The currently most promising possibility to use biochar in agriculture in an economically and ecologically beneficial way is by cascade use in animal husbandry. This is the conclusion reached by the authors Schmidt, Kammann and Gerlach in their book…
Swiss farmers have been testing biochar for litter and as a feed additive for years. The experiments will be scientifically monitored within the framework of the international project “Carbofeet”. Biochar is used there as a feed material for regulating digestion and preventing…
The study was published in 2011 and provides an overview of the various processes used to produce biochar (pyrolysis process) and biochar (hydrothermal carbonisation) for soil application. The focus is on technological, economic and climate-relevant…
Already today, almost 70 % of renewable energies in Germany are generated from biomass. However, at around 300 g CO2 / kWh, electricity from biogas from conventional corn monocultures is only slightly better than the conversion of fossil…
Urban trees are indispensable for healthy air in cities. However, they are also exposed to special stress factors and therefore have significantly shorter lifespans and higher maintenance costs. For this reason, the Swedish capital Stockholm has been…
Various international studies prove an increased gas yield through the addition of biochar to the biogas process. With approx. 9,200 biogas plants (Statista 2018), Germany in particular offers great potential for optimisation. The study investigates which…
In recent years, the terra preta (black earth) phenomenon has aroused increasing interest. These are man-made soils discovered in the middle of tropical rainforests that are up to 3000 years old, with high nutrient and organic matter in the soil…
Biochar as a growth medium and as a substitute for peat: The authors and scientists Steiner and Hartung have tested this in a study (“Biochar as a growing media additive and peat substitute, Solid Earth 2014). Because peat…
In the Canadian province of Quebec, plant coal has been used as a substitute for peat and perlite in reforestation projects for the rearing of tree seedlings for some time. There are two reasons for this. On the one hand, prices for conventional planting…
