Remove CO₂


World­wide, we have already installed over 50 plants for our custo­mers since 2009. These PYREG systems remove more than 30,000 metric tons of CO₂ annu­ally and, with 75 GWh, cover the annual heating requi­re­ments of around 5,000 house­holds. Our tech­no­logy is consi­dered a refe­rence by the U.S. Envi­ron­mental Protec­tion Agency and is EBC type-certi­fied (Euro­pean Biochar Certi­fi­cate).


PYREG carbo­niz­a­tions systems provide a circular economy solu­tion – closing the loop by recy­cling resi­dual mate­rials into high-quality biochar and rene­wable energy. If the biochar is added to a perma­nent carbon sink, e.g. in agri­cul­ture, viti­cul­ture or buil­ding mate­rials, the recy­cler can also gene­rate Carbon Credits.


PYREG carbo­niz­a­tion systems are rated at the highest Tech­no­logy Readi­ness Level (TRL) 9. These systems feature a modular design, enab­ling us to deliver and install them, with minimal site requi­re­ments, in just a view days. Our systems can func­tion as stand-alone units, or be combined as a multi-unit installation.


The modular design allows us to set up PYREG systems at the source of the waste stream – close to produc­tion and decen­tra­lized. This is how you can trans­form your produc­tion site, which is produ­cing organic resi­dues, into a Net-Zero-site, which is produ­cing value – no trans­port costs and preven­tion of addi­tional, trans­port-related CO₂-emissions.

Award winning tech­no­logy for climate protection

As the deve­loper and pioneer of this carbo­niz­a­tion tech­no­logy, we are not only the world market leader, but have also received several awards, inclu­ding: Fina­list of the New Energy Chal­lenge 2022, winner of the Watt d’Or 2022, Nominee of the German Sustaina­bi­lity Award 2022 and many more.

One tech­nolgy – many solutions

Produce valu­able Biochar!

Carbo­nize resi­dual mate­rials into Biochar. This enables the perma­nent storage of CO₂. Biochar can be used as a valu­able soil condi­tioner, feed addi­tive or as a compo­nent in buil­ding mate­rials, such as concrete and asphalt.

Closing mate­rial cycles

PYREG systems provide a multi mate­rial capable solu­tion – trans­forming your WASTE (woody resi­dues, rubber, plastics, pack­a­ging, compo­sites, food waste, sewage sludge, manure, digestates, etc.) into VALUE. PYREG enables you to close your mate­rial cycle, decar­bo­nize and drive a circular economy.

Rene­wable energy from your own resources

PYREG carbo­niz­a­tion systems deliver, clean, rene­wable thermal energy – as either hot water/oil, steam or electri­city (via ORC). This thermal energy can be used, for example, in district heating appli­ca­tions, supplying up to 420 house­holds per year.

CO₂-Removal and Carbon Offset credits

The controlled carbo­niz­a­tion of the biogenic resi­dues prevents a large part of the carbon contained in the biomass from esca­ping into the atmo­s­phere. A PYREG plant thereby binds up to 3 t CO₂ per t biochar (with approx. 80% C-content, process-related deduc­tions according to EBC sink not yet consi­dered). If this biochar and the CO₂ bound in it is put into a perma­nent carbon sink as a soil improver or filler, the recy­cler receives carbon offset credits.

How to remove CO₂ from the atmosphere


“Our goal is to provide our custo­mers with a complete, effi­cient and cost-effec­tive solu­tion which conti­nu­ally creates an add value. By inte­gra­ting PYREG tech­no­logy at the respec­tive sites and making addi­tional use of
the bioen­ergy gene­rated, we have achieved this in a sustainable manner.”


“The treat­ment of bioso­lids from sewage sludge to biochar with high nutri­tional value is not only cost effi­cient, but also a sustainable solu­tion to locally trans­form organic streams
into rene­wable energy and biochar. Once used as a phos­phate ferti­lizer in the ground, it helps to improve the envi­ron­mental foot­print by seques­te­ring CO2 for centu­ries. By redu­cing the
waste volume by 90 %, the PYREG tech­no­logy offers a great cost saving.”


“In 2011, we opted for PYREG tech­no­logy because only it could meet the strict limits of the Waste Inci­nera­tion Ordi­nance. As we now know, this was abso­lutely the right decision. This summer we will expand our plant park with a PYREG plant (P1500).”


“Critical, diffi­cult to dispose of and cost-inten­sive indus­trial waste is not only a problem in the Asian region. PYREG plants enable our custo­mers to recycle them in a sustainable way – directly at their site. In addi­tion to enor­mous cost savings, the use of this tech­no­logy also improves the waste balance, which makes it possible to expand the site.”


“I have been working success­fully with PYREG for more than 10 years because their  tech­no­logy allows the use of this natural problem solver.”


“Our custo­mers actively contri­bute to climate
protec­tion, as carbon remains contained in the soil for hund­reds of years (carbon sink). Over the course of time we have put three PYREG plants into opera­tion – what better proof can there be that we stand by our ecolo­gi­cally and econo­mi­c­ally sensible decision?”


“Gentle carbo­niz­a­tion of the resi­dual mate­rials is the basis of our valu­able potting soil. We have chosen PYREG because their many years of scien­tific support and prac­tical expe­ri­ence give us great secu­rity regar­ding our sustainable product quality.”


“As the leading marketer of EBC certi­fied biochar, we invest heavily in applied rese­arch and in the certi­fia­bi­lity of carbon sinks. In order to be able to guarantee our quality promise on a long-term basis, we have been success­fully coope­ra­ting with PYREG from the
very begin­ning. We curr­ently have three PYREG plants in opera­tion and will soon expand our capacities.”

Dr. Elke Selle­ring (sales manager Eliquo Tech­no­lo­gies GmbH)


“How do I treat sewage sludge correctly? This ques­tion is of crucial impor­t­ance for modern waste­water treat­ment. On the one hand, the disposal of sewage sludge incurs high costs. On the other hand, it can be used as a valu­able energy and nutrient resource.
In this context we were looking for a partner and found it in PYREG. Toge­ther we offer the plan­ning and realiz­a­tion of a sustainable sewage sludge utiliz­a­tion concept with inte­gra­tion of our sewage sludge dryer ELODRY®️ and the PYREG®️ carbo­niz­a­tion plant – with inte­grated holistic heat reco­very and utiliz­a­tion concept.
This was imple­mented for the first time 10 years ago at the Linz Unkel waste­water treat­ment plant. This was followed by further projects in which we success­fully coope­rated. Since then, we have been jointly offe­ring custo­mized plant concepts for muni­ci­pa­li­ties as partners.”
