The aim of the current research is to find sustainable pellet resources that are not made
from forestry, agricultural materials, or food products. Evaluation has been carried out by
experimentally determining the biofuel parameters of two invasive plant sp
ecies. In comparison
to the process of finding a new application, their use in the production of solid biofuel pellets
would not require additional investment for the construction of a new pellet production plant. The
article’s hypothesis suggests that bio
fuel parameters for invasive plant species are sufficient for
the production of solid biofuel and that their properties can be improved by binders that are
available wor
ldwide in the form of residues.
The experiment was carried out for two invasive plant s
pecies that are widespread in Latvia
–
Heracleum sosnowskyi
Manden and
Solidago canadensis
L
.
The binders used include potato peel
waste and spent coffee grounds. All of the tests have been carried out
according to ISO standards
on biofuel testing. Results show that
H sosnowskyi
is more suitable for solid biofuel than
S
canadensis
as it has a higher calorific value and an ash content that is two times lower
–
3wt%.
Coffee grounds are a suitable binder b
ecause they increase calorific value.
The type and amount of binders partly confirms the hypothesis, since both binders reduced the
amount of ash in pellets. Further research is needed to carry out pellet durability tests. It is also
necessary to carry out
an economic analysis in order to evaluate how beneficial it may be to use
H sosnowskyi
as a solid fuel in existing pellet production plants, thereby avoiding large initial
investments and not encouraging the cultiva
tion of invasive plant species.
