Environmental education

Collection only works if cartons are sorted right. We run hands-on workshops for our partner cafés, using real cartons from our routes.

A carton thrown out with ordinary paper can’t be recycled, but most people are never told that.

What a workshop covers

Whether a carton gets recycled depends on the person who throws it away. That’s why we teach as well as collect.

Step 1

The material

What a carton is made of, and why it’s worth recycling.

Step 2

How to sort

Empty and rinse it, take off the cap and straw, then flatten it. Everyone practises with real cartons.

Step 3

Where it goes

Where a carton goes after the café: the sorting centre, the paper mill, and what comes back.

Step 4

Who it reaches

The local households who receive the recycled tissue.

Why cartons get lost

Mixed with paper. Cartons thrown out with regular paper can’t be recycled, and few people are told how to sort them.

Nowhere to go. There’s usually no separate bin for cartons, and public sorting centres don’t process them separately, so most get thrown away.

A stalled market. Imported pulp is cheap and there’s little demand for recycled products, so even collected cartons often go unused.
