When you are at home on a day with nice weather, have you ever noticed a truck driving slowly while announcing “I will exchange used paper and magazines for toilet paper?”
If you bundle old newspapers and magazines together and keep them in your house instead of throwing away such recyclables in the garbage, you can receive one roll or more (depending on the amount given) of toilet paper from the truck driver. When you notice the truck driving by your home, stop it and hand the old newspapers and magazines to the driver.
This exchange service kills two birds with one stone. That is, it contributes not only to the protection of the global environment but also saves you money. It may be hard to notice the voice spoken in Japanese and the driver probably speaks only Japanese, but please give it a try.
