PET-Bottles: Before recycling - X-mas-cycle them

PET-Christmas tree in Auckland, New Zealand, 2013
Last year in December when I was visiting New Zealand we stopped by in Auckland. While crossing one of the squares, I immediately noticed from far away green and white triangles of different sizes standing there in a strange configuration. People in New Zealand were also in Christmas mood. These triangles were PET bottles of 0.5 up to 1.5 liters assembled creatively together to form multiple Christmas trees of different sizes and showing variable patterns.

This represents a way to show Christmas elements in a simple, creative and modern way. After the holidays, the bottles will be again collected and recycled to fibers for several applications.
So, when you like such applications and you have not yet a Christmas tree you can give it a try.



Other Christmas decorations involving polymers are for example polystyrene based Christmas stars:

Fill polystyrene granules in a backing shape and put them for 5 minutes in the oven. The granules will get soft and glue together. After they cool down, you can remove the shape and you will obtain a transparent star mimicking snow. You can also produce other shapes by the same method to decorate your house and/or Christmas tree.




I wish you a Merry Christmas and all the best for 2015!

Our plastics consumption - A view by polymer type, region and process


A polymer engineer friend of mine gave me a good suggestion for a topic for this blog:
My colleague provided me the report of AMI Consulting 2014 and its data and facts from it that I will now share with you:

For you to get a feeling what the global polymer industry consumes on raw materials: It is worth more than US$ 500 billion per year. The industry subsequently transforms these into polymer based products which have a value of more than US $ 1 trillion. This is indeed a major driver of our world economy!

Everyone of you utilizes or at least touches in average 50 polymer based items per day.  Polymers provide these products the targeted performance and functionality.

But why are polymer products so successful?

Polymer based materials can be easily designed by chemically means as well as easily processed for particular ends. They can be made tough or flexible, hydrophobic or hydrophilic, and by processing they can take variable useful shapes that you may find all around your car, or your kitchen.
Therefore, the replacement of metals, glass and paper was inevitable.

Let’s have a look at the world demand grow: Since the year 1983 the demand grows from 45 million tonnes to an expected market demand of 250 million tonnes for 2014. Interesting is the shift of demand in a regional point of view. In 1983 areas like North America, Western Europe and Japan kept a share of world demand of 74%. Looking back to 2013, their world share decreased to 32% and countries like China and East Asia increased from 6% up to 29%. 

What about future trends?

A strong grow in demand is expected in the Indian sub continent. Why? The population there is bigger than in China but it has a polymer demand that is currently one-fifth of the size.

In Europe, the regions are expected to have the slowest growth rates. However, it has shown a constant market demand of 44-45 million tonnes for the past 3 years.

The market outlook for North America is better due to the availability of gas feedstock, which is necessary for producing polymers. It is predicted a cost reduction, especially for polyolefins. 

Which industry needs polymers the most?

AMI also had a look at the end-user applications of polymers: Although in many areas used, the field of packaging got dominant (50% of demand) and this in all parts of the world. It is followed by applications for construction (20% of demand). Applications like automotive, medical and electrical have a high attention, but in the volume they have a relatively small part.

According to a AMI calculations, there are over 230,000 plastics processing operations worldwide - this is an impressive number too!
And within the polymer processors one can find 130,000 injection moulding companies worldwide.
