Prospect and application of flue gas washing liquid from wet scrubber unit at Masaro plastic refinery for organic pesticides

Abstract

Masaro plastic refinery represents an advanced technology designed to effectively manage residual waste. This innovative approach integrates the principles of incineration and pyrolysis to obtain valuable products, including fuel and flue gas washing liquid from a wet scrubber unit. The flue gas washing liquid contains ammonia, nitrates, nitrites, and phenol compounds which still do not meet the quality standards stipulated by the Ministry of Environment and Forestry. Those compounds should be reclaimed due to their toxicity towards aquatic organisms. Fortunately, they are extensively employed in the agricultural domain such as raw material for fertilizers and pesticides. This research endeavors to conduct a comprehensive analysis of the composition of the flue gas washing liquid. The objective is to evaluate the potential application of its components as main ingredients in pesticide formulations. To augment its effectiveness, supplementary active ingredients are incorporated, derived from various plant species recognized for their efficacy in combatting pests and insects. The extraction process combines flue gas washing liquid with selected plants, such as bintaro fruit, garlic, lemongrass, neem leaves, and tobacco. From the results, this research not only addresses the environmental issue but also provides a sustainable solution to meet the agricultural sector’s demand for sustainable pesticides.
