[China Environmental Protection Online Star Enterprise] Sludge treatment and disposal is a worldwide challenge. Currently, there are various treatment methods, but none can completely eliminate sludge without causing secondary pollution during the process. Hunan Dingjiu Energy & Environment Technology Co., Ltd.'s integrated sludge continuous carbonization technology has broken the industry's long-standing bottleneck, truly achieving harmless, reduced, stabilized, and resourceful sludge treatment.
Dingjiu Environment transforms into a sludge carbonization magician, helping "sludge" realize its blue dream
As a "by-product" of wastewater treatment, China's sludge production has been increasing year by year. According to relevant statistics, municipal sludge production reached 35 million tons in 2015. It is estimated that from 2016 to 2020, China will generate about 400 million tons of sludge, and the sludge treatment and disposal market will reach 189.2 billion yuan.
After the "Water Ten Measures" formally sounded the clarion call for sludge treatment, China's sludge treatment has entered a new era of rapid development. With further improvement of relevant policies and increasing industry concentration, companies such as Hunan Dingjiu Energy & Environment Technology Co., Ltd. (referred to as "Dingjiu Environment") have risen in response to the right time, place, and people, steadily advancing in the blue ocean market, and have become a force to be reckoned with in China's environmental protection industry.
At the 2016 China (Zhejiang) International Energy Conservation and Environmental Protection Industry Expo held at Ningbo International Convention and Exhibition Center from October 13 to 15, Ms. Wang Yajie, Deputy General Manager of Dingjiu Environment, accepted an exclusive interview with a reporter from China Environmental Protection Online, providing a detailed introduction to the company's development, industry status, and core technologies and products.

As an environmental enterprise specializing in sludge treatment and disposal technology R&D, related equipment manufacturing, and providing systematic technical services, Dingjiu Environment has successfully built a seasoned 'iron army' of R&D, production, and management with high overall quality and strong innovation spirit. Over decades, it has developed the Integrated Sludge Continuous Carbonization Technology and DJ Modular Combined System Equipment.
According to Ms. Wang Yajie, Dingjiu Environment holds complete independent intellectual property rights for the Integrated Sludge Continuous Carbonization Technology, filling a gap in the domestic sludge treatment and disposal industry. It has successfully applied for 20 national invention patents and related PCT international patents, attracting high attention from all parties.

Compared with sludge treatment technologies such as anaerobic digestion, incineration for power generation, and building material utilization, the Integrated Sludge Continuous Carbonization Technology has unique advantages and can be fully accepted by disposal terminals, effectively turning sludge into treasure. In the interview, Ms. Wang Yajie also stated that the Integrated Sludge Continuous Carbonization Technology and DJ Modular Combined System Equipment have seven major characteristics and advantages:
(1) Sludge undergoes drying and dry distillation carbonization in a sealed equipment, which is environmentally friendly and causes no pollution. (2) After carbonization, the physical and chemical characteristics of sludge completely disappear, replaced by pollution-free, usable carbon substances, thoroughly eliminating the existence of sludge. (3) During the sludge carbonization process, the heat generated by the sludge and biomass materials themselves is used for heating and evaporation, essentially consuming no external energy, saving a large amount of energy. Moreover, a large amount of thermal energy is output during the condensation process, thereby reducing total operating costs and also enabling recovery of thermal energy for benefits. (4) The biochar produced as a byproduct during sludge carbonization can be used as a soil remediation material, able to restore soil ecological functions (similar to the ecological functions of Northeast black soil) and reduce heavy metal content in crops (can reduce cadmium content in crops by 30-60%); it can also be used as a supplementary material for steel plants, replacing energy-intensive supplementary materials. (5) The DJ Modular Combined System Equipment integrates sludge drying and carbonization modules, is highly integrated and simplified, adopts PLC parameter control, and is simple to operate; (6) The DJ Modular Combined System Equipment can directly handle sludge with moisture content of 50-80%, showing strong adaptability; (7) Through permanent carbon sequestration and biomass energy utilization, negative carbon emissions are achieved, increasing carbon sinks significantly. At a scale of 100 tons/day, it can reduce carbon emissions by approximately 36,000 tons per year.

Some applications of integrated continuous sludge carbonization technology
"Dai Xiaohu, Dean of the College of Environmental Science and Engineering of Tongji University, stated that China's annual sludge output is currently 30-40 million tons, and the existing treatment level and technology in the sludge disposal industry are far from meeting current treatment needs. The integrated continuous sludge carbonization technology truly achieves harmless, volume-reducing, stabilizing, and resourceful sludge treatment. The recovered carbon has diverse uses, including heavy metal soil remediation and improvement, insulation materials for steel plants, and carbon-based fertilizers for landscaping and greening, truly realizing resource recycling." Ms. Wang Yajie said.
Products are the best carriers of technology. It is reported that Dingjiu Environment, based on the above technology, launched the integrated continuous sludge carbonization furnace, which received widespread recognition and praise from the industry as soon as it was introduced. The market is the only standard for testing products. Core technological innovation has made Dingjiu Environment stand at the forefront of the industry, with market share rising steadily and unlimited future development prospects.
Currently, China's economic development has entered a new era of the 13th Five-Year Plan. The energy conservation and environmental protection industry remains hot, and the sludge treatment field is still a blue ocean. The market has shown signs of explosive growth, and social capital is beginning to stir. On the eve of such a feast, industry transformation and restructuring are the general trend. The rise and fall of enterprises are common occurrences in business. Everything changes rapidly, and everything is unknown. But no matter what, technological innovation means the aggregation of core competitiveness. Based on this, Dingjiu Environment is bound to maintain an invincible position, growing stronger through continuous exploration and advancement, helping "sludge" realize its blue dream.
