Polystyrene: from pollutant to profit

Polystyrene(EPS), or Styrofoam, as it is commonly referred, has long been the bad guy of the recycling world. Though ideal for protecting and transporting fragile goods without added weight, its non-biodegradable polymers make it a major environmental pollutant that lingers in landfills, clogs waterways and storm drains, and litters land and sea.

EPS Life Cycle Assumption & Methodology

PRODUCT. The EPS insulation modeled has a density of 1.0 lb/ft3 and an R-Value of R-3.85 per inch. The study evaluated EPS board stock insulation with a value of R-4 and R-6. The results for R-6 provided a greater nominal return on investment than those for R-4 and a lesser percentage return.

RAW MATERIAL PRODUCTION. The production of EPS resin is modeled using the U.S. Life Cycle Index (LCI) Database and from Franklin Associates private LCI database for blowing agent and resin production. The brominated fire retardant commonly used represents about 0.7% by weight. As life cycle data for the fire retardant was not available, the entire weight was modeled as EPS. Continue reading

Waste Recovery and Recycled Content

It is important to note that recycled EPS can be categorized into two types of material:

1. Post Consumer refers to a material or finished product that has served its intended use and has been discarded for disposal or recovery, having
completed its life as a consumer item.

2. Post Industrial is recovered industrial and manufacturing materials that are diverted from municipal solid waste for the purpose of collection, recycling, and disposition. Continue reading

The steps to recycle EPS

The following steps are recommended to establish a new EPS packaging recovery programme.

1. Identify the quality and quantity of EPS in your waste stream

The first step in recycling EPS is to identify the quality and quantity of EPS in the waste stream, as this will influence the ability to market it. Polymer identification symbols are now frequently used to distinguish between different packaging types. The symbol for polystyrene and thus EPS is shown in Continue reading

EPS Handles The Environment With Care

• Prior to 1988, there was essentially no recovery of postconsumer polystyrene for recycling. Although the availability of polystyrene recycling programs varies by community, in 2004 more than 57 million pounds of polystyrene was recycled.

• The percentage of post-consumer polystyrene diverted from landfills, as a result of source reduction, re-use and recycling, increased from 0.8% in 1974 to 15.7% in 1997. Continue reading

Waste Reduction Options For EPS

There are four main waste reduction options for EPS packaging:

1. Reduce – refers to the reduction of natural resources used. By optimising pack design, moulders can reduce EPS usage, thus reducing environmental burden and cost.

Another simple re-use of the packaging is to grind it and use it as soil conditioner to improve drainage and aeration. EPS seed and pot-holding trays are often re-used in this way at garden centres.
