Biocomposites granules

Granules with textile and agro-food waste
Circularity and Innovation

The biocomposite acetate granules offered by Mazzucchelli are the result of true circular innovation: starting from cellulose acetate, we enrich it with natural or recycled materials, such as agro-food and textile waste. The result? Sustainable, high-performance materials that give new life to what would otherwise be discarded, telling a genuine story of sustainability.

 

Reuse of textile and agro-food waste

By using waste that would otherwise be sent to landfill, Mazzucchelli reduces the environmental impact of the industrial supply chains involved. Typically, up to 20% of residual materials can be incorporated into our formulations.

The additives are sourced from processing centers as close as possible to our facilities to minimize transportation impacts.

Our granules incorporate:

  • Waste from denim, cotton, and viscose fabric production 
  • Residues from various wood processing operations 
  • Waste from agro-food processing, including rice and tobacco 
  • Recovered spent coffee grounds 
  • Other plant-based components 

Mazzucchelli’s careful approach to compounding significantly reduces the material’s carbon footprint.

Measurable sustainability performance

We can use as the base component either the standard cellulose acetate formulation, the M49 or M49 TEC versions to achieve different sustainability percentages depending on design requirements. As with all other Mazzucchelli granules, biocomposites can also be recycled after use, either through conventional recycling or molecular recycling (CRT).

No limits to processing

Mazzucchelli biocomposite granules are designed to perfectly adapt to the most common processing technologies, such as injection molding and extrusion, offering maximum production versatility.

To make the product even more sustainable, we recommend using biocomposite granules in their natural color, derived from the incorporated recycled material, avoiding the addition of extra pigments and dyes. However, if desired, it is possible to modify the color within the limits of the added components.

Applications of biocomposite granules

Mazzucchelli biocomposite granules are the result of a research and innovation journey aimed at extending the use of cellulose acetate well beyond the traditional boundaries of eyewear, offering an extremely flexible material suitable for various sectors such as cosmetic packaging, fashion jewelry, and numerous other applications where sustainability and aesthetic quality are key elements.

Mazzucchelli’s ability to tailor the properties of biocomposite granules to different design requirements allows for customized solutions that combine technical performance, strength, transparency and a natural tactile feel in a single material. Born from continuous research and development, Mazzucchelli biocomposites embody a circular approach and the reduction of fossil raw material use.

Thanks to the company’s expertise in processing acetate, Mazzucchelli is now able to provide sustainable materials that offer a concrete alternative to traditional plastics and support the evolution of multiple industrial sectors toward a more responsible and innovative future.

Other Mazzucchelli acetate granules

In addition to Biocomposites granules, Mazzucchelli’s offering includes:

Standard cellulose acetate granules:

Standard cellulose acetate granules with DEP plasticizer from fossil sources represent the traditional product that has been used for decades in the eyewear, tooling and fashion accessory industries. Easily processed through injection molding and extrusion, they have a sustainability content ranging from 41% to 65%. →
Standard cellulose

M49 granules based on cellulose acetate and a bio-based plasticizer:

M49 is Mazzucchelli’s patented formulation that retains all the physical–mechanical properties as well as the transparency and colorability of cellulose acetate, while using a renewable-source plasticizer. This increases the material’s sustainability content to between 67% and 95% and makes the product biodegradable. →
M49 granules

M49TEC granules based on cellulose acetate and a food-approved bio-plasticizer:

A further evolution of the M49 formulation, developed in our laboratories, uses a renewable-source bio-plasticizer approved for food contact under specific conditions of use, making Mazzucchelli granules the ideal solution for the cosmetic packaging sector. →
M49TEC granules

FAQ

  • What are Mazzucchelli biocomposites?
    +
    Biocomposites are cellulose acetate–based granules to which we can add plant-based fillers from various recovery and recycling sources, such as residues from agro-food or textile processing.
  • Which types of cellulose acetate are used for biocomposites?
    +
    All grades of cellulose acetate can be used, from the standard formula to M49 and M49TEC. The plasticization percentages can also be adjusted according to the physical properties required for the specific application.
