Porous polyurethane particle composition and methods thereof

A method comprising:

• providing a dispersed medium, wherein the dispersed medium comprises a hydrocarbon phase, water, and a polylactic acid filler;
• adding an isocyanate component to the dispersed medium such that polyurethane prepolymer droplets are formed, wherein the isocyanate component is immiscible with the hydrocarbon phase,
• wherein the isocyanate component is present in an amount ranging from 1 to 50 wt %, based on the total combined weight of the dispersed medium and the isocyanate component;
• and curing the polyurethane prepolymer droplets.
