Produção de papel de bagaço de cana empregando um método mais sustentável.

Abstract

Given that, governments and societies are currently engaged in increasing the use of chemical raw materials that use renewable sources, as an alternative to various products. The use of oil and forest clearance products affects their environmental impact. In this study, it evaluated as sugarcane bagasse paper production, using different types of NaOH. The objective is obtaining a product for replace or replaced by eucalyptus paper as well as reducing the concentration of inputs in the wastewater, obtaining a more environmentally viable product. Experimental planning 22 was performed with the monitoring of time (hours) and NaOH concentration (0.5 M; 0.75 M and 1.00 M) for bagasse delignification under heating of 58 ° C for 30 minutes and the pulp produced the pulp papers. It was also performed the quantification of the bagasse washing water after the extraction of the line through the application of pH and the evaluation of applications of the applied papers. It was not possible to quantify a line removed from the black liquor using spectroscopy due to the methodology used. The bagasse papers were test in printing and photocopying, showing sharpness. Paper applications such as sugarcane filter filters, using chemical filters for physical use of raw filter chemicals and filters, it was possible to verify what occurred gradually in 7.1%, 8.2% and 8.8% of the ICUMSA color of paper filter filters used in 0.5 M screens; 0.75 M and 1.00 M, respectively.
