Briquetting - Adding value to cotton waste
Cotton is a natural fiber, widely cultivated and present in the fabric. The processing of cotton, as well as that of several other types of crops, generates a volume of vegetable residues. However, especially in more recent times, it has become a necessity to properly dispose of this waste.
Just discarding in-natura waste ends up being costly and a waste of raw material that could be better used. It is necessary to think about good social practices, adapting sustainable solutions in the processing and disposal of waste.
An effective solution for the treatment of cotton waste is compaction.
The process for this is briquetting. Both the cotton peel and the cotton seed can be briquetted. The briquetting process compresses the waste through pressure and temperature, thus intertwining the vegetable fibers with the release of natural lignin, thus transforming the bulky raw material into a high density briquette. In fact, briquettes have several applications, however, they stand out as a substitute for firewood and can be used as fuel in furnaces.
Its density reduces transport costs. In the case of disposal, it is environmentally friendly and can be inserted back into the soil. It is economically viable as it is sold as feed or fuel.
Usage and Results Impressions
Advantages of compacting waste into briquettes:
• Reduction of transportation costs;
• Dirt reduction;
• Fire risk reduction;
• Volume reduction;
• It is environmentally friendly;
• Can be inserted back into the soil;
• Can be used as fuel in furnaces;
The cotton briquetting has several benefits, allowing the cotton residues to be used both for their own use, when the farmer also works in areas where the use of fuels in furnaces and boilers is necessary, as well as it can also be used with a source income by providing this fuel to several companies.
This reuse makes the need for the correct disposal of cotton waste profitable.
Lippel has a range of briquetting equipment, from small to large, with a production of up to 2,200 kg/h per unit, to meet the need to reuse various types of plant residues such as wood biomass, cotton, rice, and many others.
