Bioethanol - or simply 'ethanol' is a renewable energy source made by fermenting the sugar and starch components of plant by-products - mainly sugarcane and crops like grain, using yeast. It is also made from corn, potatoes, milk, rice, beetroot and recently grapes, banana and dates depending on the countries agricultural strength.
Today, bioethanol has many uses: It is blended with petrol to make a truly sustainable transport fuel, it's used in cosmetic and other manufacturing processes, and it creates the clean burning, beautiful dancing flame in our fireplaces.
Bioethanol is completely composed of biological products. The combustion of bio ethanol results in a clean emission: Heat, Steam and Carbon Dioxide.
Carbon dioxide is absorbed by plants. It is then processed via photosynthesis to help the plant grow. This infinite cycle of creation and combustion of energy makes bio ethanol a carbon neutral fuel source.
Efficient Green Energy
Because the combustion of bio ethanol is clean you can lose the chimney and the flue and keep the heat - so most of the heat generated by the combustion of bioethanol gets to stay in the room - that's what makes burning bioethanol so efficient and effective.
A Beautiful Dancing Flame
Burning bio ethanol creates a beautiful lively dancing orange flame that is simply mesmerising. And because they don't need a flue or chimney you can now enjoy an open fire more easily than ever before - even in a high rise building.

The Plant is Self Supporting in Energy.
The main objective of this plan is the realization of a production plant in which cassava is converted into bio ethanol and residual material from the conversion of bio ethanol is used to produce biogas that will generate electricity and steam in a very efficient way by using best available technologies.
In this plant, elements of the second generation technologies for the production of bioethanol will be used, involving an unique enzymatic conversion of starch containing feedstock, the so called “non cooking process.
In addition to the “non cooking process, sophisticated techniques are implemented for distillation and drying of the bio ethanol. Combination of the “non cooking process and modern techniques for distillation and drying results in substantial advantages compared to conventional processes for the production of bio ethanol :
- Lower consumption of energy
- Lower investment costs
- Lower operational costs
The plant is designed to convert any inlet capacity of cassava roots start from 30 tonn per hour into bio ethanol. The bio ethanol plant is connected to a biogas plant with gas generators, that produce all the needed steam and electricity.
The biogas plant will produce electric power, that will be used in the plant. The biogas unit will be fed with the residue from the fermentation of bio ethanol. The production of bio ethanol, as described in this plan, contributes to several assigned governmental targets:
- Improvement of the agricultural industry, structure and perspective in Lampung.
- Structural improvement of regional employment. Local companies will be involved in construction and building of the plant.
- Improvement of infrastructure and local small businesses.
- No use of fossil energy for the production of bio ethanol.
A production unit will be built in which bio ethanol will be produced from cassava in the most efficient way and with the use of most modern technologies. In particular the process depends on application of the so called non cooking process, in which elements of the so called 2e generation technology for the production of bio ethanol are used. The process features:
- Consumption of less energy in the production process
- Significantly lower investment costs
- Substantial lower operational costs, compared with other processes for the production of bio ethanol , results in competitive final product.
The quality of bio ethanol is crucial. Contamination of the bio ethanol in the production process is prevented through the low pH in the fermentation process as well as the high alcohol content in the fermentation process. The plant will have a quality control laboratory that will monitor and control the quality of feed stock and final product. The quality of the produced bio ethanol will meet International standards
