Verde's Products Remove Carbon Dioxide From the Air

2023-07-19 / @GlobeNewswire


SINGAPORE, July 19, 2023 (GLOBE NEWSWIRE) -- Verde AgriTech Ltd (TSX: “NPK”) ("Verde” or the “Company”) is pleased to announce the carbon capture properties of its K Forte® and Super Greensand® (“Products”), as detailed by an independent study conducted at Newcastle University under the leadership of Prof. David Manning, PhD, a renowned soil scientist (the “Study”). The carbon dioxide (“CO2”) capture is inherent to the Products and is estimated at 120kg per tonne. The CO2 removal does not require any change to the Products’ production and farmland application methods, nor does it change the nutritional benefits to plants. As a result, in the production scenario of 50 million tonnes per year (“Mtpy”),1 Verde would be one of the world's largest carbon capture projects with a total of 6 million tonnes of CO2 permanently subtracted from the atmosphere every year.

The Science on Enhanced Rock Weathering and the Study Findings

Enhanced Rock Weathering (“ERW”) is a naturally occurring process whereby CO2 is removed from the atmosphere when it reacts with silicate minerals present within certain types of rocks. In other words, through weathering, certain types of minerals naturally absorb CO2 from the air and store it permanently as part of the new mineral structure.

Over many years, Verde's prospecting led to the identification of a silicate mineral that is rich in glauconite (the “Rock”). It is distinctive in its faster weathering rate compared to other minerals used in ERW schemes, such as basalt, which allows the Rock to capture CO2 more rapidly. In a parallel benefit, the Rock is a source of several plant nutrients including potassium (represented on the periodic table as “K”), which is a crucial element for plant growth, and is a proven substitute for Potassium Chloride (“KCl”). 

To evaluate Verde's Products, the Company engaged Professor David Manning Ph.D., who is a leading expert in ERW. Dr. Manning has been a member of the Institution of Geologists since 1979, was the president of the Geological Society of London from 2014-2016, member of Council of the European Federation of Geologists (“EFG”) and chaired the EFG's Panel of Experts on Soil Protection. He has extensive publications on the topic of soil and its role in combating climate change.2,3

Analyses performed on Verde's Products at Newcastle University have confirmed its efficiency to extract CO2 from the atmosphere at a ratio of 120kg of CO2 per 1 tonne of Product, based on a well-established scientific calculation formula.4 In conclusion, Verde’s Rock undergoes ERW to permanently capture atmospheric CO2 while releasing K and other plant nutrients.

Previously, following extensive geological research of the Rock, including over 40,000 meters of drilling and chemical analyses, Verde had commissioned an independent mineral resource and reserve study under the Canadian National Instrument 43-101, which has established a combined measured and indicated mineral resource of 1.47 billion tonnes at 9.28% K2O and an inferred mineral resource of 1.85 billion tonnes at 8.60% K2O (using a 7.5% K2O cut-off grade).5 This amounts to 295.70 million tonnes of potash equivalent in K2O. For context, in 2021 Brazil’s total consumption of potash in K2O was 6.57 million.6

Professor David Manning commented on the findings: “For over 40 years I have devoted the bulk of my research to how we can exploit soil processes to mitigate the effects of anthropogenic greenhouse gas emissions. More specifically, I use my research-based understanding of how soils and their constituent minerals interact with the biosphere in the context of carbon capture and plant nutrient supply. It was therefore no surprise when our research demonstrated the potential of Verde's Products to absorb CO2. More impressive is Verde's total mineral resources’ potential to remove around 398 million tonnes of CO2 from the atmosphere,7 in what will be a significant contribution to global efforts to reduce atmospheric CO2 levels.”

