Green development makes the future sustainable forever. A good ecological environment is the basic foundation for the sustainable development of people and society. Since the iron and steel industry was relocated and adjusted, Shougang has been exploring the direction and paths of the industrial transformation development. In recent years, following the green development philosophy, Shougang has been looking for opportunities surrounding city development, concerns of governments, people’s demands, ecological environments, etc., and has vigorously developed the environmental industry, formed its unique model, achieved good economic, environmental and social benefits, produced great demonstration effects and attracted extensive attention.

Adhere to the strategic guide and build the whole industry chain

The development ideas of “Innovation, Coordination, Green, Open and Sharing” proposed by General Secretary Xi Jinping at the Fifth Plenary Session of the 18th CPC Central Committee is the concentrated reflection of the development thought, direction and focus of China for the 13th Five-Year Plan period or even a longer period. The five major development concepts have a stronger guiding significance to Shougang.

When the CPC committee of Shougang Group planned the development of Shougang for the 13th Five-Year Plan period standing at the new historical starting point, it firmly adhered to and thoroughly implemented the Five Major Development Concepts and conscientiously integrated the new ideas into the processes of planning the development, implementing the tasks and deploying the work. Shougang has planned to build itself into a large comprehensive enterprise group with global influence. It vigorously develops the environmental industry as one of its important measures to implement its GREEN development concept, which is also part of its key argument of promoting the transformation development and building a comprehensive urban service provider.

Both the Beijing Municipality CPC Committee and the People’s Government of Beijing Municipality pay high attention to Shougang’s environmental industry development. Secretary Cai Qishu went to Shougang’s Lujiashan Circular Economy (Venous Industry) Base, did the field research, guided the work and gave important instructions when he worked in Beijing for less than a month. He indicated the direction of development  for the environmental industry of Shougang and vitalized this development.

Green development is becoming Shougang’s new pursuit and new driving force in developing transformation, solving urban solid waste problems, benefiting people’s livelihood and optimizing the environment, and it is also the endeavor and vitality of the sustainable development of Shougang. Urban solid waste recycling and reuse are specific reflections of the implementation of Shougang’s green development concept and intrinsic requirements of green and sustainable development. Centering on the formulation of the 13th Five-Year Plan of Shougang Environmental Industry Corporation Limited, leaders of Shougang Group such as Jin Wei and Zhang Gongyan have heard special reports and proposed definite requirements.

To further achieve the standardized management and rapid development of Shougang environmental industry, Shougang Environmental Industry Corporation Limited was established in January 2014. As a management platform to develop the energy-efficient and environment protection industry of Shougang, Shougang Environmental Industry Corporation Limited deeply practice the green development concept, formulated a five-year action plan and established eight key projects. Since the beginning of the 13th Five-Year Plan period, Shougang Environmental Industry Corporation Limited has firmly seized the strategic opportunity period of the environment industry development, established an industrial platform management architecture, streamlined the internal management, strengthened the corporate self-supporting construction, enhanced the support for the industrial development, cultivated an excellent construction, technology and operation team and turned human resources into the foundation for corporate development, according to the requirements of the CPC committee of the group: “Vigorously promote the urban environment protection industry, actively promote the construction of the national-level Lujiashan Circular Economy Demonstration Base, quickly replicate the industrial park mode, strengthen the contaminated soil remediation, etc., spare no efforts grabbing the market share and raising the brand image of Shougang Environment.” At present, Shougang Environmental Industry Corporation Limited have successively established and implemented multiple projects such as Shougang Biomass Energy, Construction Waste Recovery and Utilization and Contaminated Soil Remediation and planned and designed Beijing Lujiashan Circular Economy (Venous Industry) Base.

Shougang Lujiashan Circular Economy (Venous Industry) Base is China’s first urban solid waste treatment demonstration base approved by the National Development and Reform Commission. The base plan includes over 10 projects such as household garbage, kitchen waste, construction waste and sludge. In addition, a publicity and education center has been set up for the public. It includes five specific exhibition halls on waste treatment — the World Hall, the Ancient Chinese Hall, the Modern Chinese Hall, the Contemporary Chinese Hall and the Future Imagination Hall (future city imagination). The exhibition contents include the whole process exhibition before and after the harmless, reduced and recycle treatment of the urban solid waste such as household garbage, kitchen waste and civil sludge, and the scientific publicity of the circular economy feasibility and necessity. The center has successively received over 16,000 visitors by building the circular economy (venous industry) exhibition window and it has been awarded “the Training and Teaching Practice Base, the Publicity and Education Center, the Ministry of Environment Protection” by the Ministry of Environment Protection.

