A world full of mysteries that we hide under our feet, above our heads, and even in our own homes. One of the most interesting and important mysteries we are trying to solve is how to protect our Earth.

Earth Day is here to remind us that every step we take to protect our planet is a step in the right direction.

Do you know where to find the sorted waste bins in your school building? If not, you can find out that too in this blog article.

When and why do we celebrate Earth Day?

Earth Day is a celebration that takes place annually on 22 April. It was established to raise environmental awareness and encourage individuals and communities to support sustainable environmental practices. This day reminds us that we are all part of one ecosystem and have a responsibility to protect and preserve nature for future generations.

Waste sorting or a simple step to protect the planet

One of the most effective ways we can help protect our planet is by sorting our waste. Sorting waste means separating different types of waste according to their materials and then putting them in the right containers or collection points.

Why sort waste?

Conservation of raw materials: sorting waste allows materials to be recycled, reducing the consumption of natural raw materials and energy needed to produce new products.


Reducing waste to landfill: Recycling and composting reduce the amount of waste that ends up in landfills, which has a positive impact on the environment and human health.


Protecting nature and the environment: Reducing waste and using recycled materials reduces negative environmental impacts such as air, water and soil pollution.

How to sort waste properly?

Plastic (yellow bin): bottles, cups, food packaging and other plasticitems belong in the container marked for plastic waste.

Glass: Glass bottles and jars can be recycled. It is important to avoid putting glass in your regular trash because it is a material that can be recycled and reused.

Paper and cardboard (blue bin): Newspapers, magazines, paper wrappers, egg tray and boxes should be placed in the bin designated for paper waste. Metal packaging: Cans, tins, aluminium packaging, etc. belong in the metal waste container.

Biodegradable waste (brown bin): Food scraps, plant waste and other organic materials can be composted and used to create nutrients for plants.

Mixed waste (black bin): the mixed waste bin contains all rubbish that cannot be recycled or composted and is destined for disposal.

For example:
  • Used paper napkins and paper food wrappers.
  • Plastic bags and packaging that cannot be recycled.
  • Hygiene waste such as used pads, tampons, or diapers.
  • Other plastic items that cannot be recycled, such as toothbrushes, combs, etc.
  • Other materials that cannot be placed in separate waste containers, such as metal objects, glass shards, ceramics, etc.
  • Food packaging and food wrappers that cannot be recycled (e.g. chip wrappers, candy wrappers, etc.) unless they are clean and can be washed.
  • Other rubbish that cannot be placed in separate waste or compost bins, such as small pieces of textiles, plastic toys, rubber items, etc.

How can I sort waste in the school building?

There are several types of bins in the building - plastic, paper, mixed. These bins are in the common areas of the school and also in all classrooms. You can also drop off used batteries or small electronics at the main reception, our receptionists have a bin available.


Each of us has the ability and responsibility to contribute to the protection of our planet. Small changes in our daily habits, such as sorting our waste, can have a big impact on the environment. Earth Day reminds us that every step towards a more sustainable future is important. Whether we celebrate the day by picking up litter in nature, supporting green initiatives or simply by starting to sort waste, together we can create positive change for our planet.
