Central Leather And Environmental Report As A Green Escort

China Leather Association and China Environment newspaper went to the leather capital of China - Haining, Zhejiang, launched the "two learning and one" environmental protection special investigation.

This research is aimed at implementing the requirements of "two learning and one learning" in the Central Committee and the SASAC, and in line with the requirements of the Ministry of environmental protection in the late June to carry out the seminar on the innovation of grassroots research achievements and the special study and discussion of "two studies and one work", so as to promote the improvement of the environmental quality and implement the outstanding problems faced in the key tasks.

The Environmental Protection Bureau, Haining Ding Qiao sewage treatment plant, Haining leather leather Co., Ltd., Zhejiang general Leather Co., Ltd., Haining City Fu Sheng Leather Co., Ltd., Haining ZEHNDER Leather Co., Ltd., Zhejiang Limited by Share Ltd, Zhejiang Snow Leopard Dress Co., Ltd., and Zhejiang upper Fashion Co., Ltd., carried out grass-roots environmental protection research, and focused on the experience and lessons of the leather industry in the process of environmental protection, energy saving, emission reduction and green manufacturing. The results of environmental governance in recent years were summarized, and the advanced environmental protection technologies and innovative models adopted. The practical difficulties, problems and policy recommendations reflected by local governments, industry associations and enterprises were heard, and a feasible solution was discussed. Chen Zhanguang, Deputy Secretary General of the China Leather Association, Liang Wei, deputy director of the information department and Xu Weixing, China Environmental News reporter, accompanied by Gong Huihong, Deputy Secretary General of Haining Leather Industry Association, visited Haining city respectively.

Haining is the famous "leather capital of China". It is no doubt that with the development of Haining Leather City in recent years and its nationwide development, the brand name of Haining leather has also been polished and known to Chinese consumers.

What the outside world likes to say is that Haining's animal husbandry is located in the Hangzhou Jiaxing Lake Plain, but it has become one of the most important leather production bases and distribution centers in China.

In fact, Haining is not only the leader in the total economic output of leather industry in Haining, leather clothing output, fur trading volume, leather clothing and related products export, but also in the leading level in environmental protection. Especially in recent years, the environmental protection level of Haining leather industry has achieved a qualitative leap through the development of environmental protection verification in 2010, the "five water co governance" carried out in Zhejiang in 2013 and the rectification and upgrading of heavy polluting and high energy consuming industries deployed by the Haining Environmental Protection Bureau.

Haining leather industry has been upgraded through regulation. In 2013, compared with 2010, the amount of wastewater discharge and COD and ammonia nitrogen emissions decreased by 38%, 43.6% and 48.35% respectively. Compared with 2010, the total chromium emissions decreased by 37.7%, the annual chromium consumption decreased by 29.4%, the chemical material 22.12% decreased, and two years reduced by more than 2939 million yuan.

The hot issues of environmental pollution in tanning industry were basically solved. The problem of ammonia nitrogen exceeding the standard of tannery enterprises has been solved for a long time. The total chromium in the regulating tank has basically reached the standard, and the total discharge of pollutants can be kept stable and meet the standard discharge, thus achieving a win-win situation of economic and environmental benefits.

First, the government strictly enforce the law, the policy guidance and strict control are in sync; the association actively promotes the integration of resources to achieve scientific and technological tackling; enterprises are in place, and strive for innovation first.

From the government level, some local governments are affected by the local government.

In contrast, the environmental protection laws of the Zhejiang provincial government and the Haining municipal government are very strict. They not only allow the camera to leak, but also let the environmental protection become the sword of Damour, who is high above all enterprises.

From the association level, the leather industry association of Haining has played a very important role in promoting the leather tanning improvement in Haining. It helps enterprises change their concepts, publicize policies, make suggestions on the formulation of national and industrial standards, invite research experts to help enterprises to consult, integrate resources, and achieve scientific and technological research.

It is a great service to the home. It really wants to think about the business and the urgency of the business.

From the enterprise level, enterprises attach great importance to, devote all efforts to investment, technological innovation is the first priority, energy conservation and emission reduction start from details. In recent years, Haining tannery enterprises have invested more than million in environmental protection every year, some even more than ten million.

The use of slurry and chromium mud (about 15%-20% of chromium content) accounts for the cost savings (saving 100 tons of chromium per year). The public leather industry has also worked with solar energy technology companies to install solar panels at the top of the factory, converting solar energy into electricity, which has reduced electricity consumption and reduced energy consumption. Zhejiang snow leopard Garments Co., Ltd. has independently developed ERP system according to its own needs and characteristics, and has realized the management and tracking of the whole supply chain, laying a solid foundation for lean management. Snow Leopard Dress also tried to make leather products with chrome free tanning fabrics. These products are welcomed by consumers, making the company still maintain stable production and operation in the current depressed market environment. The use of new technologies to achieve energy conservation and emission reduction has become a common understanding. For example, Zhejiang Volkswagen Leather Co., Ltd. developed chromium recovery technology for chromium containing wastewater.

On the support of science and technology, Sichuan University, Shaanxi University of Science and Technology, Wenzhou University, Jiaxing University and other institutions have established a close relationship with Haining. With the authorization of academician Shi Bi, academicians of the Haining Leather Research Institute, rising leather and Wenzhou Red Dragonfly have set up provincial leather academician workstations.

At the same time, the Haining Leather Research Institute was set up in Haining, and a public laboratory of Zhejiang science and technology innovation service platform in leather industry was established, which played a major role in leather technology research.

