    Efforts to measure efficiency of mechanical pulping directly were conducted by determining the lowest limit of energy to produce SGW. Using a specially constructed grindstone at low rotational speed, Salmen et al. (1999) produced paper-grade pulp at 700 kWh/t, giving an efficiency of about 50% based on the conventional energy of 1500 kWh/t.