Verde’s ERW Carbon Capture Potential

Scalable and cost-effective ERW carbon capture projects depend on farmers' willingness to apply minerals on a large scale over their farmland. In that sense, Verde's has multiple advantages in ERW:

  1. The Products have fast dissolution rate, as evidenced by agronomic trials and potassium release.
  2. The Products are sources of essential macronutrients for plants, which creates significant motivation for farmers to adopt them in place of traditional chemical fertilizers;
  3. The Products have certified mineral reserves proving reliably consistency in their mineralogy, carbon capture effectiveness and absence of deleterious elements;
  4. The Products are certified organic by several governmental and non-governmental organizations, including some of the most stringent global standards such as the Washington State Fertilizer Registration and the California Department of Food & Agriculture;
  5. The Products undergo meticulous particle size control when of its manufacturing process, guaranteeing a consistent particle size distribution. This is advantageous because particle size is essential for optimal carbon capture and its calculation.

Few carbon capture projects based on ERW showcase all, if any, of the above advantages which are consistently delivered by Verde.

Cristiano Veloso, Verde’s Founder and CEO, commented: “This is a disruptive moment for agriculture in general and Verde in particular because it marks the point when plant nutrition can be directly and quantifiably linked to permanent carbon capture. As a company and team, at Verde we have always been committed to sustainable and environmentally friendly solutions for agriculture. We are now devoting significant energy and resources to the Life Cycle Analysis, which will determine our products' carbon footprint - if there is any and how best to pursue monetization from potential carbon credits. Verde is uniquely positioned to help feed the world and reduce greenhouse gases in our atmosphere.”

Next Step: Life Cycle Analysis and Carbon Credits Studies

Verde has commissioned a leading Canadian consultancy firm to conduct a comprehensive Life Cycle Analysis (LCA) of its Products. The LCA will provide a more complete understanding of the overall carbon footprint of Verde AgriTech's products, from mining through processing and delivery, thereby allowing for an exact calculation of CO2 captured. The fact that 100% of the electricity used by the Company comes from renewable zero emission hydropower will contribute to ensure a negative carbon footprint.

The Company will also determine how its Products can meet the requirements necessary to generate carbon credits. In 2022 the global market for carbon credits totalled US$ 909 billion.8

KCl Compared to Verde’s Product

Potassium chloride (KCl) is the conventional source of potassium, produced mostly in Canada, Russia, and Belarus. Brazil is highly dependent on imported KCl, accounting for over 96% of the total potassium used in the country's crops. Despite its effectiveness as a potassium fertilizer, the production and use of KCl have resulted in significant environmental and social costs. The manufacturing process of KCl, has been linked to devastating effects, including human fatalities, large-scale water pollution due to chloride contamination, and the formation of sinkholes leading to the destruction of an entire city.

Contrary to KCl, Verde's Product is economically more viable and sustainable because it does not contain chlorine, has gradual release, does not leach out with rain or irrigation water, and does not cause soil salinization. Verde’s Products have a much smaller carbon footprint compared to KCl because it does not need to be transported over transcontinental distances, being produced close to its finally point of application, rely on electricity produced from renewable sources, and once applied to soils it captures carbon.

In Q1 2023, 8,559 tonnes of chloride have been prevented from being applied into soils by farmers who used the Product in lieu of potassium chloride fertilizers.9,10 A total of 121,201 tonnes of chloride has been prevented from being applied into soils by Verde’s customers since the Company started production. Once it achieves the production capacity of 50 million tonnes per year, the Company aims to mitigate the application of approximately 94.5 billion tonnes of chloride into soils over time11 in collaboration with its customers.

Furthermore, Verde’s Products are produced close to its finally point of application, rely on electricity produced from renewable sources, and once applied to soils they capture carbon.

Finally, KCl is not approved for organic farming due to its harmful impacts on the environment. Its extensive use has been associated with damaging effects on soil health and microbiome balance, as well as contributing to chloride leaching into water systems. Whereas Verde's products are certified organic.

Verde plans to use carbon credits to reduce the price of the Product to farmers while increasing overall profitability, therefore further incentivizing the substitution of KCl.  

