How The Product Resolves Environment Problems

Biochar has a significant contribution to solving environmental issues. First of all, biochar is applied to the soil, where it helps to retain moisture and fertilizer. Although it does not contain the function of fertility, its porous structure can absorb and store water and fertilizers, thereby enhancing soil productivity. At the same time, for the soil contaminated by heavy metals, biochar can effectively absorb different harmful substances, preventing them from being absorbed by plants and further entering human food, thus reducing the threat to health. 

Furthermore, biochar is also used to handle fishery waste. For example, the carbon dioxide produced by high-temperature burning of oyster shells can activate biochar, which enhances its adsorption capacity and makes it suitable for industrial use. In addition, the calcium oxide produced after burning oyster shells becomes calcium hydroxide after adding water, which can be used to repair historical sites and manufacture environmentally friendly aromatherapy stones and other products, thus forming an efficient use of resources. These technologies not only increase the value of waste but also support the reduction of the negative impact of waste on the environment, creating an innovative circular economy model. 

Impact of The Produ​​ct & SDGs Goals

SDGs 9_ Industry, Innovation, and Infrastructure
  • Guantai Black Gold’s innovative practice in the circular economy had a clear connection to SDGS goal 9. They focus on making biochar the main material and use high-temperature activation technology to turn waste into high-quality products, like soil conditioners that can absorb heat materials for construction. This innovation added value to traditional industries and set a new standard for waste. They are also finding more ways to add biochar into other industries, and expanding their impact on sustainable materials. 
SDGs 11_Sustainable cities and communities:
  • Guantain Black Gold focuses on creating a more sustainable urban environment by recycling and reusing resources. They provide waste values and many uses by turning fish and agricultural refuse, such as oyster shells, into environmentally friendly items like scent diffuser stones. This enhances waste management and lessens urban trash. For instance, they use the calcium hydroxide produced by the burning oyster shell in the restoration of moments, which combined with the concept of circular economy, effectively extends the life of building materials and supports the preservation of the city’s cultural assets. Which not only improves the environment of the community but also contributes to the construction of a sustainable urban city.
SDGs 13_Climate Action:
  • Guantain Black Gold has played a significant role in addressing climate change. Their biochar products have improved the soil's fertility and water retention while they reduce carbon emissions in agricultural processes. Therefore, during the production of biochar,r they use high-temperature technology to decrease the greenhouse gases released during waste decomposition. By storing carbon, they also achieve carbon neutrality. These actions highlight the company's commitment to addressing climate change and making contributions to reduce the global carbon footprint.
