MetadataShow full item record
Three recommended mixtures for briquette production were tested by eight identified informal waste workers within a 10-day briquette production test at the Calajunan dumpsite in Iloilo City, Philippines. The test revealed that Briquette 1 utilized a total of 127.50 kg dry waste paper; Briquette 2 was produced out of 183.80 kg of paper and sawdust while Briquette 3 was formed using 152.00 kg of paper, carbonized rice husk and sawdust. Briquette 2 produced the highest dry briquettes at 175.50 kg per 4.27 hr/day briquetting time followed by Briquette 3 at 142.74 kg for 4.18 hr/day and Briquette 1 at 122.25 kg for 4.19 hr/day. When all briquettes produced per day would be sold by the local waste worker’s association at a rate of Php15 (US$0.34) per kg, Briquette 2 would give the highest approximate daily earnings of Php263 (US$6). Heating value of the pillow-shaped briquettes produced ranged from 6,500 to 7,000 Btu/lb.
