Müllplast is situated in Caxias do Sul, a city of the state Rio Grande do Sul (RS), in Brazil. The city was built where the Planalto de Vacaria begins to fragment into several valleys, crossed by small watercourses with the result of a very rugged topography in the southern part.
Since then, the city grew fast, multiplying its population, reaching high levels of economic and human development and making the economy one of the most dynamic in Brazil, present in many international markets.
