Comparison to the start of the project

As a team, we were able to gain a lot of experience. There were also some problems that we were able to solve together.

We sat down together and compiled all the experiences and information and put them in order. We also designed an information flyer to give people who don't know log cabins an idea.

We are still working on other aspects and comparisons with the beginning, so that we can see how well we have progressed.

Step 1 - Vision & Imagination

Before the experience of the heart project

Through the topic "log cabins", people are encouraged to think. The results of the survey will be very varied, as everyone has their own idea of what a home should be.

But this makes it exciting and we can let the different views be reflected and then think about which aspect we find best.

The contact with Canada brings us closer to the people who invented this "project" of log cabins and are already living it.

We can also learn more about the construction, as we have a contact in Switzerland. It is a company that builds such log cabins here in Switzerland.

Rare Earth Elements

(Alexandra Eberle & Cheyenne Lea Henzelmann)

Rare earth elements

Rare earth = 17 metals --> same chemical properties:

  • reactive
  • soft
  • silvery

physical properties --> very different
e.g. react magnetically under UV light.

Occur in many places in the earth's crust. Minerals monazite & bastnäsite contain several SEM occurrences above 1% --> rare, therefore "Rare Earth".
Largest deposits in China, Brazil and USA. Originally waste products from extraction of other metals. Today mined for high-tech industry.

Extraction:
Use of acids --> formation of radioactive waste. This makes mining expensive. Low environmental regulations and cheap labor --> development mass production (China) 2010 approx. 98% of SEM production (worldwide) from China. Export restriction kept world market prices high.

Different reactions of the industry:

Mines newly opened or reopened
Industrial processes developed --> raw materials in demand to be obtained by recycling --> e.g. magnets

Consumer side has reduced use of SEM --> replacement by alternative materials.
