While small in size, microplastics have a massive impact, posing significant risks to ecosystems, wildlife, and potentially even human health.

At Sustai Market, we prioritize educating consumers about the risks of harmful ingredients like microplastics and providing safer, eco-friendly alternatives. Through our Sustai Score and Non-Toxic Badge, we empower you to make sustainable, informed choices. In this blog, we’ll delve into what microplastics are, their sources, and the alarming consequences they have on our planet.

What Are Microplastics?

Definition of Microplastics

Microplastics are tiny plastic particles that measure less than 5 millimeters in size. They are either manufactured intentionally (primary microplastics) or formed through the breakdown of larger plastic items (secondary microplastics).

• Primary Microplastics: These are manufactured for specific uses, such as microbeads in cosmetics and industrial abrasives.

• Secondary Microplastics: These result from the degradation of larger plastic items like bottles, bags, fishing nets, and other waste due to exposure to sunlight, wind, and water.

Why Are Microplastics a Concern?

Microplastics are a growing concern because they are:

• Pervasive: Found in every corner of the globe, from the depths of the ocean to the peaks of remote mountains.

• Persistent: They do not biodegrade easily, remaining in the environment for hundreds of years.

• Harmful: Microplastics pose a threat to ecosystems, marine life, and potentially human health.
