Analysis of Tropical Fruit Waste Biomass Generation in Indonesia and Its Reuse Potential

Abstract

Several The following research focuses on analysing waste biomass generated thru the processing of specific tropical fruits, such as Dragon fruit, Duku, Mangosteen, and Snake fruit. The amount (in %) of produced fruit waste biomass (skin, peel) during fruit processing was monitored, and collected waste biomass was subjected to determination of its basic chemical parameters and elementary composition within its possible utilization as a source of renewable energy. Averaged determined ratio of generated waste biomass of total fruit mass was following: Dragon fruit -35.83%, Duku -23.48%, Mangosteen -69.40% and Snake fruit -15.16%.Analysis of moisture content Mc(%) exhibited unwanted high values of such indicator (44.57 -61.70%), but satisfactory level of ash content Ac(1.15 -8.23%), which indicated suitability for combustion purposes. ObservedMc results may be improved byusing solar renewable energy. Elementary composition analysis proved a suitable ratio of C:N (±25-30:1) in the case of Dragon fruit and Duku fruit samples, which indicated their suitability as a natural fertilizer in the form of the compost.In conclusion, investigated specific fruit waste biomass contributes to the waste production in a significant way. Therefore, their sustainable utilization is necessary and due to the observed data also advantageous (possible highly advanced source of green energy purposes.

Performance of the silica adsorbent from snake fruit peel for removing heavy metals of Ag, Cu, Mn, and Cr in SCW

“…The management and utilization of SFPW is one of the interesting topics because apart from being able to reduce negative impacts on the environment, this effort also has added value from the waste. The SFPW contains 72.45% carbon components [3], and silicon dioxide (silica, SiO2) which is quite high, namely around 65-69% [4], so it has the potential to be used as a raw material to produce SiO2 adsorbents [5] or SiO2 adsorbent. As reported in several research results.…”
