Characterization of Briquettes Produced from Groundnut Shell and Waste Paper Admixture

Desertification and deforestation are great problems facing developing nations. Adequate means of disposing wastes are also lacking، hence، converting them to other useful products such as briquettes for domestic fuel is desirable. The purpose of this work is to study some properties of briquettes made from groundnut shell and waste paper admixture with a view of addressing handling، transportation، and storage problems which is associated with biomass when used as fuels. Briquettes were manufactured using a motorized briquetting machine using five groundnut shells، waste paper mixing ratios (by weight)، i. e.، 10:90; 20:80; 30:70; 40:60; and 50:50. Obtained results showed that briquette produced using 10:90 waste groundnut shell - waste paper ratios exhibited the largest (though minimal) linear expansion on drying. While the compressed (maximum) density of the briquettes ranged between 627. 59 kg/m3 and 878. 10 kg/m3. For the relax density ranged from 281. 43 kg/m3 and 499. 38 kg/m3، there was little variation in the relax ratio of 2. 22 or 2. 23. The durability rating of the briquettes ranged in 55 and 91%. It was concluded that stable briquettes could be formed from waste paper mixed with groundnut shell of up to 20% groundnut shell admixture.
