“…Thus, the higher the density, the lower the relaxation ratio of the briquette will be and the better the stability of the briquette. Overall, compressed density obtained in both briquette types was less than the range of 0.98 to 1.12 g·cm -3 reported for bio-coal briquettes under moderate pressure (Wilaipon 2008). …”

The study was undertaken to investigate the properties of cassava starch and gum arabic bonded briquettes from the sawdust of Azadirachta indica. The briquettes were produced using a Jack press at an average pressure of 10.7 kg·cm -2 . The sawdust and binders were mixed at ratios of 100:15, 100:25, 100:35 and 100:45 in weight, respectively. The briquettes produced were subjected to physical and combustion tests. Both the physical and combustion properties of the briquettes vary with binder types and binder levels (p < 0.05). The result shows that briquettes bonded with starch gave better performance based on density of 0.546 g·cm -3 , durability rating of 95.93%, heating value of 33.09MJ·kg -1 , percentage of fixed carbon of 84.70% and low ash and volatile matter of 3.35% and 11.95%, respectively, while briquette bonded with gum arabic has density of 0.425 g·cm -3 , durability rating of 94.85%, heating value of 32.76 MJ·kg -1 , percentage of fixed carbon of 87.30% and low ash and volatile matter of 4.45% and 8.75, respectively. Since the aim of briquetting is to produce briquette that will serve as a good source of fuel and support combustion, the best briquette was produced when the sawdust-starch ratio and sawdust-gum arabic ratio was 100:25 and 100:35, respectively.

“…Yumak et al [26] produced briquettes from soda weed (Salsolatragus) to be used as a rural fuel source. [27] and the effects of briquetting pressure on banana-peel briquettes and on banana waste in northern Thailand by Weapon [28]. The study reveal that the pseudo stem briquettes showed higher compressive strength compared with leaves banana briquettes.…”

The effect on environment by agricultural and other industrial wastes is increasing and causing a lot of problems. It is estimated that about 500 million tons of agricultural and agro-industrial residues are being generated annually in the country. Adequate means of disposing these wastes are lacking, hence, converting them to value added products such as briquettes for domestic as well as industrial fuel is desirable. This study aims to establish a mix of options for organic waste processing that can deliver better economic and environmental outcomes than the production of low quality compost or other means that have limited market potential. The present review aims at summarizing value addition options for various biomasses towards energy production and value added product generation.

“…Based on a moisture content of 15%, the heating value is very close to that mentioned previously. Wilaipon [11] referred an average lower heating value of maize cobs of 14.2 MJ/kg, but the corresponding moisture content was not reported. In summary, the lower heating value of maize cobs is comparable with other crop residues and even above average.…”

Maize crop residues have great significance, particularly in developing countries, where the harvest of maize ears and their natural drying is widely applied. After drying and grain threshing, maize cobs are available for energetic use on farmers' yards. Shortcomings for their energetic utilization by combustion, in comparison with wood, are higher contents of potassium, chlorine, and nitrogen, and lower ash softening point. Tests in small wood chip boilers showed that the size of maize cobs should be reduced in order to facilitate better combustion and feeding with commonly used screw conveyors. Desirable length of particles should be 1-1.5 of their diameter. Within the framework of the Eureka project, a low-cost maize cobs crusher was developed and tested. It consists of a drum with six rows of knives, stationary comb-like knives, and a screen situated below the drum. The test resulted with working parameters that enable appropriate size reduction. Analyses of crushed material showed that over 80% of particles were in the range of 3.15-45 mm, less than 1% smaller than 1 mm, and less than 1% larger than 63 mm. This granulation is comparable with size class P45 for wood chips in accordance with standard DIN CEN/TS 14961. Further investigations should focus on improving the combustion facilities, in order to avoid formation of ash slag, and keeping exhaust gas characteristics within values defined by legislation.
