This razor design challenges the “cradle to grave” manufacturing and use model of women’s disposable razors. Inspired by the safety razor, the permanent handle and removable blade system eliminates exposure to sharp edges during blade changes and optimizes blade recycling. Using life cycle analysis, the projected environmental impacts of her design proved more favorable after three years of use compared to typical use of disposables in that same timeframe. Considering many women shave from teen years through late adulthood, this design could reduce the two billion disposable razors Americans throw away each year.
