Recycling Foam #6 Steps

Reasons for Recycling Foam #6

    1. Recycling foam #6 reduces solid waste
      Recycling foam #6 reduces the amount of solid waste that goes to our landfills and incinerators. Even though foam makes up less than 1% of municipal solid waste based on both weight and volume, every bit counts.
    2. Decrease our dependency on virgin resources
      Recycling foam reduces our dependency on virgin resources and conserves them for future generations. Plus, when you use recycled foam #6 cups instead of alternative materials, you conserve additional natural resources such as timber and water – another bonus for the environment!
    3. Prevent Pollution
      Recycling foam helps reduce the amount of pollution in our air which is generated by using virgin materials.
    4. Save energy
      Recycling foam #6 allows us to conserve energy that would otherwise be expended on manufacturing new materials.
    5. Protect the Earth’s atmosphere
      By reducing the amount of energy and materials used to make new products, recycling foam helps cut down on greenhouse gas emissions that contribute to climate change.
    6. Demonstrate sustainability

How to recycle PU foam?

Recently more and more people are looking for the solutions to recycle PU or TPU foam.

There are two types of PU foam in the market, one is sponge foam, other other is a cured foam or like rigid polyurethane foam sheet which is called TPU foam.

Sponge foam is too much memory. Hot melt is too smelly. Cold compaction won’t work as too much memory. But TPU cured foam which is rigid and brittle in nature. Our polyurethane foam compactor CU250, CU300 and CU360 would be a good machine to densify this kind of material. Using our foam compactor will help you save the transportation and landfill costs.

Choosing between Foam Compactor and Foam Shredder!

It is broadly believed that EPS (expanded polystyrene) foam waste is an unsafe, un-recyclable material. However, that is just a myth. Composed of 98% air and only 2% plastic, it is a recyclable material, which can be re-prepared, reshaped many a times.

Being an easily melting component, EPS can be melted, restructured, redesigned.

For the recycling of EPS foam, often seen with the packaging of delicate electronic goods, different types of machines – as foam shredder and foam compactor – are used.

If you are establishing a recycling plant for EPS waste management, which of these machines you would be arriving at?

Pore over the following passages that assist you on determining the right selection over this bafflement –

The purpose: There are two regular methods of EPS recycling – grinding and compressing. The compactor, as the name goes, compresses or compacts the foam into logs, that represent a great deal of convenience when it comes storing and transporting them. While the multi or single shaft shredder cuts the used foam in small sizes or beads.

Shredding – The expanded polystyrene foam can be used directly into the shredder machine. The appliance will cut and grind it into tiny beads. It is only the half-way process of recycling. It implies that the EPS is now ready for further recycling processes. However, these minuscule foam beads are also of a great use. Toy manufacturers and logistics companies purchase them to meet their product designing and packaging motives. These beads are also methodized in bean bags, cushions, etc.

Compacting – In a compactor machine, the small beads and pieces of scrap EPS are compressed into logs of different sizes and shapes, which are used for various industrial objectives. These machines come in different capacities, tonnage, and log size options. So, after the shredding and compression, EPS is re-melted and turned into lightweight logs, which are sent for reuse to different industries and small, mid and large size verticals.

Different machines are employed for these two foam recycling procedures. It doesn’t matter which machine you choose for recycling the scrap, it is important to get your machine from a reliable EPS waste recycling equipment manufacturer. For example, Runi, Harden, Hasswell. It ensures your plant’s productivity, efficiency, and additionally, cost-effectiveness.

Foam Recycling

Did you know that your foam trash can be turned into picture frames and surfboards? Recycled foam #6 is used to make a variety of everyday items, and recycling it is easy – once the foam products are collected, they are compacted into dense bricks and then converted into pellets that can be used to make new products. Visit to learn more about foam recycling and to find a recycling location near you. While you’re there, get inspired by stories from citizens who are committed to saving the planet, one recycled foam cup at a time!

