See on page 22 the article “Copper tubes with soldered connections vs. carbon steel with mechanical coupling”, showing that, over the years, the copper pipes of automatic showers can present leaks due to welding failures in seams and connections. Carbon steel tubes with grooved mechanical coupling do not require skilled labor in assembly. Furthermore, on page 46, the article “Geomembranes HDPE as floating cover for odor containment”, presenting a real case study of a fertilizer industry in São Paulo countryside. The geomembrane solved the problem of bad odor and eliminated the risk of fertilizer percolation in underground and rainwater entering the reservoirs.
