premium carbo­niz­a­tion tech­no­logy for a valu­able busi­ness proposition

As biochar pioneer, we have been setting stan­dards in decar­bo­niz­a­tion and sustaina­bi­lity with our patented tech­no­logy for over a decade

The latest genera­tion:
The Pyreg PX

Our plants are indi­vi­du­ally custo­mized to your needs. No matter whether 500 or 1,500 kW fuel capa­city. Each system contains compact, decen­tra­lized carbo­niz­a­tion tech­no­logy that can be easily inte­grated into an exis­ting infra­st­ruc­ture and your mate­rial cycles. The biomass or sludge is not inci­ne­rated, but rather gently degassed and then carbo­nized at tempe­ra­tures between 500 and 750 °C – in an oxygen-limited process. The clean, rene­wable thermal energy from a PYREG system, provides up to 5 million kWh per year.

advan­tages of our technology

multi-mate­rial capability

The PYREG process is suitable for a wide range of carbo­naceous inputs. Exem­plary are: Digestate, manure, dry manure, grain waste, clean-out, husks, silage waste, slaugh­ter­house waste, hay, straw, wood chips, SRC wood, green waste, fruit stones, nut shells, compost scree­nings, pomace, spent rubber, scrap tires, storm damage, wear parts, fabric/cotton, lobby waste, paper, card­board, paint resi­dues and many more.

continous and safe process

  • State-of-the-art auto­ma­tion and control technology
  • Future­proof data acqui­si­tion and processing
  • > 99 % elimi­na­tion of fine dust in exhaust gas due to special process gas filter
  • Meets EU emis­sion limits


Only the PYREG process allows such precise control of the carbo­niz­a­tion para­me­ters; there­fore, carbon products can be produced in diffe­rent quality grades, ensu­ring that raw mate­rials, such as phos­phorus, can be gently recy­cled.
At the same time, organic-based pollut­ants (such as solvents and micro­plastics) are virtually elimi­nated and mineral-based pollut­ants are filtered out at tempe­ra­tures of up to 1000°C in the combus­tion chamber. Effi­cient, climate-friendly and without harmful by-products.

varia­bi­lity in heat deli­very systems

  • Maximum varia­bi­lity in heat extrac­tion: Hot water, steam, thermal oil
  • 5 GWhth usable rene­wable heat energy per year

Compa­ring the diffe­rent models

PYREG systems set inter­na­tional stan­dards for quality and tech­no­logy and are reco­gnized by the US Envi­ron­mental Protec­tion Agency (EPA). The bene­fits for both systems are iden­tical (PX 500 & PX 1500). They only vary in perfor­mance and specifications.

State-of-the-art Auto­ma­tion

  • Future-proof data acqui­si­tion and proces­sing with Siemens IOT
  • Remote main­ten­ance and control systems for maximum opera­tional reliability

CO₂-reduc­tion that pays off

PYREG custo­mers have the oppor­tu­nity to mone­tize the carbon removal acti­vity of their biochar produc­tion on various market­places. This is because biochar is a reco­gnized carbon removal tech­no­logy that is urgently needed to meet our global climate goals. For example, the plat­form helps corpo­rate buyers create a long-term sourcing port­folio to neutra­lize their CO₂ foot­print and achieve NetZero with CO₂ removal certi­fi­cates (CORCs).
