Permanent Carbon Capture
TECHNOLOGY
Our paradigm-shifting geomimetic mineralization technology uses CO2 from any source as a feedstock to create carbon-negative aggregate.
Blue Planet technology combines waste carbon dioxide with calcium sourced from waste, to manufacture synthetic limestone aggregate.
-
CO2 is safely and permanently stored in aggregate
-
Process is Geomimetic®, meaning that it mimics the earth’s natural process of creating carbonate rocks or limestone
-
The calcium source, referred to as Geomass, can be a range of materials:
-
Demolished/Returned Concrete
-
Cement Kiln Dust
-
Steel Slag
-
Fly Ash / APCr
-
Bauxite Residue
-
Silicate Rocks
-
A Circular Solution
-
Only inputs are waste; waste concrete and CO2
-
Waste concrete is used as source of alkalinity and calcium but also results in a byproduct of Upcycled RCA.
-
Upcycled RCA can be used in structural concrete and at a higher replacement than of virgin aggregate than regular RCA
-
CO2 capture solution is refreshed by exposure to geomass so consumption of chemicals is negligible and there is no process waste
-
For alternative geomass (steel slag, cement kiln dust) the Blue Planet process can produce a valuable byproduct such as SCM as well as valorizing what are often hazardous wastes.
THE SCIENCE
BLUE PLANET ADVANTAGE
CO2 from any Source
-
The Blue Planet process can work with CO2 from any source including:
-
Cement plants
-
Iron and Steel plants
-
Natural Gas power stations
-
Refineries
-
Direct Air Capture
-
Hydrogen/SMR
-
-
CO2 does not need to be purified or liquified, Blue Planet is able to utilize flue gas directly as well as pure CO2 from DAC or process streams.
-
Has been demonstrated on gas streams containing as little as 5% CO2.
Cost-Effective
-
Commercialization of end products turns CO2 capture and sequestration from a cost to a profit center
-
Cost of both CO2 and Geomass inputs anticipated to be negative in markets with CO2 pricing and gate fee for industrial waste Geomass
-
Blue Planet technology is cheaper than a typical Post-combustion CCS project. No purifying, liquefying and or transport of CO2
-
By producing high value, high volume products Blue Planet's technology makes carbon capture and storage profitable without relying on a price for carbon.
CO2 is stored Permanently
-
While other carbon capture methods may store CO2 temporarily, the Blue Planet carbon storage is permanent - as in, forever.
-
Nature based capture solutions such as afforestation can be useful but the sequestration of CO2 is not permanent as land use could change or disease could wipe the trees out.
-
With Blue Planet's method, even once the building reaches the end of it's life and is demolished the CO2 will remain locked up as a mineral in the aggregate .
