The company's registered address is Xigang District, Dalian City, Liaoning Province, and its registered capital is 10 million yuan RMB. Qingwu is a professional company with a focus on sludge dewatering and disposal. We specialize in the development of environmental protection technology, the provision of environmental protection technology services, engineering consulting and development services, and also the research and development, production, sales and installation of urban sludge drying and dewatering equipment. We are an innovative enterprise with a commitment to the research, development and application of comprehensive technology for the harmless, stabilizing, reusing, minimizing and eliminating of urban sludge. Qingwu's environmental protection services include the disposal of municipal sludge, industrial sludge, domestic waste and industrial solid waste. The company employs numerous highly skilled professionals with expertise. Our research and technological achievements in sludge disposal are unparalleled. We have developed innovative technology and equipment that enables us to reduce the water content of municipal sludge from 80-85% to less than 60%. After the comprehensive utilization, the water content can reach 45%. Furthermore, we do not add lime but only use green additives, ensuring that the further use of waste into treasure through sludge dewatering results in a low-cost, energy-efficient process.

Qingwu has extensive experience in project operation and management, which allows the Client to initiate the sludge disposal project at an early stage with minimal investment and to swiftly and effectively see the performance and benefits. Our company has a significant advantage in terms of power plant incineration demands and land resources, which provides a solid foundation for the success of the project in the final destination stage. Qingwu's self-developed technology, "ultra-high-pressure, high-efficiency physical dewatering + direct fuel-blending incineration in power plants," has the potential to address the issue of short-term emergency disposal within 3 to 5 years. This technology, together with the solution of "ultra-high-pressure, high-efficiency physical dewatering + aerobic fermentation composting", can be utilized for the ecological regreening of abandoned mines and the construction of eco-industrial parks. This will effectively address the challenge of low-cost and sustainable sludge disposal within a 5-year timeframe. This combined solution can enable the closed-loop treatment of municipal sludge, and achieve the goal of stabilizing, harmless, resourceful and zero-discharging of municipal sludge.
