| A disposal system for pesticide waste was examined for the ability to isolate waste pesticides onto lignocellulosic matrices, such as peat moss (PM) or steam-exploded wood fibers (SEW) by sorption processes, and to detoxify the pesticide during solid state fermentation (SSF) in contained bioreactors.;Emulsions formed from typical pesticide formulations act as a barrier for pesticide sorption. Adding Ca(OH);Atrazine and chlorpyrifos dissipation in field SSF bioreactors increased with higher bioreactor temperatures (65;Supplemental energy and fertilizer sources (corn meal, vegetable oil, and chicken manure) enhanced microbial activity and pesticide degradation in field bioreactors. The dissipation of atrazine was not enhanced by nutrient amendment in laboratory studies involving ;It is important to keep pesticide waste bioreactors well aerated, moist, and mixed with additions of nitrogen and fresh biomass to facilitate the dissipation and detoxification of pesticides. The remaining residue can be land applied, land filled, or incinerated. |
