Baling metals guide

According to Statista, the United States recycled 51.9 million metric tons of metal scrap in 2021. Metals such as steel and aluminum have near-infinite recyclability, making metal recycling an important aspect of the recycling industry.

The baling process reduces transportation costs and storage space requirements for scrap metal recyclers. The metal baling process follows these steps:

  1. Sorted metals feed into the baler’s hopper.
  2. Once the bale chamber is full, the baler compresses the metal to the desired density and weight.
  3. Operators use bale ties or auto-tie balers secure the bales with baling wire.
  4. Finished bales are ejected from the baler machine and sent to recycling centers for processing.

Industrial balers help remove metal and other recyclables from the waste stream, promoting the circular economy and responsible waste management practices.

What is the metal recycling process?

The lifecycle of recycled metal involves a series of steps that transform scrap metal into new products. Here is a detailed step-by-step process:

  1. Collection: scrap metal is collected from households, businesses, construction sites, manufacturing facilities, and other sites.
  2. Sorting and separation: at the recycling facility, the scrap metal is sorted into different categories based on the type of metal, such as ferrous (containing iron) and non-ferrous metals (such as aluminum and copper). This can involve manual sorting conveyors, magnetic separators, or other machinery.
  3. Processing and shredding: large metal items are processed to remove non-metal components, such as plastics or glass. The metal is then shredded into smaller pieces to facilitate melting.
  4. Melting and purification: shredded metal is melted in a furnace. During melting, impurities are removed by burning, electrolysis, or other methods.
  5. Refining and alloying: some metals require refining or alloying to achieve desired properties. For example, aluminum might be alloyed with other metals to enhance its strength and durability.
  6. Casting: the purified metal is formed into specific shapes, such as ingots, bars, or sheets, depending on its intended use.
  7. Rolling or extrusion: metals such as steel and aluminum may undergo additional processing through rolling or extrusion to achieve specific thicknesses or complex shapes.
  8. Manufacturing: processed metal is used as raw material to manufacture new products.
  9. Distribution and reuse: newly manufactured products are distributed. When these products reach the end of their useful life, they can be recycled again, closing the recycling loop and beginning the process anew.

The near-infinite recyclability of most metals makes them important components of sustainable manufacturing practices.

Best baling wire for metals

We carry several wire options for baling metal. The best type of wire and wire gauge for baling metal depends on whether you have a vertical or horizontal balerand whether it is automatic or manual tie. Storage conditions and duration also affect wire choice. Here are some of the best options:

  • High-tensile galvanized wire can secure heavy, dense bales of scrap metal. Galvanization adds a layer of zinc that protects the wire from abrasive contact with scrap metal.
  • Galvanized wire can withstand the corrosion and abrasion that occur while scrap metal is being stored for long periods or outdoors.
  • Black annealed wire feeds smoothly through high-volume automatic balers that are commonly used in metal recycling. The annealing process improves the wire’s ductility for conforming to oddly shaped metal bales.
  • 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.
  • 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.

What types of metal are recyclable?

Most types of metal are recyclable, including:

  • Steel/iron is highly recyclable. Many steel mills use recycled scrap steel to produce new steel products. Steel can be recycled repeatedly without losing its strength or quality. Common steel recyclables include appliances, furniture, automotive parts, and baling wire.
  • Aluminum is one of the most commonly recycled non-ferrous metals. Less energy is required to recycle aluminum than to extract new aluminum, making it an economically and environmentally viable solution. Common aluminum items recycled include beverage cans, foil, and other household items.
  • Copper is a valuable non-ferrous metal that is commonly recycled. Copper can be melted down and reused without losing its strength or quality. Common copper recyclables include wiring, plumbing, and electronic components.
  • Other metals, such as gold and silver, have been recycled for thousands of years due to their high value. Brass and bronze, which are copper alloys, can also be recycled. Other commonly recycled metals include zinc, tin, and nickel, which are found in numerous household and industrial items.

Benefits of recycling metals

Some of the benefits of recycling metals include:

  • Metals can be recycled repeatedly without degrading
  • Require less energy and environmentally damaging processes
  • Reduced greenhouse gas emissions
  • Recycled metals are more cost-effective to produce than metals made from virgin materials
  • The metal recycling industry employs over a million workers in the US and generates significant economic activity
  • Recycling scrap metal frees up space in landfills


Sustainability depends on recycling metals and other materials. Active participation in metal recycling programs and support for businesses that use recycled metals help minimize the environmental impact of metal production and waste.
