Análise do ciclo de vida de biocompósitos de bagaço em substituição ao poliestireno expandido em embalagens de delivery
Resumo
The delivery market has grown a lot in recent years, accelerated by the restrictions of
the COVID-19 pandemic, this style of eating has become a necessity in many people's lives.
However, delivery market is still based on the use of packaging made of plastic. These
packaging, when discarded incorrectly, can turn into microplastic and end up in the organism
of marine animals and even humans. It is in this scenario that studies are emerging to find
more sustainable packaging, one of the many possibilities is packaging made from bagasse,
which in addition to using a by-product of the sugar and alcohol industry is also
biodegradable. This work aims to analyze the life cycle of 1kg of delivery packaging made
from two different materials: bagasse and expanded polystyrene (EPS). To calculate the
impacts of each chain, the OpenLCA software was used. For the bagasse packaging
production flow, it was considered that the raw material would come from a sugar and alcohol
industry, subsequently going through a pulp treatment process, heading to the thermoforming
industry to generate the packaging and finally having two disposal possibilities: landfill or
composting. For EPS packaging, the process begins with the removal of oil, cracking of
Naphtha, polymerization and expansion of polystyrene, followed by the thermoforming
process and disposal in the landfill. As a result, bagasse performed worse in 7 of the 11
categories studied, with sugarcane cultivation being the main responsible for the values
achieved. In relation to disposal in landfill or composting, the impact categories had very
similar values to each other, not making the advantage of biodegradable packaging evident.
