Biochar Animal Feed – Application of Biochar in Animal Husbandry

As an emerging green material, biochar continues to attract people’s attention. Biochar is widely used in various fields, at the same time, related industries have been exploring its new uses. In recent years, biochar has also been widely used in animal husbandry: it can be added to feed for many benefits.

Why Choose Biochar as Feed Additive in Animal Husbandry

Biochar can be used as a feed additive in animal husbandry mainly because its structural properties play a major role. Biochar is a product made through a pyrolysis process. This process is usually carried out in biochar production equipment. Some of the structural properties of biochar are described below.

Highly Porous Structure

Biochar has a highly porous structure, which is caused by the volatilization of substances during pyrolysis. The porous structure endows biochar with good adsorption properties, which enables it to adsorb gases, liquids, and solutes.

High Specific Surface Area

The larger specific surface area helps to increase the contact area between biochar and other substances. Consequently, this also increases the efficiency of processes such as adsorption, catalysis, and ion exchange.

Good Chemical Stability

Biochar usually has high chemical stability, acid and alkali resistance, and thermal stability. This enables biochar to maintain its structural and performance stability under various environmental and application conditions.

Benefits of Biochar Animal Feed

Improve Digestive Health

Biochar has the ability to adsorb harmful substances. Biochar feed can eliminate the negative effects of bacteria, toxins, and heavy metals on the digestive system of animals. In this way, the digestive capacity of animals is improved.

Increase Feed Utilization

Biochar has the ability to adsorb and fix nutrients such as vitamins, minerals, and enzymes. Biochar animal feed helps animals absorb nutrients in the feed. This maximizes the availability of these nutrients to the animal.

Reduce Methane Production

Methane produced in the rumens of ruminants is considered a major source of greenhouse gases. By feeding biochar to cattle, part of the methane can be adsorbed in the biochar, reducing its amount entering the atmosphere.

Control Odor and Reduce Pollution

The good adsorption performance of biochar can absorb the harmful gas in the feces. In this way, feces odor and air pollution are reduced. At the same time, the addition of biochar can improve the quality of feces, which reduces the content of potential pollutants in feces.

Anti-bacterial and Anti-disease Effects

Biochar has a certain antibacterial ability, which can inhibit the growth and reproduction of some pathogenic microorganisms. Adding biochar can reduce the risk of disease in animals, optimize immune function, and improve the overall health of animals.

Contribute to Sustainable Development

Biochar is an eco-friendly material. Compared with traditional feed additives, the environmental impact of biochar animal feed supplements in the process of manufacture and use is relatively small, which is in line with the concept of sustainable development.

What Biomass Can be Used to Make Biochar

Wood and sawdust

Wood and sawdust are common sources of biomass, and biochar can be produced by wood charcoal making machine. Different wood species in various regions can be used to get biochar.


Crop residues

The residues of agricultural crops, such as straw, rice husk, and wheat straw, can be used as biomass sources. These crop residues are usually by-products of agricultural fields and crop processing.

Rice Husk

Fruit shells and plant skins

Fruit shells and plant skins, such as peanut shells, coconut shells, and nut shells, can be used as biomass sources. Most of them are abandoned and resources are relatively abundant.

Food processing waste

Waste from food processing, such as grape pomace, grape vines, and distillers grains, can be used as a source of biomass. These wastes are often rich in organic matter and can be converted into biochar.

Sewage sludge

Sewage sludge includes municipal sludge, river sludge and industrial sludge. Sewage sludge is rich in organic matter. These organic substances are key ingredients in the production of biochar.

Municipal domestic waste

Municipal solid waste contains a large amount of organic matter, such as food scraps, plant waste, and paper. These organic substances are the main raw materials for producing biochar.

How to Produce Biochar: Biomass Pyrolysis

Today, biomass pyrolysis has become the mainstream technology for producing biochar. This technology provides a sustainable solution for the management of waste biomass. Not only that, it produces high-quality biochar in an eco-friendly way. The following is the production process of biochar.

  1. Raw material preparation: First, biomass raw materials need to be collected and pretreated. These raw materials are crushed and dried to better suit the pyrolysis process.
  2. Feed and heating: The pretreated biomass is fed into a biomass pyrolysis plant, usually in batch or continuous mode. The equipment will provide a suitable temperature and oxygen-deficient environment. The pyrolysis reaction is promoted by heating the raw material at high temperature.
  3. Pyrolysis reaction: In a high temperature and oxygen-deficient environment, the organic substances in the raw material undergo a pyrolysis reaction. During this process, organic matter breaks down into gaseous, liquid and solid products. Among them, the solid product is biochar.
  4. Combustion control: During the pyrolysis process, the combustible gas produced can be used as fuel to provide heat to maintain a suitable temperature. The equipment will carry out combustion control to ensure the stability and high efficiency of the pyrolysis process.
  5. Product collection and processing: After the pyrolysis process, the biochar is collected and separated. At this point, other by-products such as wood vinegar and tar are produced. These by-products can be further processed or utilized.

If you want the livestock to grow better, the biochar added to the feed must be of high quality. Therefore, a biochar production equipment that can produce high quality biochar is essential.
