What is EPS, and 9 alternatives to styrofoam?

Expanded Polystyrene, i.e., EPS, is a rigid, closed-cell, thermoplastic foam material made from solid polystyrene, polymerized from styrene monomer, and includes an expansion gas (pentane) dissolved within the polystyrene bead.

EPS beads are made of polystyrene and have small amounts of gas inside them. The gas expands and forms closed cells when heat is applied in steam. These expanded cells take up about 40 times the volume of the original bead. Using heat to a mold allows large EPS blocks to be molded into specific shapes.

HISTORY

The commercial development of polystyrene began in Germany in 1929, with US firm Dow Chemical Co. beginning production around 1935.

Polystyrene foam was used extensively in Germany and the USA during the Second World War. However, it was not widely introduced until 1954, when Dow Chemical Co. began marketing it under the brand name “Styrofoam.”

Dow scientist Ray McIntire invented ‘Styrofoam’ while trying to create a new rubber by combining styrene and isobutylene. Though it was an accident, he made a foam that is 30 times lighter and comparatively more flexible than polystyrene.

PROPERTIES

EPS can be molded in a spectrum of densities from as low as 12kg/m3 up to 50kg/m3, with the resultant properties, such as compressive strength, defined by the manufactured density.

Expanded Polystyrene is typically water resistant, challenging, and gives very high impact resistance. The air-filled structure has long-term stable thermal conductivity, is non-toxic, and is chemically inert.  

Due to its plastic nature, Fungi and bacteria cannot grow on EPS due to their properties.  

PACKAGING

EPS is made of 98% air and is one of the lightest packaging materials available. It adds little weight to packaging, reducing transport costs and fuel emissions.

It is also beneficial because it can be marked with specific content like company logos. Labeling can also be attached directly to the packaging.

Polystyrene foam is an ideal packaging for many applications because it is rigid and has outstanding impact resistance and shock absorbency. It protects all electrical components, from mobile phones to fridge freezers.

EPS has a lower carbon footprint than many other packaging materials today, making it a more sustainable option. However, we still need to find an alternative to styrofoam.

How Does Styrofoam Affect the Environment?

Styrofoam is made from petroleum products, so it is not environmentally friendly. Styrofoam can take centuries to decompose, releasing toxins into the environment during that time. In addition, Styrofoam is often litter, which can harm animals if they ingest it. Some alternatives to Styrofoam are more environmentally friendly, such as foam peanuts, biodegradable styrofoam, and eco-friendly styrofoam.

#1 Biodegradable Peanuts Starch

What are biodegradable peanuts made of?

Biodegradable packing peanuts are made from natural, non-toxic corn starch or wheat sources. It can add packing material to compost piles. While they are non-toxic or safe if accidentally eaten, the nutritional value has been removed from these items’ starch.

Biodegradable Peanuts Starch, What is EPS, and 9 alternatives to styrofoam?

Before the development of biodegradable peanuts, styrofoam peanuts were available. It was developed and patented by Tektronix Inc. and made commercially available Circa 1965 by Dow Chemical. First made from 100% virgin polystyrene resin, peanuts made from 100% recycled polystyrene have been commercially feasible since the mid-90s.

The usage is the same as bubble wrap to fill the void in the container or boxes and be the best sustainable alternative to bubble wrap. Many companies give the feasibility open to the consumers, features such as

  • The packing peanuts can decompose in water, leaving no toxic waste, and also, it is FDA compliant.
  • There is Static-free organic starch.
  • It dispenses and vacuums like traditional peanuts.

Biodegradable packing peanuts are made from natural, non-toxic sources, such as wheat and corn starch. It is dissolved in water and thrown into compost piles after a single use. Also, biodegradable foam peanuts do not have an electrostatic charge, meaning they will not stick to clothes.
