Converting Agro-Industrial Waste
To Bio Ethanol (WTBE)
Bio Conversion Process
Bioducts’ WTBE technology uses a patented process to produce a variety of materials, fuels and chemicals from biomass using a pressurised heat processing system. The WTBE process sequentially fractionates biomass into its component parts. The primary products are dry low-ash biomass solids and sugars to produce commodity chemicals. The bio-conversion product consists of Cellulose and Lignin both of which are considered a valuable raw material. Further refining into wood composite materials, and fuels for use in power generation, transport, and other industrial energy demands. The key to the WTBE process is the use of a series of continuous high-pressure streams in which the temperature of the raw material is raised in stages. The core of our WTBE bio-refineries consist of a continuously operated aerobic fermenter in which microorganisms are converting the hemicellulosic carbohydrates resulting from hydrolysis, into bio-products, CO2, water and bioethanol.

Principles of BioDucts' WTBE Technology
Recycled Water
BioDucts' bio-conversion process pretreats lignocellulosic biomass to alter structural characteristics of biomass and increase the gluten and xylan accessibility for hydrolysis process. Fermentable sugars generated through hydrolysis process are then converted to ethanol employing fermenters using microbial biocatalysts.

Delivering Bioethanol Fuel
Technology Specifications
Bioducts’ WTBE technology is based on microorganisms that lives at high temperatures and that convert biomass based resources into valuable products rapidly and without creating pollution by-products. Bioducts’ technology can ferment all edible and non-edible sugars which present in biomass.
Key features of our technology are
(i) genetically engineered microorganism
(ii) its proprietary genetic engineering technology
(iii) its application in a continuously operated high efficiency fermentation process.
The core of the refinery consists of a continuously operated anaerobic fermenter in which then are converted to microorganisms. The hemi cellulosic carbohydrates resulting from the hydrolysis into Bioethanol, carbon-dioxide, protein-rich animal feed and recycled water. The microorganisms are continuously concentrated and re-circulated by a centrifugal separator to maintain a high cell density in the fermenter.

Bioethanol-Gasoline Blend (E85) Vs. Conventional Fuel
BioDucts' WTBE technology delivers bioethanol fuel via well-established pre-treatment process of lignocellulosic raw materials followed by fermentation. Bioethanol fuel with ethanol content of 35-85 vol% containing ethyl alcohol as the main compound is a well-known alternative renewable fuel to gasoline fuel to sustainably meet the energy demands of the present and future. Application of bioethanol fuel is increasing due to its attractive potentiality compared to the gasoline fuel such as
-
Higher octane number (108 vs. 95-98)
-
Higher enthalpy (heat of evaporation)
-
Lower vaporisation pressure
-
Broader ignition boundaries
-
Lower emission of greenhouse gases (GHG)
-
More favourable future revolution and
-
Greater environmentally sustainability of feedstocks being obtained to produce bioethanol
