ABSTRACT

The decrease in availability of fuel wood and rise in prices of fo~sil foels in Nigeria calls for

considering alternative sources of energy for domestic and industrial use. This project was carried

out in order to design and develop a low cost briquetting machine for rural communities. It involves

the modificaion of hand use in producing briquettes by employing the use of hydraulic jack,

moulds, pistons etc. This method is faster and easier. The agricultural residue used was 80%

sawdust and a mixture of5% ash and 15% of cassava waste as binder. Performance characteristics

were evaluated based 011 the compressive test, durability test, watef boiling test for cold and hot

start done. The calorific value of 15,774 kJ/kg was given. Aiialysis between sawdust and firewood was done, which showed that sawdust briquette is healthier and economical.
