Biochar applications at a glance
|Market segment||Sustainability advantages|
|BBQ charcoal||Locally produced from domestic waste wood. Sustainable and therefore protecting the rainforest. With quality seal and proof of origin.|
|Industrial carbon||High quality with highest purity up to activated carbon. A wide range of applications in the industrial sector.|
|Pharmaceutical carbon||Highest quality standards and the best possible hygiene and purity. A highly economical niche product.|
|Feed supplement||Avoids the addition of antibiotics, increases weight gain and improves health. An optimal stomach and intestinal flora and reduced methane emissions.|
|Culture medium and fertilizer||Soil optimization through demonstrably increased water and nutrient storage. CO2 storage through carbonisation of the substrate while simultaneously increasing the value of the cultivated areas.|
|Gardening and landscaping||CO2 negative. Substitute for peat. Renewable, avoidance of further peat extraction.|
|Garden||Soil improver, concentrated, CO2 negative and can be used successfully in any soil. The highly efficient future in the fertilizer sector.|
Cascade use in agriculture
The multi-talent plant biochar achieves multiple benefits: the biochar is suitable as a silage aid, feed additive or bedding. It serves to promote animal health and to reduce odorous substances and emissions in manure and slurry. Through subsequent use in the biogas plant, the biochar effectively contributes to increase the biogas yields and quality of the biogas slurry.
After being applied to the fields, the biochar serves as a carbon fertilizer and pesticide as well as a soil additive for the development of TerraPreta soils and for the reduction of nitrate leaching into the groundwater. By using biochar, you achieve a permanent CO2 sink in the sense of the Framework Convention on Climate Change, Art. 1 para. 8, and make a positive contribution to climate change.
Activated carbon applications in the field of air pollution control and water filtration
Activated carbon from biochar provides excellent results in air pollution control and water filtration. Biochar is a full substitute for lignite-based activated carbon, which is still widely used today. However, with a significantly better CO2 balance.
As insulating material and for humidity regulation in the construction industry
Biochar has an extremely low thermal conductivity and can absorb up to six times its own weight in water. Due to these properties, biochar is ideal for insulating and regulating humidity in buildings. In combination with clay, lime mortar and cement mortar, biochar can be added to the sand at up to 50% by volume. This results in excellent insulating, breathable interior plasters, which keep the humidity of the rooms in the ideal range of 45-70% both in summer and winter. This prevents dry room air, which leads to respiratory diseases and allergies, and also prevents air condensing on the outer walls, which leads to the formation of mould.
Also in the outside area biochar spray plasters can be sprayed instead of polystyrene up to 20cm thick. By this way the houses become carbon sinks due to their insulation and at the same time have a healthier room climate. If the houses are demolished one day, the biochar clay plaster can be used directly as a valuable compost aggregate. The biochar clay plasters adsorb odours and toxins, which not only improves the indoor air for smokers. In addition to use in residential buildings, biochar clay plasters are also particularly suitable for warehouse, industrial and stable buildings as well as for schools and other rooms, where many people frequently spend time.

The pharmaceutical industry has great potential for the acceptance of biochar. The main applications are charcoal tablets against diarrhoea and for detoxification, as well as their use as carriers for active pharmaceutical ingredients. Biochar is also used in creams and soaps and as a dye.
