers coming from Sweden and the alpine regions in Germany. In these regions biochar is a highly sought-after soil enhancer. At the moment one pyrolysis plant is operational. Until the beginning of next year two more are expected to be brought online in Eislingen and Ebersbach. This allows us to produce up to 600 tons of biochar a year. This is the equivalent of 30 road trains (40 tons each).

Biochar reduces carbon

Once optimally charged with nutrients, biochar displays another one of its strengths. Whoever introduces the product into their garden or field will turn these areas into carbon reduction zone. “Carbon dioxide is actively being bonded from the atmosphere and taken into the ground for the long run”, Zimmermann explains.

The desired side effect: During the production of biochar water is heated up. Up to 150 kilowatt hours (kWh) can be produced by the pyrolysis plant per hour during a three-shift operation. This would enable DU: to supply around 390 homes with a year´s worth of electricity. However the major share of the energy gained from the heated water (around one million kWh per year) is used in the company´s own PET recycling plant. Here plastic flakes are being washed as part of their recycling. The rest is used to heat the family company´s recreation rooms.

Wee-wee one for science (maybe too vulgar)

250.000 people attended the German Protestant Church Congress in Stuttgart last year. There clever Christians set up toilets which had been spiked with biochar. The urine of the attendees was absorbed and transported up the mountain to the Hohenheim University in the district of Plieningen. Agricultural science students applied the Biochar to their orchard of Stuttgart´s oldest university for scientific purposes.

Terra Preta do Indio


This is the Portuguese name for a substance, which appears to have several fantastical attributes. The press has gone head over heels with reports of this so called “black gold”. Within the scientific community there is hope that through the use of this black earth two of humanities biggest problems can be solved: climate change and the food crisis.

The following effects can be reached through the application of Biochar:

  • Improvement on the soil structure (“Terra-Preta-effect”)
  • Enhanced water absorption and water saving capability
  • Promotes growth of plants
  • Better resilience of plants against illnesses and pests
  • Stable yield even in unfavorable weather conditions
