Abstract
Brazil's abundant biodiversity and favorable climate make it a world leader in the use of biomass for energy and biomaterials. Green coconut, a highly produced commodity on Brazil's coast, holds immense potential for bio-product generation from agro-industrial residues. Thermochemical conversion processes like pyrolysis offer an eco-friendly means to harness this biomass. In this study, coconut waste was deposited in soil, left exposed to environmental factors for 120 days, and periodically subjected to pyrolysis. Raw coconut fibers and fibers from the deposited biomass underwent pyrolysis to produce bio-oil. The phenolic compounds in the bio-oils were quantified through external calibration, with the analysis conducted by GC/qTOFMS. This is the first study to demonstrate that bio-oils derived from deposition biomass, simulating landfills, exhibit increased concentrations of phenolic compounds compared to the natural state. This highlights innovation in bio-oil production and its environmental significance by transforming discarded waste into valuable resources, suggesting their utility in polymer, pharmaceutical industries, or energy production.
