Introduction

• M/s Saansera Farm2Fuel Solutions Pvt Ltd, a pioneer in sustainable energy solutions, has successfully developed a method to produce waterglass (sodium silicate) from biomass ash.
• With expertise in biomass supply chain management and innovative waste utilization, the company has conducted small-scale successful trials of this process. 
• Now, this Next-Gen start-up is looking for business collaborations to showcase this expertise and expand production capabilities.

Problem & Solution

• Biomass-based steam boilers utilizing rice husk, bagasse, and other agricultural residues as fuel generate a significant amount of ash as a byproduct. 
• Conventionally, this ash poses disposal challenges and environmental concerns.
• However, the high silica content in the ash presents an opportunity for commercial utilization—particularly in the production of waterglass. 
• Converting biomass ash into waterglass not only mitigates waste disposal issues but also creates an additional revenue stream.

Understanding Waterglass

Waterglass, or sodium silicate (Na₂SiO₃), is a versatile compound used across industries, including:

• Adhesives & Binders: In paper, cardboard, and textiles
• Construction: In cement and concrete formulations
• Detergents & Soaps: As a stabilizer
• Water Treatment: As a coagulant aid
• Foundry & Ceramics: For moulding and coatings

The Untapped Potential of Biomass Ash

• Biomass combustion produces a considerable amount of ash, much of which is often discarded without realizing its hidden value.

• This ash is rich in silica, an essential component in various industrial applications, including the production of waterglass, which is widely used in adhesives, detergents, coatings, construction materials, and even in green technology solutions.

   Composition of Biomass Ash

The ash generated from biomass-fired steam boilers, particularly from rice husk and bagasse, is rich in silica (SiO₂).

Typical compositions are:

• Rice Husk Ash (RHA): 85–95% SiO₂
• Bagasse Ash: 50–70% SiO₂

This makes them ideal raw materials for producing waterglass.

Process of Producing Waterglass from Biomass Ash

M/s Saansera Farm2Fuel Solutions Pvt Ltd has developed a proprietary process for converting silica-rich biomass ash into high-quality waterglass. This involves a carefully controlled sequence of purification, chemical treatment, and processing to ensure optimal yield and purity. Due to the proprietary nature of the technology, specific details remain a trade secret of the company.

The process generally involves:

• Pre-Treatment and Purification: The ash undergoes a refining process to remove unwanted impurities.
• Silica Leaching: Using an alkaline solution, the silica is extracted in a soluble form.
• Precipitation and Drying: The extracted silica is then converted into amorphous silica through controlled precipitation and drying.
• Waterglass Synthesis: The purified silica is further processed with sodium hydroxide to produce waterglass, a highly valuable industrial product.
