Abstract |
|
|
| Date palm (phoenix dactylifera L.) is an important tropical fruit growing in North Africa and the Middle East, which is rich in sugar that offer Anaerobic fermentation after steps of treatment to produce bioethanol.
The purpose of the present research is to review the optimal ways to convert date seeds waste into useful products oil, bioethanol, carbon dioxide and fertilizer. Conversion of lignocellulosic agricultural waste into bio-oil, bioethanol and other valuable components will be discussed. These techniques reduce dependence on fossil fuels, emissions of harmful gases and promote the sustainability of natural resources, such as water, and reduce the landfills waste.
This idea encourages investors to invest in energy generation, pharmaceutical industry and other applications from these products. Date seeds are a good source of oil (5 to 13%) so value is added to the feedstock by extracting oil first from the seeds by Soxhlet apparatus and the remaining residue is the feedstock for the second pre-treatment. Utilizing date seeds waste for bioethanol production through Saccharomyces cerevisiae grown in yeast.
