Recycling of plastics

There are several processes for transforming plastic waste into raw materials: mechanical, chemical and biological recycling, thermolysis or thermal decomposition/dissociation (using heat).

Materia Nova offers its expertise to:

• Identify the nature and quantity of the different materials that make up batches of waste obtained by mechanical recycling, characterise them in order to establish relationships between the composition and properties of the batches and reformulate them in order to optimise their properties and adapt them to customer specifications.
• Improve the properties of recycled plastics (PLA, PO, PU,...) in order to give them superior mechanical properties (mechanical resistance and impact and traction, fluidity, ... ),
• Improve the mechanical recycling of plastics by proposing protocols (grinding of the material to be recycled, drying of the material before extrusion, extrusion, evaluation of the MFI, etc.) in order to preserve the properties of the products after their passage through the extruder,
• Transformation of waste into filament for additive manufacturing thanks to its prototyping line accompanied by the necessary peripherals (dryers, grinders) which enables the development of prototype formulations specific to the specifications of customers and their applications.

Modifying the chemical structure of plastic waste by converting it into shorter molecules ready to be used for new chemical reactions.
