Extraction

Definition

Extraction is the process of obtaining valuable materials or substances from natural resources, often involving the separation of specific components from a larger matrix. This process is crucial in the production of biobased materials, as it allows for the utilization of renewable resources such as plants, biomass, and agricultural by-products, ensuring sustainable sourcing and reducing reliance on fossil fuels.
