With many of the poor people in Brazil living in rural areas, local governments have intensified their efforts to design and implement effective policies that boost rural development. In 2004, a national program for production and use of biodiesel was launched aiming at increasing income among...

Environmental concerns and the rising cost of crude oil have incentivized the search for alternative aviation fuels. However, any potential alternatives must be thoroughly characterized and tested. In this investigation nine potential biofuels derived from sustainable sources were tested for...

To select microalgae with a high biomass, chlorophyll a, lipid, and fatty acid content of two mutants (LARB-202-2 and LARB-202-3) and their parent wild type of the unicellular green alga Nannochloropsis sp were cultured with air containing 1% CO2 for a week in 1L bubbled tubes with continuous...

Dual-injection strategies in spark-ignition (SI) engines allow the in-cylinder blending of two different fuels at any blend ratio, when simultaneously combining port fuel injection (PFI) and direct-injection (DI). This offers increased flexibility and the potential to optimize the combustion...

Botryococcus braunii (B. braunii), a green colonial microalga, is one of the most potentially significant renewable energy sources, because of its high productivity of hydrocarbon oils. In order to maximize energy utilization from this alga, it should be important to recover energy from not only...

The aim of this study was to evaluate the effect of microwave pretreatment on the solubilisation and anaerobic digestion of microalgae–bacterial biomass cultivated in high rate algal ponds for wastewater treatment. The microwave pretreatment comprised three specific energies (21,800, 43,600...

Grass biomethane has been shown to be a sustainable gaseous transport biofuel, with a good energy balance, and significant potential for economic viability. Of issue for the designer is the variation in characteristics of the grass depending on location of source, time of cut and species....

Camelina sativa (L.) is a promising crop for biodiesel production that avoids many of the potential pitfalls of traditional biofuel crops, such as land use change (LUC) and food versus fuel. In this study the environmental viability of camelina biodiesel was assessed using life cycle analysis...

The use of biofuels for road transport in Sweden has increased during the past 10years as policymakers stimulate demand in response to concerns about climate change. Using a supply chain approach, this paper analyses: (i) existing biofuel supply chains in Sweden (biogas, biodiesel and...

Increasing microalgal starch content by nutrient limitation has been regarded as an affordable approach for the production of third generation bioethanol. This work evaluated starch accumulation in Chlorella vulgaris P12 under different initial concentrations of nitrogen (0–2.2gureaL−1) and...
