Caleyda: food‑grade approval process begins

Key highlights
  • EFRO-funded plesTic Ready supports the start of a food-grade approval process for Caleyda®.
  • The project targets mixed-culture PHA production from organic residual streams, a sustainable and cost-effective feedstock.
  • The initial phase will explore certification challenges and technical and procedural solutions for mixed-culture materials.
  • Consortium partners include H&P Moulding, Happy Cups, NHL Stenden, WUR and SUSPACC under a Northern Netherlands grant from plesTic Ready.

Start and funding

With support from the EFRO-funded project plesTic Ready, the food-grade approval process for Caleyda® has begun. The initiative aims to scale the technology and bring biopolymers derived from organic side streams to market.

Mixed-culture production challenge

The project focuses on mixed-culture production, which increases complexity for food-grade certification. Materials produced from organic residual streams are targeted because they offer a sustainable and cost-effective feedstock for PHA.

Consortium and objectives

The approval effort begins with an exploration phase to identify certification challenges and solutions, involving value-chain collaborators H&P Moulding, Happy Cups, NHL Stenden, WUR and SUSPACC. The consortium's grant was approved as part of the plesTic Ready initiative in Northern Netherlands, which brings together companies, knowledge institutes and governments to remove barriers to circular plastics innovation by addressing technology, policy, logistics, economy, social acceptance, innovative design and corporate/community factors.
