Introduction to PHA

Definition and Origin

PHA is a natural polyester produced by bacteria during the fermentation of sugars or lipids. It comprises more than 150 monomers with properties that vary according to how they are linked together. Its polymers can be thermoplastic or elastomeric, with melting temperatures ranging from 40°C to 180°C. In short, a flexible, long-lasting solution.

Industrial and Environmental Issues

The use of PHA meets the requirements of the circular economy and the reduction of plastic waste. Unlike PLA, PHA degrades naturally in marine and terrestrial environments without leaving any harmful residue. In other words, enriched soil for a conquered planet and its inhabitants. It also helps to combat microplastic pollution and recycle organic waste.

PHA B2B Standards, Regulations and Labels

European framework for Bioplastics

• The SUP (Single-Use Plastics) Directive requires all products containing PHAs to be marked in accordance with Regulation (EU) 2020/2151.
• The EU is also supporting R&D projects via Horizon Europe to optimise the production of PHA from CO₂.

Compost: Certifications and Labels

• Suppliers are turning to certifications such as OK Compost (industrial composting) and OK Home Compost (domestic compost).
• The DIN CERTCO and EN 13432 labels validate the biodegradability of their materials under controlled conditions.

Industrial Applications of PHA

They are diverse and varied. PHA products cover all industrial and even medical sectors. This sustainable revolution is enabling B2B players to replace plastic with a viable, sustainable alternative. Here’s an overview of the uses…

Sustainable Packaging

PHA food packaging is in high demand, particularly for fresh produce and beverages. They offer an alternative to disposable cups and plastic tableware. This biodegradable packaging preserves food and transforms into bio-waste, providing a practical and environmentally-friendly solution. They benefit both consumers and businesses looking to reduce their carbon footprint.

PHA: From Earth to Plate, or Almost…

Agriculture is adopting bioplastics such as PHA for agricultural solutions such as mulch film and netting. Biopolymers such as PHA improve the sustainability of agricultural practices by minimising plastic waste and improving soil quality. Two birds with one stone.

Medical and Biomedical Sector

PHA is also used in the healthcare sector. It is used to manufacture sutures, implants and tissue engineering supports thanks to its biocompatibility and controlled degradation capacity. Orthopaedic devices (screws, plates, etc.) and kinesthetic devices also benefit from its mechanical strength and safety.

PHA Toys: Meeting Consumer Expectations

Shoppers, and parents in particular, are becoming increasingly aware of environmental issues. And that’s only natural: we’re talking about their children’s future. So they are keen to choose products that are safe, durable and made from harmless materials. PHA toys naturally comply with health and environmental standards for young children and their parents.

Eco-Friendly Clothing Made from PHA Fibres

PHA fibrous textiles are used to make eco-responsible clothing. These garments are resistant, biodegradable and durable, and offer technical and environmental performance. By taking into account the circular economy and the advantages of biodegradable materials, fashion houses are choosing sustainable and ecological solutions.

B2B PHA Supplier Selection Criteria

• Characteristics and traceability: The origin of materials and the recurrence of physical properties are essential for demanding manufacturers who must assume their responsibilities (declarations, test results, honouring commitments).
• Suppliers will have to provide the required technical data sheets (a TDS, an MSDS) that are complete and backed up by all the necessary information (study and analysis reports, in particular on the mechanical, chemical and even dynamic specifications of the materials, etc.).
• Production capacity and lead times: The volumes required in B2B are often significant. The focus is on annual capacity, batch flexibility and delivery times (which may logically be as important in the choice of packaging solution as price alone).
• Competitive pricing: The cost of PHA remains (generally) higher than that of conventional plastic. B2B negotiations will necessarily focus not only on price, but also on total volume, order regularity and – possibly – R&D costs.
• Technical support and innovation: A supplier must be able to make technical proposals, such as testing prototypes (both in the laboratory and in the field), and support the development of its range.
