Why did Dunkin Donuts stop using Styrofoam cups?

The coffee and doughnut chain known as Dunkin’ says soon its New England stores will stop using coffee cups made of polystyrene foam; they cite environmental concerns. That likely means the end of double cupping – a coffee custom that’s especially popular in New England.

Who used Styrofoam first?

History. In the 1940s, researchers in Dow’s Chemical Physics Lab, led by Ray McIntire, found a way to make foamed polystyrene. They rediscovered a method first used by Swedish inventor Carl Georg Munters, and obtained an exclusive license to Munters’s patent in the United States.

When was Styrofoam widely used?

👉 For more insights, check out this resource.

First discovered in 1839 in Berlin, Styrofoam’s precursor—expanded polystyrene (EPS) foam—became immensely popular during World War II as an inexpensive building material for military aircrafts. Between 1939 and 1945, the rate of polystyrene production increased expotentially.

When did Dunkin Donuts stop using Styrofoam cups?

2020 I think we’ll all be caffeinated and A-OK! Original: February 27, 2018 4:28 p.m. In a move to make their company more eco-friendly, Dunkin’ Donuts announced plans today to eliminate all polystyrene foam cups from their restaurants around the world by 2020.

Why do coffee shops not use foam cups?

These chemicals can also seep into the food and drinks we store in foam containers, putting us at a greater risk for contracting these illnesses. That means each time we take a big swig of coffee out of that foam cup, or through that plastic lid, we may also be consuming styrene and other harmful toxins.

How safe are styrofoam cups?

Polystyrene foam cups contain styrene – a chemical compound that is increasingly suspect. Styrene isn’t known to leach out of hard plastics, but some evidence suggests that it can leach out of foam food containers and cups when food or drinks are hot – not when they’re cold.

Why is Styrofoam bad for you?

Styrene is the building block for Styrofoam, and the International Agency for Research on Cancer (IARC) lists styrene as a “probable carcinogen to humans”. And if that wasn’t bad enough, Styrofoam is commonly contaminated with flame-retardant chemicals that can leach into the environment and harm human health.

Does Styrofoam contribute to global warming?

Air Pollution Styrofoam is manufactured by using HFCs, or hydrofluorocarbons, which have negative impacts on the ozone layer and global warming.

Are Styrofoam cups toxic?

2. It leaches into food and drink. and heat, a Styrofoam container’s toxins (like benzene and styrene) seep into the contents. But even with cold or dry food, contact with Styrofoam is unhealthy.

Where did the idea of Styrofoam cups come from?

The earliest precursor to what we call the styrofoam cup was invented in Germany in the 19th century. Today, however, when we enjoy a hot drink that stays hot or a cold drink that stays cold, holding it in a hand that stays dry and at normal body temperature, we are actually using a different type of foamed plastic called polystyrene.

When was polystyrene first used in coffee cups?

This backgrounder will focus on the foam forms, since they have disproportional environmental impact. Polystyrene was discovered way back in 1839, was manufactured starting in the 1930s, then was first foamed in the 1940s, and first sold as coffee cups in the 1960s.

Who was the first person to invent styrofoam?

According to the 2000 publication “Polystyrene: synthesis, production and applications” by J.R. Wunsch, the first ancestor of Styrofoam was discovered by a chemist named Eduard Simon in 1839, in Germany. Simon distilled storax, derived from a tree, which created a “resinous solid” that he named styrol. Polystyrene.

What’s the difference between styrofoam and polystyrene cups?

Today, we refer to all polystyrene-type material as styrofoam; however, this term should be used only to refer to the material produced by Dow. Particularly, Styrofoam is a building insulation material produced by Dow that is distinct from the material that polystyrene cups are made of.

How do you make Styrofoam cups?

Instructions Break the styrofoam cups into small pieces and place them into a blender. Add 1 Tablespoon of Borax to ½ cup hot water and stir until dissolved and the water turns clear. Add ¼ cup white glue, ¼ cup warm water and 10 drops food colouring to a large freezer bag.

What size is a styrofoam cup?

The measurements of a styrofoam cup are as follows; top diameter: 7.7 mm. bottom diameter: 4.5 mm. height: 8.7 mm.

What is foam cup?

Foam cups offer insulation during transportation to keep your customers’ drinks hot or cold. Lids. Pair each cup with a compatible lid to ensure a snug fit that won’t leak or spill as you serve your customers drinks to-go.
