Oyster shell recycling plant that cost 16 billion won has been shut down for the first year

1. Build a processing facility for 16 billion won to process oyster shells

2. The facility itself is poor, so an additional KRW 2 billion was spent and it is still in test operation.

3. Even if you process it like this, there is no place to sell it.

4. There is a good harvest of oysters this year, so there will be more shells.
