Product Details
Multi-Purpose Antioxidant And Environmentally Friendly Lignin
Liquid
Product Introduction
Lignin powder/liquid is a valuable byproduct of the pulp and paper
industry, derived from wood and straw, comprising about 20-28% of
their total mass. During the pulping process, lignin is extracted
as a significant byproduct of cellulose production. This versatile
material, after processing, is available as either a
yellowish-brown or reddish-brown powder or liquid, offering a range
of applications across various industries.

Key Applications
Agricultural Applications
Soil Enhancement and Nutrient Optimization
- Soil Structure Improvement: The unique porous and colloidal characteristics of lignin powder
enhance the aggregation of soil particles, leading to improved
aeration, moisture retention, and reduced compaction. This process
contributes to healthier root systems and better crop yields.
- Controlled-Release Fertilizer Carrier: Lignin acts as an innovative carrier for chemical fertilizers such
as urea and phosphates, allowing for nutrient adsorption and slow
release. This minimizes the risk of nutrient leaching, thereby
increasing fertilizer efficiency and sustainability.
- Boosting Organic Matter Content: As a natural source of organic carbon, lignin stimulates microbial
activity in the soil, promoting the accumulation of organic matter
and enhancing soil fertility over time.
Pollution Mitigation and Heavy Metal Passivation
- Heavy Metal Binding: The presence of functional groups like phenolic hydroxyl and
carboxyl groups in lignin allows it to chelate heavy metals such as
lead, cadmium, and arsenic, reducing their bioavailability and
toxicity in agricultural soils.
- Degradation of Pesticide Residues: Lignin promotes microbial metabolism, facilitating the breakdown
of persistent organic chlorine pesticides, thus aiding in
environmental cleanup.
Plant Stress Resistance and Growth Modulation
- Drought Resistance and Moisture Retention: When lignin absorbs water, it forms a gel that reduces water
evaporation from the soil, enhancing crops' ability to withstand
drought conditions.
- Induction of Disease Resistance: Certain lignin derivatives, such as lignosulfonates, can activate
plant defense mechanisms, helping to suppress soil-borne pathogens
like root rot and improve overall plant health.
Aquaculture Applications
Water Quality Improvement and Stability
- Adsorption of Harmful Substances: The porous structure of lignin powder effectively captures ammonia
nitrogen, nitrites, heavy metals, and organic pollutants, leading
to significant improvements in water quality for aquatic
environments.
- Suppressing Algal Blooms: Lignin can compete for nutrients or release algicidal compounds
(such as phenolics) to control excessive growth of harmful
blue-green algae, promoting a balanced aquatic ecosystem.
Feed Additive for Aquatic Animals
- Source of Dietary Fiber: Lignin serves as a crucial dietary fiber source for species like
grass carp and shrimp, enhancing gut motility and promoting good
digestive health.
- Immune System Enhancement: Lignin derivatives, such as sulfonated lignin, can stimulate the
activity of immune cells, improving the disease resistance of
aquatic animals.
Eco-Friendly Aquaculture Solutions
- Biodegradable Aquaculture Nets: Lignin can be combined with biodegradable plastics to create
sustainable aquaculture structures, significantly reducing plastic
pollution in aquatic environments.
Feed Applications
Functional Feed Enhancer
- Digestive Health Improvement: The fiber content in lignin powder can optimize rumen fermentation
in ruminants, enhancing the digestibility of roughage. In
monogastric animals, it promotes beneficial gut bacteria,
supporting overall gut health.
- Mycotoxin Binding: Lignin's ability to physically adsorb mycotoxins such as
aflatoxins and deoxynivalenol helps protect animal health by
mitigating the risks associated with contaminated feed.
Livestock Waste Management
- Odor Neutralization: When added to livestock bedding, lignin effectively absorbs
harmful gases like ammonia and hydrogen sulfide, leading to
improved air quality in animal housing facilities.
- Enhanced Manure Treatment: Acting as a composting agent, lignin accelerates the fermentation
process of manure, reducing pathogens and unpleasant odors, thereby
promoting a healthier farming environment.
Antibiotic Alternative Potential
- Antimicrobial Properties: Lignin contains phenolic compounds that exhibit inhibitory effects
against pathogens such as E. coli and Salmonella, offering a
natural alternative to traditional antibiotics and supporting
animal health.
