Slide 2

Overview Bioplastics terminology Bioplastics market trends Disposal Certification Conclusion

Slide 3

Traditional plastic Almost entirely derived from non- renewable, fossil sources These are artificial materials and nature does not know how to handle them

Slide 4

Problem is all around us! 4

Slide 5

What does plastic waste pollution look like? Coast of Dubrovnik/Croatia polluted by plastic materials discarded at sea, 2009

Slide 6

Recycling and energy efficiency - statistics

Slide 7

The term "bioplastics" refers to a biodegradable plastics and/or plastics derived from renewable resources (the definition from European Bioplastics) Interest in bio-materials has increased significantly due to concerns related to global climate change.

Slide 8

Bioplastic Source/base: renewable or not renewable Material: biodegradable or not biodegradable Plastics: 265 M tons (2010) Plastics Europe Bioplastics: 0.724 M tons biodegradable (non renewable resources) 428 000 t plastics from renewable resources 296 000 t

Slide 9

Development of bioplastics through history

Slide 10

Renewable sources - non- biodegradable Historically, plastic was made from renewable resources / there was no petrochemical industry 1869. nitrocellulose Hyatt billiard balls 1897. galalith first Zagrebs gramophone panel manufactured by Penkala Today : bio-polyethylene

Slide 11

What is biodegradable plastic? Biodegradation is degradation caused by biological activity, especially activity of the enzymes

Slide 12

Biodegradable plastics Considering the source/base we distinguish: natural polymers (PHA) modified natural polymers (viscose, methyl cellulose) synthetic polymers (PLA,polyesters)

Slide 13

What is compostable plastic? Compostable plastic is one that meets all scientifically recognized standards of compostabilty regardless of the origin of carbon. European norm is EN 13432, and USA norm is ASTM D6400

Slide 14

ASTM D6400 Main Factors 1. Mineralization 90 percent conversion to carbon dioxide, water and biomass through the action of microorganisms The same rate of degradation as other organic waste (ie. leaves, grass...) Time period of 180 days or less 2. Fragmentation Not more than 10% of the original dry weight of test material shall fail to pass through a 2 mm fraction sieve. 3. The impact on the environment No negative impact on flora and fauna

Slide 15

Biodegradable vs. compostable? Compostable plastic is a subset of biodegradable plastic that will decompose in the conditions and time frames during composting process Compostable plastic is always biodegradable Biodegradable plastic is not always compostable

Slide 16

What is bio-based plastic ? Can be natural polymer or synthetic plastic made from organic macromolecules that are derived from biological resources To be classified as a bio-based material it must be of organic origin and contain a certain percentage of new carbon derived from biological resources This definition is the base of ASTM D6866

Slide 17

U Comparison of plastic and steel manufacturing through history

Slide 18

Bioplastic market

Slide 19

Development of bioplastic market - main drivers Technical properties and functionality is selling High consumer acceptance (eco marketing) Organic recycling is a cost-efficient, new recycling option

Market share of bioplastics by application use in 2011.

Slide 22

World production capacity of bioplastics by material type in 2011

Slide 23

Production capacities of bioplastics in the world in 2011. and forecast by 2015.

Slide 24

Production capacities of bioplastics in the world by 2015.

Slide 25

Trendovi The share of bioplastics in the global plastics market will record substantial growth in the following years (planned annual growth of 44%)

Slide 26

Disposal

Slide 27

Methods of disposal after use of bioplastics

Slide 28

Ideal closed circle

Slide 29

Renewable raw materials for plastics. Organic Recycling (Composting) - new option. CO 2 Recycling - for climate protection.

Slide 30

Developing Global Legislation Around Biobased Plastics

Slide 31

Italy - first country in the world that banned the use of polyethylene bags (January 1,2011)

Slide 32

Certification

Slide 33

Proces of certification Variety of different materials What kind of criteria do we need? Certification as an instrument of market competition We have a defined system of certification for biodegradability and compostability of materials.

Slide 34

Certification Certification - procedure by which a third party gives written assurance that a product, process or service conforms to specified requirements (EN 45020:2006 standardization and related activities) Well-defined process in which a certification organization confirms the property of a plastic material, intermediate or product. Biodegradable plastics is not easy to distinguish from non- degradable plastics. Other ways of labelling are required in order for bioplastics to be used and disposed properly.

Slide 35

Slide 36

What Is Fueling The Growth of Bioplastics? Petroleum supplies are dwindling while demand for oil-based goods is rising For every 4 barrels of oil used, only 1 new barrel is discovered. Petrochemical-based plastics consume about 2.5 billion barrels of oil annually. Supplies will run short within the next 20 to 100 years.

Slide 37

Governments and consumers are demanding action to reduce dependence on oil. Increasing concerns over global warming, environmental pollution, toxic affects of some residual monomers and additives are driving legislation and consumer backlash against conventional plastics

Slide 38

More about the benefits of bioplastics.. Reduces dependence on fossil raw materials The concept of biorefinery-regional economy that has a source in bio-mass Programs of Corporate Social Resposibility (CSR) In the long run - economic perspective Conventional plastics will record high increase in prices (50-80% in 2 years) Bioplastics- enormous potential for savings

Slide 39

Not IfBut When It took 125 years to use the first trillion barrels of oil. Well use the next trillion in 30 years. So, why should you care? -Chevron Ad
