22. COMPARISON OF METHODS
CONFIDENTIAL | RESTRICTED OPERATIONAL | INTERNAL USE | PUBLIC
Difference between disposable and reusable single score index. (negative
values in favor of reusable and positive values in favor of disposable)
 New method was deployed throughout all LCA projects as an update to the market best practices. The main
updates rely on:
 Number of impact categories: from 12 to 15
Mainly include human toxicity categories to the single score index and split abiotic depletion into two
categories, namely fossil fuel depletion and Mineral depletion.
 Characterization factors and risk assessment concept
Water depletion category was updated to a water scarcity model. It enhances the assertiveness of the
results by providing a nation level result based on the pressure on water resources.
 Normalization factors
Updated accordingly to the impact category and data availability
 Weighting factors
Updated considering survey with 104 people inside and outside Braskem. For this study, it is important
to note that water category weighting factor dropped from 9% relevance to 5% relevance.

Difference between disposable and reusable single score index. (negative
values in favor of reusable and positive values in favor of disposable)
 Study’s update was commissioned to include paper amongst the disposable options, update data on washing
machinery and update the results according to the new method. The main updates rely on:
 New washing machine considered
The original study considered a conventional washing machine (household) in which 60 cups could
be washed per cycle. The update considered a cups only machine (professional use) which washed
31 cups per cycle and uses 73% less energy and 78% less water per cup.

24. COMPARISON OF METHODS
CONFIDENTIAL | RESTRICTED OPERATIONAL | INTERNAL USE | PUBLIC
The method called AWARE (Available WAter REmaining) consolidated for the Water Footprint
(Boulay et al., 2015), with differentiating factors by watershed, is the result of a consensus work
promoted by the United Nations Development Program (UNEP) and Society of Environmental
Toxicology and Chemistry (SETAC), in the Life Cycle Initiative, for the category of water scarcity.
ReCiPe method
2015 LCA
AWARE method
(Available Water Remaining)
2019 LCA update
The ReCiPe method is a continuation of the Eco-indicator 99 and CML 2000 methods that integrate
and harmonize the midpoint and endpoint approaches in a common and consistent structure. This
method has a global application scope for the categories of impact on climate change, ozone
depletion and resource consumption and the scope of application valid for Europe for the other
impact categories.

25. COMPARISON OF RESULTS

26. CONCLUSION
• In the baseline scenario, considering the single score, the reusable alternatives has lowest
potential environmental impact, compared to disposal alternatives. Even considering a
scenario where the disposable PP cup is 100% sent to recycling, the reusable alternatives
maintain the best environmental performance.
• Considering the scenario with regular washing machine, the results are close to being
inconclusive with slight advantage to reusable alternatives.
• In the scenario with manual washing the reusable alternatives maintain the best
environmental performance.
• For the disposable alternatives the main impacts are concentrated in Raw Material and
Final Disposal stages. For the Reusable alternatives the impacts are concentrated in Use
stage.
