“…Therefore, in the preparation of the LCA analysis it was assumed zero CO 2 emissions for PKS preparation for the torrefaction process. For the purpose of analysis it was also assumed that Malaysia has the largest production potential in the world [12] and produces 4 mln tons of PKS annually [13]. The palm oil production plant is Sri Kamusan Palm Oil Mill in Borneo.…”

This paper presents comparative life cycle assessment (LCA) for biomass use in the torrefaction process. The analysis took into account the climate change category for a time horizon of 100 years. It considered subsequent stages of biomass life cycle, i.e., the stage of biomass preparation for the torrefaction process, starting from its transport until its processing (thermal treatment) on torrefaction installation. Palm kernel shell (PKS) and Polish woodchips were selected as the biomass to be analyzed. The functional unit was selected to be 1 Mg of torrefied biomass. The torrefaction process was carried out in an installation at the Institute for Chemical Processing of Coal (ICPC).The analysis showed that among the considered life stages of PKS and woodchips, the biggest environmental load indicates the torrefaction stage. The estimated environmental effect is several orders of magnitude larger in comparison with other stages of biomass life.

“…Itam et. al [7] studied the density of PKS concrete and found out that it varies in the range of 1700 to 2050 kg/m 3 based on the type of sand used and the PKS contents. Generally, when concrete's density is lower than 2000 kg/m 3 , it is categorized as lightweight concrete.…”

This work is on the application of Artificial Neural Network (ANN) to study the effects of using palm kernel shells (PKS) as aggregates on the compressive strength of concrete. ANN with an input neuron of 6 factors, 2 hidden layers, 18 and 12 each and 1 output neuron for the compressive strength were used for this work. A mix ratio of 1: 1.5: 3 with cement content of 382kN/m 3 , water-cement ratio of 0.55 were used for the work, and cured for 90 days. A total of fifty concrete mixes containing PKS in various proportions of 0 % to 40 % by wt. of the coarse aggregate were used for the training. For the validation and testing ten mixes were used.. Therefore, sixty (60) data sets were generated for which approximately eighty (80) percent was used for the training, and twenty (20) percent for the validation and test. The results showed that the distribution characteristic of PKS-concrete using ANN is adequate for the prediction of compressive strength. The predicted and experimental results are strongly correlation, with a model equation with an intercept, 1.5 and a slope of 0.93. The characteristic distribution results of the predicted with the experimental showed that the parameter estimates (ANN and Statistics), are within the 95 % confidence limits (CI), and very significant (P<0.05).
