For the first classe Neil presented the digital revolution and the changes it has led. Several past year final projects were be presented. To finish the classe each node presents its operation and its specificity.

Assignments

• This week we had to plan and sketch a potential final project.

Idea of final project: Worm composter¶

Concerned by the global warming and as urban people i tried to find a maneer to reduce my environmental impact. Like many French I am dependent on fossil and atomic energy. I wish I could do without it in the near future, but I am not able for the moment. In the meantime, I cycle, consume local products (where possible) and try to reduce my waste.

If it is easy to compost waste when you live in the countryside or just when you have a garden that allows it, it is more complicated when you live in town and have no garden.

The worm composter is a beginning of solution because it allows to reduce significantly the volume of waste and it can be installed indoors. But there are several obstacles to its development:

• Psychological: the human knows how to generate waste but they must quickly disappear from his sight … with a worm composter the waste is degraded slowly and remain a moment in the home … and in addition there are worms that crawl under the rubbish

• Use: Start a worm composteur is not necessarily easy. This requires observing the evolution of the waste and properly balancing the inputs. If this is not done correctly, smells, midges or other nuisances may appear.

• Drainage: when there is no garden where to value the compost, how to do?
