AGENDA

Braskem: quick introduction

Case studies in Green chemistry

Renewables and atom economy

Innovative catalyst

CASE STUDY – NEW GRADES OF I’m green™ POLYETHYLENE

Polymer plant improvements

Richer product portfolio

• internal development + vendor technology• pilot scale testing• industrial scale validation• scale‐up of catalyst production

• optimal processing conditions• energy integration

• new grades with existing cliente demand• high performance PE

CASE STUDY – NEW GRADE OF I’m green™ POLYETHYLENE

THE 12 PRINCIPLES OF GREEN CHEMISTRY

1 Prevention

2 Atom economy

3 Less hazardous chemical synthesis

4 Designing safer chemicals

5 Safer solventes and auxiliaries

6 Design for energy efficiency

7 Use of renewable feedstocks

8 Reduce derivatives

9 Catalysis

10 Design for degradation NOT APPLICABLE

11 Real‐time analysis for pollution prevention

12 Inherent safer chemistry for accident prevention

• less hydrogenation, better co‐monomer incorporation• less impurities, less purge

• raw materials are flammable

• PE is safe and non‐toxic

• no solventes are used

• no major changes to already eficiente plant• I’m green™ PE is made from renewable ethylene• new grades = more throughput

• no derivatives, straightforward reactions

• no derivatives, straightforward reactions

• recyclable product, circular economy

• online instrumentation and analyzers

• PE is safe and non‐toxic• raw materials are flammable

• all atoms used in polymerization

Preliminary, qualitative assessment intended only as input for an external evaluation which is still in progress

OTHER CASE STUDIES

1. PreventionPrevent waste rather than treat or clean up waste

2. Atom EconomyMaximize incorporation of all materials into the final product.

3. Less Hazardous Chemical Syntheses

4. Designing Safer Chemicals 5. Safer Solvents and AuxiliariesAvoid auxiliary substances (e.g., solvents, separation agents, etc.)

6. Design for Energy EfficiencyIf possible, at ambient temperature and pressure

7. Use of Renewable Feedstocks 8. Reduce DerivativesAvoid unnecessary derivatization

9. Catalysis 10. Design for DegradationChemical products should be designed not to persist in the environment.
