  1. Disposing batteries as domestic waste is not a problem, so it is not necessary to dispose them in a special place.

It seems that it is possible to reduce our domestic waste at maximum. Bea Johnson, born in France and currently living in USA, shows how has she made possible to reduce the waste of her family to less than a kilo in a year.

  2. Reduce what you need. Having at home just what you really use.
  3. Reuse. Using everything that is disposable on a second alternative and buying second hand.

  5. Rot. Composting the rest.

Sustainable development encompasses uncertainty, complexity and challenge. It can only be achieved through the action of people who share the vision of sustainability and has developed some specific competences that provide them with the interest and commitment to act towards sustainability.
