9 Ways to Reduce Plastic Waste in the Ocean

Small actions, big impact – together against the plastic tide

Why Plastic Waste Is a Global Problem

Plastic waste is one of the biggest environmental challenges of our time. Every year, millions of tons of plastic end up in our seas and oceans. It endangers marine life, destroys ecosystems, and returns to us as microplastics in our food chain.

As part of Plastic Free July, we at PURELEI want to raise awareness and take action together with you. Every step counts to keep trash out of the ocean.

What Are Garbage Patches in the Ocean?

You’ve probably heard of the huge “trash islands” floating in the sea. Technically, they’re called garbage patches made of plastic waste. These massive accumulations of debris are formed by ocean currents and can reach depths of up to 30 meters. They consist not only of visible bottles and bags but also of microscopic plastic particles and synthetic materials that barely decompose.

There are currently five major garbage gyres in the world’s oceans — they’re a stark reminder of how urgently we need to reduce our plastic use and ocean pollution.

Plastic in the Ocean and Its Impact on Marine Life

The effects of plastic waste in the oceans are life-threatening for many animals. Seabirds and turtles mistake plastic for food and can starve as a result. Dolphins and fish often get tangled in nets or plastic debris, leading to severe injuries or even death.

Shipping and fishing also contribute to ocean pollution when waste or wastewater is discharged into the sea. Over time, plastic breaks down into microplastics, making the problem even worse — these tiny particles are eaten by marine life and make their way into the entire food chain.

9 Easy Ways to Reduce Plastic Waste and the Plastic Tide

1. Reusable Bottles & Cups

Say no to single-use plastic and choose durable alternatives made of stainless steel or glass. Yes, coffee-to-go is great, but disposable cups are so easy to avoid with projects like Recup. Keep an eye out — many cafés and restaurants are Recup partners.

2. Cloth Bags Instead of Plastic Bags

Always handy, always sustainable — that’s how you can avoid tons of plastic while shopping that might otherwise end up in the ocean. The same goes for produce bags: go unpackaged whenever possible since those plastic bags usually end up in the trash right after you get home.

3. Sustainable Straws

Whether made of stainless steel, bamboo, or even edible materials — there are plenty of alternatives to plastic straws.

4. Spread Awareness About Plastic

Talk with family and friends about plastic pollution in the oceans and rivers and the impact it has on the planet. Share documentaries, posts, and info on social media — education is key.

5. Support Clean-Up Initiatives

Whether it’s a beach clean-up or a local trash collection event — it’s fun together and makes a real difference. Waste belongs in the right place, not in nature. You can also check out organizations like WWF to learn more about their ocean protection efforts.

6. Donate to Environmental Organizations

Support initiatives like Sustainable Coastlines Hawaii or WWF, which actively fight against ocean plastic pollution.

7. Go Vintage Instead of Buying New

Secondhand and antique items are not only usually plastic-free but also unique. Search for a local flea market — perfect for a relaxed Sunday outing.

8. Plan Sustainable Parties

Skip balloons, confetti, and plastic decorations — there are many creative, eco-friendly alternatives that are just as festive.

9. Choose Clothes Consciously

Many textiles contain polyester or Lycra, which release microplastics when washed. Go for natural fibers like cotton, linen, or Tencel instead.
