The pharmacist did indeed have a problem with overheating. To solve the problem with vegetable oil, it must be heated to at least 90 degrees Celsius. The problem was that it overheated. We worked on the problem with the auto mechanics department, and with young refrigerationist students who also worked on the circuit. We fixed it. We came up with other sequences, other ways of working, and as a result we no longer have problems with overheating or filtration. We were able to solve the pharmacist's problems. We went farther, because it was a problem with supply.
The difficulty, when you want to use vegetable oil, is obtaining it and finding a place to pick it up. We worked with our distribution network, and we industrialized the process. We believed in this process, because we know that we are not sending 90% CO2 into the atmosphere, because it is a biomass system. That means it is very important to take this material and to burn it. We believed in it because we saw that the residue had become a resource. We wanted to use it and for the vehicle we adapted to use it. Having adapted the vehicle, we were able to conduct what we call zero tests. We go back from scratch, we start over, we work on our product and we have it verified by the chemists at Thetford Mines—it's called Oleotek—who have also helped us process our oils.
