The pasta I ate was from longueil Quebec produced by a factory called  Giardino. The process of manufacturing pasta is one that uses a lot of energy because of the machinery involved. The machinery involved in pasta not only handles massive amount of semolina it also needs to be cut, rolled, pressed and its temperatures regulated at different part of the manufacturing process (pasteurization and drying). In addition packaging is usually taken care of right at the processing plant. Here is a short five minute video which shows some of the machinery involved in the process described above.
