Microplastic-free Encapsulation for Regulatory and Sustainability Alignment

With EU restrictions on microplastics and growing scrutiny of persistent polymers, formulators must reassess encapsulation strategies. Transitioning toward microplastic-free formulations is becoming essential to secure regulatory compliance and strengthen sustainability positioning.

Calyxia NaturaCaps™ supports this shift with biodegradable microencapsulation technology designed to combine regulatory compliance, environmental responsibility, and formulation performance.

The Microplastics Challenge in Agricultural Formulations

Although effective in delivering active ingredient performance, these materials are now classified as microplastics under current EU definitions. Substitution pressure is increasing, driven by evolving regulation and environmental concerns.

The Regulatory Landscape

In 2023, the European Union adopted Commission Regulation (EU) 2023/2055, amending REACH to restrict intentionally added microplastics. The restriction applies to solid synthetic polymer microparticles meeting size and persistence criteria, while defining exclusion categories such as biodegradability meeting specified standards.

Transitional timelines are in place, with progressive deadlines extending to 2031 for plant protection products, due to long product development and registration cycles. Early reformulation planning reduces compliance risk and helps secure continued access to European market.

This type of restriction is likely to influence, and potentially be mirrored by, regulatory initiatives in other regions over the coming years.

Environmental Persistence and Ecosystem Impact

Beyond regulation, the environmental persistence of polymeric materials is increasingly scrutinized by regulators, customers, and investors. Accumulation in environmental compartments may have impacts on soil health, ecosystem functions and biodiversity.

Sustainability expectations are rising across the agriculture value chain and inputs are now expecting to demonstrate not only performance but also responsible environmental behavior over their life-cycle, aligning with sustainable agriculture objectives.

Implications for Capsule Suspension Formulations

Capsule suspensions relying on microplastics may face reformulation pressure due to:

• Burden of increased regulatory documentation
• Competitive disadvantage
• ESG exposure

Microplastic substitution therefore becomes both a compliance necessity and a strategic differentiator.

Calyxia has developed Calyxia NaturaCaps™, a platform of biodegradable microcapsules engineered for agricultural applications.

Calyxia NaturaCaps™ are engineered to deliver performance while enabling degradation under defined environmental conditions. This approach enables microplastic substitution without compromising formulation performance.
