Today is World Oceans Day. 🌊 And we want to introduce you to five of its most beloved residents — and why they need our help.

Swipe to meet ocean creatures impacted by plastic pollution, and what we can all do to make things better for them. 👆

Because here at Mango Materials, we didn’t just build a better material for your backyard. We built it for every creature that calls the ocean home — big 🦭 and small 🐙.

Choosing products made from PHA — like the YOPP® Sandbox Toy Set — means choosing a material that biodegrades completely when eventually disposed of. No microplastics. No fragments. Nothing left behind in the waters these animals depend on.

Every small choice adds up. This World Oceans Day, we hope this one makes you smile — and think twice about the materials in your home. 🌱

Our CEO has been practicing this one for years. 😄
 
Poly-hydro-xy-al-kan-oh-ate — aka PHA — is the biobased material behind every YOPP® Sandbox Toy Set. Made by microorganisms, built for your backyard, and completely biodegradable when eventually disposed of.
 
Hard to say. Easy to love. 🌱

🌿 Did you know?
 
PHA has existed on Earth for hundreds of millions of years. Long before humans ever invented plastic.
 
Bacteria have been producing PHA naturally as an energy storage molecule since before dinosaurs roamed the Earth. We didn’t invent it. We just figured out how to work with what nature already made.
 
Pretty amazing, right?

We know. It’s a mouthful. But stick with us — because this hard-to-pronounce material might just be one of the most important things you learn about this year.
 
PHA is a biopolymer produced naturally by microorganisms. It performs like conventional plastic, biodegrades completely when disposed of, and leaves zero microplastics behind. In the ocean. In the soil. Nowhere it shouldn’t be.
 
It’s also what every YOPP® Sandbox toy set is made from.
 
Swipe through for 5 facts about PHA that are worth knowing — for you, your kids, and honestly anyone who’s ever thrown something away and wondered where it ends up. 👆

Every beach day starts with big sandcastle dreams and ends with sand everywhere. And we wouldn’t have it any other way. 🪣
 
This one’s for every family that’s ever packed up the car, driven to the beach, and watched their kids immediately sit down and start digging. We see you. We are you.
 
At Mango Materials, we believe the beach belongs to everyone, the sea lions, the sandpipers, and especially the tiny humans with very strong opinions about sandcastle architecture. 🏰
 
That’s why we made the YOPP® Sandbox set from PHA — a biobased material that biodegrades completely when eventually disposed of. (But more on that next week!) No microplastics left behind in Chonkers’ ocean. No guilt in your beach bag. Just really, really good digging. 🌊
 
Because beach days are the best days!
 
(We can’t help you with the sand in the car. That’s between you and the universe.)
