Dates are distinguished by the fact that they contain sugar and vitamins, and these elements are the essential elements necessary for the growth of microorganisms, especially yeasts that are used in the production of ethanol.
Ethanol Production from Dates
It is a partial alternative to fossil hydrocarbon, which is known as (gasoline). Ethanol is produced from low-priced dates or second-rate dates that are not intended for human consumption, as it is produced from the waste of palm trees.

Advantages of Producing Ethanol from Dates
- Petroleum companies are allowed to export additional large quantities of refined petroleum products (fossil fuels).
- Increasing economic income.
- Creating a clean environment in which humans, animals, and plants can live. For example: When 5% of the vehicle’s fuel is replaced with ethanol, it will help reduce carbon monoxide from the air by 30%.
- Provides jobs.
- Establishing a large network for distributing liquid energy.
- Preserving the environment.
- Recycling the ethanol manufacturing waste and using it as animal feed, and thus the area of agricultural land used to grow grains designated for livestock will be reduced, and thus these areas will be used to grow crops for human consumption.

The Disadvantages of Producing Ethanol from Dates
Increased food crisis and lack of availability.
The greenhouse gases cause global warming.
Bioethanol
It is extracted from natural sources by biological processes, so it is used as an energy source and is currently one of the greatest discoveries in the field of alternative energy and reducing the proportion of toxic gases resulting from the combustion of fuel, which negatively affects the ozone layer and causes global warming.

How to Produce Ethanol from Dates
The juice of dates which is produced from some kind of molasses at a concentration of 70%, can be prepared in more than one concentration (50, 100, 200 and 300 g / l).
The optimum conditions for fermentation from the heat, pH, and concentration of the sugary substance, and the fermentation process will be carried out in anaerobic conditions at a temperature of 30 ° C. for 48 hours, and the cells are to be collected by centrifugation at 4500 cycles and for a period of 15 minutes, the fixation was carried out by the holders of Sodium alginate by placing it in a glass tube along its length 50 cm in diameter and 4 cm in diameter with a flow velocity of 6 ml/hour.
