“…The rachis, pseudostem, leaf sheath and peel are the parts of the banana plant containing the largest amount of fibrous material. Due to their potential use as reinforcing components in high-performance composite materials, these cellulose-rich sources are currently being tested as heavy metal-adsorptive material in wastewater treatment, and as feedstock for bioethanol production (Bouallagui et al, 2005;Velásquez-Arredondo et al, 2010).…”

Banana is an agricultural product of great economic importance for various developing countries. The relationship between moisture content and water activity provides useful information for the processing and storage of banana waste. The water activity and moisture content of three banana (Mussa spp. Haploid AAB cv. Nanica) waste items were analyzed to determine the desorption isotherms at six different temperatures (20, 30, 40, 50, 60 and 70°C). The desorption isotherms of the peel, pedicel and pulp of overripe bananas were determined in wide ranges of moisture content (0.001-6.360 kg kg-1 d.b.) and water activity (0.02-0.907). The theoretical GAB model was used for modelling the desorption isotherms. An analytical solution of the Clausius-Clapeyron equation was proposed to compute the isosteric heat of sorption, the differential entropy and Gibbs' free energy by way of the GAB model when the effect of temperature on the hygroscopic equilibrium was considered.

“…Fertilizer is the next biggest contributor. The obtained estimate for R E is marg inally h igher than for corn ethanol, possibly due to the fact that farming is very labour intensive in St. Lucia but is similar to values for banana fruit shown by [31]. The value is within the range for corn ethanol [1,10] but would vary depending on actual farming practices used.…”

There is much in the scientific literature regarding the energy value of bioethanol, whether it is sustainable as a transition fuel and what impacts the production could have on food resource availability. This paper addresses these issues through the development of an energy self-sufficient ethanol plant. The plant utilizes waste Musa spp (banana) as the feed stock thereby making no additional demands food production. Solar energy and bioenergy provide thermal and electrical inputs to the process. The energy return on investment for this plant was calculated and a financial model drawn up to determine the economic feasibility of the plant. In one scenario, the operational cost of ethanol production is £0.39/litre with a profit before tax of £44,000 per year for a 460,000 lit re facility. This scenario results in a maximu m selling price for ethanol of £0.45/ litre at an IRR of 11% for a 15 year operation which is comparable to current petrol prices. Furthermore, the process used is very simp le and appropriate for s mall developing countries. The study focuses on the island of St. Lucia which is a banana producing state in the West Indies and concludes that establishment of an ethanol plant is possible with the right financial support with the benefit of reducing imports of petroleu m products, improving the balance of payments and creating emp loyment.

“…These biomasses help to recycle atmospheric carbon, minimizing global warming impacts since zero net carbon dioxide is emitted during biomass combustion. For instance, the amount of carbon dioxide emitted is equal to the amount absorbed from the atmosphere during the biomass growth phase (Van De Broek et al 1996;Velásquez-Arredondo et al 2010). The recycling of biomass waste reduces the need to create new landfills and extends the life of existing landfills.…”

“…Furthermore, biomass energy has several unique advantages. Biomass fuels produce virtually no sulphur emissions and help to mitigate acid rain (Arndt et al 1997;Velásquez-Arredondo et al 2010). These biomasses help to recycle atmospheric carbon, minimizing global warming impacts since zero net carbon dioxide is emitted during biomass combustion.…”

The Prospects of Rubberwood Biomass Energy Production in Malaysia

Rubber has been shown to be one of the most important plantation crops in Malaysia, and rubber tree biomass has widespread applications in almost all sectors of the wood products manufacturing sector. Despite its abundance, the exploitation of rubberwood biomass for energy generation is limited when compared to other available biomass such as oil palm, rice husk, cocoa, sugarcane, coconut, and other wood residues. Furthermore, the use of biomass for energy generation is still in its early stages in Malaysia, a nation still highly dependent on fossil fuels for energy production. The constraints for large scale biomass energy production in Malaysia are the lack of financing for such projects, the need for large investments, and the limited research and development activities in the sector of efficient biomass energy production. The relatively low cost of energy in Malaysia, through the provision of subsidy, also restricts the potential utilization of biomass for energy production. In order to fully realize the potential of biomass energy in Malaysia, the environmental cost must be factored into the cost of energy production.
