Plant materials pure lignin powder to support sustainable farming practices

Production Process
Lignin powder is a natural organic substance obtained by chemically or mechanically extracting and processing plant cellulose. It is primarily derived from plant materials such as wood and crop straw. During the production process, lignin undergoes meticulous crushing, drying, and screening to ensure its purity and uniform particle size, facilitating its use in various applications. Given lignin’s excellent biodegradability and environmental friendliness, environmentally friendly technologies are employed in the production process to minimize the impact on the ecosystem.

Product Composition

Main Application Areas
Lignin powder has a wide range of applications, including the following key areas:

• Agriculture: As an important component of organic fertilizers, lignin powder can increase the organic matter content of soil, improve soil structure, and promote plant growth. It also enhances the soil’s water retention capacity and helps suppress pests and diseases.

• Bioenergy: As a raw material for biomass energy, lignin powder can be converted into renewable energy through processes such as gasification and pyrolysis, providing a green alternative for the energy industry.

• Construction Materials: Lignin powder is widely used in construction materials, especially in cement and concrete, where it acts as a reinforcing agent to enhance the materials’ compressive strength and durability.

• Food and Feed: As a natural fiber supplement, lignin powder can improve the nutritional composition of animal feed, increase digestibility, and promote growth.

Usage and Dosage
The method of using lignin powder varies depending on the application area:
• Agriculture: Lignin powder is usually mixed with other organic fertilizers and applied according to the specific conditions of the soil. The recommended dosage is 10-20 kilograms per mu, but this can be adjusted based on soil test results and crop requirements.

• Bioenergy: In biomass energy applications, the dosage of lignin powder as a fuel or raw material varies depending on the conversion process. The optimal amount to add typically needs to be determined through experimentation.

• Construction Materials: When producing cement and concrete, lignin powder is generally added at a ratio of 0.5%-1% of the cement weight to enhance material properties.

• Feed: As a feed additive, it is recommended to add 1-3 kilograms of lignin powder per ton of feed, with the specific amount adjustable according to the type of animal and its growth stage.

Product Packaging and Storage
• Packaging: Lignin powder is usually packaged in multi-layer paper bags or plastic bags to protect it from moisture and contamination. Common packaging sizes include 25 kilograms per bag and 50 kilograms per bag, but custom packaging can also be provided according to customer requirements.
• Storage: Lignin powder should be stored in a dry, well-ventilated, and dark place to avoid damage from moisture and high temperatures. It is recommended to store it in a dry warehouse with a temperature not exceeding 25°C, and to keep it away from corrosive substances.
