Introduction

Styrofoam, commonly known as EPS (Expanded Polystyrene), is widely used in packaging, insulation, and various disposable containers. Despite its benefits, Styrofoam poses significant environmental challenges due to its non-biodegradable nature. Recycling machines have emerged as a vital solution, offering an efficient way to reduce Styrofoam waste. This article delineates the working principles of Styrofoam recycling machines and the innovative solutions provided by the Dongshen company.

Working of Styrofoam Recycling Machines

Styrofoam recycling machines are engineered to process EPS waste into reusable material. These machines undergo several stages to ensure efficient recycling and material restoration.

Collection and Preparation

EPS waste is sourced from various sectors, including packaging plants and consumer waste. The collected Styrofoam is sorted to remove contaminants and foreign materials. This preparation increases the efficiency of subsequent recycling processes.

Compaction Process

The compaction process is crucial in reducing the volume of Styrofoam waste. Machines apply pressure to compress the material, reducing its size by 90-95%, from approximately 500 kg/m³ to 50-25 kg/m³. This compacted form is easier to transport and further process.

Thermal Densification

Thermal densification involves heating the compacted EPS to reduce its volume further. The machine applies heat up to 180°C, which melts the Styrofoam, forming a denser, block-like material. This method ensures up to a 98% reduction in original volume, enhancing the efficiency of reuse and storage.

Pelletizing

The melted Styrofoam is then cooled and processed into small pellets. These pellets retain excellent material properties and are used as raw materials for manufacturing new plastic products. Adequate cooling post-thermal densification maintains the integrity of the pellets, ensuring practical reuse.
