(TVU) – An innovative idea that has just won the first prize of the “Green Creative Ideas” contest in Tra Vinh province in 2021 designed by Le Thi Thuy Duy, a student of the University of General Business Administration course 2018.
Ms. Thuy Duy said that the idea uses the available material in daily life, that of sugarcane bagasse, to find a solution to help protect human health and be environmentally friendly. After taking all the sugarcane water, we use this bagasse to create activated carbon masks. They can replace the difficult-to-decompose medical kind of mask that has a high price.
The activated carbon masks made from bagasse are environmentally friendly and easily degradable in the natural environment. Besides, this mask type can filter droplets containing a virus of little more than 100 nanometers. The mask makes it easy to breathe and not itchy, useful for those who have to wear masks for a long time or have underlying respiratory diseases.
The new material containing Nano Cellulose fibers can be biodegradable, suitable for the single-use feature of the mask. The production of this fiber requires relatively simple equipment and can be quickly produced in large quantities and at a relatively low cost. Because sugarcane bagasse is a waste product, they are easy to find and buy at a relatively low cost.
Thuy Duy said that “Activated carbon masks made from sugarcane bagasse solves the problem of environmental pollution and decomposes into organic matter for plants. Bring an environmentally friendly product and protect human health during the epidemic season. Contribute to creating jobs for workers in the production”.
Moreover, this kind of mask from available natural materials does not carry any harmful substances, ensuring environmental friendliness and safety for users.
In addition, mask products from sugarcane bagasse can decompose in the natural environment after about 30-60 days, creating organic substances that nourish plants.
The first step of producing masks is to collect sugarcane bagasse. Bagasse after collection is dried, cleaned, then boiled with boiling water at a temperature of 100 degrees Celsius and then pureed into starch. This component is further laminated and dried. The resulting product is a thin, odorless, old yellow material sheet.
Bleach the sheet of material with lemon juice and vinegar mixed with warm water. Shape and process the layers of the mask. Then pack the product and put it into use.
