Grinding and micronizing
NaturePlast is equipped with various grinding technologies to find the most suitable solution for each by-product to be processed:
- crumbling-crushing,
- blade grinding,
- attrition grinding with paddle or pin plates.
This equipment enables us to work upstream on relatively large products of several tens of centimeters in size, with a view to reducing them to particles of a few mm, hundreds or tens of microns.
Laboratory equipment enables us to achieve throughputs of a few hundred grams to a few kg per hour.
Industrial equipment can achieve throughputs of several tens of hundreds of kg/hour, depending on the by-product to be processed and the particle size required.
Full stainless steel micronization equipment enables us to work on markets requiring specific certifications.
Weighing – packaging
Once the products have been processed, they are weighed and then packaged in the format required by the customer, in jars, sachets, bags or big bags, then placed on cardboard or pallets.
Screening
We are equipped with sieving equipment from laboratory to industrial scale, enabling us to sieve a variety of products with the multi-cut particle size separations required by the customer after the grinding-micronization stage.
Quality control
Our laboratory constantly performs the analyses required to ensure compliance with specifications and consistent quality of the finished product:
- weight control from receipt to packaging
- grinding temperature control
- granulometric control on laboratory sieves
- hygrometric control by Karl Fisher analysis
We can subcontract other types of analysis (laser or other) according to our customers’ needs.

Type of by-products
Most of the by-products come from France. The processes selected were chosen for their industrial viability, in terms of volumes and quality (batch reproducibility), and their technical and environmental relevance.
The list of available by-products is not exhaustive, and new by-products can be identified and validated according to a specific need.
It is therefore entirely possible to work on new by-products with a view to a circular economy project, the aim of which would be to achieve coherence between the activity generating the by-product and its reuse.
Business sectors and applications
Our services cover a wide range of sectors and applications:
- Agri-food: shellfish, seaweed, cockles, pits, seeds, dehydrated pulp, dehydrated marc, etc.
- Plants / plant fibers: wood, flax, hemp, flowers, etc.
- Textiles: leather, cotton, etc.
- Chemicals and minerals industry
- Plastics processing: plastics and elastomers
- Recycling: orientation and feasibility tests for plastics recycling