Select Historic Overview of Verde’s Environmental Initiatives

Verde has an extensive history of commitments towards sustainable and productive agriculture. Below are some of the highlights of recent years that help ensure that the carbon capture initiative of the Company is buttressed by best-in-class environmental practices.

In September 2019, the Company was awarded the “Good Environmental Practices Award,” promoted by the State System of Environment and Water Resources (SISEMA, in Portuguese) in the category “Best Practice of Mineral Solid Waste Management.” The Company has presented its sustainable mining project that is intended to improve the health of people and of the planet.

In June 2021, the Company launched N Keeper, a proprietary processing technology for the Rock that alters its physical-chemical properties to enable ammonia retention for use as a calibrated additive in Nitrogen fertilizers. N Keeper leads to the reduction of Nitrogen volatilization loss, which provides the efficiency of crop fertilization increase, mitigation of environmental impacts, and reduction of climate changes.12

In April 2022, Bio Revolution, Verde’s technology that enables the incorporation of microorganisms to mineral fertilizers, was launched by the Company. K Forte® is the first fertilizer in the world to use Bio Revolution technology. Bacillus aryabhattai, a bacterial strain widely renowned in agriculture for its multiple benefits, is the first microorganism to be incorporated into Verde's Product.13

In February 2022, the Company's Brazilian subsidiaries, Verde Fertilizantes LTDA and FVS Mineração LTDA, earned ISO 9001 and ISO 14001 certifications.

ISO 9001 is the international standard that specifies requirements for a Quality Management System, demonstrating good management practices throughout the Company’s processes. This certification reflects Verde’s commitment to meeting the highest standards of environmental protection and adopting a responsible approach to environmental issues in our operational activities.

ISO 14001 is an international standard that sets out the requirements for an environmental management system. It helps Verde to improve our environmental performance through more efficient use of resources and reduction of waste.

Through the implementation of the Environmental Management System in accordance with ISO 14000, Verde has established and maintains specific policies and procedures for identifying, monitoring, and controlling the environmental aspects of our operations, with the aim of minimizing negative impacts on the environment, preventing pollution, and promoting sustainability.

Moreover, we continue to actively seek opportunities to improve our environmental performance, through training and awareness programs developed for our employees, as well as the pursuit of technological innovations and more sustainable practices in our operations.

ISO 14001 certification shows Verde's commitment to protecting the environment and operating transparently and responsibly regarding environmental issues.

Furthermore, Verde's mining and processing do not require tailings dams. Its mined area is mainly composed of degraded pasturelands that, once mined, Verde transforms into tropical forest. To that end, the Company planted 4,300 trees in 2019, 5,000 in 2020, 9,888 in 2021 and 10,341 in 2022, totaling over 29,500 trees planted. All planted species are native to the region located around the Company's production area.

Over the past few years, the company has contributed resources to expand production. Since last year, with the start of operation of the second plant, Verde AgriTech has become the company with the largest potash production capacity in Brazil. At 3Mtpy production, which can be achieved at its existing production facilities with issued permits and licenses, Verde can capture 360,000 tonnes of CO2.

In June 2023, Verde’s shareholders voted overwhelmingly to approve the Company’s proposal to ban sales to Amazon Rainforest regions in a commitment to combat deforestation.14

9 Verde’s Product is a salinity and chloride-free replacement for KCl fertilizers. 1 tonne of Product (10% K2O) has 0.1 tonnes of K2O, which is equivalent to 0.17 tonnes of potassium chloride (60% K2O), containing 0.08 tonnes of chloride. Potassium chloride is composed of approximately 46% of chloride, which can have biocidal effects when excessively applied to soils.
According to Heide Hermary (Effects of some synthetic fertilizers on the soil ecosystem, 2007), applying 1 pound of potassium chloride to the soil is equivalent to applying 1 gallon of Clorox bleach, regarding killing soil microorganisms. Soil microorganisms play a crucial role in agriculture by capturing and storing carbon in the soil, making a significant contribution to the global fight against climate change.
