| Summary: | At present, there are major environmental problems that are caused by various factors, but mainly due to poor disposal and non-use of waste generated in industrial processes. For this reason, strategies have been advanced that seek materials of natural origin and take advantage of this type of waste. Coffee grounds (BC) are an organic waste that is commonly discarded in households and industries, without evaluating the environmental damage caused by the decomposition process of this waste, which overlays methane emissions a greenhouse gas. The purpose of this study is to obtain a material using the coffee grounds (BC) generated by the company CYGNI Ingeniería S.A.S.; for which the moisture content was 2.96 ± 0.12 %, ash 1.50 ± 0.02%, volatile matter 5.30± 0.98 and fixed carbon 90.00 ± 0.01% were determined. Furthermore, a particle size analysis was carried out, obtaining a particle size between 710 µm - 500 µm; subsequently, two materials were prepared in different percentages of BC (5% and 15%), pellets were obtained which had moisture values of 2.35 ± 0.05 (5%); 4.5 ± 0.05 (5%); 4.19 ± 0.06 (15%) and ashes of 0.05 ± 0.04 (5%) and 0.21 ± 0.04 (15%). Finally, printing tests were carried out using the pellets. The results obtained in this work contribute to identify the characteristics of waste such as Coffee grounds, in order to use them in the production of sustainable materials. |
