In a circular bioeconomy, maximizing the use of ligno-cellulosic-biomass waste is paramount for the full utilization of energy, products, and chemical commodities with minimal environmental harm. One beneficial and low-cost value-added product that can be produced from agricultural waste is activated carbon (AC). AC has several uses, especially as an adsorbent for wastewater treatment. Wastewater treatment plants utilize AC to remove pollutants. The AC properties can often be tailored by changing the reaction parameters for the preparation of biochar precursors and activation methods. AC can be made from biochar precursors using either physical or chemical activation. Currently there is a need for improved methods for preparing activated carbon – methods that are less expensive, produce less waste and provide better control of the properties of the carbon product.
Researchers led by Prof. Abdul-Aziz at UCR, have developed a patent pending, process for the thermal conversion of agricultural waste to activated carbon. The conversion process parameters can be varied to modify the properties of the activated carbon.
- Tailorable (More control on properties of formed activated carbon)
- Cheaper method for formation of activated carbon (at least 10% cheaper)
- More environmentally conscious (use of agricultural waste)
Conversion of agricultural waste into customizable activated carbon for the removal of contaminants in water and wastewater applications.
