Why Choose Foam Products Instead of Paper?

One of the most obvious advantages polystyrene foam cups have over plastic-coated paper cups is that foam insulates better than paper. Paper cup users frequently use two cups together for hot beverages to protect their hands, use a cardboard sleeve, or wrap layers of napkins around the cup. “Double cupping” an average-weight polyethylene plastic-coated paperboard cup results in over twice as much solid waste by volume, over five times as much solid waste by weight, and nearly twice as much greenhouse gas emissions as the use of a single average-weight polystyrene cup.[i]

The environmental impact from the materials and energy used in making paper cups, as well as the emissions from incinerating or burying paper cups exceeds the impact of making and disposing of cups made of plastic foam.[ii]

All manufacturing processes have environmental consequences, just as all living creatures contribute, however minimally, to environmental degradation. The real answer on environmental impact comes from a comparative analysis with suitable alternative manufacturing processes.[iii]

 

Why Choose Single Service Products?

Single service foodservice products were developed to minimize exposure to bacteria and other foodborne pathogens. Today, Americans generate less packaging waste per person now than they did two decades ago.

As one study concluded, “while these data do not prove that using disposables actually prevents foodborne illness, the fact that reusables have a statistically higher level of microbial contamination than disposables favors the presumption that single service offers a measure of protection that would be missed if solid waste considerations barred them from use.”[iv]

Patrons of fast food restaurants, households with young children, hospitals concerned about the spread of foodborne disease, and school cafeterias and other restaurants that cannot accommodate a lunch or dinner crowd with reusables alone attest to the need for an alternative to permanentware. Add to this consideration the energy, water, and detergents used to wash permanentware and it seems clear that single service products have their place in modern life. Many organizations, such as Meals on Wheels and local food trucks, rely on the convenience, insulation properties, and high level of sanitation afforded by polystyrene food packaging in providing healthy food to their clients.