In recent years, Shougang has vigorously developed the urban environment protection industry, formed a characteristic Lujiashan environment industry development mode, provided a fully-circular, whole-process and all-functional customized solid waste solution for cities, achieved good economic, environmentally friendly and social benefits, produced excellent demonstration effects and attracted extensive high attention domestically and abroad.  

At present, Shougang Lujiashan Industrial Mode are being actively promoted and copied in domestic cities. The projects under construction and being implemented are as follows:

—— Shougang Biomass Energy Phase One Project is the world’s largest monomer waste incineration power generation project that has been put into operation in one go. Its annual waste treatment quantity is one million tons. Since it was put into operation, the whole operation status has been good. So far, it has accumulatively treated over 3.4 million tons of waste and generated over one billion kilowatt hours, which is equivalent to having saved a large landfill in Beijing.  

—— On June 19, 2017, Phase Two of the biomass energy project obtained permission from the Beijing Development and Reform Committee for the early-stage work to be carried out.

—— On March 30, 2017, Shougang Environmental Industry Corporation Limited and Shougang Changye (Group) Co., Ltd. joined hands and won the bidding of the harmless main urban household garbage treatment project in Changye city, Shanxi Province. At present, the project construction will start soon.

It has also obtained the laboratory approval certificate from China National Accreditation Service for Conformity Assessment.

The waste incineration power generation technology has reached the international advanced level ———

Independent innovation is the everlasting endogenous power of the enterprise. Shougang Biomass Energy Project is one of the key projects of Lujiashan Venous Industry Base and an important livelihood project of Beijing determined by the CPC committee of Beijing and the People’s Government of Beijing. It is also Shougang’s first environment protection and livelihood project after it implemented its strategic transformation and vigorously developed the environment protection industry in Beijing. Shougang Biomass Energy Project is the world’s largest monomer waste incineration power generation plant that has been put into operation in one go. Its treatment scale has reached 3,000 tons/day and its annual waste treatment capacity is one million tons. The project is the first domestic waste incineration power generation plant to adopt the advanced design ideas of “Green, environment protection and innovation,” use the most advanced flue gas treatment process and adopt the selective catalytic reduction (SCR) denitration. It has adopted an extraction and condensing steam turbine generator unit and realized cogeneration. It is the first to use air-cooling technology in the domestic waste incineration power generation, which can save 80% of the water involved, and adopted some energy-efficient and environment protection technology such as comprehensive rainwater utilization, marsh gas power generation and solar power generation. The project has become an environment education base in Beijing and one of the first batches of energy-efficient and environment protection education demonstration bases of China Resource Recycling Association. The overall technology of the project has reached the international advanced level. The project has played an important role as a benchmark and demonstration of the domestic waste treatment industry and it has very extensive promotion value.

A leader of Shougang Environment Industry Corporation Limited stated in a press interview that we were actively planning and preparing the construction of Phase Two of Shougang Biomass Energy Project and on June 19^th we were informed by Beijing Development and Reform Commission that the early-stage work of Phase Two of Shougang Biomass Energy Project could be carried out. The project is a comprehensive waste incineration project integrating household garbage, stale refuse, medical waste and sludge treatment. To extend the industrial chain, it will comprehensively treat cinder and flying ash. The implementation of the project will increase the waste treatment capacity by 3,000 tons/day, the waste treatment capacity of Phase One and Phase Two will be 6,000 tons/day and it will be one of the most prominent green household garbage incineration power generation projects in the world. The project will strengthen our determination and confidence to turn the Lujiashan base into China’s first national circular economy industry demonstration park integrating multiple solid waste treatments with a collaborative mechanism.

Become Beijing’s industrial contaminated land remediation engineering and technology research center ——

Scientific innovation is the foundation for corporate survival, competitive drive and enterprise development. The contaminated land remediation is a new important industry for Shougang to build its environment brand. To develop the contaminated land remediation industry, Shougang Environment Industry Corporation Limited has specially established the Shougang Thermal Desorption Soil Remediation Project. The technological process is: Pretreating the contaminated soil including crushing soil and screening soil, transporting the soil to a drying kiln and preheating it, transporting it to a rotary kiln and carry out the thermal desorption, desorbing all the organic contaminants, clean soil cooling and coming out of the kiln tail. A manager assistant of Shouhua Company, a subordinate company of Shougang Environment Industry Corporation Limited, said that they had successively completed 14 technical transformation projects such as a raw material prescreening system, a raw material cross-belt de-ironing system, finished a soil storage yard, and all the treated soil had reached the first-grade standard specified in the Recycled Soil Environment Assessment Guideline after Contaminated Soil Is Remedied.

