About us


Addryn is a working company by Greenstream Technology Limited, the international sales company for the MCT (Modular Cracking Technology) Waste processor with agents in European countries.

Since MCT does not require previous processing of waste, labour costs and maintenance costs are reduced. The savings per metric ton of waste (1,000 kg) is minimum 15 €

Smoke Pollution From Factories & MCT technology
Different industries across the world use different materials and chemicals to make their product. The energy sector, still mostly, uses coal, a means of generating electricity that is particularly damaging to humans and the environment.

The installation of standard pollution control equipment is expensive. A study by MIT found that it may cost coal power plants € 215,000 to € 330,000 per megawatt to install controls for particulate matter, SO2 and NOx. For a typical coal power plant producing 500 megawatts, it could cost more than € 100 million to install controls at a newly built plant and € 150 million to retrofit an existing facility.

MCT technology solves this problem in a completely different way. On the one hand, smoke pollutions are raw materials for MCT technology, and on the other hand, fuel utilisation, passing through MCT technology, is significantly increasing. Our MCT technology is CE certified and does not exhaust any toxic element.

Our mission

The mission of Addryn and the MCT Waste solutions is to enable:

  • Economically viable, 
  • RIO within 3-5 years,
  • Harmonisation with EU standards,
  • Permanent and final disposal of waste at places where waste is generated and / or where waste is disposed of.


Our solution

Our technology is a closed circular system, it maximizes the overall thermal potential of the gases produced in the process to produce pure heat, distilled water, clean CO2 and an inert residue.
The created heat is used to create steam and start steam turbines for the production of electricity, heating and cooling.

Our team

The team has several players:

  • The constructors of the MCT Waste processing solution in Germany and Austria

The European sales team:

  • Greenstream Technology Ltd
  • Addryn agents in Europe:

ES - asier@addryn.eu

UK - martin@addryn.eu
NL/PO - thomas@addryn.eu
Rest EU - harry@addryn.eu



Based on previous great cooperative work, the MCT technology became one of the leading environmental technology developers. 


It is now able to offer the best in the world environmental technical solutions in a very broad application within an objective international comparison. 






The innovative and patented technology, based on 40 years of research and development, offers both technically and economically most effective solutions in the treatment and disposal of various municipal and industrial waste.


The approved and multiple award-winning process is a low-temperature pyro-catalysis in combination with a catalytic-adsorptive after treatment of post-pyrolytic gases and thermal energy recovery. Due to the absence of classical combustion (pyrolysis), no dangerous and polluting by-products such as nitrogen oxides (NOx), dioxins, furans, CO, methane and others are created. 


We can demonstrate the waste processors working in our brand new demo site in Bratislava, Slovakia from February 2020.
