The Biomass Gasification Technology

BSD has elected the biomass gasification technology as its core business because believes that this is the one that best can meet the practical energy needs of small rural villages of developing countries in their struggle to make their economy become sustainable.


The Gasification Technology supplied by BSD and designed and manufactured by its associate BioTherm Industries has overcome past technical, operational, and commercial hurdles that have often caused general reluctance towards this type of technology. The Syngas produced using BioTherm Industries' gasification plants is uniquely reliable, tar free, and competitive as renewable fuel.

Benefits of Biomass Gasification

  • Inclusive project that develops rural economy, its modular size fits well with the needs of the typical rural village in African and Asian continents.
  • Provides an eco-friendly, efficient utilization for agricultural residues otherwise burnt in the fields.
  • The by-products (cogeneration heat and biochar) of one single Biomass Gasification Plant of 1.0 MWe capacity can support the production of 200 Refrigerated Tons of Cold Storage, and 10,000 tons of organic compost.
  • Can produce biochar compost that reduces by half the requirements of chemical fertilizers in the cultivated fields and increases the water holding capacity of the soil thus reducing irrigation water by 20 %.
  • Every single Biomass Gasification Plant of 1.0 MWe can provide direct local employment for about 100 people

Advantage over other technologies

  • Carbon negative, compared with carbon neutral of Solar, Wind, and Hydro.
  • Round the clock Technology unlike Solar and Wind.
  • Biomass Gasification provides commercially viable solutions for industrial power generation below the threshold of 5.0 MWe where conventional power plants are no longer competitive on a capital unit cost basis.
  • Lower capital cost compared to other renewable technologies
  • BSD utilized gasification Technology of Biotherm Industries is entirely made in India, thus offering unbeatable competitive prices while still providing western type, high quality standards.

Biomass-to-Energy. The process used by BSD



BSD actively works on the promotion and utilization of the innovative Stalk Fractionation Technology designed and fabricated by its associated company BioTherm Industries. Due to the more efficient utilization of the natural resources of the stalk, this technology allows increased profit margins in the cultivation of crops that often necessitate government's subsidies to survive.

The stalk of sugarcane and sweet sorghum is the typical feedstock used in the sugar and bio-ethanol industry to extract the fermentable juice. The residual fiber after the milling process, is known as bagasse. This process waste is generally used as biomass fuel.

With the fractionation technology, the material components of the stalk are neatly separated into fractions that can be easily processed into further value-added products. The fractionation does not produce bagasse. The fractionated products are shown below:

Notions about the Stalk Fractionation

Is the hard, wood-like outer section of the stalk containing all the structural rind fiber.
Is the soft interior pith fiber of the stalk containing the high purity juice bearing cells
Is the sugar juice extracted from the pith containing the high purity juice.
Is the thin epidermal layer encasing the rind containing the abrasive mill-wearing silica, dirt, color, and most of the compounds contributing to the formation of molasses. Most importantly, it contains all the valuable natural wax in the stalk.

The Stalk Fractionation and its value-added applications potential.

Stalk Fractionation

Benefits of the Stalk Fractionation.

  • Eliminates crop material waste and permits optimized material utilization.
  • Increases the profitablility of the crop since enables the production of high value-added co-products.
  • Produces higher purity juice resulting in superior sugar quality and boiling house operational efficiencies.
  • Allows customization of the end-product mix to meet the specific needs of the market place.
  • Can process similar fiber crops such as sweet sorghum, hemp, sunflower, tobacco, jerusalem artichoke and kenaf with little or no equipment modifications.

Fractionation Plant Design & Manufacturing.

The standard configuration of the Fractionation System consists of six processing stations interconnected sequentially by speed controlled material handling conveyors

10 kg/h standard module
20 kg/h standard module

Larger size plants use multiple modular assembly of the above standard sizes.
