LIFE CYCLE APPROACH

The life cycle approach sets the foundation for Braskem’s purpose & belief.

01 LIFE CYCLE APPROACH

LCA

Life Cycle Assessment

LCA is a complete analysis of the ENVIRONMENTAL IMPACTS of a product ´ s life cycle , from extraction of raw materials to its final disposal

With this knowledge , Braskem can make better decisions towards more sustainable actions

01 LIFE CYCLE APPROACH

WHY LCA?

LCA is the most recommended tool to analyze the environmental impacts along the WHOLE VALUE CHAIN , considering the life cycle

Allows for DATA DRIVEN & SCIENCE BASED decisions

Leva em conta um conjunto amplo de IMPACTOS AMBIENTAIS.

Reinforces TRANSPARENCY by disclosing our environmental impacts, following international standards and stakeholder demand

Is a key driver for new solutions and strategies to leverage SUSTAINABLE DEVELOPMENT

01 LIFE CYCLE THINKING AT BRASKEM

SUSTAINABLE DEVELOPMENT STRATEGY

Braskem’s Sustainable Development Strategy must be fully integrated into the strategy of its business and implemented through it, aiming at continuously strengthening its purpose of “improving people’s lives by creating sustainable solutions through chemicals and plastics plastics

METHODOLOGY

LCA studies follow the ISO 14040/44 standards and consider the environmental impacts of 16 categories.

02 METHODOLOGY

ENVIRONMENTAL IMPACTS EVALUATED

• Climate Change
• Ozone Depletion
• Respiratory Inorganics
• Photochemical Oxidation
• Acidification
• Water Use
• Land use
• Mineral Depletion
• Freshwater Eutrophication
• Fossil Fuel Depletion
• Toxicity - humans and ecossystems
• Freshwater Ecotoxicity
• Marine Eutrophication

* Result from broad assessment with interested parts

LCA RESULTS: MATTRESS

Following Braskem´ssustainability approach, this is the Life Cycle Assessment study for the environmental profile for mattress. 

 

The project compares the performaceof expanded Polyethylene (PE) to replace Polyurethane (PU). 

 

The study was revised by KPMG.

03 MATTRESS

CONTEXT

Innovak uses a unique and inovative solution that allows for the expanison of polyethylene (PE) to be used in matress filling This is an alternative to partially substitute expanded polyurethane (PU) currently used in matresses ZeeFlex

ZeeFlex solution

• Mass reduction around 8% of total mattress •
• Substitution of 60% of the PU foam with expanded PE
• • Allows for recycling of the PE foam in end of life

Objective

Compare the use of expanded polyethylene (PE) in matress filling to the conventional alternative with expanded polyurethane (

SENSITIVITY ANALYSIS

Faced with various insights that emerged throughout the process, some scenarios of sensitivity were made about the mattress life cycle.

04 SENSITIVITY ANALYSIS

The sensitivity analysis performed were:

• End of life scenarios, considering landfill and recycling of the mattress’ components
• Reuse of the springs
• Substitution of the fossil PE by the renewable alternative (I’m Green™ PE from Braskem)
• Durability of the mattress (usage years lifespan)

04 SENSITIVITY ANALYSIS

END OF LIFE: RECYCLING X LANDFILL results for 1m 2 of mattress

04 SENSITIVITY ANALYSIS

END OF LIFE: RECYCLING X LANDFILL results for 1m 2 of mattress

Analyzing the possible recycling scenarios, we learned that:

• The best scenario is achieved when 100% of the steel (springs) and 100% of the PE foam are recycled , resulting in a 36% reduction when compared to the conventional mattress
• If steel (springs) and PE foam are recycled , the environmental impact from the ZeeFlex mattress can be reduced in additional 25%
• The PU foam has a lower recovery potential , usually used in downcycling processes (used as pillow filling or carpets after recycling
• For the conventional mattress , if steel (springs) are recycled , the environmental impact can be reduced in 18%

04 SENSITIVITY ANALYSIS

SPRINGS REUSE (results for 1m 2 of mattress

In addition to the recycling of expanded PE and steel, some of the springs can be reused , resulting in greater environmental gains.

SUBSTITUTION OF PE: FOSSIL X GREEN

MATTRESS USAGE AND DURABILITY

• By increasing the durability in 2 years , impacts can be reduced in 20
• By reducing the durability in 2 years, impacts can increase 25%

CONCLUSIONS

LIFE CYCLE ASSESSMENT OF THE MATTRESS

After comparing the environmental performance of ZeeFlex mattress with conventional mattresses, we can conclude that:

• ZeeFlex mattress has 12% less environmental impacts than the conventional ones, achieved mainly from the mass reduction and from the partial substitution of the PU foam by expanded PE foam
• Lower impacts from logistics and transportation
• Lower impacts from the production of PE foam

• The main alternatives for reducing the environmental impacts of the ZeeFlex mattress are: •
• Recycling of PE foam when mattress is discarded
• Final destination with reuse of springs and/or recycling of residual steel (that can not be reused)
• Increase in the use of expanded PE in the mattress composition, replacing a larger amount of PU
• Substitution of fossil PE by Braskem’s I'm green™ Polyethylene
• Capture of buthane gas in the PE expansion process
• Extending mattress’ lifespan
