Bagasse Material Meaning


Bagasse material meaning: Reasonable development and utilization are of great significance for protecting the environment and promoting sustainable development of agriculture. Bagasse is one of the largest agricultural wastes in the world, and the preparation of environmentally friendly materials is one of the important ways of high-value utilization of bagasse raw material.


Bagasse Material Meaning - Why Use Bagasse Raw Materials?

With the development of modern agriculture, environmental pollution and resource waste caused by the accumulation of large amounts of agricultural waste have become increasingly prominent. Vigorously developing the comprehensive utilization of agricultural waste is of great significance for protecting the ecological environment and promoting sustainable agricultural development. Sugarcane bagasse raw material is the residue of sugarcane stalk fibers after sugarcane is crushed and pressed to extract sugarcane juice, and its content accounts for 24% to 27% of sugarcane. As the third largest sugarcane growing country in the world, China's annual output of bagasse reaches more than 20 million tons. Compared with other agricultural wastes, bagasse raw material also has the characteristics of concentrated sources, simple collection, small transportation radius, relatively stable composition, and uniform properties. Therefore, the development and utilization of bagasse resources has received extensive attention from researchers at home and abroad. People gradually realized the bagasse material meaning.

Due to the high degree of lignification of bagasse and the lack of traditional conversion and utilization methods, its traditional utilization method is limited to extensive and inefficient utilization as boiler fuel combustion and power generation, and the utilization rate is extremely low, most of the bagasse raw material is directly discarded Or landfill treatment. In recent years, with the continuous development of modern biomass conversion and utilization technologies, the use of bagasse has become increasingly diverse. At present, domestic and foreign research mainly focuses on energy, feed, matrix and materialization. Among them, materialization is one of the important ways of high-value utilization of bagasse raw material, and the development prospect is broad. This article briefly summarizes the research progress of bagasse materialization in recent years, and derives the bagasse material meaning. On this basis, it looks forward to the development direction of high-value and comprehensive utilization of bagasse.


Research Progress Of Bagasse Material Meaning

The chemical composition of bagasse is mainly lignocellulosic, in dry matter cellulose accounts for 32% to 48%, hemicellulose accounts for 19% to 24%, lignin accounts for 23% to 32%, and ash content is about 4% . The chemical composition of bagasse makes it an ideal raw material for the development of environmentally friendly materials.


Bagasse Raw Material Has Many Usage Meaning Like Below:

1. Pulp and paper production and production of environmentally friendly tableware

2. Production of artificial board

3. Preparation of microcrystalline cellulose

4. Development of lignin-based phenolic resin adhesive

5. Preparation of regenerated cellulose membrane

6. Preparation of polyurethane materials

7. As a composite reinforcing agent

8. Preparation of nanocellulose


Greenweimo Understands The Bagasse Material Meaning

Greenweimo uses bagasse to produce pulp and paper and environmentally friendly tableware. Bagasse can be used in the production of household paper and newsprint, such as toilet paper, napkins, packaging paper, corrugated paper, coated paper, copy paper and double offset paper.

As early as 1926, the state of Louisiana in the United States has begun to use pulp from bagasse to make paperboard. In addition to the United States, Argentina, Colombia, Mexico, India, Australia and China also use bagasse raw material to make pulp and paper. In China, pulping and paper making are the most important ways of using bagasse besides fuel. However, due to geographical and raw material restrictions, it is mainly concentrated in areas where sugar enterprises are concentrated, such as Guangxi and Yunnan. According to reports, the production capacity of bagasse pulp and bagasse fiber paper in Guangxi has reached 700,000 and 500,000 t / a, respectively.

In the industrial production, bagasse pulping is mainly based on the alkali method, but it has serious environmental pollution. This goes against the bagasse material meaning. Therefore, Heiningen and others proposed the idea of bagasse pulping and paper making combined with biological refining, that is, not only to obtain pulp, but also to obtain high value-added chemicals, such as ethanol pulping, acetic acid pulping, and high boiling alcohol pulping. Pulp and the like have the advantages of solvent recovery, and can simultaneously separate hemicellulose, cellulose and highly reactive lignin.

After bagasse pulping, it can be molded into disposable green environmental protection tableware. This meal has sufficient strength, and is resistant to oil, hot water, non-toxic, tasteless, pollution-free, biodegradable, and can completely replace plastic tableware. " White pollution". The use of bagasse to produce green and environmentally friendly tableware began in the 1990s. Qiu Renhui et al. Developed an automatic production line for bagasse chemical pulp molded tableware, and optimized the molding process parameters suitable for this line. According to reports, there are nearly 20 companies that use bagasse raw material to produce green and environmentally friendly tableware. In addition to supplying the domestic market, the products are also exported to Japan, South Korea, the United States and Spain.


In summary, bagasse as a good green renewable polymer material is increasingly valued by people. People gradually understand the bagasse material meaning and its comprehensive utilization methods are becoming more and more diverse. However, at present, only a few extensive utilization methods such as pulp and paper, green environment-friendly tableware and wood-based panels have achieved large-scale production. The high-value utilization technology of bagasse and green production technology have yet to be developed.
