PP Supersac Recycling Guide

Super sacks, also known as flexible intermediate bulk containers (FIBCs), are large woven bags that have become a popular solution for the storage, recycling and transportation of bulk materials. They are widely used in industries such as agriculture, mining, and manufacturing, and are known for their efficiency and durability. Proper disposal of super sacks are critical to minimize waste and protect the environment.

The Bulk Bag Recycling Process: A Step-by-Step Guide

Collection

At the start of the bulk bag recycling journey, it’s crucial to gather the recyclable bulk bags. One of the most efficient and cost-effective ways of collecting the bags is through compacted bales. The bags must be sorted into three categories, namely Grade A, B, and C, based on their cleanliness and color.

Sorting and Cleaning

Given the wide range of industries and applications that bulk bags serve, it’s necessary to sort the bags into groups and clean them thoroughly based on their contents. The bags may hold everything from sand to hazardous chemicals, so proper cleaning is vital.

Shredding

Once the bags have been cleaned and prepped, they move on to the shredder, which size reduces them to small flakes. This stage makes the subsequent processes easier to handle and is a key step in the recycling process.

Separation

The shredded material goes through a separation phase, where machines sort the plastic based on color, shape, size, light absorption, and melting point. They also eliminate any impurities or contaminants from the polymers. This is done through density separation and Infrared Sorting
technology.

Compounding

The final phase of the Super Sack recycling process is compounding, where the flake is melted into a finished product or reprocessed pellet. In this stage, extruders melt the shredded material at a temperature of approximately 240 degrees Celsius. The molten plastic is then forced through a screen to further filter out any remaining impurities.

Once absolutely clean and pure, the melted plastic is extruded into a strand, cooled, and chopped, creating pellets or granules of the plastic.

Challenges To Recycling PP Supersacks

Lack of Awareness

One of the biggest challenges facing PP Supersack recycling is the lack of awareness among users. Many people are unaware of the need to recycle these bags, or how to recycle them properly. This means that many bags end up in landfills, where they can harm the environment and wildlife.

Limited Recycling Infrastructure

Another challenge facing the recycling of Supersacs is the limited recycling infrastructure. Not all communities have access to recycling facilities, and those that do may not accept these bags.

Contamination of Recyclable Materials

Contamination is a major challenge facing Supersac recycling. When bags are contaminated with other materials, they can’t be recycled and must be sent to landfills.

Quality Control

Finally, quality control is a major challenge in the recycling of Supersacs. To ensure that the recycled material is of high quality, the recycling process must be carefully controlled. This includes proper sorting and cleaning, as well as monitoring the melting and compounding process to ensure that the final product meets the desired quality standards.

Conclusion

Supersacks are a versatile and efficient solution for material handling, but proper disposal and recycling are critical to minimize waste and protect the environment. There are many alternatives to landfilling Supersacs that are more environmentally friendly options for disposal, like reusing and recycling.

By working with an experienced recycler – individuals, and organizations can make a positive impact on the environment while reducing their bulk bag waste disposal costs. If you’d like to get a quote on your material – reach out to your local recycler.
