Trashed Styrofoam does not degrade easily, as it is made from non-renewable petroleum products. According to the Environmental Protection Agency, more than 2 million of the 3 million tons of Styrofoam products produced in the United States sit in landfills. Due to the vast amount of Styrofoam filling the landfills, researchers are motivated to explore better disposal solutions for Styrofoam. Continue reading
According to the National Bureau of Standards Center for Fire Research, burning landfills containing Styrofoam release 57 dangerous chemical byproducts into the air.
Sunlight creates harmful air pollutants from Styrofoam that are known as tropospheric ozone. The solar heating of the chlorofluorocarbons and hydrocarbons in Styrofoam also cause air pollution, contaminate landfills, and deplete the ozone layer. Continue reading

Styrofoam, plastic foam and other polystyrenes are designated as plastic No. 6, but many recycling programs that accept plastic No. 6 specifically exclude Styrofoam. EPS foams contain a lot of air, which is why they are good insulators. However, the extra air makes them hard to ship. Once the Styrofoam has been melted down and the air removed, little plastic is recovered compared to other polystyrenes such as those used in DVD cases. The resources required to ship and process the EPS offsets the environmental benefits of recycling to a greater degree than denser plastics. Continue reading
The crafting purposes of Styrofoam balls are largely varied. Styrofoam balls are spherical forms of polystyrene foam that come in sizes from one inch (2.54 cm) to eight inches (20.3 cm) in diameter. They are sturdy and can be cut to fit a project or can be used in conjunction with other Styrofoam shapes, such as blocks, cones, or rings to accomplish a variety of dimensional projects.
In the generic use of the term, Styrofoam has gotten a bad rap for its undesirable environmental impact as a non-biodegradable product. However, the Syrofoam balls are made from recycled extruded polystyrene. Examples of craft ideas for which Styrofoam balls are commonly used include science fair planetariums and other projects, Christmas tree ornaments and other holiday decorations, and artificial floral arrangements. There are, however, a plethora of other projects that could be created using Styrofoam balls and other shapes.
Styrofoam has a bulk density of between 10 – 80 kg/m3. The high volume and low weight nature of this waste has a significant impact on the overall costs of Styrofoam recycling, through high collection and transportation costs. With a large proportion of available waste arising from large retailers and producers, sorted at source, reverse logistics, i.e. filling returning lorries with Styrofoam waste can help reduce these costs, as can co-collecting separated waste with other industrial or trade recyclables and densification.
Only clean Styrofoam is usually requested and simple processing techniques are used to produce a granular, Styrofoam product; processing costs of € 100 have been reported. The cost range detailed, € 300 – 1,700 is not typical of collection systems. It also reflects private collection initiatives which may have to establish independent collection systems, however, the overall cost of the system is highly influenced by the collection method employed.
What exactly is Styrofoam? What are the different Styrofoam properties? In this article, we shall learn about the physical and chemical properties of Styrofoam.
Styrofoam, commonly known as ‘polystyrene’ is one of the most widely used type of plastics, is an inexpensive and hard plastic that use in a number of applications. The outside housing of computer, housings of most kitchen appliances, model cars and airplanes, toys, molded parts in cars are all made of Styrofoam. It is also made in the form of foam that is used for packaging and insulating.
