AB This paper reports on the influence of independent variablesin the ethylene glycol/soda pulping of olive woodtrimmings (165–1958C, 30–90 min, ethylene glycol concentration5–15%, soda concentration 2.5–7.5% and liquid/solid ratio 4–6), on the yield and Kappa index of thepulps and the strength properties (breaking length, burstindex and tear index) of paper sheets. By using a centralcomposite factorial design, equations that relate eachdependent variable to the different independent variableswere obtained which reproduced the experimental resultsfor the dependent variables with errors less than 12%.Using a temperature of 1848C, ethylene glycol and sodaconcentrations of 15% and 7%, respectively, a liquid/solidratio of 5:1 and a cooking time of 30 min results inyield, Kappa index, breaking length, burst index and tearindex values that depart by 14.3%, 8.2%, 17.1%, 17.0%and 2.3%, respectively, from their optimum levels. Theseconditions result in substantial savings in power consumptionand immobilised capital investments as theyinvolve a lower temperature, a lower liquid/solid ratio,and a shorter time than the maximum values tested.
