The observed linear expansions were generally minimal. Briquettes produced using 100% waste paper and 5:95 waste paper-coconut husk ratio respectively exhibited the largest linear expansion (about 9%), while those manufactured at 15:95 and 25:75 ratios exhibited the least expansion (about 3%). What this finding seems to suggest is that the coconut husk perhaps had some stabilizing effects on the briquettes. Bruhn et al (1959) had observed that the type of material briquetted is one of the factors that have appreciable effects on product expansion.
