Carbon Dioxide (or ‘CO2’) is a natural by-product of burning fossil fuels. A lot of people have become aware of this carbon problem, and so Carbon Capture has become an area of growing interest. There are many Carbon Dioxide emission trading schemes currently in place around the world. However, some Carbon Dioxide is ‘locked’ in the soil in the forms of seeped organic matter – the stuff that plants and animals live off. This article will discuss some of the biologies behind Carbon Capture, and how this is used to enhance agricultural productivity around the world.
Carbon Dioxide is locked in the soil in the form of seeped organic matter – the stuff that plants and animals live off. This is responsible for the loss of much of the globally essential Carbon Cycle. Carbon Dioxide is a major contributor to climate change. The Carbon Dioxide is removed from the soil by the carbon sequestering bacteria using organic matter as their source. As the bacteria decompose the Carbon Dioxide, they release oxygen, and the oxygen becomes part of the soil. This process of Carbon Capture Engineering benefits the overall ecosystem services.
Capture carbon dioxide in urban soils
This is perhaps the most well-known way to capture carbon dioxide in urban soils. In this process, a carbon filter cartridge is placed in the reservoir where the water is coming from, with holes at the bottom to let the carbon dioxide gas out, and holes at the top to let the air in. When rainwater passes over the carbon filter, the water traps some of the dissolved CO2, and the trapped CO2 then reacts with the bacteria in the reservoir to produce oxygen. Now all that is needed is that the captured carbon must be returned to the wetland. This is a recycling process.
Urban soils are generally heavy with organic material. To make up for the lost organic matter, two methods can be used to solve the problem. One of these is called soil carbon sequestering. Carbon sequestering is a major tool in urban soils management because it is a means to replace some of the lost organic carbon from the carbon dioxide absorption process in the reservoir.
This is done by way of dolerite fines. Dolerite fines are a type of organic matter that is effective in reducing carbon dioxide absorption from soils. They are created from clay that is similar to the conditions that exist in the reservoir. They contain high levels of carbon and have a high capacity to lock in moisture. Carbon sequestering can thus result in a long-term cycle of protection of soils that can reduce or even eliminate soil erosion and water loss.
Carbon sequestering can occur in urban green spaces. This means that it can also occur in agricultural lands that are not classified as conservation areas. In most cases, carbon-sequestering in these types of lands will not require any additional treatment. However, this does not mean that it can not occur. If the carbon capture and storage technology used to place the co2 in the soils of agricultural lands is less advanced than used for urban soils, that will also limit the extent of potential effects in the urban environment. In most cases, the effects will be less severe than those in agricultural lands.
Protect natural ecosystems
There are still several unknowns regarding the field of Carbon Capture Engineering and how it is being deployed to protect natural ecosystems. A lot of studies have been initiated to understand how carbonation and climate change affect ecosystems. Carbon Capture Engineering could have an impact on how we manage natural ecosystems. Carbon Capture Engineering is still at an early stage of development, and there is still much that needs to be learned and understood. However, some aspects of Carbon Capture Technology are already being deployed in agricultural land management and flood mitigation to protect ecosystems from climate change and increasing water risks.
Carbon capture technologies
Some carbon capture technologies currently under research include Carbon Sequestration from active transport systems, carbon cycling from soils, carbon granular activated transport (gravels), and carbon adsorption from urban soils. With the current dearth of knowledge about the efficiency of these technologies and their effects on natural ecosystems, these Carbon Capture Engineering projects are not yet serving to protect natural ecosystems. It is expected that these research projects can improve the efficiency of these technologies and increase their effectiveness in the protection of ecosystems and the reduction of environmental pollution.
