Abstract:The main goal of this study was to produce and extensively examine biochar as a potential material for the in-situ adsorption of typical pollutants carried by the stormwater runoff from the transportation infrastructures. Biochar, a product of controlled pyrolysis of carbon-rich waste material is the best known for its adsorption capacity as used for agricultural applications. The individual source of organic waste material, and parameters of pyrolysis, such as duration, temperature, limitation of oxygen, etc., would influence its final properties, which will dictate the overall efficiency of in situ adsorption. The choice of waste biomass transformed into biochar is very important when final product is to be applied on commercial scale. There are several conditions that must be taken under consideration. For instance, the organic waste should be easily available for manufacturing, and be stable after pyrolysis. Mississippi is a State with heavy agriculture and farming; it is also “green” state with extensive forest and green foliage. The carbon-rich waste material used for this study represents organic waste produced by those activities: fragments of trees (bark nuggets, pine needles, and cypress mulch), waste from agriculture (corn stover) and animal waste (manure). Long-term goal of this research was to investigate with further optimization a green technology approach for the effective, low-cost and environmentally friendly clean-up of contaminants spilled on the roads. To develop the foundation for reliable technology, the crucial parameters needed for production of biochar with designated properties had to be investigated first.
