The preventive pre-treatment environmental actions are safer, faster, better and in all included less costly versus the “end-of-the-pipe” post treatment solutions.

The “3R” novel indirectly heated rotary kiln pyrolysis and torrefaction technology provides carbonization / pyrolysis added value of carboniferous materials.

The goal of the 3R technology is to provide cost efficient and for long term environmentally sustainable carbon refining solution for energetic, agricultural and environmental applications. The main component of the 3R is a specially designed, indirectly fired, patented rotary reactor in which organics in a reductive environment are carbonised. e.g. gas-out and decomposed, in low vacuum (0-50 Pascal) up to the material core temperature 850°C degrees Celsius (1,562°F, degrees Fahrenheit). The carbonization temperature selection is feed material specific and in most cases temperatures between 450°C to 550°C (842°F – 1022°F) is sufficient for high efficient thermal decomposition under vacuum. The flexible operation provides wide range of 25 % to 125 % of nominal capacities. The basic material with <15 w/w % moisture content is introduced directly into the 3R reactor, or optionally pre dried. By control of the carbonization process, different types of pre-defined carbon end products can be produced, as of commercial production demanded schedule. The volatile HAPs are safely removed in the reduced volume of gas-vapor stream and converted to syngas and turned into surplus electric power. The standard industrial scale is from 30,000 m3/year (4 m3/h) continuous throughput capacity and optional larger capacities are available up to 420,000 m3/year (56 m3/h). Both electric fired and gas fired versions are available in full scale industrial design.
