Globally, 10 million tones of shells are produced from the bivalve mollusk family. Oyster shells make up 33% of that waste and are typically dumped in a landfill. Our OYSTERLEAN™ technology taps into the incredible potential of this waste to create a bio-based carbon source for plastic production.
OYSTERLEAN™ Is a marine waste-derived calcium carbonate (CaCO3) substitute that works with the majority of polymers. Once the oyster shells are collected, they are sent through a heat process that removes allergens. This neutralizes the additive of shellfish allergens so anyone can use a product enabled with OYSTERLEAN™.
After the allergens are removed, the oyster shells go through a sophisticated milling process to ensure a 1 to 2-3 micron particle size. Our facility has the ability to create 40,000 tons of OYSTERLEAN™ annually!
Once milled, OYSTERLEAN™ can be included in the production up to 50%.
Calcium carbonate is found around the world in many forms including, chalk, limestone and shellfish. It is a versatile material and can be used to create paper, plastics, paints and coatings. It can also be found in household and food items, and is a truly important material in the construction industry. Shellfish create carbon carbonate shells from filtering carbon and calcium from the water.
OYSTERLEAN™ reduces the environmental impact of conventional plastic with bio-based carbon sourced from oyster shells. This technology improves the mechanical characteristics of plastic, and reduces processing times, temperatures, and the dependence on fossil fuel-based resins.
In comparison to other bio-based resins, OYSTERLEAN™ is easier and seamless to integrate into production and actually supercharges production time!
A Life Cycle Assessment (LCA) completed on OYSTERLEAN™ found OYSTERLEAN™ has nearly 5x less climate impact than PE and PP.
LCAs measure the environmental impact of a product throughout its entire lifecycle, from cradle to grave. LCAs look at the following things to uncover the full impact of a product in the environment:
The environmental impact of a product is not just about its end-of-life disposal (such as recycling, landfill, marine, etc.), but rather a combination of all of the above.
OYSTERLEAN™ improves material flow and machine throughput and reduces the amount of energy used in the manufacturing process.
Yes! One of the main benefits to using OYSTERLEAN™ is the fact that the shells permanently take carbon out of the ocean when they are growing. According to studies, 8.36388 grams of carbon can be sequestered per 2-year lifecycle of an oyster.
OYSTERLEAN™ works with a all polymers and is best used as a whitening agent to replace limestone and titanium dioxide. This bio-based substitute is not a filler and can be included in production up to 50%.
OYSTERLEAN™ is white in nature so it works well to replace whitening agents like chalk, talc, limestone and titanium dioxide.
