Investment Opportunities in Biofuels

In view of the increasing environmental concerns particularly relating to the use of fossil fuels, new solutions to minimize the greenhouse gas effect are continuously sought for. Among the options, biomass has been recognized as the most important energy source for biofuel production to mitigate greenhouse gas emissions (Khan et al. 2009). Furthermore, increasing energy security fears, rising petroleum prices, […]

Concrete Materials

In the palm oil mill, the boiler ash (from PPF, PKS and EFB) creates a lot of envi­ronmental problems as their disposal methods are unsafe. The ash is normally dumped at landfills without any sustainable means of utilising it. Recent studies have reported many different ways of transforming the palm ash to value-added products such as concrete materials which are […]

Biodiesel Production Costs

The world biodiesel production was rapidly expanded with shocking increment of 5,000% from years 2001 to 2006 (Szulczyk and McCarl 2010). These figures are likely to increase further, due to active support from many countries (the European Union, the United States, Brazil, China, India, and some Southeast Asian countries such as Malaysia and Indonesia) which accelerate the biofuel production. Efforts […]

Prospect of Biodiesel as Renewable Energy Sources

Alternative fuels for diesel engines are becoming increasingly important due to diminishing petroleum reserves. The U. S. Energy Information Administration declared that total world energy consumption in 2005 was 488 EJ (exajoule, 1018J) or 463 Quad (quadrillion Btu, 1015 Btu). World consumption is expected to surpass 60% increase in energy consumption or equivalent to 650 EJ by 2025, and this […]

Enzymatic Process for Biodiesel and High Value-Added Products

George Chou Abstract An enzymatic biodiesel process can not only overcome the challenges faced by conventional chemical processes but also pave the way for versatile products to be coproduced from the same feedstock source. However, this is only possible and cost-effective through the right enzymatic process. This paper intro­duces a patented process that can meet these criteria, the ET Process®. […]

Fermentation Study on Macroalgae Eucheuma cottonii for Bioethanol Production via Varying Acid Hydrolysis

Rachel Fran Mansa, Wei-Fang Chen, Siau-Jen Yeo, Yan-Yan Farm, Hafeza Abu Bakar, and Coswald Stephen Sipaut Abstract The depletion of fossil fuel and the increase of human population lead to the search for more sustainable alternatives. Currently, bioethanol is produced from land-based crops, but in the future, marine biomass could be used as an alternative biomass source because it does […]
