How Long Does it Take for Chewing Gum to Decompose? And How Can We Reduce its Environmental Impact?

Chewing gum is a ubiquitous part of our daily lives. We chew it for fresh breath, to satisfy a sweet craving, or simply out of habit. But what happens to chewing gum after we're done with it?

The Decomposability of Chewing Gum

How long does it take for chewing gum to decompose? The answer depends on several factors, including the type of gum, the environmental conditions, and the presence of bacteria. Natural gums, such as those made from chicle, can take several years to decompose. Synthetic gums, on the other hand, can take decades or even centuries.

This is because synthetic gums are made from non-biodegradable materials, such as polyethylene and polypropylene. These materials are resistant to bacterial breakdown, which means they can persist in the environment for a long time.

Type of Gum	Decomposition Time
Natural gum (chicle)	5-10 years
Synthetic gum (polyethylene)	20-50 years
Synthetic gum (polypropylene)	100+ years

The Environmental Impact of Chewing Gum

The long decomposition time of chewing gum has a significant environmental impact. Chewing gum litter is a common sight in public spaces, such as parks, sidewalks, and beaches. It can also end up in waterways, where it can harm marine life.

According to the Gum Litter Task Force, chewing gum litter costs taxpayers millions of dollars each year to clean up. It also poses a threat to wildlife, as birds and other animals can mistake it for food and ingest it.
