STARBON
Starbon® technology
Starbon (starch and carbon) is a novel carbonaceous material with tunable functionality derived from starch-rich waste. It was demonstrated and then published that the functionality of Starbon (especially concentration and nature of oxygen-containing functional groups) plays a crucial role in their applications in the field of heterogeneous catalysis, chromatography and adsorption.
Based on Dr. Budarin’s research in the area of semi-scale production of Starbons, an agreement was made with Sigma-Aldrich to sell the products via their catalogue, which led to significant industrial interest, and as a consequence prompted the University of York to launch a spin-out company, Starbon Technology Ltd. Dr. Budarin is one of the major shareholders, scientific advisor and inventor. The initial success of the Starbon team business potential and innovation has led to a prestigious Rushlight award for use of Starbons in water purification.

Separation of Precious and Earth Metals
Starbon® has been used to adsorb precious metals (Au, Pt and Pd) from a complex mixture also containing similar concentrations of earth abundant metals (Ni,Cu and Zn).
The experiments were also carried out to simulate ‘more realistic’ situations where the non-precious elements were more concentrated than the precious metals.

CO2 Adsoprtion
Starbon® samples exposed to 5 bar CO2 for 30 minutes at RT, weighed, then exposed to vacuum at RT and weighed again to get the mass change.
