How to recycle used milk cartons

Background Introduction

Milk cartons are usually made of composite materials such as paper, plastic, and aluminum foil, all of which have high recycling value. By recycling used milk cartons, these materials can be reused, thereby saving raw material resources and reducing the demand for new resources.

Recovery value

Waste milk cartons have significant value in resource reuse. The paper part can be converted into pulp for papermaking, the plastic part can be made into plastic pellets for manufacturing new plastic products, and the aluminum foil part can be used to manufacture aluminum foil products or other metal products. This recycling process not only saves raw materials, reduces energy consumption and pollutant emissions, but also promotes the recycling of resources.

Technological process

Crushing: Crush the collected waste milk cartons into smaller pieces for subsequent processing.

Cleaning: Clean the broken milk carton fragments to remove surface dirt, residue, etc., ensuring smooth separation process.

Separation:

Paper plastic separation: Using paper plastic separation mechanical equipment to separate the paper and plastic parts in the milk carton.

Aluminum plastic separation: For milk cartons containing aluminum foil, it is necessary to further separate the aluminum foil from the plastic.

Reprocessing:

Pulp processing: Processing the separated paper parts into pulp, which can be used to produce new paper or paper products.

Plastic granulation: Melting and granulating the separated plastic parts to produce plastic pellets, which can be used to produce new plastic products.

Aluminum foil recycling: The separated aluminum foil is recycled and can be used to produce aluminum foil products or other metal products.

Advantages of Recycling Machinery

Highly automated: The program has a high degree of automation, is easy to operate, and has stable performance, ensuring efficient and stable operation.

Efficient electrostatic separation: The electrostatic separation efficiency is as high as 99%, and the purity of the finished product is high, which can be directly sold and improve economic benefits.

Green and environmentally friendly: No wastewater discharge, achieving true green and environmentally friendly treatment, avoiding secondary pollution, and meeting environmental standards.

Energy saving and environmental protection: low power consumption, low noise, small footprint, and no dust pollution, achieving energy saving and emission reduction.

Wide applicability: With a wide range of sorting materials and fast sorting speed, it is suitable for the processing of various waste milk cartons and similar materials.

Advanced separation technology: using water-cooled and air-cooled vortex wheel mills for aluminum-plastic separation, making material separation more thorough and clean, adaptable to various material types, and improving reuse efficiency.
