4dias-4solesA local enterprise seeks to provide a solution to the current problem in the central-southern area of ​​the country in the area of ​​heating and the environment, since at the national level there are a large number of saturated areas, 9 of the 10 cities with the worst air quality at the South American level, it corresponds to cities in the southern zone. The solution presented is the automated production of pellets for sale to locals in the area and private individuals. To start 4d-4s a pelletizer is required that meets a fixed production of 150 to 250 kg / h. The ideal thing to be able to supply the province of Ranco in the first place and over time achieve triple production to position itself at the regional level as a reliable product in quality and stock due to its high demand. The idea of ​​this project gave its starting point to fines for the year 2020, in which there was a total shortage of this fuel in the area, which forced the main points of sale to import.
