noble obligation

The title sounds exaggerated. Anyway, let me tell you today's story.
This morning Yuki and I went to a city garbage center to dispose of our FUTON. which is a kind of mattress. There were two sets of FUTON. They were too big to dispose of them as a home garbage.
The  cheapest way to dispose of them is to take them to the center by ourselves. It's free.
The next cheapest way is to ask to take them to the city garbage office. In this case each costs 840 yen, so total it costs about 3500yen. And it takes three or for days for them to come after we call.
The next cheapest way is to ask to take them to garbage & recycle company. In this case each costs about 1000 yen, so total it costs about 4000 yen. As soon as we call, they come to take them.

Nowadays, disposing of something costs money.
On the other hand recycling is meaningful, if someone can use it.
Our FUTON is not so bad, so I look for recycling sites. FUTON seems to be used in poor foreign countries. Some NPO groups collect FUTON. --- They don't earn money, but if we send FUTON, we donate the export fee. It costs more than 7900 yen, because FUTON-sets are very big and heavy.

If we were very rich, we might have donated them to a NPO group.
