Production and characterization of briquettes made from rice straw and sawdust under high pressure and high temperature conditions

Briquettes offer good value in terms of energy density. Briquetting sawdust with paddy straw is a ray hope for waste utilization, which has been burning issue India long time. A commercial briquetting machine was used to make briquettes two different forms—shredded and chopped, ratios, separately. The ratio increased until the produced had an acceptable firmness. maximum shredded possible 40:60 sawdust, whereas chopped it 60:40 sawdust. were then analysed properties assess their quality durability. shatter index varied from 0.10–10.12% 0.26–4.54%, respectively. friability range 93.54-99.85%, 89.89-99.90%. volatile matter ranged 79.60-83.89%, 76.69-86.07 %. ash content 9.83-13.07%, briquettes, 6.60-16.44%. fixed carbon 0.09 0.87%, 0.11 0.59%. results suggested that densification experiments successful
