Carbon-Negative Additives

Sustainable Rubber. Reimagined.

Hundreds of products are made from rubber. But thousands of products use elastomers to increase impact and toughness properties. Natural fiber additives have successfully been used in rubber applications for decades.

  • Reduce the Cost, Weight, and Carbon Footprint of Rubber
  • Lead Your Industry In Sustainable Material Innovation
One Material. Infinite Applications.

Natural Fiber Filled Rubber

Heartland works alongside brands and suppliers that use rubber in various applications.

Rubber is used in applications like thermoplastic elastomers (TPEs), ethylene propylene diene monomer (EPDMs), and styrene butadiene rubber (SBRs). Natural, neoprene, silicone, and nitrile rubber are also materials that can benefit from engineered natural fiber additives. 

No Retooling Costs

For Rubber Suppliers

Heartland supplies lower-carbon-footprint materials to help manufacturers create stronger, lighter, cheaper, and more sustainable products.

Augmenting Mined & Synthetic Materials

Unlocking The Sustainable Future We Need And Deserve

Heartland's materials replace and augment additives like talc and carbon black.

We work with global brands and their suppliers to predictably reduce the carbon footprint of everyday products without any retooling costs.

Your Sustainability Partner

Throughout The Supply Chain


Heartland partners with corn, wheat, and soy farmers to embed industrial hemp into their crop rotation. Our USDA Grant has given us unique insights into industrial hemp farming, regenerative agriculture, and carbon sequestration.


Heartland partners with plastic compounders to augment talc, calcium, and glass without any retooling costs. Our Imperium masterbatch solves dust, flammability, bonding, and bulk density problems typically associated with bio-based additives.


Heartland partners with plastic converters to ensure the hemp-filled resin is processed properly. Our team works alongside component part manufacturers to process natural fiber-filled plastic with the same molds used today.


Heartland is the sustainability partner for brands on their journey to reduce their carbon footprint. Our team helps create stakeholder alignment so companies can effectively communicate the value of sustainable material innovation.