Recycling foam is easy with programs like Dart Container’s CARE (Cups Are REcyclable) and Recycla-Pak. Whether you are a small business, a large corporation, a school, or an individual, Dart provides a convenient way of recycling, which protects the environment by reducing greenhouses gasses and landfill use. Recycling benefits you and your business by saving you money and stabilizing the economy. Some schools have experienced 20-40% savings on material collection fees.

CARE (Cups Are REcyclable)

Dart’s CARE program provides users with foam cup recycling collection devices. In order to make foam recycling cost-effective there are two key requirements:

  1. Separation of foam products from other non-foam products.
  2. Maximum consolidation of the collected foam cup products into the least amount of space.

The foam collected is then sent to the CARE program’s densifier. The densifier can compress 8,000 eight-ounce foam cups into a cylinder 15” tall and 15” diameter.

The densifier is designed specifically to break down the cellular structure of polystyrene foam through mechanical pressure. The densifer reduces the volume of loose foam products significantly, saving storage and transport space. The densifier is ideal for high-volume cafeterias, restaurants, or other food service operations using foam products.


The Dart Recycla-Pak program is a convenient and a cost-effective way for any size business to recycle foam cups. It’s simple – all you need to do is purchase a specially designed Recycla-Pak corrugated collection bin and you can start recycling foam cups right away.

The Recycla-Pak collection bin doubles as the shipping carton used to return the collected cups for recycling at a Dart or industry recycling facility. The bins are divided to keep the collected cups neatly stacked. The idea is to maximize the number of cups that will fit into the bin as well as discourage users from depositing anything but their used foam cups.RCP1

Ensuring that recyclable materials are disposed of responsibly is a daily occurrence in most homes, organizations and school campuses. Polystyrene foam products can be some of the items recycled. The EPS Industry Alliance, an advocacy group for individuals and organizations within the expanded polystyrene (EPS) industry, recently released a statement noting that the rate of EPS foam recycling has continually increased over the last twenty-plus years.1 EPS is often mistakenly referred to as Styrofoam®, a registered trademark of the Dow Chemical Company. Foam is the material that makes up the single-use foodservice items consumers prefer, such as hot beverage cups and take-away food containers. According to the EPS Industry Alliance, the rate of EPS recycling rose to 35 percent in the U.S. and Canada in 2013.1This figure represents a total 127.3 million pounds of post-commercial and post-consumer packaging, as well as post-industrial recovery foam that was processed and recycled over the last year.1This report confirms that the rate of recycling polystyrene foam is up roughly 5 percent year-after-year.1 The EPS Industry Alliance notes that consumer and commercial recycling represented a large amount of all recycled foam in 2013, stating, “When comparing rigid, durable polystyrene and other grade materials, EPS post-consumer and post-commercial recycling represent 47% of all post-use polystyrene recycled in the US and is one of the highest within the plastics family.”1 This increased rate reflects the continual growth of polystyrene foam recycling since 1991.1 One could relate the increased recycling rate of foam products to the influx of education regarding the properties of foam when compared to alternatives. For some consumers, there is still belief in the misconception that polystyrene foam is not a recyclable material, and that alternative single-use products are better for the environment. Several recent studies have proved that this is simply not true. Not only are foam items able to be recycled, they also require fewer resources to be produced than most alternatives. An article published by Christopher Bonanos of New York Magazine, notes, “It takes two and a half times as much energy to make a paper cup as it does to make a foam cup. Foam cups are also much lighter than paper cups, reducing the amount of fuel needed to ship them to the store and to cart them away as trash. Foam also produces a lot less manufacturing waste, because there are no paper offcuts to discard.”2 There is certainly more work to be done to educate individuals on the recyclability of polystyrene foam, but the increased rate of recycling within the U.S. and Canada would suggest that consumers are moving toward this understanding.

Polyurethane Foam Recycling Processes

Like other plastics, many polyurethane products can be recycled in various ways to remove them from the waste stream and to recapture the value inherent in the material. Most consumers are familiar with recycling plastic bottles and containers at curbside. Polyurethane recycling, on the other hand, usually happens elsewhere—on job sites, in industrial settings, during building demolition—and takes many forms, from relatively simple reuse to breaking down the material into its chemical constituents.

