What are the differences in recycling biodegradable plastics with a plastic crusher?
May 30, 2025| Recycling biodegradable plastics is an essential step in promoting environmental sustainability, and our Plastic Crusher plays a crucial role in this process. In this blog, we will delve into the differences in recycling biodegradable plastics with a Plastic Crusher compared to other methods, highlighting the unique advantages our machines bring to the table.
Understanding Biodegradable Plastics
Before we discuss the recycling process, it's important to understand what biodegradable plastics are. Biodegradable plastics are polymers that can be broken down by microorganisms into natural substances such as water, carbon dioxide, and biomass under specific environmental conditions. Unlike traditional plastics, which can persist in the environment for hundreds of years, biodegradable plastics offer a more eco - friendly alternative. There are two main types of biodegradable plastics: oxo - biodegradable plastics, which break down in the presence of oxygen and sunlight, and hydro - biodegradable plastics, which degrade in the presence of water and microorganisms.
Traditional Recycling Methods and Their Limitations
Traditional recycling methods for plastics often involve mechanical recycling, which typically includes steps like sorting, washing, shredding, melting, and re - pelletizing. However, when it comes to biodegradable plastics, these methods face several limitations.
Sorting biodegradable plastics from other types of plastics is a challenge. Since biodegradable plastics may have physical and chemical properties similar to those of conventional plastics, it can be difficult to separate them accurately using automated sorting systems. Moreover, when biodegradable plastics are mixed with traditional plastics during the recycling process, it can contaminate the recycled batch, reducing the quality of the final recycled product.
Another issue is the melting process. Biodegradable plastics have lower melting points compared to many traditional plastics. In a standard recycling plant, where high - temperature melting is commonly used, biodegradable plastics may degrade prematurely, releasing harmful by - products or losing their desired mechanical properties.
The Role of Our Plastic Crusher in Biodegradable Plastic Recycling
Our Plastic Crusher offers a more efficient and effective solution for recycling biodegradable plastics.
Size Reduction
The primary function of a plastic crusher is to reduce the size of the plastic waste. By breaking down large pieces of biodegradable plastics into smaller fragments, we increase the surface area of the plastic. This is crucial because a larger surface area allows microorganisms to access the plastic more easily during the biodegradation process.
When biodegradable plastics are fed into our crusher, the sharp blades cut the plastic into small, uniform pieces. This size reduction not only speeds up the biodegradation process but also makes subsequent handling and processing more manageable. The smaller pieces can be more easily transported and stored, and they can also be fed more evenly into other recycling equipment.
Separation Facilitation
Our Plastic Crusher also helps in the separation process. After size reduction, it becomes easier to separate biodegradable plastics from other types of waste. For example, the smaller plastic particles can be sieved more efficiently, as different materials will have different particle sizes and densities. This improves the purity of the biodegradable plastic fraction, leading to a higher - quality recycled product.
Gentle Processing
Unlike high - temperature melting processes, our Plastic Crusher uses mechanical force for size reduction. This gentle processing method ensures that the biodegradable plastics do not experience thermal degradation. As a result, the chemical structure and mechanical properties of the biodegradable plastics are better preserved, which is essential for producing high - quality recycled materials.
Compatibility with Other Recycling Equipment
Our Plastic Crusher can be seamlessly integrated with other recycling equipment to create a comprehensive recycling system.
For instance, after the plastic is crushed, it can be fed into an Industrial Shredder for further size reduction. The industrial shredder can break the plastic fragments into even smaller pieces, which are more suitable for certain biodegradation treatments.


An Auto Weighing Feeding System can also be used in conjunction with our plastic crusher. This system accurately measures the amount of crushed biodegradable plastic being fed into the next stage of the recycling process, ensuring a consistent and efficient operation.
Furthermore, to handle the dust generated during the crushing process, an Industrial Baghouse Dust Collectors can be installed. The dust collector captures the fine plastic particles and dust, preventing them from being released into the environment and maintaining a clean and safe working environment.
Economic and Environmental Benefits
Using our Plastic Crusher for recycling biodegradable plastics brings both economic and environmental benefits.
From an economic perspective, by improving the efficiency of the recycling process, our crusher can reduce the overall cost of biodegradable plastic recycling. The smaller, more uniform plastic particles produced by the crusher can be processed more quickly and with less energy consumption compared to large, irregular pieces of plastic. This means lower processing costs, which can translate into more competitive pricing for the recycled biodegradable plastic products.
Environmentally, by facilitating the proper recycling of biodegradable plastics, we help to reduce the amount of plastic waste sent to landfills or incinerators. Biodegradable plastics that are correctly recycled can be transformed into new products, reducing the demand for virgin plastics. This, in turn, conserves natural resources and reduces the carbon footprint associated with plastic production.
