Prospective Application of Flue Gas Washing Liquid from the Wet Scrubber Unit at Masaro Plastic Refinery for Pesticides
Abstract
The plastic refinery represents an advanced technology designed to effectively manage residual waste. This innovative approach integrates the principles of incineration and pyrolysis to yield valuable products, including fuel and flue gas washing liquid obtained from a wet scrubber unit as wastewater. The flue gas washing liquid contains various compounds, such as ammonia, which did not meet the quality standards stipulated by the Ministry of Environment. Furthermore, it also encompasses phenolic compounds, nitrates, and nitrites. These chemical constituents impede the direct discharge into the environment due to their inherent toxicity towards aquatic organisms. However, within the agricultural domain, ammonia, phenol, nitrate, and nitrite are extensively employed as pivotal ingredients, serving as valuable sources of nitrogen in the production of fertilizers and pesticide raw materials. This research endeavors to conduct a comprehensive analysis of the composition of the flue gas washing liquid. The primary objective is to evaluate the potential utilization of its components as principal ingredients in pesticide formulations. To augment the effectiveness of the pesticides, supplementary active ingredients are incorporated, derived from various plant species recognized for their efficacy in combatting plant pests and insects. The extraction process involves combining the flue gas washing liquid with selected plants, such as bintaro fruit, garlic, citronella, neem leaves, and tobacco. This approach not only addresses the issue of environmentally friendly disposal of liquid waste but also provides a sustainable solution to meet the agricultural sector's demand for efficient pesticides.
