What is Rotational Moulding Recycling ?

Material Recycling:  This can include the recycling of scrap plastic generated during the manufacturing process, as well as the recycling of end-of-life products made through rotational moulding. The plastic can be reprocessed and reused to create new products, reducing waste and conserving resources.

Closed-Loop Systems: Some manufacturers implement closed-loop systems where the plastic materials used in production are collected, processed, and reused within the same manufacturing cycle. This approach minimizes waste and improves sustainability.

What is MDPE ?

MDPE, or Medium-Density Polyethylene, is a widely used material in the rotomoulding industry due to its unique properties that cater to specific manufacturing needs.



Key Characteristics for Rotomoulding:


  • Good Flow Characteristics: MDPE has excellent flow properties, allowing for even distribution during the rotomoulding process, which results in consistent wall thickness in the final product.


  • Impact Resistance: Its high impact resistance makes MDPE ideal for producing durable items that can withstand rough handling and environmental stress.


  • Chemical Resistance: MDPE is resistant to a variety of chemicals, making it suitable for applications involving storage and transport of chemicals, water, and other substances.


  • Flexibility and Toughness: The material offers a good balance of flexibility and toughness, which is essential for products that require some degree of bending without breaking.


Design for Recycling: When designing products for rotational moulding, manufacturers can consider how easily the materials can be recycled at the end of the product's lifecycle. This includes avoiding the use of mixed materials that are difficult to separate during recycling.

Environmental Impact: Recycling rotational moulded products can significantly reduce the environmental impact associated with plastic waste, as it lowers the need for virgin plastic production and decreases landfill contributions.

Overall, rotational mould recycling aims to promote sustainability in the plastic manufacturing industry by minimizing waste and encouraging the reuse of materials.

Applications in Rotomoulding:


  • Storage Tanks: MDPE is commonly used to create large storage tanks for water, chemicals, and other liquids due to its durability and resistance to corrosion.


  • Containers and Bins: It is ideal for manufacturing bins, pallets, and containers that require lightweight yet strong materials for commercial and industrial use.


  • Playground Equipment: The impact resistance and safety features of MDPE make it a popular choice for outdoor play structures and equipment.


  • Custom Products: The versatility of MDPE allows for the design and production of custom-shaped products tailored to specific industry needs.




In summary, MDPE's properties make it a preferred choice in the rotomoulding industry, providing manufacturers with the ability to produce high-quality, durable products that meet diverse applications.