In the development of the contaminated land remediation industry, on one hand, Shougang Environment Industry Corporation Limited carried out the contaminated land remediation project and accumulated performance, and on the other hand, it actively did the early-stage R&D and experiment work of contaminated soil technology such as the electromagnetic wave method, the bio-pile, the indirect thermal desorption and the post-remediation soil recycle and utilization to be technically prepared for the industrial development. The electromagnetic wave technology used to treat contaminated organic soil dominates the domestic industry. At present, Shougang Environment Industry Corporation Limited is cooperating with some relevant scientific and technological institutions in carrying out laboratory-scale and pilot-scale tests and it has achieved some active progress. In addition, it has actively applied for and has been successfully approved as Beijing Industrial Contaminated Land Remediation Engineering and Technology Research Center, which will lay a solid foundation for turning the contaminated land remediation industry into comprehensive services, integrating “technical R&D, consultation, engineering construction and operation management.”

Comprehensive construction waste utilization with Shougang characteristics and independent intellectual property rights ——

Scientific and technological innovation is not only the vital source of development and progress of the enterprise, but it is also a strong driving force that helps the enterprise achieve secondary breakthroughs. Construction waste has been considered as the most promising and inexhaustible “urban mineral resources” by many countries. In the construction waste treatment aspect, Shougang has developed a green comprehensive utilization road with Shougang characteristics and independent intellectual property rights that turns construction waste into construction materials. It has accumulatively treated over 60 tons of construction waste and developed and produced recycled aggregates of over ten sizes and six series of recycled products, covering many construction materials such as building concrete, roadbed, blockwork, dry premixed mortar, pervious concrete, river waterbody treatment materials and landscaping materials. The recycled materials have been used in over 100 projects in many different fields of Beijing such as urban appearance, roads and construction.

To promote the application of the recycled aggregates from construction waste, Shougang Environment Industry Corporation Limited has conducted construction waste recycled concrete technology research successively together with Beijing University of Civil Engineering and Architecture, Beijing University of Technology, Beijing Building Material Scientific Research Institute, etc., carried out the product application tests cooperating with some concrete companies such as Beijing Building Materials Group Co., Ltd., Jidong Development Group Co., Ltd., Beijing Urban Construction Group Co., Ltd., etc., carried out the pilot-scale test verification on roads around Shougang Resources Co., Ltd. and at the parking lot of Beijing Building Material Scientific Research Institute and achieved good results. The products have been examined, evaluated and approved by the Recommended Green Construction and Energy-Saving Product Expert Committee of China Association for Engineering Construction Standardization, they have been awarded the Recommended Green Construction and Energy-Saving Product Certificates and they have been recommended to the project construction field for use.

Integrate the mature and advanced domestic kitchen waste treatment technologies ——

Surpass giants by standing on their shoulders. Shougang’s waste collection and transportation project of 100 tons of kitchen waste per day is one of the key projects of Shougang’s Lujiashan Circular Economy (Venous Industry) Base. It is one of the key livelihood projects of Beijing. The area of the project’s construction land is 10,917.41 square meters. The treatment scope includes all the kitchen waste of Mentouguo and Shijingshan, covering the whole city. The technological process mainly depends on the pretreatment system, the anaerobic system, the biochemical system, the water treatment system and the deodorization system to complete the recycling of grease, marsh gas and biological humic acid, and the comprehensive treatment of wastewater and odor vapors. After solid and liquid kitchen waste is separated, the wastewater can be treated so that it can reach the standard and be discharged. The waste oil and fat can be processed into biodiesel, the residues can be made into marsh gas through anaerobic fermentation and the gas can be used to generate electric power. Kitchen waste is treated by making it harmless, reducing its size and recycling it. It has been predicted that the project will be put into operation in the first half of 2018.

