01

Engineering first

Engineer with 15+ years in waste management and recycling: we understand processes, qualities, permits and plants before we calculate.

02

A network that opens doors

Industry, recyclers, investors and public bodies in Austria and the EU: cooperations form fast, expertise is within reach.

03

Every solution as a business case

Capex, opex, revenues, risks and funding: we calculate what a material stream is worth and what a plant may cost.

04

From idea to infrastructure

Project development through to financing, partnership or equity. We stay on board until the plant is running.

05

Creatively solved, understood by all

Creative approaches combined with a deep understanding of both the technical and the economic side of circular systems. And communication that translates for everyone: from engineering to business, from the lab to the board.

02 — Services

Infrastructure that pays off.

From technical assessment through the business case to a financed plant or partnership. Each service stands on its own and feeds the next.

Primary Raw Materials Are Becoming a Strategic Risk

Why secondary raw materials are the key to resilient supply chains.

China's dominance in critical mineral processing keeps growing, export controls are being systematically expanded, and structural supply gaps loom for copper. At the same time, copper, aluminium and battery recycling show what secondary raw materials can contribute to supply security. The report analyses the data and derives concrete recommendations for companies. English version from page 11.
