In the case of paper vs.
Jennifer Killinger Email: PLA alternatives, primarily due to polystyrene foam's much lower weight. The polystyrene foam products create less, similar or more solid waste by volume than alternatives depending on the product and its weight, according to the study, and greenhouse gas emission comparisons vary widely, based on uncertainties over whether paper-based products degrade after disposal.
The life-cycle inventory and greenhouse gas emissions study 1 compares average-weight polystyrene foam, paperboard and PLA cups used for hot 16 ounce and cold 32 ounce drinks, 9-inch dinner plates and "clamshell" sandwich containers.
The peer-reviewed paper updates a study and incorporates additional data, most notably on greenhouse gas emissions following disposal. Polystyrene foam products consume significantly less energy than the alternatives-half as much as wax-coated paperboard cups and one-third as much as PLA clamshells.
Polystyrene foam products use significantly less water than the alternatives-up to four times less than PLA clamshells. Polystyrene foam products create significantly less solid waste by weight than the alternatives-up to five times less than paperboard and PLA products.
Comparisons by volume vary widely: Polystyrene foam cups for hot drinks create less waste by volume than the alternatives-significantly less than paperboard cups with corrugated sleeves used for insulation. Polystyrene foam cups for cold drinks create similar waste by volume as plastic coated paperboard cups and significantly less than wax coated paperboard and PLA cups.

Paper Cups vs. Styrofoam Cups It’s a common sight to see people walking around carrying coffee in paper or Styrofoam cups. The insulative values of paper and Styrofoam aren't that different, but Styrofoam cups generally are much thicker than paper ones, so they keep your coffee hot longer. Most paper cups are lined with a thin layer of wax, which makes the cup difficult to recycle. Finding a breakthrough in recycling could change the balance of power in the polystyrene-paper.
Heavy duty polystyrene foam plates produce more solid waste by volume than the alternatives, while lighter duty polystyrene foam plates create similar waste by volume as the paperboard counterparts.
Polystyrene foam clamshells create slightly more waste by volume than paperboard clamshells and half the waste by volume of PLA clamshells.
Polystyrene foam products generate slightly more greenhouse gas emissions than PLA products, expressed as net CO 2 equivalents see note below. If paperboard products do not degrade after disposal, they store carbon and generate fewer greenhouse gas emissions than polystyrene foam products; however, if paperboard products degrade to the maximum extent, they generate more greenhouse gas emissions than polystyrene foam products, so comparisons of greenhouse gas emissions vary widely depending on assumptions about the degradation of paperboard products.
Although PLA is corn-based, the study notes: For more information on this new study, please visit www. Emissions of all greenhouse gases for each system are expressed on the basis of net CO 2 equivalents, using each substance's net global warming potential relative to carbon dioxide CO 2.
For example, since methane has a higher global warming potential than CO 2each pound of methane released makes a larger contribution to global warming impacts than a pound of CO 2.
The study results are calculated based on the average weight of the various products. The study's authors note "uncertainty" in the water use results due to lack of clarity over how water use data on different materials were derived.
The authors note that post-disposal "greenhouse gas results [are] more uncertain than other emissions data" based on uncertainties over whether paper-based products degrade after disposal. They also highlight the lack of data on actual degradation of coated paperboard foodservice products and point out that "results for paperboard products vary considerably depending on assumptions about decomposition.

When comparing paper and Styrofoam cups, the eco-friendliest may surprise you.
If you are like me, you would guess a paper cup is much more eco-friendly then its evil step sibling, the Styrofoam cup. However, in many cases, a Styrofoam cup is the greener option.
