The story

Zara sits beside Isla at a classroom table studying a small cream card with a tank drawing and two destination pictures, an energy cabinet and a field, while Eddie leans in and Amina stands nearby.

In class, Zara studied a card with a tank drawing on it. She noticed two arrows leading away from it, one to an energy cabinet and one to a field.

Eddie lays one long cream caption strip across both destination pictures while Zara looks thoughtful and Isla and Amina watch kindly.

Eddie laid one long label across both pictures, as if they were the same thing. Zara looked at it and thought hard.

Amina holds a small model of a closed energy cabinet beside its matching card while Zara and Isla listen, and the field card sits apart.

Amina held up a little model cabinet. She explained that one branch is biogas, which goes to suitable energy equipment.

Zara: “Can you show me how that works?”

Amina holds the field picture card next to a small tablet showing a checking page while Zara and Isla watch, and the cabinet model stays apart.

Next, Amina picked up the field picture. The other branch is digestate, which has to be checked before it can be used as a suitable fertiliser.

Zara, beside Isla, takes away the long strip and puts one small cream tab under the energy card and another under the field card while Eddie smiles.

Zara took away the long strip and put a separate label under each picture. Then she explained the two branches, and Eddie smiled.

For grown-ups: The two labels are: biogas, which goes to suitable energy equipment; and digestate, which is checked before it is used as a suitable fertiliser. They are two separate routes from the sealed tank.

Zara and Isla place the finished card on a low shelf while Amina checks it and Eddie sits at the table with the cabinet model.

Zara and Isla put the finished card on the shelf. Its two branches stayed apart, so everyone could see two different outputs.

Draft, 20 October 2026. The words and pictures are not yet reviewed by an educator. The story follows the outline in our story guide.

The real-life bit

A bio plant gives two separate outputs: biogas for suitable energy equipment, and digestate, which is checked before it can be used as a suitable fertiliser. Household scraps should never be fed to farm animals. Save good food first, and follow your council’s own rules for food scraps. Gullbrae is made up. Your council’s own rules are the ones to follow.
