Recyclables

I like to collect misc papers, envelopes, newspapers, empty plastic containers such as shampoo bottles, washing liquid bottles, bottles for mineral water; cardboards; cans; glass bottles and keep them separately before sending them to the recycling place. I plan to store them in dedicated cupboard. But where do I put the cupboard?

1. Under the stairs

2. In the utility room

3. In the porch

4. In the backyard
