In order to achieve sustainable development, Linglong group carries out systemic exploration and practice and thus has formed three systems of industrial, manufacturing and technological innovation.
One is based on the industrial structure to develop circular economy and build the tire industry chain with the upstream and downstream industries and create a resource-saving and environmental protection enterprises. Relying on the tire industry park, totally more than 6 billion has been invested. Around the main tire industry, more than 10 main projects have been built including heating and power combination project, steel, cement, carbon black, reinforcing agent etc that has formed the circular economy chain on the core of tire production, on the guarantee of energy and on the assistance of raw material.
During surrounding environment of the development the harmonious development concept of recycling resource and advantages delivery and complementary has been realized. The heating and power combination project use the local low quality coal as the main fuel and adopts the advanced circulating fluidized bed boiler and extraction condensing turbine generator to generate power and heat, so that it has efficiently reduce the local pollution and sulfide gangue emissions.
The slag and fly ash produced by power plants have been used to produce cement that can be made into cement brick together using cement. Every year it can save 200,000 cubic meters of soil for making brick that indirectly protect the land resource.
Second, promoted by large project of energy-saving and environmental protection, to improve manufacturing standards, and to achieve recycling, efficient use and reuse. "Residual heat and pressure combined heat and power" project is using the carbon black production plant tail gas as fuel for steam production.
Annually it can save standard coal of 83,476 tons and reduce exhaust emissions of carbon black 150 000 Nm3 / h, reduce sulfur dioxide emissions of 912 tons, reduce carbon dioxide emissions of 61200 tons. reduce dust emissions of 672 tons and eliminate the exhaust of the environment pollution. "Integrated Radial Tire Innovation for Saving project has developed the new technology of temperature changing and curing temperature changing that can improve the single curing press efficiency by 8 to 10%, and annually can save 96,600 tons water, save 336 million tons of steam, save 39,433,000 hilowatt-hour power, save natural rubber and synthetic rubber of 2.
1 thousand tons and save capital of 51.935 million yuan.
Third, relying on research and innovation, to deeply perform the performance research, to create high-end products and to meet the environment protection and energy market trends: for example the rolling resistance study can reduce the energy consumption. Tire fuel consumption caused by the tire is up to 20% of cars tatal fuel consumption while the buses can reach 30%.
Every reduced 20%, of tire rolling resistance, the carbon dioxide emissions within 100 km can be reduced on 400 grams, In the company development place, the rolling resistance with relevant tire can be reduced by 30% that has meet the requirement for supporting the world-class auto plant requirements and can reduce fuel consumption by about 5%, and reduce carbon dioxide emissions by 600 grams with 100 km.
This year, two products have obtained the fuel-efficient tires Award. Thefirst domestic indoor noise laboratory has been built and the comprehensive study has been made on the tire performance of different structures. At the same time handed with the environmentally friendly tires and meet th internation environmental requirements, the company actively adopt new technology, new materials to study environmental protection tires that have passed the product testing by the international authorities, rWithin tires 8 polycyclic aromatic hydrocarbons (PAHs) content is not higher than 5ppm, 15 types of high interest material content is not more than 0.
1 % that have been in accordance with EU REACH regulations.
