The leading clean­tech company for a sustainable use of resources



We follow the maxim:
There are no resi­dues, only valu­able materials.

That is why we work first and fore­most to find forward-thin­king solu­tions. Toge­ther with various univer­si­ties and rese­arch insti­tutes we  develop new ways for a sustainable use of exis­ting resources.

Conti­nuous inno­va­tions and further deve­lo­p­ments make us a pioneer in our industry. As a clean­tech company for plant engi­nee­ring and envi­ron­mental tech­no­logy based in Germany, we have been designing and manu­fac­tu­ring certi­fied, high quality carbo­niz­a­tion plants for more than 10 years. What’s more, our tech­no­logy meets the highest envi­ron­mental stan­dards. We are a global market leader in the field of phos­phorus recy­cling from sewage sludge and the produc­tion of high quality biochar.

Carbo­niz­a­tion drives sustaina­bi­lity
and enables circularity

Upcy­cling is a process of trans­forming waste mate­rials into products of a better quality or for
better envirnon­mental value.
Using PYREG Tech­no­logy, compa­nies address the end-of-life concerns related to their products, trans­forming their waste into value added products, such as energy and biochar.
