Full textAbstract:
The study determined the amount of heat energy (heat of combustion) produced per unit mass from coffee pulp and coffee husks to see if these can be used as alternative sources of energy. The samples were obtained from Mount Elgon areas in Eastern Uganda. The objectives determined the amount of heat produced per unit mass from coffee husk and pulp and compared the amount of heat produced per unit mass from the coffee husk and coffee pulp. The coffee husk and pulp were dried, ground and sieved using a 150 microns diameter sieve. The resultant powder was analyzed using IKA C200 bomb calorimeter. The Heat values produced per unit mass from coffee husk and pulp were 15.389KJg-1 and 13.755KJg-1 respectively. Further analysis showed that both coffee pulp and coffee husks could be used as fuels for renewable energy. However, from the findings, it is recommended that coffee husks should be preferred as a better source of fuel since it generated 1.634KJg-1 more energy than the coffee pulp. Comprehensive study should be carried out on the two samples to obtain a complete fuel description of the samples.

Full textAbstract:
Coffee husk and coffee pulp are coffee processing by-products. Coffee husk is obtained when harvested coffee is processed by the dry method, and coffee pulp is produced by the wet method. In Brazil, coffee is usually processed by the dry method, therefore an expressive amount of husk is obtained every year. Some of the husk is used as organic fertilizer but, other applications are very limited, mainly because it is a bulky product. The presence of tannins and caffeine diminish acceptability and palatability of husk by animals. This review discuss degradation of caffeine by microorganisms, with special attention to bacterial, biological decaffeination of coffee husk and pulp and its subsequent use on animal feeding. The known biochemical routes of caffeine degradation by microorganisms are initially discussed; problems concerning physiological effects in animals, focusing on the limitations imposed by caffeine as an antiphysiological component are raised; the use of microorganisms to decaffeinate coffee husk and pulp is discussed. The discussions offer a view on decreasing caffeine content of coffee husk and pulp, which would allow the use of larger amounts of these products in animal feeding, partially replacing traditional components such as cereal grains.

Full textAbstract:
Solid state cultivation (SSC) was carried out to evaluate the feasibility of using coffee husk and spent-ground as substrates for the production of edible mushroom Flammulina under different conditions of moisture and spawn rate. The strain of F. velutipes LPB 01 was adapted for a coffee husk extract medium. Best results were obtained with 25% spawn rate, though there was not much difference when lower spawn rates (10-20%) were used. Ideal moisture content for mycelial growth was 60% and 55% for coffee husk and spent-ground, respectively. With coffee husk as substrate, first fructification occurred after 25 days of inoculation and the biological efficiency reached about 56% with two flushes after 40 days. With spent-ground as substrate, first fructification occurred 21 days after inoculation and the biological efficiency reached about 78% in 40 days. There was decrease in the caffeine and tannins contents (10.2 and 20.4%, respectively) in coffee husk after 40 days. In coffee spent-ground, the tannin contents decreased by 28% after 40 days. These decrease was attributed to the degradation of caffeine or tannins by the culture because these were not adsorbed in the fungal mycelia. Results showed the feasibility of using coffee husk and coffee spent-ground as substrate without any nutritional supplementation for cultivation of edible fungus in SSC. Spent ground appeared better than coffee husk.
