Unit 5 Treatment On Solid Pineapple Waste

Conclusion and Suggestion

5.1  Conclusion

Among the three pre-treatment methods conducted in this research, each of them have their own special characteristics in terms of lignin removal, lignin degradation, preservation of sugar, and personal performance of the work load.  In the detection and recovery of sugar concentration, it can be clearly justified that biological pre-treatment is the most suitable for solid pineapple waste.  This is due the prominent factor of the P. chrysoporium.  In terms of monitoring the quality of the parameters of the biological pre-treatment, such as enzyme activity, cellulose content, and types of sugar produce, biological pre-treatment much more suitable. In the biological pre-treatment, fructose was the most abundant type of sugar recovered, which was 14g/L in a gram of pre-treated sample.  As in for overall reducing sugar content, almost 3.5 g/L of reducing sugar was detected through the DNS method.

As for the chemical pre-treatment, the alkaline solution with 1% (v/v) concentration, reducing sugar was able to recover sugar. The acid solution was not a good solution for the pre-treatment of solid pineapple waste as the sugar recovery was 0. In the physical microwave pre-treatment, both 1 and 3% of NaOH concentration could detect the sugar. The sugar amount was very low compared to the amount of sugar recovered from biological pre-treatment.

In the future research, a broader parameter of solvent with much more intervals of radiation time should be carried out in order to detect a much higher concentration of sugar. The microwave pre-treatment is very suitable compared to biological pre-treatment, if an industrial level production is carried out. This is due to its convenience, shorter process time and less cost production.

5.2       Suggestions

 The effect of three kind of pre-treatment on solid pineapple waste was studied in this research. However, there is always a large room of improvements in order to obtain a much higher quantity of sugar and a better degradation of lignin, cellulose and hemicellulose.

The improvement of this research can be focused from the drying method of the solid pineapple waste. During this research, the drying of the pineapple waste was tedious. At times, it gets really dried up and at times it gets burned. A study could be focused on determining the suitable method and temperature of drying the solid pineapple waste. This is because, majority of the sugar disappears during the drying of the solid pineapple waste. A high amount of sugar could be recovered from an improved method of drying the biomass.

In the chemical pre-treatment of the solid pineapple waste, the range of the acid and alkaline solutions should be varied. This is because, the range of the chemical solutions was determined from research of other biomass. The amount of sugar recovery was more in the low concentrations of the chemicals. Thus, a parameter of lower concentration of chemical solutions should be focussed for the pre-treatment of solid pineapple waste.

Finally, In the biological pre-treatment, the range of spore count should be varied. This could really help in retaining much higher sugar level and the degradation of the lignin structures.
