Potential plastic digestor of Euphorbia Tirucalli

Abstract

Natural products that cause oxidative stress and even local corrosion are of interest as degrading products of materials persistent in nature, such as plastic. This chapter evaluated the corrosive and shrinkage physicochemical action of total aqueous extracts of Euphorbia tirucalli, a species described as corrosive and shrinkage, from specimens with geographic variations (mangrove and mountains of Rio de Janeiro and the north coast of São Paulo) also subjected to temperature variations, on polypropylene (PP-5). This plastic is used on a daily basis and can be subjected to reuse processes. In the present experiment, aqueous extracts were prepared from temperature variations and their plant chemical productions were marked using high-performance liquid chromatography associated with the UV detection spectrum. Unlike previous tests, none of the extracts were capable of immediate extraction or digestion over 30 days. Only for the stems from Petrópolis (50%) and the north coast of São Paulo (33%) subjected to boiling was the activation of their gummy action observed, acting as glue on the PP-5. suggestive of natural polymerization for cellulose. Despite the observations regarding the potential practical, useful and cheap application of this test, it was evident that the raw latexes from the geographical regions tested at different temperatures were not capable of chemically digesting isopropylene, thus suggesting that the enzyme capable of digesting this plastic effectively participates when the endophytic fungus present in this species finds favorable conditions to develop as previously discussed. Phytopathology tests confirmed the biological effects verified through the roots of E. tirucalli and subsequently, new cultivars developed followed the variation in the release of cyanuric acid into the test environment, marking interest since cyanuric acid can play a role in recovery soil, in addition to being a herbicide, insecticide and being able to reduce contamination by gram-negative fecal coliforms in water, especially Escherichia coli. Based on this contribution, new tests will be carried out in order to investigate mechanisms of action in phytoremediation, comparing them with those already preliminarily evidenced and communicated. A specific protocol has been developed in Plant Biotechnology, as these jobs have the possibility of useful and profitable application in reuse, to be carried out by small solid waste recyclers. It will also aim at autonomy for ethnic groups in urban situations, as well as promoting environmental sustainability.
