At the time of this study, commercialization had progressed to the construction of a pilot plant for latex extraction and the planting of over 2000 ha. Currently, a larger four story pilot plant is in operation. Wastewater following latex extraction is discharged into evaporation ponds. As commercialization reaches full scale, the liquid waste stream from latex extraction will become an increasing disposal problem. Four potential problems were identified with the disposal method used in the study pilot plant: (1) an unpleasant odor due to the high ammonia concentration of the waste liquid, (2) negative effects on soil properties due to the high Na concentration in the ammoniated antioxidant solution (AAO) used in the extraction process, (3) potential loss of latex in the waste liquid, and (4) potential treatment and disposal costs of the waste water to meet regulatory guidelines. Ammonia is also used in the current pilot plant but not in the extraction medium itself. In addition, either the potential negative effects on soil properties and/or the presence of latex in the wastewater could slow the evaporation process and infiltration of water into the soil. The very slow infiltration of water into the soil profile has been observed in the current evaporation ponds. The objectives of this study were to (1) evaluate the properties of the liquid waste streams after latex extraction, (2) determine if the waste liquid could be reused, and (3) determine if any of the waste liquid could be recycled for latex extraction.
