INDUSTRIAL WASTE PROCESSING INTO ORGANIC FERTILIZER – A NEW DIRECTION IN GREEN TECHNOLOGY

1. Types of Fertilizers: Chemical Fertilizer, Organic Fertilizer, Microbial Organic Fertilizer

• Chemical Fertilizer: Chemical fertilizers are produced through industrial processes using natural or synthetic materials to provide essential and vital nutrients for crops. However, the use of chemical fertilizers poses several issues such as depleting soil organic matter, causing imbalances in field nutrition, and having negative effects on the ecological environment and soil physical conditions. Excessive use of chemical fertilizers can also lead to soil compaction.
• Organic Fertilizer: Organic fertilizer is a product derived from organic matter (such as animal manure, grass, plant residues) after the composting process. Organic fertilizers contain essential nutrients for plants and are environmentally friendly, contributing to the improvement of living and working conditions for workers while efficiently utilizing and managing industrial waste.
• Microbial Organic Fertilizer: Microbial organic fertilizer is organic fertilizer enriched with specific beneficial microorganisms. It undergoes a fermentation process using microbial technology, producing a product that contains both organic nutrients and beneficial microorganisms for plant growth.

In the current era of heightened human living standards, the demand for “green food” is growing. Crops cultivated using organic or microbial organic fertilizers not only ensure the nutritional and safety aspects of the products but also contribute significantly to addressing environmental issues.

2. Potential of Industrial Waste Processing into Organic and Microbial Organic Fertilizers

Every day, an immense amount of industrial waste such as animal manure, spoiled agricultural products, dried plant residues, and industrial wastewater (containing high levels of starch and protein) is released into the environment, causing severe pollution and incurring substantial treatment costs.

Developed countries worldwide have successfully utilized these waste sources to produce organic and microbial organic fertilizers. This not only addresses environmental concerns but also creates green products that provide nutrients to crops and improve soil quality.

Scientists have experimented with the benefits of organic and microbial organic fertilizers derived from industrial waste, including:

• No environmental pollution
• Scientifically controlled formulas for nutrient balance
• Improvement of soil organic matter
• Reduction in the use of chemical fertilizers, enhancing crop quality
• Prevention of diseases related to soil
• Enhancement of plant resistance, aiding in drought resistance
• Promotion of early crop maturity

3. Simple processing and production procedures

With the rapid development of machinery and technology, processing industrial waste into organic fertilizer is no longer a challenging problem. Depending on the input waste source, different catalysts and processing systems can be employed.

For example, with animal manure, straw, and green waste, the basic process includes mixing the input materials in appropriate proportions to achieve the desired C/N ratio, pH, and temperature. This is followed by a fermentation process (controlled for oxygen concentration, pH, and temperature, and may include the addition of catalysts and microorganisms to expedite the fermentation process), filtration, grinding, pellet formation, drying, cooling, and packaging.

4. Future Outlook for Vietnamese Businesses

Every day, thousands of tons of starch wastewater from food factories, animal blood from slaughterhouses, and organic waste are discharged into the environment, incurring significant treatment costs. If not treated properly, this can lead to environmental pollution.

However, these wastes contain valuable nutrients such as protein, starch, and organic nutrients. Enzymes, microorganisms, and technology can be used to hydrolyze and transform them into green products such as organic fertilizers.
