Vietnam is a country with strengths in the agricultural industry, with biomass sources from by-products of agriculture, etc. Therefore, it will cause waste if people do not use resources properly. Moreover, it causes pollution if they do not manage it properly. And in this article, BioFix Fresh will introduce to you a source of sustainable agricultural by-products and interest. That is bagasse.

1. What is bagasse?

Bagasse is a remaining product after the production process. The physical characteristics are fiber, insoluble in water, and solvents. It is ivory white, light green, or purple, depending on the original characteristics of the cane. Besides, it contains some chemical components such as Cellulose, Hemicellulose, Lignin, and other solubilizers. Therefore, when it burns, producing CO2, SO2, N2… with high temperatures.

2. Sustainable properties of bagasse:

In the past, bagasse was harmless waste after the processing of the sugar industry. And not fully utilized, mainly used as fuel. However, with human creativity, bagasse has been applied and become valuable products for human life such as:

A) Environmentally friendly products

With its fast regeneration properties, the bagasse recycled process becomes environmentally friendly materials such as food cans, straws, cups, etc. With the ability to decompose quickly, it is easy to convert into soil humus for plants. Thereby, it helps to reduce plastic impacts on human health and the environment and improve the sustainability in production, in the conversion of waste into resources.

In addition, bagasse is also a non-woody material. Therefore, the use of bagasse instead of wood pulp will limit deforestation, and at the same time facilitate the reuse of agricultural wastes, without causing air pollution. Because for each ton of bagasse in the form of raw materials, it is possible to reduce the amount of wood usage by 0.5 – 0.8 m3.

B) Improve recirculation in production

• Green energy

Besides, bagasse is also a factor contributing to the implementation of green energy in production, typically the ability to convert it into electricity. Because it can generate thermal power. However, it does not cause the greenhouse effect and limits the exploitation of oil and fossil fuels.

Bagasse 1

The process of generating electricity from bagasse is not too complicated. Bagasse remaining after production will be put into boilers, to burn and generate steam. Then, steam pressure is put into the boiler to turn the turbine to generate electricity. Contributing to creating a potential biomass energy source to balance the power supply for hydropower in the dry season, the time of electricity production of sugar factories.

Bagasse 2

There are more than 40 million tons of sugarcane, equivalent to a generating capacity of 1,600MW, electricity from the bagasse will reach 4.7 million MWh, equivalent to 2.8 billion kWh of commercial electricity connecting to the national grid by 2030.

• Fertilizer production

Besides, in agriculture, bagasse makes fertilizer with very high levels of phosphorus, calcium, and sulfur in the composition, increasing nutrients needed by plants. However, dikes can create a clean, safe, and quality organic fertilizer for plants. We need to control several factors such as temperature, humidity, incubation time, etc.

Therefore, we can add the BioFix Composting product to limit the risks during incubation. With selected strains of microorganisms, it will promote the decomposition of the compost, and the decomposition of organic substances in the waste, improving the results of the composting capacitor. Moreover, it prevents the formation of bacteria in the compost that can be harmful to plants.

Through this, we can see that bagasse usage is correct, it will bring much value to human life and the environment.
