Bioenergy for sustainable development: An African context

Decentralised bioenergy systems: A review of opportunities and threats

“…The selection criteria was driven by the premise that the overall environmental, economic and social sustainability of any bioenergy system depends largely on the feedstock type, the conversion pathway, the business or production model involved, and end use application as documented in bioenergy sustainability criteria literature (e.g. Fritsche et al, 2006;Mangoyana, 2009;Smeets et al, 2005;Sridhar et al, 2006).…”

Potential of biodiesel as a renewable energy source in Bangladesh

“…Azad [19] has observed that 75.5% biodiesel production were obtained with 20% methanol. Jatropha plantation [106] can be established at a spacing of 2 m  2 m in a pit filled with soil, and the soil can be mixed with organic manure. Approximately 2500 plants per ha with the spacing mentioned above are needed.…”

Meeting the growing demand for food and bioenergy in the 21st century: synergies through efficient waste management

“…Bioenergy systems have the potential to interfere with food security in three ways: (1) diversion of food crops to energy use, (2) creation of competition for land, labour and capital between energy and food crops, and (3) increasing the prices for food through the increased demand of food crops [2]. When looking at possible alleviation of competing scenarios for food and bioenergy, two key options can be identified: efficient valorisation of organic waste streams, and cultivation of high-yield non-food crops suitable for application on degraded or marginal land.…”

“…Increasing need for food and energy security coupled with the need for climate change mitigation underscore the imperative for integrated and coherent policies that can stimulate sustainable growth and benefit the poor [2]. Applicable policies are essential for the effective and sustainable utilisation of water and agricultural waste for bioenergy production, food and environmental security.…”
