Abstract: A method of forming a polyurethane foam article includes the step of forming a resin composition. The resin composition includes a polyol component, an amine catalyst, and a blowing component. The blowing component includes a hydrofluoroolefin and formic acid. The method also includes the steps of combining the resin composition, a recycled resin composition, and an isocyanate component to form a reaction mixture and discharging the reaction mixture to form the polyurethane foam article.
