Environmental Protection
The positive impact of the circular economy on environmental protection lies in reducing emissions, minimizing the use of natural resources, and decreasing waste generation (What Is Circular Economy and Why Is It Important? | Repsol, 2023). This model contributes to maintaining human health and biodiversity by more efficiently utilizing natural resources such as water and land, and mitigating the effects of climate change (McGinty, 2021).
Currently, there is a significant issue of water waste in the operation of water trucks in the market. According to media investigations, some areas lack awareness of water conservation, leading to excessive water use and severe waste, especially in certain water-deficient cities, where annual consumption of tap water for road cleaning alone can reach 10 million tons. Globally, a regular fuel-powered water truck (with a water storage capacity of 12m³ per truck) consumes 72m³ of water per day, calculated based on six boxes of water needed for each truck's daily operation. With approximately 500,000 water trucks worldwide, the global daily water consumption on water trucks reaches 36 million tons (equivalent to 360 billion liters of water). If calculated based on the standard of 2 liters of water consumption per person per day, with a global population of approximately 8.02 billion, this means that the water consumed on water trucks every day is equivalent to the water consumption for 2.24 days for each person globally.

Global water resource utilization data shows that agriculture is the largest water consumer, accounting for 72% of total water withdrawal, followed by urban households and services at 16%, and industry at 12% (UN-Water, 2021). An area is defined as "water-scarce" when it recovers 25% or more of its renewable freshwater resources. Currently, 2.3 billion people globally live in water-scarce countries, with 733 million people residing in severely or extremely water-scarce countries (UN-Water, 2021). Additionally, approximately 1.42 billion people globally, including 450 million children, live in areas highly vulnerable or extremely vulnerable to water scarcity (UNICEF, 2021). In terms of agriculture, 3.2 billion people live in areas with severe or extremely severe water scarcity or scarcity, with 1.2 billion people, approximately one-sixth of the world's population, living in areas of severe water scarcity for agriculture (FAO, 2020). Furthermore, around 4 billion people, nearly two-thirds of the global population, experience severe water scarcity for at least one month in a year (Mekonnen and Hoekstra, 2016). These data highlight the severity of global water scarcity. To enhance resilience to climate change and provide services for the growing population, comprehensive and inclusive approaches must be adopted by society to manage this limited resource.
As a company committed to the circular economy, Jinkai deeply understands the current issue of water waste in water trucks and the challenges of global water scarcity. Therefore, Jinkai actively invests in the development of intelligent identification water trucks. The intelligent identification water truck adopts advanced intelligent visual identification systems, which, through visual identification technology and big data analysis, can accurately identify traffic signals. At the same time, combined with visual and humidity sensors, it intelligently determines road width and weather conditions of the day. During parking and waiting for traffic light conversion, the intelligent identification water truck automatically stops spraying water to save water resources. Additionally, it adjusts the spraying distance based on road width and turns off the water spraying function on rainy days or when humidity is too high to ensure efficient use of water resources. The intelligent identification water truck also intelligently controls water pressure based on road cleanliness to minimize water consumption. The application of these intelligent technologies endows the water truck with the function of intelligent water saving, giving it a "brain" to more intelligently and efficiently utilize water resources.

According to statistical data, the water consumption of Jinkai's intelligent identification water truck is approximately 57.6 m³. Compared to ordinary water trucks currently on the market, Jinkai's intelligent identification water truck can save up to 20% of water resources while maintaining the same level of cleanliness. Considering that there are approximately 500,000 water trucks globally, if each water truck is equipped with Jinkai's intelligent washing control system, the global daily water consumption on water trucks would be reduced to 28.8 million tons. Compared to the current 36 million tons of water, this means saving 7.2 million tons of water, equivalent to approximately 0.22 days of water consumption per person globally.
Therefore, Jinkai's intelligent identification water truck not only helps reduce the operating costs of water spraying operations but also plays a positive role in reducing water waste, demonstrating its commitment to energy conservation, emission reduction, and promoting the circular economy. This achievement highlights not only Jinkai's strength in technological innovation but also its outstanding contribution to sustainable development, making proactive efforts to build a green and environmentally friendly future.
