Baling plastic guide
According to Greenpeace, 2.4 million tons of plastic are recycled annually in the USA. Plastic balers compress sorted plastic into dense bales for transportation and storage. The plastic recycling industry bales materials to reduce transportation costs and storage space requirements. The plastic baling process follows these steps:
- Sorted plastic feeds into the baler’s hopper.
- Once the chamber is full, the baler compresses plastic to the desired density and weight.
- Operators use bale ties, or auto-tie balers tie plastic bales with baling wire.
- Finished bales are ejected from the baler and sent to recycling operations for processing.
Balers help remove plastic and other recyclables from the waste stream, promoting sustainability and the circular economy.
What is the plastic recycling process?
Besides baling, plastic undergoes the following recycling process:
- Collection and sorting. Plastic waste is collected and sorted at a waste material recovery facility. Different types of plastics are separated and prepared for recycling.
- Baling process. Sorted plastic waste is compressed into dense bales.
- Sale to processors. The plastic bales are sold to plastic processors or recycling facilities.
- Arrival at processing destination. Once at the processing facility, plastic bales are prepared for the recycling process. This may involve re-baling smaller bales into mill-size bales.
- Shredding and cleaning. The plastic bales are broken open and plastic waste is shredded into small pieces. These shreds are cleaned and filtered to remove impurities.
- Granulation. The cleaned, shredded plastic is melted and formed into pellets.
- Manufacturing new products. Plastic pellets are used to manufacture new products. Depending on the type of plastic, these recycled products range from new plastic bottles and containers to outdoor furniture, textiles, and building materials.
- Distribution and sale. Recycled products are distributed and sold to consumers, completing the recycling loop.
Not all plastic waste can be recycled due to contamination or the type of plastic.
Best baling wire for plastic
We carry several wire options for baling plastic materials. The best type of wire and wire gauge for baling plastic depends on whether you have a vertical or horizontal baler and whether it is automatic or manual tie. Storage conditions and duration also affect wire choice. Here are some of the best wire options for plastic:
- Single loop bale ties can be tied to different lengths to accommodate inconsistent bale sizes. They work with manual horizontal and vertical balers. We offer both black annealed and galvanized single loop bale ties. Galvanized bale ties provide enhanced abrasion resistance.
- Double loop bale ties are pre-cut to length and feature a loop (hook) at both ends. The double loop configuration accelerates the tying process, increasing productivity.
- Galvanized wire is less commonly used for baling plastic. But if your bales require long-term storage, hot-dip galvanization increases wire’s resistance to rust and corrosion to keep bales safe and secure.
- Black annealed wire feeds smoothly through the high-volume automatic baling machines commonly used in plastic recycling. The annealing process improves the wire’s ductility for baling expansive materials.
What types of plastic are recyclable?
There are seven types of plastics, each identified by a number inside the recycling symbol (resin identification code). Here's a brief overview of each type of plastic, its number, and its recyclability:
- PET or PETE (polyethylene terephthalate). This type of plastic is commonly found in beverage bottles, perishable food containers, and other plastic containers.PET bottles are some of the most easily recycled plastics.
- HDPE (high-density polyethylene). HDPE is used in milk cartons, shampoo bottles, and laundry detergent containers. It is also widely recyclable.
- PVC (polyvinyl chloride). PVC is used in pipes, kids' toys, plastic trays, and furniture. PVC products are not typically recyclable due to their composition.
- LDPE (low-density polyethylene). LDPE is used in grocery bags, plastic film, and bags that hold magazines, sliced bread loaves, and fresh produce. LDPE products can sometimes be recycled, but many municipalities do not accept this type of plastic in curbside recycling bins due to difficulties in recycling.
- PP (polypropylene). PP is used in food containers for products such as yogurt, sour cream, and margarine. It's also made into straws, rope, carpet, and bottle caps. PP products can sometimes be recycled, but the recycling rate is low due to challenges in achieving consistent recycling quality.
- PS (polystyrene). PS is used to make disposable coffee cups, packing peanuts, coolers, to-go food containers, and plastic cutlery. PS products can sometimes be recycled at specialist facilities, but the process is difficult and not widely practiced.
- Other. Any type of plastic that doesn't fit into the first six categories. Products stamped with a 7 are made out of multiple plastic types or out of other types of plastic. These products can sometimes be recycled, but it's not common due to the complexity of the materials. One recyclable example is ABS (acrylonitrile butadiene styrene).
The recyclability of these plastics depends on local recycling facilities and programs.
Benefits of recycling plastic
Plastic recycling benefits the environment, the economy, and society. Some benefits of plastic recycling include:
- Lower greenhouse gas emissions. Plastic recycling can help mitigate climate change by reducing the amount of energy needed for new plastic production.
- Reduced landfill waste. According to the EPA, recycling and composting prevented 94 million tons of material from reaching landfills in 2018.
- Natural resource conservation. The manufacture of new plastic products from recycled materials requires less energy and fewer raw materials than producing plastics from virgin resources.
- Protection of wildlife and ecosystems. Plastic recycling reduces the amount of plastic waste that ends up in oceans, rivers, and other natural habitats.
- Job creation and economic support. The recycling industry creates jobs in collection, processing, and manufacturing.
Plastic recycling is a step toward a more sustainable future. Active participation in plastic recycling programs and support for businesses that use recycled materials help minimize the environmental impact of plastic waste and preserve our planet for future generations.
