Composting

Composting is a natural process in which food scraps and other organic materials are transformed into fertile soil. Instead of throwing these materials away, we can use them to help nature.
Composting is a simple way to take care of the planet. When we do it:
✔ We reduce the amount of waste
✔ We decrease pollution
✔ We make use of microorganisms
✔ We create natural fertilizer for plants
It also helps children understand how nature works and develop responsible habits from an early age.
✔ Fruit and vegetable scraps
✔ Dry leaves
✔ Grass clippings
✔ Coffee or tea grounds
✔ Eggshells
🚫 Avoid: meat, dairy products, oils
Making compost is easy and fun. Just follow these steps:
You can do it in the garden or use a compost bin. You can also use a bucket or a box with holes to allow air to circulate.
Save fruit and vegetable scraps, eggshells, and other natural materials. It is important not to mix them with plastics or other waste.
For compost to work well, mix wet materials (such as fruit and vegetable scraps) with dry materials like leaves, cardboard, or dry grass.
Stir it from time to time to let air in. This helps microorganisms work better.
The compost should be moist, but not too wet. If it is too dry, you can add a little water.
Little by little, with the help of microorganisms, everything turns into dark soil with a forest-like smell.
When it is ready, you can use it to nourish plants, pots, or your garden.
If you add worms, the compost breaks down faster and produces higher-quality fertilizer. This process is called vermicomposting.
Composting is a simple and natural way to teach children to care for the environment at home. Through small actions, they can understand that waste is not garbage, but a resource that can be transformed and returned to nature. Learning this from an early age helps develop responsible habits and greater environmental awareness. Every small action counts, and starting today can make a big difference for the planet of tomorrow.

After reading this Eco-note, we invite you to keep learning with simple and fun activities to do in the classroom or at home. With small actions and big ideas, together we can help take care of our planet.


Observe during the day what organic waste appears: fruit peels, vegetable scraps, dry leaves and other natural materials that could become compost.

Design a composting poster!
Using a sheet of paper or recycled cardboard, create a poster with two groups: “Goes in the compost” and “Does not go in the compost”. Then draw or paste pictures of different types of waste and place them in the correct group.
This way, we can learn in a fun way which materials can turn into fertile soil and which cannot.

Download the coloring page and color it.


Build a mini compost bin!
Using a transparent jar, a recycled bottle or a small box, make a mini compost bin by adding layers of soil, dry leaves, small pieces of fruit or vegetables, and a little paper. Watch how, over time, nature transforms these scraps into fertile soil.


Save fruit and vegetable peels and separate them from the rest of the trash. You are already starting to make compost!
