Most restaurants today provide Styrofoam® to package your take out foods. In the United States, the word styrofoam® is often used as a generic term for expanded polystyrene foam, such as disposable coffee cups, coolers, or packaging material. These goods are typically white and constructed of expanded polystyrene beads, a petroleum product. Unrecycled polystyrene, which does not biodegrade, is often abundant in the outdoor environment, particularly along shores and waterways, and contributes to solid waste pollution. According to the Wikipedia, polystyrene can be recycled, a “6” under the familiar plastics numbering system.
Now, here’s the kicker. Even though polystyrene carries a #6 recycling symbol, the actual process required to recycle the material is often more costly than initial manufacturing. So what does that mean? Even if you carefully place all recyclable Styrofoam® into the appropriate recycling bins, it will likely still end up in a landfill…for thousands of years. When it does finally break down into its lowest basic form, it remains a major pollutant for wildlife and water supplies. Is it any wonder some cities are attempting to eliminate it? Seattle is leading the charge by becoming the first US city on record to completely ban Styrofoam® products.
What about typical clear plastic cups, utensils, or even paper goods? The clear plastic cups and utensils are still made from petroleum. Even though some of these items can be recycled, “contamination” by food products excludes them from the process and diverts them to the landfills anyway! Additionally, we are still supporting a non-sustainable industry…of which 80% is controlled by non-domestic companies. Paper goods are made from trees, a renewable resource, and they will eventually biodegrade without leaving toxic remnants. This potentially could be a sustainable industry, however, the Forest Stewardship Council reports that less than 10% of the paper used worldwide is from sustainable forests.
One of the newest sustainable alternatives are items manufactured from Polylactic Acid (PLA), a polymer derived from corn, also known as “corn plastic”. This material mimics clear plastic, yet does not biodegrade in a natural or landfill environment, but instead requires commercial composting, a service not available in many areas. Other items, including packing materials, are made from corn- or potato-starch. These begin degrading immediately upon contact with water.
Another alternative is Bagasse. This byproduct of sugar production resembles the appearance and properties of Styrofoam®. As with PLA, bagasse also biodegrades quickly in a commercial composting facility yet also breaks down in a landfill environment within a reasonable time frame. However, this presents its own set of problems. Landfills are not designed for their contents to rapidly break down, and waste management managers are concerned about such products creating “holes” in their fills after exactly that occurs.
So what’s the answer? Right now, there is no one solution. We will need to approach the sustainable disposables issue from a variety of paths. Perhaps one can embrace bagasse for utensils and coffee cups, PLA for clear plates and uninsulated glasses, and recycled/certified paper containers for take out purposes (Advantage: Cardboard containers don’t dissolve in the microwave!). While this remains non-ideal due to the shortage of composting facilities and valid concerns with corn products raising food prices, it is in everyone’s interest to start the transition away from the damaging disposables so prevalent in our lives today.
