At Novsus, we work every day with a clear purpose: to offer sustainable alternatives to traditional plastic. One of the key pillars of this transformation is biofillers, also known as natural fillers.

In this article, we explain what a biofiller is, how we use it at Novsus, and why it’s making a significant breakthrough in the development of eco-friendly materials.

What is a biofiller?

A biofiller is a biologically sourced material that is incorporated into a plastic matrix to:
• Reduce the use of fossil-based polymers.
• Improve mechanical, thermal, or aesthetic properties.
• Significantly reduce the environmental impact of the final product.

Biofillers offer an innovative solution to move toward a circular, efficient, and clean economy.

Oryzite: the biofiller transforming sustainability

At Novsus, we use Oryzite, a unique biofiller made from rice husk—an abundant agricultural by-product not suitable for human or animal consumption.

We transform it through a proprietary, clean process with no chemicals or water, endowing it with thermoplastic properties ideal for integration into technical compounds.

Why is Oryzite a game changer?

• It comes from an agricultural by-product: it doesn’t compete with the food industry.
• It requires a low-impact transformation process.
• It’s versatile: it can be combined with fossil-based or plant-based polymers.
• It meets the performance standards required by industry.

Oryzite not only reduces plastic use, but also drives a truly circular production model.

Tailor-made sustainable compounds for every client

At Novsus, we develop custom compounds based on the specific needs of each application, adjusting:
• The percentage of plant-based filler.
• The required technical properties.
• Each client’s aesthetic and sustainability goals.

Thanks to Oryzite’s flexibility, we work with multiple sectors seeking real alternatives to plastic, without compromising quality or efficiency in their manufacturing processes.

A fast-growing alternative to plastic

More and more brands and manufacturers are turning to sustainable compounds with Oryzite, drawn by its:
• Low environmental impact.
• Competitive technical performance.
• Alignment with modern consumer values.

This trend responds to a growing awareness: the need to design products that care for the planet without sacrificing functionality.

The ricevolution has begun

The ricevolution is not a passing trend: it’s a new way of understanding materials and their role in our relationship with the planet. It means rethinking how we design, manufacture, and consume, with values like sustainability, resource efficiency, and environmental responsibility at the core.

At Novsus, we firmly believe that the materials of the future must be born from respect for the present. That’s why we develop circular, clean, and zero-waste solutions—like compounds with Oryzite—that move the industry forward without compromising performance or technical feasibility.

Our mission goes beyond creating a new material: we aim to drive a paradigm shift. A change in how brands conceive their products, how consumers choose, and how all of us—companies, designers, and engineers—commit to a more sustainable future.

We invite you to be part of this transformation.
It’s not just about changing a component.
It’s about changing the impact of an entire industry.
