certain. So, a code is present and that should be followed during the assessment to
minimize the impact of the possible limitations. The code helps in conducting an
impactful LCA. What are the code of conduct and the limitations and the ways it
affects the study will be discussed in the further sections?
Data Quality: The quality of data involved in the study plays an important role
in decision management by organizations. The data provided should not be kept
on an as-received basis. A comparative study of the product with other products is
necessary. The credibility of the study cannot be trusted if the assessment is done
with the provided data from the manufacturers. Manipulation of data is possible and
hence it must be validated with the secondary data, literary data, previous studies,
and standardized data sets.
Life cycle boundaries: The system boundaries must be considered on its versatility
basis. Not all the process boundaries can be tested and validated. Some processes do
not synchronize with the assessment.
Country-specific technology types: The standard inventory articles are usually not
applicable everywhere for conventional energy and renewable applications. The
applicability of the processes and the incorporated technologies behave differently.
So, the study and inventory management must be country specific.
Evaluation stage priorities: While comparing two products or processes, if the
assessment depicts a similar kind of impact and the two systems are acquiring certain
advantages over another. The ethical and rational decision is mandatory. Considering
the present study, biomass replacement in metallurgical sintering is resulting in a positive reduction in carbon footprints and cost of the process but the technical feasibility
is at stake. On the other hand, coal provides excellent technological feasibility but its
emission generation behavior is not acceptable. So, a rational decision of combining
both the fuels for technical feasibility and environmental acceptability can be a positive outcome and should be assessed further. The code is important because it speaks
about the priority-based evaluation of the system.
Definition: Defining the system, the boundaries, the concerned objects, and the
purpose must be clearly stated. Questions such as (a) why LCA is performed for
the system, (b) how it will respond to the general structure, (c) how it will affect the
user, and (d) how extensive are the study and the inventory involved. Without the
understanding of these statements, An LCA will seem to be a directionless study.
Delimitation of the system under study: Once the definition is identified with a clear
understanding, the system boundaries must be created carefully. System boundaries
must be specific. A system under assessment can have numerous possible aspects, if
the specific functionality is focused then the boundaries must be specific too.
Inventory: An inventory is the data set that provides the standard and the experimental data to assess the system. But the inventory must be answerable to certain
questions such as (a) does the data includes all the process, (b) whether the data are
collected from each stage or for a specific part, (c) the origin of the data source, (d)