Professor Lan Yunjun, Professor of Sichuan University, Professor of the Leather Research Institute of Wenzhou University, and other research experts often take a tour of the company, aiming at the practical difficulties encountered by enterprises, and jointly carry out scientific research.

Since 2010, reclaimed water technology, chrome free tanning technology, hair removal technology, hazardous waste treatment technology, photocatalytic deodorization and comprehensive utilization of chromium sludge have been put into use in scientific research institutions.

The three is that the person in charge of the enterprise should personally take the environmental protection as the "leader" project.

In the process of visiting Haining, our greatest experience is that business owners are environmental experts. They speak of environmental standards, technologies and indicators. What's more, the boss personally does technological innovation and environmental protection pformation. This kind of drilling and hard work is admirable.

"The first thing I do now is to use my cell phone to see the results of environmental protection tests.

Qian Zhiming, general manager of Haining brothers leather Co., said, on the one hand, he showed reporters online environmental testing data displayed on his cell phone.

In the workshop of Fu Sheng Leather Co., Ltd. in Haining, a reporter's attention has been paid to the spray type spray equipment above the leather conveyor belt. This is a new technology developed by Zhou Yonggen himself. This small technology not only saves water but also saves electricity. Small pformation in factories like this has become commonplace.

Zhang Mingfa, vice president and executive director of Zhejiang Carson Industrial Group Co., Ltd. showed us the latest roll coating equipment and low pressure airless spraying equipment, especially the latter, which was customized and reformed by Italy machinery and equipment factory according to their needs, which greatly reduced the waste of chemical material.

In order to better communicate with equipment dealers and traders, Zhang Mingfa even taught himself Italian, and now his Italian Italian has thumbs up.

Four, environmental protection is open and pparent, and the atmosphere of technology sharing is strong.

In the process of our research with China Environmental newspaper, all entrepreneurs are open and honest. They take us to visit, film tanning, fur, clothing production and sewage treatment, waste gas and sludge treatment.

"We know that the traditional tanning enterprises are very closed. They generally do not allow others to visit factories. I told enterprises that environmental protection is not related to the confidentiality of technology, they are common, and this taboo must be broken."

Gong Huihong, Executive Deputy Secretary General of the Haining Leather Industry Association, said that in order to promote each other in the work and carry out tannery environmental protection verification at the Ministry of environmental protection, the association requested that 9 enterprises at that time must have two environmental protection leaders in each household, and work together with the experts from the ring academy and Environmental Protection Bureau invited by the association to conduct house inspection.

Now leather entrepreneurs in Haining have developed a very open mind. Every year, they welcome companies from all over the country to visit and study. They are often invited to the field as an expert to introduce experience and promote technology.

They said frankly: "I wish everyone could use the same environmental protection technology as ours. The same advanced equipment, the better we learn, the better the governance is, the better the cost of pollution control is, and the competition is fair."

There is also a strong atmosphere for enterprises to share experiences in environmental protection and mutual help. It is often a successful technological breakthrough that extends from point to point.

For example, water-saving technology research, led by Fu Sheng fur Limited company, chose Spanish technology grafting, and made technical pformation to drum. This project invested about 2000000 of science and technology funds in Zhejiang province. The Haining Leather Research Institute and Fu Sheng fur and leather Co., Ltd. invested more than 600-700 million, and saved 30% of water consumption. In recent years, the technology has been further optimized, and the effect of promoting other enterprises in Haining has been very good. The sewage discharge has been reduced by 40%.

Five, environmental protection is based on cleaner production, with equal emphasis on equipment upgrading and meticulous management.

Talk about

The consensus of Haining entrepreneurs is that clean production is the foundation.

It is impossible to solve the problem of tannery sewage treatment without implementing clean production and achieving source control.

Zhou Yonggen, chairman of Haining Fu Sheng fur and leather Co., Ltd., said: "environmental protection must start with cleaner production. Chemical products can be balanced as long as they are balanced, not the more, the process control is more important than the end treatment.

Our experience is to use the least amount of chemicals to absorb the skin and to put too much material into the water. When the skin is full and run into the water, it will also increase the cost of pollution control. Two, if the sludge control is not done well, the cost behind it will be very high.

The factory is now independent of the pipeline and independent of the workshop, so as to realize fine management. The sewage can achieve the discharge of the standard. The chrome sludge from the solid waste can be reused and the waste gas is treated by photocatalyst technology. The whole process can achieve green production and recycle.

Since 2010, Haining tannery enterprises have eliminated 223 backward drums, update the main production equipment 141 sets and update 60 new overloaded drum. Compared with the traditional drum, the overloaded drum is 20% and the consumption of dyes and auxiliaries is reduced by 10%.

The sheepskin manufacturers imported machines, automatic spray bags, mortar and machine hair instead of traditional manual ash handling and manual pushing. All of the bags were recycled, and the amount of sulphur alkali and lime decreased by 20% and 10% respectively. The number of workers reduced by nearly 20% when workers' labor intensity and workers' working environment were reduced.

The automatic temperature regulation water supply system is applied to the main water consuming processes such as preparation, tanning, dyeing, and so on. By accurately measuring the water consumption, the extensive water consumption behavior is eliminated.

Equipped with more than 1000 yuan computer program automatic batching system, equipped with intelligent overload drum and other equipment, not only reduce material and water consumption by 10-20%, but also reduce labor consumption by 20%, and reduce the labor intensity of workers, eliminate human error in operation, ensure product quality is stable, and the batching system has reached the international advanced level.
