BioPowder.com is a specialist for innovative fiber additives and functional composite fillers originating from the circular economy. We transform olive oil by-products into powders of high quality and with unique characteristics such as excellent stability, homogeneous particle shape and a bright color.
These properties make them highly suitable as natural fillers and reinforcing fibers for composite materials. Composites are materials made of two components that have distinct physical and chemical properties. In combination, the two components ensure enhanced characteristics of the finished compound.
In recent times, there has been a strong trend of making natural composites, i.e. nature-inspired materials with a reduced carbon footprint and better recyclability. Most manufacturers take the approach of replacing synthetic components, e.g. glass or plastics, with natural and renewable materials - above all natural fillers and fiber additives. The result are bio-composites (also called natural composites), i.e. new materials with a certain percentage of natural and/or plant-based ingredients.
In recent years, a variety of plant-derived fibre additives have been used in composite manufacturing: wood fibers, starch, flax, hemp, corn cob, bagasse and coconut fibre – just to name a few. Depending on the final application, these materials have their advantages and shortcomings. In addition to not always producing satisfactory mechanical properties, many natural fillers are not necessarily sustainable, in spite of their herbal origin.
At BioPowder.com numerous circular raw materials, i.e. agricultural side-streams, have been tested. In a comparative fashion, sustainability criteria and mechanical performance parameters were analyzed. The bottom line: refined, pulverized olive pits, i.e. olive oil production by-products, demonstrated the best performance, i.e. excellent results due to their physical and chemical particle structure. As a consequence, our fully bio-based and biodegradable line of functional composite fillers was born. Marketed under the brand name Olea FP (Functional Powder), BioPowder.com fiber additives are an optimized solution made from sustainable raw materials. Compared to other plant fibres, these natural fillers and reinforcing fibers offer the following advantages:
BioPowder.com composite fillers offer a number of benefits when used in composites for the following applications:
Our Olea FP product line of micro-powders can add significant value to rubber compounds for tyres, seals and hoses, shoe soles and similar items. Strength and stability can be improved when adding our fiber additives in varying doses. Besides, the environmental impact of microplastics, generated through the abrasion of rubber items (tyres, soles, etc.), can be significantly reduced when natural composite additives are added. BioPowder.com fibre reinforcement solutions are available in both natural and treated variants. The latter includes coated particles, such as silanized composite fillers, to maximize compatibility with different rubber compounds such as TPU, TPE, EVA and others.
BioPowder.com natural fillers and reinforcing fibers can add strength, stability and abrasion resistance to PVC-based composite systems. Besides, they can enhance the development of ecological linoleum products with superior performance. Similar effects are possible when integrating our micronized composite fillers into molded PVC components for diverse technical applications.
To facilitate your development works, we have recently started to create our own bio-based composite mixes. With the goal of improving existing PVC systems, we launched an ultra-resistant floor coating with hydrophobic properties. Our naturazzO resilient flooring solution contains up to 40% of Olea FP composite fillers and has proven effective for high-load industrial surfaces.
BioPowder.com composite additives were designed to enhance construction materials made from engineered wood and reinforced plastic. Especially bio-plastics used in a wide range of end products can be enhanced with Olea FP fibre reinforcement solutions and natural fillers. Besides, performance and environmental sustainability can reach new levels when they are integrated in 3D printing filaments and textile fibers.
Reinforcing Fibers for Sealants and Adhesives
Most sealants and adhesives are polymer formulations applied to bond two different substrates. Traditionally, they have been made from non-recyclable silicones or polyurethane. BioPowder.com natural fillers have been developed to boost the bio-based content of existing sealant formulations while enhancing mechanical properties such as abrasion resistance and strength. Our additives for bio-based composites are suitable for one- and two component systems and available as natural or hydrophobic grades.
Especially the packaging industry has strongly relied on our functional powders and fibre reinforcement solutions to create a new generation of environmentally friendly plastics. Degradability is also a desired property in many state-of-the-art consumer items and design objects. Nearly any polymer - from agricultural films to packaging foils up to funeral urns - can be upgraded with BioPowder.com fiber additives to accelerate degradability / compostability and to add reinforcing elements.

Composites can come in a variety of compositions. The term “composite” essentially describes a material that is made up of two or more different components, essentially to enhance its technical and mechanical properties. Most commonly, a composite consists of a binder/resin and a composite filler. The latter is often added for fibre reinforcement and mostly consists of a biodegradable material. Also the underlying resin can be of bio-based origin and degradable to varying degrees, i.e. mostly industrially (as opposed to home-compostable).
Apart from the resin or binder, composites commonly contain fiber additives / reinforcing fibers and natural fillers besides coupling agents and other compatibilizers. Depending on the final application of the compound, those composite additives help create a certain texture, aesthetics as well as mechanical properties that meet the user's specifications. Especially in high-tech applications (e.g. automotive, medical, aerospace, etc.), a certain level of stability and abrasion resistance are mandatory requirements that are best ensured by using powerful composite fillers. At BioPowder.com, we can provide fully plant-based and compostable alternatives to synthetic composite fillers such as carbon fiber, glass or quartz.
Bio composites can be either bio-based, bio-degradable or compostable. In some cases, all three characteristics are met, in others a bio composite is only industrially recyclable. In general terms, it can be said that bio composites contain a significant percentage of composite fillers / composite additives / reinforcing fibres of natural origin. This is what BioPowder.com has specialized in: fiber additives from purely plant-based resources, all from circular side streams and made in a waste-reducing manufacturing process. They are suitable for most composites in which strength, stability and abrasion resistance are desired properties. Thanks to the hardness and low density of our compostable composite fillers, numerous lightweight composites can be improved - also in terms of their ecological footprint. Especially bio-composite materials for extrusion and injection - usually made with modern compounding technologies - can be successfully enhanced with BioPowder.com fibre reinforcement solutions.
Traditionally, compounding resins (for example polyethylene, polypropylene or polyurethane) have been reinforced with glass or carbon fibre. More recently, a number of bio-based resins such as PLA, PHA or other plant-based polymers have been used and reinforced with natural composite additives like plant-based reinforcing fibres. Essentially, manufacturers have followed the trend of replacing resins of fossil origin with plant-based polymer solutions. There is also a growing demand for compostable composite materials made from starch or cellulose and reinforced with natural fillers.
Some composite materials are developed especially for 3D-printing applications. The most prominent examples are filaments made from PLA (polylactic acid) or ABS (acrylonitrile butadiene styrene). Numerous application trials have demonstrated high potential for improvement of those 3D printing composites with lignocellulosic composite fillers. In response, BioPowder.com has developed powdery natural fillers made from upcycled olive stones. They integrate smoothly with the 3D printing filament matrix and add stability, texture and abrasion resistance to the resulting natural composites.
Composite materials can be classified by different aspects, above all based on their composition and/or underlying base material. To go by the traditionally used 4 categories, there are polymer matrix composites (PMCs), metal matrix composites (MMCs), ceramic matrix composites (CMCs) and wood composites. Due to the numerous recent developments, especially in the field of bio-based composites with fiber additives, those categories can be expanded. Countless materials can be part of more than one category; not to mention the field of cementitious natural composites such as reinforced concrete. Moreover, many composite additives are nowadays of natural origin and very multifunctional.
As a specialist manufacturer, we cater to industrial customers, preferably with a strong focus on research and development in the field of natural composites. Our goal is to partner with innovative B2B players wishing to make a difference in terms of technical and environmental performance. Therefore, we provide our fibre reinforcement solutions in small, medium and large batches. We work globally and offer integrated logistics solutions to ship our composite additives worldwide.
