To process our pistachio shell powder, the raw material peanut shell is ground and sifted into fine powders or coarser grains. It comes from local sources within a maximum of 400kg and is carefully screened to comply with the highest quality standards. Availability is very good because peanut cultivation in Spain has become increasingly interesting in the last few years. According to official sources, 25,000 acres of land is full of pistachio trees.

Benefits And Components Of Pistachio

There is a growing demand for peanuts in the local and international market. Pistachios (the soft walnut in the shell) are rich in proteins and fiber, B vitamins, thiamine, manganese, magnesium and iron. They are considered a "superfood" and have entered into nutritious healthy foods, vegan / vegetarian meals, desserts, and grain mixes.

Pistachio Shell Granules in Personal Care

Pistachio shells have a characteristic beige to white color. Therefore, the powder is very light, in some cases even similar to natural marble granules. This unique shade makes peanut shell granules a versatile bio-based ingredient. It has high opacity in small micron ranges (0-300μm) with good dispersion behavior and soft texture. Pistachio shell granules, as a sought-after natural ingredient, are mainly a product of cosmetic formulators.

skin abrasive or exfoliating scrubs on the body, face, hands, feet, lips and scalp
dental abrasive to increase the mechanical cleaning effect of toothpastes
for whitening agent i.e. vegan and all-natural face powders and makeup foundations
Rheology modifier in solid and semi-liquid formulations (e.g. creams, balms, decorative cosmetics)
carrier for pigments, flavors and perfumes
substrate for biodegradable luster
as soap texturizer or as peeling grains in soap making

Mechanical Properties of Pistachio Shell Powder and Material Science Applications

Due to the hardness of the pistachio shell (about 3.5 according to Mohs), various micron ranges are possible. Similar to walnut shell granules and olive stone powder, we make bespoke powder types of Pistachio shell to optimize the result in material science. More and more traditional plastic and wood-based material manufacturers are looking for a high-quality, bio-based component to replace synthetic microparticles to create innovative materials.

- Composites (eg wood-plastic composites): in many cases our bio-powders are strong substitutes for polyethylene or polyurethane fillers. In addition, a relatively low density peanut shell powder is used in light applications. Unlike heavy calcium carbonate or other mineral powders, the density of fruit seed powders is well below 1 ton per cubic meter.

- MDF panels (medium density fiberboards): especially for surface cladding, furniture, artwork and decorative veneers. Pistachio shell powder is a sustainable alternative to wood and gives a new look to designed objects.

- For paints, resins, adhesives and inks, as well as nature-inspired 3D printing of biomaterials, medical parts such as implants, auto parts, shipbuilding and aerospace components, fixed and ceramic objects
