Every year, billions of tons of agricultural waste, for example, rice husks, corn stalks, coconut shells, are either burned or left to decompose, releasing CO₂ and methane into the air. But what if these waste streams could be turned into clean, carbon-rich fuel, with 40% higher burn efficiency and 90% lower emissions? Study shows that substituting coal with biochar briquettes cuts methane and CO₂ emissions by ~40%. That’s the power of biochar briquettes—a revolution in sustainable energy and climate action. 

In today’s article, we will discuss what biochar is, the use of biochar, and how брикетирование help the use of biochar become easier. Let’s keep reading!

What is Biochar/Biocharcoal?

Biochar

Biocharcoal

Biochar is also referred as bio charcoal. Biochar is a stable, porous, and carbon-rich material produced by heating organic biomass in the absence of oxygen, a process called pyrolysis (organic substances decompse at high temperature (between 300-900℃) at low oxygen condition). Simply speaking, biomass is slow roasted into charcoal without flames. Bio charcoal is primarily used for soil enhancement, carbon sequestration, and environmental applications rather than filtration.

Raw Materials for Biochar

Typical feedstocks for biochar production include:

  • Agricultural residues: rice husks, corn stover, coconut shells
  • Forestry by-products: wood chips, sawdust
  • Other organic sources: animal manure, sewage sludge

These feedstocks determine the properties of the final biochar product.

Moreover, sustainable sourcing of feedstocks also ensures that biochar production remains environmentally friendly and economically viable.

How is Biochar Made?

Pyrolysis is the primary method of biochar production. During pyrolysis, biomass is heated at temperatures typically between 300–900°C in a low-oxygen environment. This process breaks down the organic matter, leaving behind biochar, volatile gases, and bio-oil.

The temperature and residence time influence the characteristics of biochar, including its porosity, surface area, and nutrient content. Higher temperatures generally produce biochar with greater stability and carbon content.

What is Biochar Briquette?

Despite raw biochar is often used directly, it can be challenging to handle and transport in loose form. This is where biochar briquetting comes in. Briquetting compresses biochar powder or granules into compact balls, bricks, or other shapes. This process involves high pressure and the addition of binder, at room temperature.

Briquetting technology on biochar can offer a lot of advantages to a better application.

  • Easier handling, storage and transportation (less dust)
  • Improved consistent combustion when used as fuel (Consistent shape and density)
  • Lower energy consumption (No drying needed, no heating needed)

Applications of Biochar and Biochar Briquettes

Biochar and biochar briquettes can be applied to various fields and industries. Here’s how biochar is making a difference across industries:

Work as Soil Amendment

Soil amendment is one of the key applications of biochar. Thanks to the porous, good hygroscopicity (water absorption), and high pH characteristics, biochar can help improve the porosity of soil, enhance the moisture of soil, neutralize the pH of acid soil, etc.

Work as Cleaner Fuel in Industrial Applications

Biochar briquettes are great substitue to replace fossile fuel in industrial use. For example, they can replace coal and coke in steelmaking. In steelmaking, coal and coke are used as fuel and reducing agent. However, using them in steelmaking can result in the generation of pollutants, such as CO2 and SO2. Biochar contains high carbon content and it features with high porosity and carbon neutrality. These features make it a great replacement for coal and coke. Nowadays, a lot of companies and enterprises are using biochar to lower the use of coal and coke.

Carbon Sequestration

Biochar is a stable material, which enables it to be stored in the ground for a long long time that locks CO2 in the air. In algricultural application, biochar can lower the emission of methane and N2O in the soil.

Because biochar is porous and stable, they are also used in many other industries including water management, etc.

Key Considerations in Biochar Briquetting

For successful biochar briquetting, several factors must be considered:

  • Feedstock Moisture Content: Optimal moisture ensures good compaction and minimizes energy consumption.
  • Binder SelectionChoosing the right binder for durability and performance that match your feedstock the best.
  • Equipment Type: Screw presses, piston presses, and roller presses are popular machines for briquetting.
  • Quality Testing: Standards for briquette density, durability, and combustion characteristics ensure product reliability.

Common equipments used in briquetting :

Hopper, Roller Press Machine (Briquetting machine), Mixer, Belt Conveyor, Dryer.

The Importance of Binders in Biochar Briquetting

Папки play a critical role in the production of biochar briquettes. Binders don’t just hold the particles together, they also help improve the briquette’s mechanical strength and durability, for example, with the right binder, the briquettes can be stronger in quality or resist high temperature in furnace. Common binders include starch, molasses, clay, lignin, water glass, etc.

When selecting a binder, we should consider several factors:

  • Dosage and Cost
  • Impact on Combustion and Emissions (Does it contain polluted substance?)
  • Compatibility with the biochar feedstock

The right binder ensures high-quality briquettes that meet energy and environmental standards.

While selecting the right binder is important, successful biochar briquetting requires more than just a material supplier. Differences in raw materials, moisture levels, particle size, and production equipment can all affect briquette strength and stability. Without proper testing and process optimization, many factories struggle with weak briquettes, cracking, or high production costs.
