The PYREG - Reactor is used for decentralized, thermal recovery of agricultural and industrial production residues such as green waste, sewage sludge, fermentation residues, manure, pulp, etc. To decentralize the availability and the low energy density of biomass in particular, Pyreg, has developed a plant that avoids a mass flow rate of 200 - 1500 t / a long distance transport to the rendering plant. In the thermal utilization of biomass residues, there are significant differences for the realization of such wood fuels. Particularly in terms of up to 100 times higher ash content, and the much higher levels of nitrogen and chlorine are mentioned. These components are responsible for the formation during the combustion of air pollutants such as NOx and dust. The softening temperature was lower than the formed ash makes a tiered specifically developed combustion technology necessary to prevent slagging, and thus a failure of the continuous furnace to a continuous operation.

Terra Preta - CO2 Sequestration

At the very high probability of global climate change, caused by the growing energy consumption and associated CO2 emissions, there are unfortunately fewer and fewer serious doubts. For this reason, for several decades in addition to the energy saving measures and energy from non-fossil energy sources, another option to reduce atmospheric CO2 content discussed: the capture and subsequent storage of the wastes from energy carbon dioxide. On this issue several technological approaches have been developed, which are however not yet gone beyond due to the still unresolved regulatory and other serious technical problems on a test stage.
In Germany, residues from agriculture to fall and the landscape with an energy content of about 25PJ/year. The majority (over 55%) is currently being utilized more in agriculture, in landscaping or composted. Here are the sequestration offers by the deposition of pyrogenic carbon from biomass in agricultural soils is an interesting alternative. During the pyrolysis, in contrast to burning or natural decay only part of the carbon absorbed by the biomass2 re-emitted into the atmosphere. The Biochar obtained as a residue of the carbon Pyreg method provides scientific and technical use of untapped potential. Due to the large nutrient storage capacity of the porous pyrogenic carbon particles (of the Biochar) they can prevent the rapid leaching of nutrients from the soil and fertilized hereby be improved, to provide nutrients for plants. Furthermore, the soil respiration, microbial biomass is significantly improved, together with population growth and efficiency of soil microbes. In laboratory and field experiments, the suitability of the carbon produced by the pyrolysis Pyreg reactor in combination with fertilizer application to soil improvement has been ongoing for several years and continues to show significant benefits in crop yield, for example and in all the important pre-selected range of tests and observations that are thought to be relevant.
The soil could store it globally year to 9.5 billion tons of carbon. This form of CO2 global sequestration could be stored on agricultural land twice the amount of harmful greenhouse gas that is currently emitted by the combustion of all fossil fuels.
The storage of Biochar in soil provides a stable carbon pool and this gives effective carbon sequestration over long periods of time (residence time in the soil ≈ 3000 years) is possible.
By using the Pyreg technology each 1t tonne of organic waste (Biomass) that is pyrolysed into high quality Biochar and used as a soil amendment, means that about 1 tonne of CO2 is removed from the atmosphere and permanently stored in the soil. This represents approximately 27% of the plant in the growth of CO2 bound mass or a carbon-efficiency of over 60%.
