There are numerous examples where hydrogen peroxide helps to prevent or reduce negative impacts on the environment. Furthermore, hydrogen peroxide is often regarded as a true “green chemical”. In contrast to many other red-ox agents, hydrogen peroxide introduces no additional substances other than water into the reaction system.
