Our patented technology is called Direct Carbon Immobilization or DCI™.
DCI™ is a thermochemical separation technology which is designed to process mixed waste and biomass to produce syngas and cleaned solids.
DCI™ is gasification, a process which is in operation for over 100 years like in coke making, of solid waste in a relatively slow and stable process. The slow vertical speed within the reactor limits mechanical abrasion and guarantees complete conversion of hydro carbons in gas and solid carbon.
The gas is heated up further to ensure decomposition of complex hydrocarbons like PAH’s, dioxins and PFAS and results in the production of syngas.
Agglomeration of the solids is little to none due to avoiding melting temperatures of slags.
All this is done in the same reactor.
To convey the maturity our innovation we refer to the Technology Readiness Level system, which has steps 1 to 9.
TRL 1 and 2 were covered by our literature study and patent.
TRL 3 was covered during laboratory testing.
TRL 4, 5 & 6 will be reached in our pilot called Lab Scale Reactor for DCI™ with a capacity of 5-15 kg/d.
TRL 7 & 8 will be reached in a demonstration plant which will have a capacity of 100-200 kg/h and is part of a 24/7 operating facility.
TRL 9, let’s see
This is where we will post updates as we continue our journey.
Expected in Q4 2023: off gas cleaning facility for the LSR. From that moment on the range of feed material for the LSR is expanded to ones containing halogens and volatile metals. Processing complex waste will result in reaching TRL6.
Q3: 2023: Operations with the LSR have become standardized. Successfully processed simulated waste and ‘safe’ real waste, TRL 5 has been reached.
A literal screenshot of the screen from our gas analyser. The balance is nitrogen. We were pretty happy with this result.
Update on this picture in Q4 2023. We changed the gas analyser set-up since posting the picture above and discovered that the lack of CO2 measured at the time was probably caused by the filter in front of the analyser. CO2 is produced in the process and its has been measuring since the changes. We will update with a picture from a test in the period of week 47 to 48 of 2023.
Q2 2023: The report about TRL 4 is ready and has been distributed to its sponsors
Q2 2023: Commissioning of the LSR, very close to a flawless start-up!
A view inside the empty shaft in which feedstock is charged during commissioning.
The LSR ready for trial runs and saying good bye to our now expert in sewage sludge carbon.
Q1 2023: DOPS Recycling Technologies welcomed the first university student. She did a research project on the carbon produced with the DCI™ technology with sewage sludge as feedstock. The outcome of the quality of the activated carbon was very promising.
Q4 2022: The report about TRL 3 is ready and has been distributed to it’s sponsors.
Our minimal viable product, it wasn’t for sale though….
