Microdroplet emulsion technology for pesticide residue removal from agricultural equipment

Overview

This solution proposes a novel, environmentally friendly method for removing pesticide residues from agricultural equipment surfaces using microdroplet emulsions. By combining oil and water phases at micro-scale sizes, the technology exploits the strong electric fields generated at droplet interfaces to effectively interact with and remove pesticide residues. The use of edible oils as the oil phase ensures the cleaning process has zero environmental impact, making it a sustainable alternative to conventional chemical cleaning agents. This approach addresses a critical challenge in the agricultural sector, where pesticide residues on equipment can pose contamination risks and regulatory compliance issues.

Technical specifications

• Microdroplet emulsion formulation: Combines an edible oil phase with water to create micro-scale droplets that interact effectively with pesticide residues on surfaces.
• Enhanced electric field effect: The micro-sized oil-aqueous phase interfaces generate strong electric fields at droplet surfaces, which contribute to more thorough removal of pesticide residues.
• Environmentally benign process: Uses edible oils and water, resulting in zero environmental impact and eliminating the need for harsh chemical solvents.
• Applicable surface compatibility: Designed for use on plastic surfaces commonly found in agricultural equipment.
• Planned validation methods: Physico-chemical characterization including contact angle measurements, thermogravimetric analysis (TGA), and nuclear magnetic resonance (NMR) spectroscopy to assess residue removal effectiveness.

Technology readiness level

This technology is at an early conceptual stage (TRL 1-2). No preliminary experimental data is currently available. The proposed validation plan consists of two stages: Stage 1 involves applying pesticides to plastic surfaces and conducting baseline physico-chemical characterization; Stage 2 involves washing the treated surfaces with running water and microdroplet emulsions, followed by characterization to quantify any remaining pesticide residues. Further research and experimental validation are needed to demonstrate proof-of-concept and optimize formulation parameters before commercial development.
