Virgin cork colour and porosity as predictors for secondary cork industrial quality

Transforming wastes into functional materials: natural cork-based physical structural components and polymers

“…9 Pores on cork surfaces, evaluated visually or through imaging techniques, are indicative of cork quality, with increased pore number often signaling decreased quality. 10 Species with cork bark can be categorized based on the disposition of cork layers, necessitating thorough understanding of raw material characteristics before utilization. 11 Advancing our understanding of cork's structural, cellular, and chemical characteristics is paramount for its effective utilization.…”
