The generation of waste from plastic wrappers used in products packaging of various types and activities progressively constitutes a problem of environmental contamination due to their nature of being non-biodegradable. Faced with this reality, a research was carried out that aimed to produce paper with ecological characteristics by taking advantage of the crown, which is one of the non-consumable parts of the Ananas comosus (pineapple) fruit, that becomes part of the organic waste that is discarded with the consequent cost for its disposal. In the process, 5 kg of Ananas comosus crown was used, testing three processes, the first: Ananas comosus crown pulp, Second: Ananas comosus crown bleached with NaClO, and third: Ananas comosus cocrone pulp bleached with H2O2. A yield of 26.6% of production of ecological paper was obtained with characteristics of grammage between 73.66 and 86.18 g/m2, thickness of 113 to 116 μm, whiteness of 22 to 59.2% photovlt, Resistance (tension 5760.2m, humidity between 7.84 to 9.18 %, cobb 164.7 to 424 g H2O/m2 and tear resistance between 9.96 to 13.16 mN-m2/g). The use and recovery of waste converted into paper for later use is an objective achieved within the concept of circular economy.