According to the introduction by Mr. Wang Dong, a researcher of the Technical Design Center of Shougang Environment Industry Cooperation Limited, The Beijing Shougang Daily 100 Tons of Kitchen Waste Collection, the Transportation and Treatment Integration Project started to be researched in 2014 and a design institute was entrusted with formulating a technological process solution. To ensure the feasibility of the solution, the Design and Technology Center of Shougang Environment Industry Corporation Limited specially established a kitchen waste project group in 2015 to carry out research. The research group consisting of four technicians, including Mr. Wang Dong, conducted extensive survey and investigation activities while digesting the early-stage design solutions. The group conducted multiple rounds of technical exchange and discussion with 17 famous domestic kitchen waste treatment enterprises and visited 15 domestic kitchen waste treatment plants in Chongqing, Chengdu, Hangzhou, Changzhou, Linyi, Liaocheng, etc. After the group carried out these exchanges and visits, it prepared 16 investigation reports and gathered a systematically understanding of domestic kitchen waste collection, transportation and treatment, and the relevant equipment application and development status. It also found existing defects and problems of the original design plans in the actual application and process configuration. Mr. Wang Dong and the other scientists have put forward their technological process optimization and improvement proposals after they repeatedly proved their ideas. They finally integrated the mature and advanced domestic kitchen waste treatment technology and formed their technical plans that are suitable for the characteristics of kitchen waste treatment of Beijing, which reduces the investment risk significantly.

 Take over duties as a responsible enterprise.

“If you draw strength from a group, you will prevail. If you draw wisdom from a group, you will achieve great things.” While Shougang Environmental Industry Corporation Limited is on its way to becoming an urban solid waste environmental protection industrial company, the employees stand at their posts, sparing no efforts in overcoming difficulties, continually creating miracles and delivering satisfying answers.

“It’s our duty, mission and responsibility to develop the new contaminated land remediation industry and carry out the Shougang Thermal Desorption Soil Remediation Project.” General manager Zhao Shengli of Shouhua Company, Shougang Environmental Industry Corporation Limited shared his experience. The Thermal Desorption Soil Remediation Project has been a path of hardship and difficulty for them. Soil thermal treatment requires fuel, meaning that industrial natural gas must be imported, but the procedure for industrial gas import can be very strict. When pipelines are being laid, many complicated conditions must be taken into consideration, such as a safe distance from bleed air, surface building obstacles and demolition. Zhao Shengli said, “Importing gas is no cakewalk.” At that time, Shouhua Company only had six employees. As the head, Zhao Shengli managed 2-3 employees and dealt with relevant assessing officers of the natural gas company and more than 10 of its departments and units. He also led the natural gas company staff in conducting route survey and helped with a series of difficult tasks, including surface building demolition. The repeated modification and adjustment of the natural gas pipeline import plan brought great difficulty to the route survey. Unit owners of certain sections couldn’t be reached, some other owners refused to cooperate or understand. It’s very common for the on-site investigators to have their clothes tattered or to be left out in the cold. Each step of the process, including brainstorming, conceiving, designing, planning, operating, investigating and implementing, is completed with endless bitterness and sweetness, difficulties and challenges... By working hard, inheriting the spirits of “daring to do, daring to persist, daring to work hard,” carrying forward the spirits of “daring to take responsibility, daring to innovate, daring to lead,” they eventually succeeded in importing the 1.4 km long industrial natural gas pipeline, and ensured the smooth construction and commission of the Thermal Desorption Soil Remediation Project.

When Shouhua Company was restoring the contaminated site of Shougang’s old Beijing plant, Shouhua Company conformed to Shougang’s requirement of “Shougang independently treats its contaminated soil,” and actively carried out the restoration of the contaminated site of the old Beijing plant. Associate general manager Wan Zhen of Shouhua Company explained that they overcame hardships in the new business, worked hard for three years to cultivate talents and accumulate technical experience, achieved the development of the newly-born contaminated site restoration industry from nothing, and turned many impossible things into the possible. Today, the number of employees has grown from more than a dozen to over 100. In the meantime, Shouhua Company has acquired the qualification of “Beijing technological research center for soil remediation in contaminated industrial sites.” Since 2014, Shouhua Company has organized and completed the dredging, transportation, storage and some other tasks concerning the contaminated soil of Eastern Liangshuichi Road, Tegang sections No. 15 and No.16, along with other projects. Over 100,000 cubic meters of contaminated soil have been dredged and transported to ensure the timely implementation of the Scheduled Eastern Liangshuichi Road Traffic Opening Project and Shoute Green Energy Port Project.

