Abstract:

Mango production in Colombia reached about 260.000 tonnes per year by 2018, and about 25% to 40% of the raw material is left as a residue. Several companies produce pulp and dehydrated fruits; leaving peels, husks, and seeds as raw material for new products. For that reason, Mango Fruit Waste (MFW) present as an attractive alternative to design biorefineries that provide biocompounds to use in everyday products and biomass to produce bioenergy. The compositional analysis of theseresidues provides a list of compounds or “fractions” that could be retrieved. In this study, pectin was removed through chemical and enzymatic treatment, extractives were retrieved using Soxhlet extraction, and mango seed oil was recuperated using supercritical CO2 extraction with conditions that maximized extraction yield. Then, the Biological Methane Potential (BMP) of mango waste were evaluated using a modified version of the VDI4630 protocol, in order to determine the influence of the removal of biocompounds in anaerobic digestion.From that, best conditions of methane production were 444 ± 3.6 mLCH4/gVS for mango peel, 749 ± 8.5 mLCH4/gVS for mango seed without oil and 529 ± 8.4 mLCH4/gVS for mango husk.Results demonstrate that an energy-driven biorefinery would be the best option taking into account that mango residues could be digested obtaining high methane production rates, providing at the same timeoiland pectin that could be used in everyday products.A biorefinery using mango waste could be a sustainable and viable option for producing countries due to the wide range of compounds that could replace raw materials who in another way would be obtained from non-renewable resources.
