The transition to a low-carbon economy requires more than ambition. It requires verification.

At Catalyxx, we are proud to announce that independent radiocarbon (C14) testing has confirmed that our product contains 100% Bio-based Carbon Content, as determined under ASTM D6866-24 Method B (AMS).

This outcome confirms that the carbon in our product is entirely derived from renewable sources.

Why Verification Matters in Sustainable Chemistry

In the chemical industry, the origin of carbon is becoming an increasingly relevant parameter. As regulatory frameworks evolve and value chains seek greater transparency, the ability to quantify renewable carbon content with recognized methodologies is essential.

Radiocarbon (C14) analysis provides a scientifically robust way to distinguish between renewable carbon — derived from recently living biomass — and fossil carbon, which has been isolated from the atmosphere for millennia. The method is widely accepted for determining bio-based carbon content in chemical products and materials.

Independent verification ensures that renewable claims are supported by measurable data obtained under standardized laboratory conditions..

The Science Behind the Certification

The certification is based on radiocarbon (C14) analysis performed in accordance with ASTM D6866-24 Method B (Accelerator Mass Spectrometry, AMS), the internationally recognized standard for determining bio-based carbon content in materials and chemical products.

Radiocarbon analysis relies on the natural presence of carbon-14 in atmospheric carbon dioxide. Living organisms continuously exchange carbon with the atmosphere, maintaining a characteristic level of C14. Once the organism dies, this exchange stops and the C14 content begins to decay over time. Fossil resources, which have been isolated from the atmosphere for millions of years, contain no detectable C14.

By measuring the “percent modern carbon” (pMC) in a sample and comparing it to a contemporary reference standard, the method determines the fraction of carbon derived from recent biomass versus fossil sources. An atmospheric correction factor is applied in accordance with the standard to calculate the final percentage of bio-based carbon content.

Because the method directly measures isotopic composition rather than relying on process inputs or mass balance assumptions, it provides a robust and objective determination of renewable carbon content in the analyzed material.

In this case, the analysis confirmed 100% bio-based carbon content (as a fraction of total organic carbon), indicating that the carbon present in the product originates entirely from renewable sources.

Identical Molecules. Only Better.

A central element of Catalyxx’s technology is that the resulting molecules are chemically equivalent to those traditionally produced from petrochemical feedstocks.

The catalytic process transforms bioethanol into the same molecular structures currently used across multiple industrial applications. This means that performance characteristics, reactivity, and compatibility with existing industrial infrastructure remain unchanged. Downstream users do not need to redesign formulations or modify equipment to incorporate the product.

What changes is not the molecule itself, but the origin of its carbon.

By replacing fossil-derived feedstocks with renewable carbon, the process enables a measurable reduction in fossil carbon dependency while maintaining full industrial functionality. In this sense, the technology supports defossilization without requiring structural changes in established value chains.

The independent certification of 100% bio-based carbon further confirms that the renewable origin of the product is reflected at the molecular level.

This is what we mean when we say:

Identical Chemicals… Only Better.

Chemicals for the 21st Century

The chemical industry is responsible for a significant share of global fossil carbon consumption. True transformation will only occur when renewable carbon replaces fossil carbon at scale.

Technological solutions that maintain molecular equivalence while replacing fossil carbon with renewable alternatives offer a practical pathway forward. By enabling compatibility with existing infrastructure and industrial standards, such approaches reduce the barriers typically associated with material substitution.
Independent certification of renewable carbon content provides an additional layer of transparency, supporting traceability and alignment with emerging regulatory and market expectations.

Within this context, Catalyxx’s technology contributes to the progressive defossilization of chemical value chains, demonstrating that renewable carbon integration can be both technically viable and industrially scalable.

This is our contribution to building a resilient, defossilized chemical industry.

This is Chemicals for the 21st Century.
