Annual growth rate of carbon nanomaterials market
In laboratories around the world, scientists are pioneering a waste-to-wealth revolution that turns various forms of carbon waste into high-value nanomaterials with extraordinary properties. But beyond the economic potential lies something even more valuable: the opportunity to address two critical challenges simultaneously—waste management and sustainable material production.
Carbon nanomaterials are structures composed primarily of carbon atoms arranged in nanoscale dimensions (typically 1-100 nanometers). What makes these materials extraordinary is their combination of exceptional properties: high surface area, remarkable mechanical strength, excellent electrical and thermal conductivity, and often intriguing optical characteristics 3 8 .

A groundbreaking study demonstrated for the first time that waste PET plastic bottles could be converted into activated carbon nanoparticles (ACNPs) for use as high-performance lubricant additives 9 .
PET plastic bottles were washed, dried, and shredded into small pieces.
Shredded plastic was heated at 500°C for one hour in an oxygen-free environment.
Resulting activated carbon was collected and milled to achieve nanoparticles.
SEM, TEM, XRD, and BET analysis were used to examine properties.
ACNPs were added to lithium grease in five different concentrations.
Four-ball wear test and load-carrying capacity test evaluated performance.