Meanwhile, Shougang Environmental Industry Corporation Limited adhered to the outward development strategy, embraced the golden development era of contaminated site restoration, and urged Shouohua to actively undertake the contaminated site restoration project of Guiyang Special Steel Co., Ltd. This project is a key project for Shougang Environmental Industry Corporation Limited to develop non-local markets, expand and recreate projects, as well as an environmental protection project that highly involves Guiyang municipal government and even Guizhou provincial government, enthusiastically supported by Guiyang Special Steel Co., Ltd, Shougang Real Estate Development Co., Ltd and the local government departments. The project contains a total amount of about 380,000 cubic meters of contaminated soil, which will be restored in four phases in coordination with the development plan of Guiyang Shougang Real Estate Development Co., Ltd. The project’s restoration plan was put on records at Guiyang Ecological Civilization Construction Committee on November 25,2016, and the project officially commenced on January 6, 2017. Up to now, over 40,000 cubic meters of contaminated soil have been dredged and transported. In the meantime, the construction of the storage site and pre-treatment facility for contaminated soil have been carried out. The No.1 gas film shed has been inflated.

To ensure the progress of the project, Shouhua Company quickly formed the Guiyang Special Steel Project Department. The cadre and staff “rolled up their sleeves and worked hard,” overcame difficulties including complicated field conditions, staff shortage and bad weather, and achieved phased breakthroughs in different aspects. The old plant of Guiyang Special Steel Co., Ltd has different sizes and types of contaminated areas. When they are overlaid with each spatially, they can generate great difficulty for the dredging work. During the dredging phase, the employees must verify the number of vehicles and weight in tons, create receipt copying tool, and supervise the on-site dredging work constantly in case bulks of concrete or ironware are mixed in. In the beginning, the unreliable and temporary structures and electricity on-site resulted in the employees of the Project Department organizing nighttime truck-loading, guiding the transportation in pairs using flashlights despite the rain. To make sure that the project progressed, the nighttime operators on duty began working at 11 pm, resting only after 2 am when all vehicles had left the plant and the site had been cleared up, not long before the start of another day’s work. The haul distance between the old plant of Guiyang Special Steel Co., Ltd and Guiding Hailuo Cement Plant is 75 kilometers. It has been a transportation route with very complicated conditions, specifically the bumpy mountain road to the cement plant. Guiding Count is a rugged land where rain falls too often. The daily rain, the winding road, the moist fog, they all bring difficulties to the transportation. Many local drivers refuse to transport soil. What makes it more difficult to construct a soil treatment facility in the worked-out mine area, is the lack of water and electricity. What should they do? According to Zhao Shengli’s explanation, they must climb the steep wall-like cliff, dig into the hard rocks, and carry sand and cement to the mountain to install high-voltage telegraph poles. On normal flat ground, it would take about one and a half year to build a soil storage and treatment gas film shed with a capacity of 70,000 cubic meters. Under such unfavorable natural conditions, they overcame difficulties and built a gas film shed with a floor area of 8,520 square meters and a capacity of approximately 70,000 cubic meters in three months. The gas film shed used for soil storage and pre-treatment satisfies the need of pushing forward the development of the Guiyang Special Steel Co., Ltd restoration land.

The contaminated site restoration project of Guiyang Special Steel Co., Ltd is the first project for Shougang Environmental Industry Corporation Limited to develop non-local markets, and expand and recreate projects. Its implementation laid a solid foundation for Shougang Environmental Industry Corporation Limited to achieve leap-over development at a high level. Playing the role of pioneer, it will be a golden business card for the industrial development of Shougang Environmental Industry Corporation Limited.

Everyone can innovate. Every day can be innovative. Every place can be innovated. Recycling construction waste is the best way to reduce construction waste, bringing huge economic and environmental benefits. Shougang Environmental Industry Corporation Limited follows the footsteps of Shougang’s transformation and development, took the lead in completing the construction of Shougang Construction Waste Recycling Disposition Project in Beijing with a set of independently-developed processes and technology. Designed to treat 1,000,000 tons of construction waste per year, the project has been officially put into production in 2015.

This year, Shougang Fushan Resources Group Limited strengthened its technological R&D and market promotion, and built the momentum for production and marketing. Employee Wang Jianming has made remarkable achievements in market exploitation. His efforts facilitated the formation of long-term strategic partnership between Shougang Fushan Resources Group Limited and Ningping Mortar Plant, and opened up a stable long-term marketing channel for 0-5 mm recycled aggregate. Meanwhile, Shougang Fushan Resources Group Limited developed the recycled mortar series with Ningping Mortar Plant, extended the product chain, increased the volume of business and further enhanced the brand image. The Technological Development Department of Shougang Fushan Resources Group Limited carried out research on the applied formula optimization technique for construction waste, explored different patterns of impact that construction waste had on mixture intensity, gradually changed most of the 0-5 mm aggregates into 0-10 mm aggregates, reduced the amount of lime and fly ash by 0.5%-1% or 3%. The production cost of the inorganic mixture is thus brought down by almost 5 RMB per ton. This year, from January to June, Shougang Fushan Resources Group Limited treated over 200,000 tons of construction waste, exceeding its expectation and reaching the peak.

