Biodegradable PLA-based Thermoplastic Compound: Sustainability and Performance for Eco-Friendly Products

Towards a New Generation of Sustainable Materials

The growing focus on sustainability and reducing environmental impact is driving research towards biodegradable polymeric materials capable of replacing traditional fossil-based plastics.
Among the most promising solutions is the PLA-based biodegradable thermoplastic compound (polylactic acid), a material derived from renewable resources such as corn starch, sugar cane, or sugar beet.

This type of ecological compound for injection molding combines the aesthetic and functional properties of conventional plastics with a sustainable life cycle, while ensuring strength, stability, and controlled recyclability.

The “Green” Collaboration between Prodir and LATI

An exemplary case of practical application of biodegradable PLA compounds is represented by the collaboration between Prodir, a Swiss company leading in promotional writing instruments production, and LATI, manufacturer of high-performance thermoplastic materials.

Prodir chose a specific formulation from the LATIGEA range, a wood fiber reinforced PLA-based thermoplastic compound, to create a new line of sustainable pens.
The goal was to create a product that is:

• aesthetically refined;
• mechanically robust;
• biodegradable and compostable;
• manufactured without the use of petrochemical polymer alloys or oxo-degradable additives.

This collaboration has resulted in a durable promotional item consistent with the principles of eco-design and environmental responsibility.

PLA and Biocomposites: Characteristics and Performance

PLA-based biodegradable thermoplastic compounds can be modified with natural fibers, organic additives, and vegetable pigments, achieving a wide range of mechanical and visual properties.
LATI, for example, has developed formulations with different types of reinforcements, maintaining the material’s complete plant-based origin.

Thanks to its bio-composite structure, the material is easy to process through injection molding, maintaining high aesthetic quality and a pleasant tactile sensation.
Additionally, the addition of natural pigments allows for customized coloring without using synthetic or polluting substances.

Sustainability and Production Cycle Integrity

The development approach of the biodegradable PLA compound fully respects the principles of circular economy.
Unlike oxo-degradable materials or PLA-petrochemical blends, these compounds:

• do not release microplastics during degradation;
• maintain controlled biodegradation in an industrial environment;
• do not compromise production chain recyclability.

Furthermore, the production cycle is characterized by a reduced CO₂ impact, both in raw material sourcing and processing, making the material suitable for sustainability-conscious sectors such as:

• ecological packaging,
• industrial design,
• promotional items,
• components for furniture and lightweight devices.

Biocomposites and Durability: a Winning Combination

One of the strengths of wood fiber PLA compounds is the product durability, which far exceeds that of traditional biopolymers.
The combination of PLA and natural reinforcements provides:

• structural rigidity;
• moderate impact resistance;
• dimensional stability over time;
• excellent aesthetic performance even after long periods of use.

These properties make PLA compounds ideal not only for biodegradable single-use products but also for long-life products, such as writing instruments, design accessories, or furniture components.

Conclusion and Invitation for further Information

PLA-based biodegradable thermoplastic compounds represent a strategic choice for companies wanting to combine environmental sustainability with technical performance.
Thanks to the possibility of integrating natural fibers and ecological pigments, they offer design versatility and reduced environmental impact, meeting the needs of an increasingly green economy-focused market.
