Abstrakt
Energy consumption in Indonesia and Vietnam has grown rapidly in recent decades.
To meet the energy needs of both countries, a higher utilisation of waste biomass sources may
represent an adequate solution. Investigated samples represent major crop residues (waste
biomass) originating mainly from the agriculture sector of the selected countries. Herbaceous
waste biomass from Indonesia is, namely, cassava stems and root peelings
(
Manihot esculenta
),
coffee leaves (
Coffea arabica
), cacao leaves (
Theobroma cacao
), banana leaves (
Musa
acuminata
), bamboo leaves (
Bambusoideae
spp.) and aloe vera leaves (
Aloe vera
). Furthermore,
fruit and aquatic waste biomass originating from Vietnam
is, specifically, sugarcane bagasse
(
Saccharum officinarum
), durian peelings (
Durio zibethinus
), rambutan peelings (
Nephelium
lappaceum
), banana peelings (
Musa acuminata
), water milfoil (
Myriophyllum spicatum
) and
water hyacinth (
Eichhornia crassipes
). All
mentioned types of waste biomass were subjected to
proximate and calorimetric analysis: moisture, ash and volatile matter contents (%) and higher
and lower heating values (MJ
kg
–
1
). Obtained values indicated the highest level of ash content in
fruit bioma
ss samples in the case of sugarcane bagasse (0.84%), in herbaceous biomass in the
case of cassava stems (3.14%) and in aquatic biomass in the case of water hyacinth (14.16%).
The highest levels of lower heating values were achieved by following samples (be
st samples
from each biomass type): cassava stems (17.5
MJ
kg
–
1
); banana peelings (17.3
MJ
kg
–
1
) and
water hyacinth (12.8
MJ
kg
–
1
). The overall evaluation of all observed samples indicated that the
best suitability for energy utilisation by direct combusti
on of investigated representatives is fruit
waste biomass, followed by herbaceous waste biomass
and then aquatic waste biomass.
