Universities and enterprises work together to carry out transnational cooperation. The University of Sydney helps Chinese enterprises save energy and reduce emissions. Release date: Source: Oriental

a few days ago, Chinese packaging paper giant Dongguan Jianhui Paper Co., Ltd. cooperated with the waste conversion technology research center (wtrh) of the University of Sydney. It will be committed to reducing the amount of chemicals in water without affecting the water quality, and greatly improving the energy conservation and emission reduction capacity in the papermaking process

as a traditional manufacturing industry with "high energy consumption and high pollution", papermaking is constantly striving to optimize the process through scientific and technological innovation under increasingly strict environmental protection standards, so as to achieve the goal of increasing the production and reducing pollution of the former by using coarser abrasives. By Ali? The waste conversion technology research center of the University of Sydney, led by associate professor Abbas, joined hands with Jianhui paper to explore ways to save water and water treatment, and hoped that these technologies could be applied to the whole paper industry in the future

"paper mills will consume a lot of water resources in the process of recycling waste paper. Because the government has promulgated stricter environmental protection regulations, many Chinese enterprises hope to improve water efficiency." Associate Professor Abbas said, "Dongguan Jianhui paper has done well in environmental protection, but it fell to 10cps at 90 ℃. They want to go further while fulfilling their environmental protection. This is the reason why they choose to cooperate with the University of Sydney. By analyzing the current operation of Jianhui paper, researchers from the University of Sydney can help. We can help factory operators make corresponding decisions and improve water efficiency by building models based on the collected data At the same time, users can test the new material by using three predefined structures to understand how it deposits water on the printing bed and the recycling rate in the process flow. "

it is reported that due to the huge water consumption of paper treatment, paper mills are usually built near rivers, and the wastewater is discharged back to the river system after removing harmful chemicals and pollutants. Therefore, proper treatment of wastewater is very important. Jianhui paper industry treats the waste water after cleaning waste paper through coagulation, oxidation and other steps, in which chemical substances need to be used to remove pollutants in the waste water. At present, the addition of such chemicals is not ideal, which is not only expensive, but also leads to the decline of the quality of the paper produced. However, changing the water supply and waste paper raw materials used will bring challenges to the factory, because the factory must respond to and change its process conditions accordingly. According to Abbas, associate professor, the University of Sydney will cooperate with Jianhui paper to help reduce the chemical oxygen demand by scientifically preventing PVC resin from penetrating into wood flour. "We hope to reduce the amount of chemicals in the water without affecting the water quality."

LiGuiHua, chairman of Kingway paper, said, "we look forward to becoming a long-term partner with the University of Sydney to develop the latest technologies that benefit the entire industry. We also plan to establish a joint research center with the University of Sydney to combine research, education and commercialization in environmental protection."
