Biochar – a negative Emissions Technology (NET)
Biochar – a negative Emissions Technology (NET)
with countless application possibilities
The BESTON Carbonization Technology carbonizes residual materials into pollutant-free, highly porous biochar. Unlike rotting or incineration, this process does not release the carbon contained in the residual materials as CO2, but binds it stably in the biochar and thus removes CO₂ from the atmosphere.
This makes biochar production one of the Negative Emissions Technologies (NET) urgently needed for climate protection. When this biochar is permanently incorporated into so-called carbon sinks (e.g. soil, building materials, asphalt), the sustainable storage of CO2 is successful in the long term.
During this process, carbon is not released into the air as CO2. Instead, it is stability bound in the biochar and thus removed from the atmosphere.
Markets need CO2-reducing products, especially in this time of climate change.
Biochar Applications
Depending on the processing stage, biochar can be used in a wide range of applications:
Biochar –as a feed additive30-80%
Biochar is used in silage, as animal feed, in litter, for manure treatment or as a compost additive. Biochar improves animal health, reduces unpleasant odors, optimizes fertilizer quality and reduces loss of nutrients that are harmful to the climate and the environment.
Increased vitality, feed efficiency, feed intake and weight
Increase in egg production and egg quality in poultry
Biochar –as a soil additive20-30%
An intact humus layer stores nutrients and water as well as large amounts of the greenhouse gas CO2. Biochar facilitates this process. With a surface of 200-500 m² per gram and a high porosity, biochar can absorb up to five times its weight in water and the nutrients contained in it. The “green carbon” remains stable during decomposition and does not rot.
As a result, farmers can improve the quality of soil with biochar, save money for fertilizers and obtain additional credits from emission certificates.
Biochar –as a filling additive20-30%
The possible uses of biochar (pyrolytically produced biomass carbon) are extremely varied. It also has numerous positive effects when used in industrial processes. In the cement industry, biochar can be used as an additive/replacer as well as in the production of building materials.
Last but not least, biochar is beneficial because it substitutes fossil fuels and thus improves the CO2 footprint.

02Cascading use of biochar
The cascading use of biochar in animal husbandry and fertilizer management, where the absorption capacity of biochar plays an important role, is also interesting from an economic point of view.
Stage 1: Silage
At the beginning, biochar is added to the silage, which prevents the formation of mycotoxins. At the same time, pesticides are fixed and the formation of butyric acid is prevented, resulting in cleaner fermentation and a noticeable improvement in feed quality.
Stage 2: Digestive process
The biochar then enters the feed via the silage, enhancing the digestion of the animals. The feed intake is increased, which increases weight. This also reduces the formation of greenhouse gases.
Stage 3: Stable hygiene
Biochar is added to the litter, thus binding the liquid nutrients and reducing ammonia emissions. It helps prevent putrefaction, which in turn improves stable hygiene. After just a few days, unpleasant odors are noticeably reduced. What’s more, stables do not have to be mucked out so often, thus saving time and material.
Stage 4: Liquid manure
Biochar can also be mixed into the liquid manure, which binds volatile nutrients and improves the microbial environment. This reduces nutrient losses, which improves the fertilizing effect of the liquid manure. In addition, the liquid manure becomes almost odorless.
Stage 5: Farmland
After absorption of the manure (solid-liquid separation), the solids are composted together with the stable bedding, which produces valuable black earth, thanks to the high proportion of biochar. The incorporation of this black soil and the stabilized liquid manure into the soil improves the water retention capacity, the filter performance and the aeration of the soil, which results in higher fertility. Soil acidification is prevented and the leaching of fertilizers and pesticides into groundwater is reduced.
03Biochar used in industrial processes
The possible uses of biochar (pyrolytically produced biomass carbon) are extremely varied. It also has numerous positive effects when used in industrial processes. Biochar can be used as an additive/replacer as well as in the production of building materials. The final use of the biochar determines the durability of the carbon sink, an essential requirement for the approved effectiveness of a Negative Emission Technology (NET). For example, for soil applications, a scientifically based annual decay must be assumed. However, if the biochar is used as a sand replacement in concrete, for example, this is not necessary because the biochar cannot oxidize in the absence of air.
