Carbon-neutral lime can be used in the production of cement and the manufacture of burnt lime. In the cement industry, a calcinator can produce carbon-neutral feed for the actual clinkerization process, capturing the CO2 emissions from limestone for reuse.

For the lime industry, we can directly produce a finished product that meets industrial requirements. This product is utilized in various applications such as a slag former in steel production, make-up lime in the pulp mill's alkali cycle, as well as an adjuster for brick industry pH levels and a water purifier.

Carbon-negative carbon dioxide is regular carbon dioxide from which various materials and fuels can be produced by reducing it to carbon monoxide and synthesizing it with green hydrogen into synthetic hydrocarbons.

Carbon negativity is achieved with the lime produced during the process, meaning that throughout the production lifecycle, more carbon dioxide can be removed from the atmosphere than was emitted during product manufacture.

With our methods, the synthetic fuels produced can genuinely remove carbon dioxide from the atmosphere. In other words, the more of these fuels are used, the more carbon dioxide is removed from the atmosphere.

To reduce carbon dioxide, a number of strategies and technologies can be employed. One of these involves the process of calcination, where carbonates are broken down into oxides and carbon dioxide at high temperatures. Specifically, when a carbonate is exposed to high temperatures, it decomposes into an oxide and releases carbon dioxide.

For example, the calcination of calcium carbonate (limestone) produces calcium oxide (lime) and carbon dioxide:

CaCO3 > CaO + CO2

Based on similar principles, carbon dioxide can be further split through thermochemical and catalytic reactions into carbon monoxide and oxygen. This approach enables us to obtain valuable carbon monoxide, which can then be utilized in the production of synthetic hydrocarbons.

CO2 > CO + O

By utilizing this method, we can avoid the traditional water-gas shift reaction, where precious hydrogen is oxidized to produce water, merely to convert carbon dioxide into carbon monoxide. In the water-gas shift reaction:

CO2 + H2 > CO + H2O

Bypassing this RWGS reaction, the valuable hydrogen can be conserved, which is crucial given the increasing demand for hydrogen in various applications.

In summary, converting carbon dioxide into valuable carbon monoxide through these reactions not only helps reduce CO2 levels but also provides a valuable resource for the production of synthetic hydrocarbons, promoting a circular carbon economy.

Nature conservation measures refer to methods aimed at restoring environmental damages and biodiversity loss caused by human activities. Some of the most significant impacts arise from soil acidification and particularly from the acidification and excessive nutrients in water bodies. Such issues have led to problems like oceanic dead zones suffering from oxygen depletion, where only algae thrive and other marine life struggles.

There are methodologies available to mitigate these damages, and this is where carbon-neutral lime plays a pivotal role. It can be used to restore the pH levels of water bodies and bind excess nutrients, phosphorus being one of the most concerning. By enhancing the quality of agricultural soil using lime, nutrient runoff can be reduced. As the soil's pH normalizes, plant growth and crop yields can improve.

CDR stands for Carbon Dioxide Removal, which is the process of extracting carbon dioxide from the atmosphere and storing it permanently. The cycle of lime plays a significant role in this as well. From carbon-neutral lime, bicarbonate or double carbonate can be produced. This means that lime can bind two molecules of carbon dioxide to itself. As a result, this method can sequester twice the amount of carbon dioxide at the end of its life cycle compared to the amount of carbon dioxide released during the production from limestone.
