01 / Our conviction
Technology is not packaged propaganda.
It is a guarantee made of mechanical structure, thermal logic, process testing and long-term operation. Olten wants to be the long-term technical guardian of every project.
-
Continuous operation
Sealing, gas circuits, cooling and control designed together for long-term continuous duty.
-
R&D and manufacturing
Designed around a system-level energy flow, not a single pyrolysis unit.
-
Verifiable credentials
Qualifications, patents, catalogue listings and test data can be checked project by project.
-
Engineering collaboration
A reviewable closed loop from raw material and selection to product and market path.
02 / Six industrial solutions
Six industrial-grade solutions, each with its own engineering boundary.
Each direction is built around specific raw materials, technical routes, product paths and business synergies.

03 / Global market access
More than selling equipment: helping carbon materials reach the market.
With years of market experience, Olten coordinates carbon-material and application networks so customers can distribute activated carbon, biochar, char feedstock, biomass and fuel charcoal, across quality documents, applications, regional channels and project collaboration.
OltenMarket04 / Financial analysis & ROI
Returns must be grounded in continuous operation and real project conditions.
Revenue may come from char products, activated carbon, waste-heat power or process heat, by-products, carbon value and sales channels. It can only be modelled against real site heat data, feedstock, operating hours and agreed boundaries.
What a life-cycle model includes
- 01 Feedstock supply, moisture content, price, transport and pretreatment cost
- 02 Capacity, effective operating hours, yield, calorific value, quality and product path
- 03 Equipment, civil works, energy, utilities, personnel, compliance and maintenance
- 04 Buyers, buyback or distribution channels, inventory, delivery and cash-flow timing
- 05 Uncertainty in carbon methodologies, MRV, registration and market prices
05 / Global carbonization ecosystem
Four specialist sites. One continuous line.
From the machine to the market, every Olten site follows the same material: biomass in, carbon products and verified data out.
- Sheet 02/05 OltenMachine Equipment catalogue: crushing, drying, molding, carbonization and complete production lines, with the OLT-D explained part by part.
- Sheet 03/05 OltenCarbon Biochar and international carbon credits: feedstock traceability, product characterization, dMRV and verification.
- Sheet 04/05 OltenMarket Trade and cooperation portal: materials, RFQs, the B2B trade workflow and the CDR credit workflow.
- Sheet 05/05 OltenTech Technology selection, R&D and knowledge centre, and project ROI modelling.
Open to global cooperation
Regional EPCs, installation and O&M teams, automation providers, raw-material and product channels, investors, laboratories and technical service partners are welcome to join long-term project delivery.
