Every year, quantityagricultural wasteWaste generated after each crop season in our country is huge. However, more than 90% of these waste products are still treated in traditional ways such as burning and burying. This really causes quite a bit of waste. Because agricultural waste products can be used more effectively. In the following article,Microbial product Duc BinhShare with readers biological solutionsHow to handle agricultural wastehelps protect the environment most effectively.
1. What is agricultural waste?
Agricultural wasteThese are simply leftover products or waste that are not needed after agricultural production. They are mainly trash and organic waste products that can decompose quickly in the environment.
A large amount of organic agricultural waste is discharged every year in Vietnam
In our country, some common types of agricultural waste include straw, rice husks, sugarcane bagasse, tree bark, fruit peels, livestock and poultry manure, by-products in seafood processing, etc. These types of organic waste products are usually not as harmful as inorganic waste. If you know how to utilize organic waste, it will bring many benefits to the agricultural industry, as well as support many other industries.
2. Current status of reusing agricultural waste in our country
Every year, the estimated amount of agricultural waste generated by each person in Vietnam is estimated at about 1.3 tons. If we only count straw, the average waste volume is 400kg/person per year. In addition, 1 ton of livestock and poultry manure per person per year is included.
The amount of agricultural waste discharged in Vietnam every year is huge
Most of this waste has not been classified and collected properly. The common treatment method for waste products such as straw is incineration or burying, causing serious air and soil pollution. After each harvest, straw piles up in many rural areas. Indiscriminate burning of straw causes smoke to spread rapidly.
Besides burning, people in many rural areas in Vietnam also use chemical fertilizers and pesticides. This is the reason why the arable land environment is increasingly eroded and poor in nutrients.
Fully aware of this situation, in recent years, many scientists as well as authorities have encouraged people to handle organic waste more scientifically. Besides burning or burying, people should use microbial products to recycle agricultural waste.
3. Why should we utilize agricultural waste for biological compensation?
Instead of burning or burying waste, agricultural waste products need to be recycled. This is a sustainable direction that helps protect the environment as well as save on fertilizer investment costs.
3.1. Protect the environment more effectively
If agricultural waste is treated in the traditional way such as burning, the air and soil environment in rural areas will be seriously polluted, directly affecting public health. Because during the process of burning products, many harmful gases will be emitted into the environment. Such as CO2 gas, CO gas, NO2 gas.
Proper handling of agricultural waste helps protect the environment
On the other hand, dust and smoke from burning straw or other agricultural waste also causes obstruction of visibility and affects traffic activities in many areas. The atmosphere will then become stuffy and uncomfortable. More dangerously, the burning method of waste disposal also has the potential for fire if the fire is not handled promptly.
Therefore, to protect the environment as well as limit unwanted risks, people need to handle agricultural waste scientifically, avoiding abuse of burning.
3.2. Save fertilizer investment costs
Many scientists have long warned about the harmful effects of chemical fertilizers. However, for immediate benefits, most farmers still use chemical fertilizers for crop care.
However, chemical fertilizers can completely be replaced with microbial organic fertilizers composted from agricultural waste. Through the composting process at the right time and combined with appropriate biological products, people will create a nutrient-rich fertilizer that does not erode the soil but still helps plants grow. When making good use of waste products, investment costs for fertilizers are also significantly saved.
4. Some common methods of treating agricultural waste
Currently, agricultural waste products can be recycled and used in many different methods, including:
4.1 Compost into organic fertilizer
Previously, agricultural production still relied mainly on chemical fertilizers. However, if overused, these fertilizers easily cause soil erosion, reduce nutrients in the soil, and plants grow quickly but do not bring long-term results. On the other hand, using too much chemical fertilizer is also the cause of water pollution, directly affecting the health of people living in the surrounding area.
Waste from agricultural waste is composted into nutrient-rich organic fertilizer thanks to probiotics that help improve soil and provide nutrients for plants.
Instead of overusing chemical fertilizers, people should switch to using microbial fertilizers and compost from organic waste products. In particular, waste products such as bagasse, rice husk, straw, etc. can be composted into organic fertilizer, used to fertilize plants, stimulate plant growth as well as improve the soil environment.
Currently, the process of composting organic fertilizer from agricultural waste is quite simple, because there is the support of many types of microbial and biological products: trichoderma mushroom, composting product EMZEO, original Em product…

4.2 Production of biomass energy products
In addition to composting, agricultural waste is also currently used to produce biomass energy. Among them, biomass electricity is known as an environmentally friendly energy source. The raw materials needed for the electricity production process are usually straw, rice husks, and bagasse.
- Direct burning or gasification of biomass:Burn dry waste products such as rice husks and bagasse to generate heat or electricity.
- Pyrolysis:Decompose waste products at high temperatures in an oxygen-free environment to create biochar, bio-oil and syngas.
However, to produce biomass electricity, people need to build a professional factory system. Therefore, this method of treating agricultural waste is not yet widely used.
4.3 Making raw materials to serve some industrial production sectors
Agricultural waste is not a waste material if we know how to utilize it. For example, tree bark, sugarcane bagasse or sawdust are common materials used in industrial wood production.
- Paper production:Some types of tree residue and sugarcane bagasse are processed to make paper.
- Construction materials:Straw can be used as heat and sound insulation materials.
- Biochar:Products from waste pyrolysis, used to improve soil, sequester carbon and filter water.
In addition, many types of waste products are also important raw materials used in the livestock and poultry feed processing industry.
4.4 Processing agricultural waste as animal feed
Some agricultural waste products can be treated with biological enzymes to make food for livestock and poultry with the purpose of reducing animal feed costs and taking advantage of locally available resources.
- Ingredients:Straw, corn stalks, weeds, bagasse, banana trees, EMZEO fermented bran, molasses…
- How to do it:Waste products are processed using methods such as silage, alkalization or adding enzymes from biological yeast to increase nutritional value and palatability.

4.5 Some other handling methods
Besides composting and producing biomass energy, agricultural products can also be recycled in many other ways. For example, used for biological fermentation, used as raw materials in the construction industry.
5. Challenges in reusing agricultural waste
Although there are many potential benefits and methods, converting agricultural waste treatment methods in Vietnam still faces many barriers:
5.1. Technical and infrastructure barriers
- Lack of appropriate technology: Many rural areas do not have enough technology or specialized equipment to collect, classify and process waste products (e.g. straw crushers, large-scale composting systems).
- High initial costs: Investing in advanced treatment technologies such as biomass power generation or large-scale biogas systems requires high initial investment capital, which is difficult to access for individual farmers or small cooperatives.
5.2. Limited awareness and habits
- Burning habit: Burning straw has become a long-standing practice, both quick and convenient in the eyes of farmers, making it difficult to change habits.
- Lack of technical information: People lack knowledge about the technical process of effective organic composting with microbial products, leading to poor quality output products or the process being abandoned.
5.3. The problem of collection and transportation
- Large volume, bulky: Agricultural waste, especially straw, has a large volume but low density (bulky), making it difficult and costly to collect and transport to processing sites.
- Short crop season: Waste products are concentrated within a short time after harvest, putting great pressure on the purchasing and processing system.
