Syn-Lime – Synthetic Limestone [Carbon Sequestration 101] This carbon dioxide removal technology is spearheaded by Blue Planet. 70% of the aggregate used in concrete is already limestone. The process captures carbon dioxide emissions from bioenergy, natural gas and coal-fired power plants, steel mills, cement plants and … Air pollution from burning fossil fuels kills over 1 million people per year and is the primary cause of climate change. Management. of embodied CO2 mainly from manufacturing the portland cement component of the cubic yard. As a result Blue Planet’s capture method is extremely efficient, and results in a lower cost than traditional methods of CO2 capture. Each ton of CO2-sequestered limestone traps 440 kilograms of carbon dioxide, preventing it from accumulating in the atmosphere. But do you know how much? When the “spent” capture solution reacts with the Geomass, reforming it, these metal ions are released and combined with the carbonate solution to form the carbonate mineral coating. The aggregate can be produced in different sizes, ranging from sand-sized to gravel-sized. Send us an email: firstname.lastname@example.org Blue Planet Systems Corporation is a cleantech startup company located in Los Gatos, California, that is developing technology, products and services related to economically sustainable carbon capture and mineralization, whereby carbon dioxide is permanently sequestered in building materials for beneficial reuse, specifically as aggregate for concrete. The carbonate minerals form a synthetic limestone coating. High-Value Building Materials, LCP™ is a Scientific The Blue (Plastic) Planet. New processes and scalable systems like theirs are instrumental components of reducing the impact we have on our planet.”. Photographs show the placement of Blue Planet’s concrete at SFO. Unique, Efficient & Low-cost Carbon Capture Method. Balance of Aggregate Demand and Anthropogenic CO2. A rock particle is coated with our synthetic limestone, forming a carbon-sequestering coating that is 44% by mass CO2.The coating can contain residual fine particles from the capture solution regeneration. That’s because purification of CO2 requires vast amounts of energy, taking away from our objective of a net reduction in CO2. Blue Planet has developed a carbon capture and utilization system that permanently removes carbon dioxide and transforms it into synthetic limestone. If a cubic yard of concrete uses 600 lbs of cement, its CarbonStar rating is 600. Carbon Negative Building Upcycled Aggregate is a by-product of demolished and returned concrete that has been through a calcium extraction process for Blue Planet’s carbon dioxide sequestered limestone. This market is growing at a rate around 8% per year. This aggregate is useful in most concrete mixes, and is well indurated and harder than virgin aggregates due to the uniform process of Blue Planet’s reformation step. On a mass basis, concrete is the most recycled material on Earth. Of the three components in concrete – water, cement and aggregate – cement is the most significant contributor to CO2 emissions. Check out BPN's online hydroponic nutrient store and buy directly from the manufacturer. Unlike other carbon capture methods that require an energy-intensive carbon dioxide purification step for liquification, transport and injection, the Blue Planet system directly converts the carbon dioxide diluted in flue gas to carbonate, which avoids significant costs and parasitic loads of purifying the carbon dioxide gas from a dilute stream in order to liquify it for underground disposal. For example, the CarbonStar rating of the carbon-negative mix design discussed above is -1920, or about one ton carbon negative per cubic yard. This approach would also save enormous transportation costs and carbon footprint. Instead, the synthetic limestone rock produced is distributed to concrete plants for incorporation in concrete, where the carbon dioxide is stored permanently. “I am pleased to support the continued dedication and innovation at Blue Planet in our shared push for a more sustainable future. The use of Blue Planet aggregate is the most effective way to achieve carbon neutral – or even carbon negative – concrete. Concrete testing showed that Blue Planet’s concrete met all necessary specifications. All Rights Reserved. Approximately 50 billion tons (50 Gigatons) of rock is mined every year worldwide for use in concrete, asphalt, and road base. Blue Planet Nutrients, The Professional's Choice. The Blue Planet System directly converts CO2 to carbonate for mineralization as a synthetic limestone (graphic courtesy Blue Planet Systems). CO2 sources include flue gases from bioenergy plants, natural gas and coal-fired power plants, steel mills, cement plants, and refineries, as well as directly from the atmosphere – direct air capture (DAC). The company’s first commercial plant is being constructed at Pittsburg..To read the rest of this article, please … Most aggregate on a worldwide basis is purchased by governments, or for government-funded projects. carbon footprint of the portland cement in the mix doesn’t come into the calculation. Additionally, specific comparative mix designs can be simply and quantitatively compared using the CarbonStar rating which plainly shows the consequences of different proportions of aggregate and cement of the mix designs of interest. Precise values are determined applying LifeCycle Carbon Analyses (LCA), that incorporate the auxiliary load carbon footprint of Blue Planet’s processes and transportation at specific plant locations and CO2 emission industry-specific types. With David Attenborough, Peter Drost, Roger Horrocks, Roger Munns. Blue Planet carbon sequestration plants produce coarse and fine aggregate made from sequestered CO2 utilizing the carbon mineralization process. The difference being that Blue Planet aggregate contains sequestered CO2, which when used in place of traditional aggregate, reduces CO2 in concrete. Thus the total offset is 1320 lb.s industrial or atmospheric CO2 sequestered in aggregate + 600 lb.s captured from the production of portland cement, totaling 1320 + 600 = 1920 lb.s CO2 offset, or nearly one ton CO2 (2000 lb.s) captured and incorporated per cubic yard of concrete. Sources: Blue Planet Systems Corp., Los Gatos, Calif.; CP staff. Blue Planet and Kamine Development have partnered to develop a concrete-grade, synthetic limestone that could offset carbon dioxide emissions associated with portland cement production. Solving the Carbon Capture Rather than have CO2 excess gas from industry be let into the air, it’s captured from the air or industrial exhaust and then turned into a carbonate in solution. The transportation and product delivery infrastructure for delivering Blue Planet’s carbon sequestered aggregate is already in place in every country and at every site in the world that is producing concrete, asphalt and road base. Typically if it is not landfilled, it is broken up and recycled for a low value use – such as a road base. The plants can be financed, owned and operated under well-established project financing structures without subsidies. Blue Planet’s first plant is being constructed in California, adjacent to a natural gas-fired power plant and the Sacramento Delta, for barged material transport of raw materials and finished goods. A $10 million funding round positions Blue Planet to advance a carbon capture and utilization system netting concrete-grade synthetic limestone. This differentiates Blue Planet from most CO2 capture methods because the captured CO2 does not require a purification step, which is an energy and capital intensive process. In strength, performance and cost, Blue Planet CO2-Sequesterd Aggregate is equivalent to that of standard quarried aggregates. Blue Planet uses this recycled concrete in its remediation process as a means of obtaining calcium and alkalinity. But because Blue Planet denudes it of its weakened crushed components, it is now upcycled to the equivalent regular aggregate. Governments have the procurement power to specify carbon-sequestered rock in construction projects, providing what may be the strongest lever we have world-wide to prevent CO2 from entering Earth’s atmosphere. Blue Planet provides a unique solution to the global carbon capture problem. Blue Planet’s limestone-coated light weight aggregate was specified in Interim Boarding Area B at San Francisco International Airport where it was included in the concrete poured in 2016 by Central Concrete.
