Step-by-Step Process: From Olive Oil Waste to Packaging Material
Turning olive oil waste into packaging materials involves a series of established methods in waste management and manufacturing. Materials like Oliplast are molded into useful packaging products. Here's how the process unfolds, step by step.
Collection and Preparation of Olive Oil Waste
Everything starts with collecting two key byproducts from olive oil production: olive pits and olive pomace. Olive pits are separated during oil extraction, while pomace - the leftover pulp after pressing - contains cellulose fibers, which are essential for making packaging materials.
Once gathered, the olive pits are ground into fine particles to ensure they blend seamlessly with polymers. Meanwhile, the pomace undergoes mechanical treatments to extract cellulose fibers, separating them from other organic components. This step ensures the fibers are clean and at the right moisture level, with contaminants removed. These prepared materials are then refined into raw components, ready for the next stage.
Transformation into Raw Materials
The extracted cellulose from olive pomace is combined with natural biopolymers, such as starch or chitosan, to create films. For sturdier packaging, the ground olive pits are mixed with polymer bases, forming biocomposites. These olive particles act as natural fillers, improving the material's biodegradability. To enhance flexibility, plasticizers like glycerol are added.
Interestingly, olive waste also contains natural phenolic compounds, which provide antimicrobial and antioxidant properties. These features are particularly useful for food packaging, as they help inhibit microbial growth and prevent oxidation, keeping food fresh for longer.
Manufacturing the Final Packaging Product
In the final step, the raw materials are shaped into packaging products using standard plastic processing methods. Compounds like Oliplast are compatible with common manufacturing techniques, such as extrusion and injection molding.
For flexible packaging films, the cellulose-biopolymer blend is processed into thin sheets with enhanced tensile strength, flexibility, and water resistance. These films are ideal for direct food contact. On the other hand, sturdier products - such as trays, plates, and container caps - are made from the biocomposite materials. The entire process adheres to food safety standards while offering antimicrobial and antioxidant protection, which helps extend the shelf life of packaged goods.
