From pollutants to products: from consumer products that capture carbon

We have poured So much carbon Emission reduction alone is not enough to prevent the effects of climate change.Isolation must be part of the solution, but we can’t Plant enough treesTherefore, some people start to be creative, using circular design principles to create new products from our biggest problem waste. Earth911 publisher Mitch Ratcliffe recently published a report titled “Mining sky: Use the captured carbon to make consumer goods. “Here, let’s take a look at some consumer products that these companies and other companies make from the captured carbon.

Direct air capture

Direct air capture (DAC) Use chemicals to remove carbon dioxide from the air, basically to concentrate it.There are two DAC system type; One uses liquid solvents and the other uses solid adsorbents (such as chemical sponges). Once carbon dioxide is captured from the atmosphere, the solution (or adsorbent) is usually heated to release the carbon for use, while other chemicals are used in another carbon capture cycle.

The climate change benefits of DAC depend on two factors- Source of energy Used in the carbon capture process and the storage of the captured carbon. The use of fossil fuel-based electricity in the DAC process can impair its effectiveness. The heat used for DAC must come from waste heat, renewable energy or nuclear energy to significantly reduce atmospheric carbon.

When the captured carbon is used to make consumer products, the life of the product will determine how long the carbon stays in the atmosphere.Disposable products and consumables (such as Carbonated drinks) Will quickly release carbon back into the atmosphere, and building materials may store carbon for decades.

The first large-scale DAC factory Currently under development in the United States, most of the 19 DAC plants already operating in Europe, the United States, and Canada are small in scale and sell the captured carbon for use Products and business processes. More and more companies are collecting carbon from industrial emissions at the source. This is because the concentration of carbon in industrial chimneys is much higher than in the atmosphere.

specific

One of the earliest and most promising consumer applications of capturing carbon is specific. A durable material for Huge number, It is said that the concrete is also responsible 4% to 8% Half of the world’s carbon dioxide comes from production processes.Using captured carbon in concrete can not only help offset the energy costs of producing concrete Up to 48%, But it can also reduce the energy cost of capturing carbon by skipping energy-intensive purification steps.

Cleaning products

The service life of cleaning products is completely different from the service life of concrete. However, when you clean the house, there is a satisfactory balance in purifying the air.A sort of New laundry capsule The surfactants used by Unilever are made from alcohol from captured industrial emissions. Although this new type of washing powder will only be available in China at first, it may eventually become the choice of everyone looking for washing powder. Greener and cleaner In their washing machine.

Expedition Aviation It started as the consumer products division of a company that produced carbon dioxide-enhancing additives for concrete and anti-corrosion coatings. Now, they cooperate with other companies to produce a variety of products. Each product uses materials made from carbon dioxide emissions and replaces the more carbon-intensive materials used in traditional products.Including CleanO2, A series of soaps made from potassium carbonate captured from natural gas heating equipment.

household products

Expedition Air’s partners also produce a variety of household products, from Concrete coaster arrive crayon. Few of these products are likely to make a significant contribution to carbon sequestration. Instead, they act as the initiator of the conversation. For this reason, nothing is more effective than art. Air art It is a program where Expedition Air collaborates with artists through residency programs and other partnerships to showcase carbon capture technology. From science-themed T-shirts to colorful landscape paintings, every Air Art work tells an environmental story. They also use materials that contain captured carbon.

Luxury

At least one company is turning alcohol made from captured carbon into a more luxurious use than laundry. airlineIt may be ironic to use captured industrial carbon to make jet fuel. But their products also include pure alcohol, which forms the basis of unisex perfumes. Air eau de toilette, With jasmine, fig and tobacco flavors. (Although there are pure essential oil fragrances, almost all commercial perfumes use an alcohol base. Alcohol is one of the least problematic ingredients used in perfumes. Cologne.) Air Company also produced an 80-proof Vodka.

Perhaps the ultimate luxury, diamonds are pure carbon.They are usually the least Ethical jewelry Options.even Lab-grown diamondsCompared with mined diamonds, it has less impact on the environment and humans and has a huge carbon footprint because they are made of methane and require huge energy to produce. Ether diamond By using DAC carbon as a raw material and renewable energy to power its process, it improves the diamonds grown in standard laboratories. Each carat produced can remove 20 metric tons (22 US tons) of carbon dioxide from the atmosphere.

Air carbon

Manufactured in a facility powered by renewable energy, AirCarbon is a plastic alternative. Using air and carbon dissolved in water, this plastic-like material does not require DAC. Instead, the manufacturer of AirCarbon uses biological processes. In a large saltwater pool, natural microorganisms from the ocean form a polyester material called polyhydroxybutyrate (PHB). They made compostable straws and tableware from the resulting plastic-like materials. recoverAlthough disposable products like this are of little value in terms of carbon sequestration, their replacement of disposable plastics is still a major victory. Ocean.

As new DAC facilities come online and increase the capabilities of the technology, the cost of carbon capture will decrease. As the scale of carbon capture expands, the number and types of consumer products that capture carbon will change. This product category can be transformed from a novel product that sparked a topic to one of many strategies for drastically reducing atmospheric carbon concentrations.
