Abstract

This study had the objective of developing a product having as raw material the residual parts of lettuce, which are its roots and residual leaves. To this effect, a thought experiment was performed in order to create a flame-retardant cellulose film using a green-sourced, vegan, and biodegradable raw material. This product was designed with the goal of protecting furniture, however, the product could also be effectively applied in paintings and other cellulose-based materials. A production line was proposed, and through economic analysis, it was determined that the manufacture of this product is profitable, with a production price of 2.15 per unit (m2) and a retail price of 6 per unit (m2). This flame-retardant film is unique compared to the others on the market, which are mainly plastic-based, since it is developed from a biodegradable material, making it a sustainable option for a zero-carbon economy. This film has a fire delay of approximately 4.5 minutes when exposed to fire.
