We don't produce sheets.
We design material solutions.
Sustaign is not a recycled plastic supplier. We are a circular material design studio.
Using 100% post-consumer plastic, we developed a refined production process that creates a distinctive marble-like structure. Tactile, architectural, and premium.
Includes pricing, color options and ordering process.
We collaborate to develop
01
Custom furniture
One-of-a-kind tables, counters, and shelving crafted from our signature recycled material, designed to your exact specifications.
02
Retail installations
Eye-catching displays and interior elements that will invite traffic into the store for an elevated in-store experience.
03
Hospitality interiors
Durable, design-forward surfaces for restaurants, hotels, and bars. Built to withstand high traffic without compromising aesthetics.
04
Office applications
Conference tables, reception desks, and workspace elements that bring circular design into professional environments.
05
Display systems
Modular exhibition and showroom systems that can be reconfigured, reused, and eventually recycled back into new material.

A unique production process.
A unique material identity.
We exclusively work with 100% post-consumer plastic. Through our proprietary refinement process, the material develops:
-
Depth and visual layering
-
Marble-like pattern variation
-
Premium tactile quality
-
Full color customization per project
No two surfaces are identical. Each project receives its own material signature.
Sustaign does not follow trends. We redefine waste into design value.

We are Sustaign
Our small-batch production and innovative techniques result in a distinctive range of sustainable panels and products. Each item is handcrafted from recycled plastic waste, ensuring both uniqueness and environmental responsibility.
We offer full personalization to meet your specific needs and preferences.
Sustaign adapts to your architectural vision.