Polyurethane is recycled in two primary ways: mechanical recycling, in which the material is reused in its polymer form, and chemical recycling that takes the material back to its various chemical constituents.

Mechanical Recycling

  • Rebonded Flexible Foam—Rebonded flexible foam or “rebond” is made with pieces of chopped flexible polyurethane foam and a binder to create carpet underlay, sports mats, cushioning and similar products. Rebond has been used for decades and represents nearly 90 percent of the carpet underlay market in the United States.
  • Regrind or Powdering—Sometimes called powdering, regrind recycling takes polyurethane industrial trim or post-consumer parts and grinds them in various ways to produce a fine powder. The resultant powder is mixed with virgin materials to create new polyurethane foam or reaction injection molded (RIM) parts.
  • Adhesive Pressing/Particle Bonding—These two recycling processes use polyurethane from various applications, such as automobile parts, refrigerators and industrial trim, to create boards and moldings, often with very high recycled content. Used polyurethane parts are granulated and blended either with a powerful binder or polyurethane systems, then formed into boards or moldings under heat and pressure. The resulting products, analogous to particleboard made from wood waste, are used in sound proofing applications, furniture that is virtually impervious to water and flooring where elasticity is needed.
  • Compression Molding—This recycling process grinds reaction injection molded (RIM) and reinforced RIM parts into fine particles and then applies high pressure and heat in a mold, creating products with up to 100 percent recycled content and material properties that can be superior to virgin materials.

Chemical Recycling

  • Glycolysis—This process combines mixed industrial and post-consumer polyurethanes with diols at high heat, causing a chemical reaction that creates new polyols, a raw material used to make polyurethanes. These polyols can retain the properties and functionality of the original polyols and can be used in myriad applications.
  • Hydrolysis—This process creates a reaction between used polyurethanes and water, resulting in polyols and various intermediate chemicals. The polyols can be used as fuel and the intermediates as raw materials for polyurethane.
  • Pyrolysis—This process breaks down polyurethanes under an oxygen free environment to create gas and oils.
  • Hydrogenation—Similar to pyrolysis, hydrogenation creates gas and oil from used polyurethanes through a combination of heat and pressure and hydrogen.

Polyurethane Foam Recycling is Viable

The opportunity to generate additional revenues while eliminating costly waste removal has caught the attention of many home furnishings manufacturers, foam fabricators, carpet installers and other converts of flexible polyurethane foam. An easy product to recycle, flexible polyurethane foam scrap is now generating revenue for many end-users. The flexible polyurethane foam industry has made great strides in technology and end-use applications to address waste problems. By providing a “snapshot” of the opportunities for recycling in 1994, this bulletin is intended to assist manufacturers, production engineers, distributors, retailers, carpet installers, and others in the position to recover flexible polyurethane scrap. The following information examines the economic and environmental value of recovering and reusing scrap foam, with information on how your scrap can be used to generate revenue, offset raw material cost, and alleviate solid waste deposal problems.

Waste To Waves Recycling Program Gives Foam A Second, Ocean-Friendlier Life

Holiday shopping is upon us, and whether they do it in the stores or online, Americans are going to buy an absurd number of appliances, electronics, gizmos and gadgets in the run-up to Christmas.

With those gifts will come millions of pounds of packaging. While the cardboard box encasing your flat screens and Vitamixes typically can be recycled, the protective packaging foam (commonly known as “styrofoam”) that keeps those goodies snug usually can’t. As a result, most foam ends up in a landfill or, even worse, in the ocean.

Michael Stewart, co-founder of Sustainable Surf (a San Francisco nonprofit), discovered this sad reality over years of participating in California beach clean ups. Tired of seeing this type of plastic trash in and around the ocean, Stewart and Sustainable Surf’s other co-founder Kevin Whilden started the Waste to Wavesprogram, which aims to recycle styrofoam packaging back into new products — most notably, surfboards.
