Certainly foam is not recyclable. Thanks Louis for sharing this photo as part of the Young Sustainability Champion (Junior) Programme
This question is difficult. Daddy and mommy have to search the Internet to find the answers.
We found a very good website https://www.ecoscraps.com/blogs/sustainable-living/76411652-a-simple-list-of-what-can-and-cannot-be-recycled
1. Polystyrene (foam) cannot be recycled. Examples are food packaging for fruits and egg foam packaging.
2. Mixed material bag cannot be recycled. Example is potato chip bags. My daddy said that the bag has an aluminum layer in the bag and recycle plant cannot separate the metal and plastic.
3. Packaging material that has special coating cannot be recycled. Example takeaway coffee cups. The cup has a plastic coat and cannot be separated in the recycle plant.
