ECO+ GRANDE®

Enhanced Quality

Improved strength provides easier handling and overall better perfomace.

Refined Formulation

No plantable components, eliminated amino acids & nutrients that affected durability.

Still Compostable

This improved container supports the sustainable practices that you value most. 

Our plant-powered Eco Grande™ and Eco Elite™ containers are made in Minnesota from corn grown in the U.S. They look and act like plastic, which makes them easy to work with for growers and retailers. This plastic-free Eco+ container will break down in the landfill hundreds of years faster than traditional plastic containers because Eco containers are made of 100% natural materials.

The Next Evolution

Thanks to your valuable feedback, we’ve made key improvements to deliver an even better product. The new Eco+ Grande® was already an award winner and now includes new features. Enhanced quality, greater durability, a stronger tag lock, and remain fully compostable. As with all Proven Winners® products, we are committed to ongoing refinement and improvement of the Eco+ Grande® container.
