Recycling of milk beverage paper packaging for industrial application

Piles of waste milk beverage paper packaging, processed through a series of chemical and mechanical methods, and separated into plastic particles and aluminum powder. Recently, the reporter learned that Hangzhou Fulun Ecological Circulation Technology Development Co., Ltd. learned that new types of aluminum for milk beverage paper packaging Plastic separation technology has been successfully applied to industrial applications, increasing its value for recycling by about 30%. Shi Wanpeng, president of the China Packaging Federation, said that this has greatly expanded the recycling of waste milk beverage paper packaging and helped it to recycle.

At present, the annual use of aseptic composite paper packaging in China is approximately 400,000 tons, which is mainly used for packaging milk and beverages. The raw material for aseptic composite paper packaging is usually 75% cardboard, 15% polyethylene, and 5% aluminum foil.

Since 2007, a company in Shandong has teamed up with experts from Shandong Liaocheng University to jointly research and develop aluminum-plastic separation technology that suits China's national conditions under the strong support of packaging manufacturing company Tetra Pak. After two years of research and development and repeated debugging, aluminum-plastic separation technology has been successful, and Hangzhou Fulun Ecological Cycle Technology Development Co., Ltd. has officially entered into industrial production.

This aluminum-plastic separation technology adopts a semi-chemical and semi-mechanical method to separate the aluminum-plastic screening slag produced after extracting the pulp from the aseptic composite paper packaging, separating the aluminum foil from the plastic, and processing the aluminum foil into aluminum powder, which is made of plastic. Plastic particles. General Manager Yang Jun said that Fulun handles 10,000 tons of composite paper packaging each year and produces about 200 tons of aluminum-plastic screening slag every month. After the Shangma Aluminum-Plastics Separation Line, the recycling value of composite paper packaging increased by approximately 30%, and monthly sales revenue increased by 25%. Fulunn returned nearly 1.7 billion milk beverage paper packages in 2009. In recent years, it has been rated as a recycling economy demonstration enterprise in Hangzhou, an environmental protection education base in Hangzhou, and an advanced cleaner production unit in Fuyang City.

Shi Wanpeng pointed out that the total output value of China's packaging industry in 2008 has reached 860 billion yuan, ranking among the world's largest packaging countries, but the overall recycling rate of packaging waste is only 15% -20%. The Chinese packaging industry must establish a system that focuses on the efficient use of resources and recycling. Among them, the practical, efficient and environmentally friendly recycling technology is the key driver.

Shi Wanpeng said that the realization of industrial application of aluminum-plastic separation technology has greatly expanded the recycling of waste milk beverage paper packaging applications, so that recycling and recycling are profitable, will help the sustainable development of recycling industry, will make more and more More milk beverage paper packaging can be "rebirth."
