Value proposition

High profitability

  • Low investment
  • Fast payback time
  • Short project delivery time
  • Energy effective and low operational cost 
  • Low maintenance cost 
  • Hydrogen consumption in accordance with the theoretical minimum 
  • All inputs are consumed or can be reused
  • Possibility of creating a highly automated solution 
  • No exposure to, or costs related to emission rights 


  • Zero CO2 emissions
  • Only water and reduced metall as output 
  • Enabling efficient recycling of waste and residual products such as oxidized scale and grinding swarf  
  • Smallscale solution enables locally placed furnacesthus reducing transport and handling costs 
  • GreenIrons process is energy effective 
  • A Duo furnace further improves the energy efficiency
  • With our sustainable hydrogen partners the GreenIron solution can be CO2 negative and the total energy cost of running the process can be cut by ca 80%  
  • Enabling drastic reduction of waste in landfills while recapturing valuable commodities


  • Small scale allows for local establishment 
  • Flexible with regard to input materials and volume to be processed per cycle
  • Modular and scalable 
  • Solution can be tailor made on site 
  • Can produce unique material compositions in variable amounts with ease 
  • Multiple methods to produce hydrogen creates flexibility with regard to energy needed and local conditions (e.g. electrolysis, biomass or plastics/rubber as hydrogen base)  

The optimal solution to recapture valuable commodities from residue and waste from the mining-, steel and manufacturing industry.