Currently, Shougang’s recycled construction waste products have been successfully applied to over 100 project constructions:

--Taking part in a load-bearing structure project for the first time. It supplied about 3,000 tons of recycled coarse aggregate to be poured on concrete floors for the construction of Innovative Science and Research Demonstration Center, China Architecture Design & Research Group.

--Establishing a project with Beijing Municipal Commission of Transport, supplying the materials for municipal road construction. When Shougang Fushan Resources Group Limited was establishing a research project with Beijing Municipal Commission of Transport, it undertook the task of supplying the inorganic mixture for the construction of Guba Road, Fangshan District. A 1,000 meter road to be paved required 7,000 tons of material in total. The recycled construction waste aggregate is mainly used to lay the mid-level and ground level foundation of the road underneath the asphalt surface.

--Successfully applying recycled products to the construction of the Westward Road on Chang’an Street. 18,000 tons of inorganic mixture of Shougang Fushan Resources Group Limited was supplied for a major infrastructure project in Beijing; the second section of the Westward Road on Chang’an Street.

--Successfully applying the permeable concrete pavement recycled aggregate to the construction of Eastern Liangshuichi Road supporting the Winter Olympic Square. Eastern Liangshuichi Road is a main road reconstructed by the northern area of Shougang park, and a main road to the surrounding areas of the Winter Olympic Square. The permeable concrete pavement recycled aggregate can be used to effectively control rainfall runoff, and realize natural stockpile, permeation and purification to ease the pressure on municipal drainage system and relieve urban waterlogging.

--Application of green potted plants to the office areas of the Winter Olympic Games. This March, it cooperated with the marketing department of Shougang Greening Co., Ltd. and developed potted plant products suitable for office areas and families. Currently, there are 2,000 potted plants scattered in the office areas of the Organizing Committee for the Olympic Winter Games, further increasing the product width of Shougang Fushan Resources Group Limited.

“The force of wind tests the strength of grass. The coldness of winter selects the plant that lasts the longest.” The integrated deodorization system of kitchen waste collection, transportation and treatment is an important sub-project of the Integrated Project of Shougang 100 Ton/Day Kitchen Waste Collection, Transportation and Treatment. In 2016, postgraduate Wu Shuang of Peking University who newly entered the service undertook the task of designing the deodorization system. In order to carry out surveys and acquire valuable primary data on-site, Wu Shuang ran around for half a year, reaching a mileage of over 26,000 kilometers, the equivalent of the Long March road. Wu Shuang visited more than 10 waste treatment plants, stayed in the plants for more than 60 days for the survey, broke through mental barriers and endured the unpleasant smell of kitchen waste for a long time. Under such difficult conditions, Wu Shuang learned valuable information from people around him and came up with an improved technical plan more suitable for the Shougang Kitchen Project. The plan can ensure effective deodorization and save space occupied by the system. Eventually, the plan was applied to the design of the kitchen project, made corresponding optimization and improvement according to the causes of poor deodorization effect of the kitchen waste treatment plants and guaranteed streamlined implementation of the project’s follow-up work.

Other urban solid waste treatment projects of Shougang have also been carried out. Gradually, Shougang Environmental Industry Corporation Limited created a wealth of solutions to the disposal of urban solid waste and presented them at “The Fourth Chinese (Beijing) International Waste Incineration and Power Generation Industrial Fair 2017”, attracting a lot of attention. According to incomplete statistics, over 500 government departments and units visited the booth of Shougang Environmental Industry Corporation Limited for communication, consultation and negotiation.

Living in the present while looking into the future, Shougang Environmental Industry Corporation Limited strives to build the “Lujiashan base” model project, promote and replicate the Lujiashan industrial model to other domestic cities, and become one of the top national comprehensive urban environment service providers with worldwide influence. Shougang Environmental Industry Corporation Limited will do its best to accomplish the goal of treating 10,000 tons of domestic waste/day, 4,000,000 tons of construction waste/year, 500,000 tons of restored soil/year, 500 tons of kitchen waste/day and 1,000 tons of sludge/day by the end of the “13th Five-Year Plan” period.
