How is Paper Recycled? Learn About the Recycling Process at Pratt Industries
Summary
TLDRThe video offers a detailed tour of a material recovery facility, showcasing the process of waste sorting and recycling. Trucks unload waste, which is then sorted by workers and machinery, including a disc screen and a trommel. Materials are separated into various streams and undergo quality checks. Cardboard is baled for transport to a paper mill, where it's recycled into new paper products. The facility plays a crucial role in Pratt Industries' commitment to providing 100% recycled packaging solutions.
Takeaways
- 🚚 Trucks arrive at the facility and are first weighed before unloading materials.
- 🔄 Materials are unloaded in a designated area and then loaded onto a conveyor system.
- 🚜 A front loader is used to move materials into an in-feed bunker for processing.
- 🌫️ A mister is utilized to manage dust during the material handling process.
- ♻️ Workers manually remove contaminants from the material on the pre-sort line.
- 📏 A disc screen is used to separate cardboard from other materials based on size.
- 🔭 Materials are further sorted into different streams: fines, medium, and large items.
- 🧲 Ferrous and aluminum materials are separated using magnets and eddy current separators.
- 🌬️ A blower sorter is employed to separate light materials from heavy ones.
- 🔎 Optical sorters are used to separate different types of plastics and cartons.
- 📦 Bales are compressed and stacked for transportation to be sold as commodities.
- 🌿 Mixed paper is sent to a paper mill to be recycled into 100% recycled paper products.
Q & A
What is the first step in the material recovery process at the Conyers facility?
-The first step is for trucks to arrive at the facility, where they stop on a scale to be weighed before proceeding to unload the materials onto the floor.
How is dust managed during the initial stages of material handling?
-A mister is used to help manage any dust as the materials are moved onto the first conveyor.
What is the function of the pre-sort line in the facility?
-The pre-sort line is where workers manually remove contaminants from the material, dropping them into bunkers below.
How is cardboard separated from other materials?
-Cardboard is separated from other materials using a disc screen, where it climbs the screen while the remaining material falls through.
What happens to the fines, medium-sized, and large items after the trommel separates them?
-Fines are conveyed past a cross-belt magnet to capture ferrous materials and an eddy current to capture aluminum. Medium-sized materials go to a ballistic sorter, while large items are conveyed to a blower sorter, which separates light and heavy materials.
What is the role of the blower sorter in the facility?
-The blower sorter separates light materials from heavy materials, which are then sent to separate sort lines where contaminants are removed.
How is mixed paper sorted and handled?
-Mixed paper is sorted using optical sorters in the light stream. After passing a final quality control check, it is loaded into a mixed paper truck.
What materials are separated by the optical sorters on the optical sort line?
-The optical sorters on the optical sort line separate number two HDPE (high-density polyethylene), number one PET (polyethylene terephthalate), and cartons.
What happens to the bales of sorted commodities after they are compressed?
-The bales of sorted commodities are stacked and loaded onto trailers to be sold as commodities.
What is unique about the handling of the mixed paper stream?
-The mixed paper stream is hauled directly to the Pratt paper mill, where it is re-pulped and made into 100% recycled paper. The recycled paper is then either converted into new cardboard or shipped to other Pratt facilities.
