From Brazilian sugar fields to the Etea Estates in India, crushed rock is sprayed across large farmlands worldwide in favel to bid.
This method is called Enhanced Rock Weathing
It can be a large business with tech giants, airplanes and fast fashion firms to buy carbon credits from ERW projects to “remove emuts.
– What is ERW? –
ERW aims to reduce the natural process called Webility.
The WEASTING is a deterioration of rocks with carbonic acid, which builds where carbon dioxide is in the air or soil reduces in the waters.
Weathering occurs naturally when the rain falls on the rocks, and the process can lock the mildew or the ground as a bicarbonate, and finally limestone.
ERW accelerates the process that uses quick rocks such as basalt is the best to increase their surface.
– How effective? –
ERW is still a new technology and there are questions for how much carbon is.
One American lesson found using 50 tons of foundation to the world’s hectares annually can remove 10.5 tons of carbon dioxide with four hectare.
But scientists use basalts in oil palm fields in Malaysia and model in Australia and measured low-removal prices.
“The temptations in the field show that there has been an exaggeration and allowed to be arrested,” said Paul Nelson, a soil of James Cook University.
Values depending on converting Rock and size, weather is wet and how hot, soil type and land management.
And rating carbon is difficult.
The most popular process of “nations”, well-released ions are taken from the rock during the weather.
But those areas are produced regardless of how rock seated.
“If there are acids stronger than carbican, then they will respond to those,” Nelson said, the measurement institutions are produced even when Carbon Dioxide can be taken captive.
That does not mean that ERW does not mind, says Wolram buses, researcher from the Carbon dioxide buses in Australian National University, that requires careful balance and measured.
“There is no doubt that this method is working,” he said.
“However, to make sure how much the carbon dioxide is required to make basic lessons.”
– Are there other benefits? –
Additional rock increases alkality of soil, which can increase the growth of plants, soil nutrients and soil format.
Basalt has been naturally and is often found such as the passing passage, reducing the cost of the process.
Experts notice that no matter the rock meets other acids in the ground, it fails to lock Milbo Dioxide in that section, there may still be benefits of planet.
That is because acids in the soil will eventually bathe in rivers and sea, where acidization leads to carbon diapers.
If the rock is neutral acid on the ground, “he blocked out carbon dioxide from the water that entered the bottom at the bottom-at-door”, Nelson said.
The scales of those non-banned “are not clearly” are unclear, anyway.
– What are the risks? –
The ERW is considered a safe consideration because it is just speeding up the environmental process. However, some quick rocks of weather have high levels of toxic metal.
Spreading the Rock of the World and requires the appropriate protection gear for those involved.
But a great risk is that the wrong measures are enough carbon caught.
Other projects already sell carbon credits from ERW. If the company buys ERW debt to “remove” its outgoing but a hosting process is under consideration, it may result in the higher higher carbon dioxide inserted into space.
– Where is it held? –
Projects are happening in many parts of the world, including Europe, North America, Latin America and Asia.
Earlier this year, the project in Brazil announced that the first credits had been guaranteed by the certified carbon-removable from the ERW project.
This process is used or struggled with agricultural settings from Tea’s Tea’s Tea’s Darjiev to US and Maize fields.
– Which investor is interested? –
ERW Start – M Carbon, working in India – won $ 50 million $ 50 million projects for removing carbages from the beginning.
In December, Google declared what was the real ERW ERW country, 200,000 tons of carbon removal credits, will be submitted at the beginning of 2030s with the Startup Terradot.
The cost of the agreement is not disclosed but a different agreement made by the Terradot with a company representing the company including 90,000 tons of $ 27 million.
