How to dispose of end-of-life agricultural mulch films?

In modern agriculture, the use of agricultural mulch films has significantly improved agricultural benefits. However, as beneficial as these films are, their disposal has become a growing environmental concern. With the increasing accumulation of end-of-life waste agricultural films, it's crucial to explore sustainable recycling methods.

One effective solution to the disposal of end-of-life agricultural mulch films is the use of waste plastic recycling pyrolysis machines. These machines can efficiently convert various waste plastic materials, including agricultural mulch films, into valuable resources such as fuel oil, carbon black and syn-gas, which can be reused in various industrial applications. In this article, we'll explain how this process works and why it's a viable option for handling agricultural film waste.

End-of-Life Agricultural Mulch Films Recycling Pyrolysis Process

Agricultural mulch films are primarily composed of polyethylene (PE) and polypropylene (PP). When these films reach the end of their lifecycle, they become waste that can take hundreds of years to degrade, leading to serious environmental pollution. However, both materials are waste plastics with high oil content.

The most effective way to dispose of and recycle waste agricultural mulch films is through the pyrolysis process for high profits. Pyrolysis is a thermal decomposition process that breaks down these plastic waste materials into valuable byproducts like fuel oil, carbon black, and combustible gases. Here's an overview of the pyrolysis process for recycling agricultural mulch films:

Agricultural mulch films recycling pyrolysis process

1. Feeding the Waste into the Reactor

The first step involves feeding the waste agricultural mulch films into the pyrolysis reactor. This step typically takes 2-3 workers 3-4 hours to fill a reactor with a daily processing capacity of 15 tons. If an automatic feeder is used, the feeding process may require 2 workers and can take around 1.5 to 2 hours, which helps streamline the operation and enhance efficiency.

2. Pyrolysis Process

Once the waste agricultural mulch films are loaded into the reactor, the pyrolysis process begins. The reactor of waste plastic recycling pyrolysis machine is heated using an oil burner until the temperature reaches 200-400°C. As the temperature rises, the plastics break down, releasing oil vapors that are extracted for further processing.

3. Condensation and Oil Collection

After pyrolysis, the next step is the condensation of the oil vapors. Our pyrolysis system is equipped with a highly efficient cooling system to condense the oil vapors into liquid fuel oil. The pyrolysis oil cooling system includes:

·Two vertical condensers for initial cooling of the oil vapors.

·One oil-water separator to separate the oil from any water content.

·Two horizontal condensers that offer the largest cooling surface area, ensuring efficient condensation and high-quality oil output.

·Two condensation towers to further refine and separate the oil.

This multi-stage cooling process ensures that the plastic pyrolysis oil extracted from waste agricultural mulch films is effectively condensed, while all condensers use circulating cooling water, ensuring zero wastewater discharge and contributing to an eco-friendly operation.

4. Final Product

Once the cooling and condensation process is complete, the collected fuel oil is separated into different tanks. This plastic pyrolysis fuel oil has high calorific value, can be used as an energy source for various industrial applications, such as heating boilers and furnaces of steel/glass/china/brick making factories, creating a circular economy by turning waste into valuable products.
