A bio-renewable and sustainable resin

Bio renewable oyster shells

Oysterlean is a game-changing product derived by refining a readily available bio-marine waste material sourced from seashells that results in a bio-renewable resin capable of replacing oil-based plastics.

The market today faces one crucial question, how to reduce the environmental impact on plastics packaging and be more sustainable in the aspect of rising raw material cost?

Three prime areas of the packaging lifecycle demand our focus. All of them will have positive improvements to the sustainability of the packaging. Reuse, How can we extend the lifetime of a plastic packaging product? Recycle, how can we recover this valuable material? Lastly, Renew, how can we use less of the traditional non-renewable raw material?

Existing technologies are either far too expensive, incompatible with the general disposal waste stream for recovery of plastics or do not functionally perform from a technical or even environmental perspective.

What is Oysterlean

Oysterlean is an end-product resulting from the refinement of a bio-marine waste material sourced from seashells. The shells are collected, refined and processed into pellets which are made adaptable and viable to be used by the plastics packaging industry. The potential of a bio-renewable resin capable of replacing oil-based plastics.

Refining this non-food bio-marine waste material as a bio-renewable substitute not only reduces the need for fossil fuel-based resins, Oysterlean provides improved sustainability performance to plastics packaging in three areas of our sustainability mission. Environment application, cost stability and production compatibility.

Environmental Benefits

Oysterlean’s carbon footprint is about five times lower than conventional plastics like PE and PP. Thanks to more than 75% of Oysterlean being based on bio-marine waste (shells) and carbon capture (storage) in shells. Assumptions based on an LCA (ISO 14040) provided by SGS.

Since more than 75% of Oysterlean is a bio-marine waste from shell farming, the bio-regeneration cycle of this material is 4-6 months until it becomes a waste.

Incineration of Oysterlean has little environmental impact, and only 23.5% of the CO2 is not environmentally neutral and/or is going back into the bio-circulation.

Carbon Footprint Impact in CO2 kg equivalent

Oysterlean -0.9 kg
Polypropylene -4.39 kg
Polyethylene -4.85 kg
Polystyrene -7.85 kg


Oysterlean is compatible with virtually all plastics and production processes, including many resin materials. It provides high durability, both as raw material and also in the final product.

Cost Stability

Oysterlean offers a stable price far longer than many other suppliers of materials used in plastics packaging. Since it is not dependent on petroleum-based nonrenewable raw materials and has a stable supply of renewable bio-marine raw materials, Oysterlean is a buffer to the volatile resin prices.
