The short answer is you will not be satisfied with recycled beads.

Recycled beads, sometimes referred to as eco-beads or eco-beans, are often purchased to promote environmentalism or save money. Essentially, this material is recycled polystyrene that has been cut or ground into small, irregular particles. While some of these pieces are vaguely round and pill-sized, most of them are abnormally shaped chunks that are extremely soft but hardly resilient.

Recycled beads were never meant to be used as a bean bag filler. Most of them were once packing peanuts or packing blocks. Probably used in shipping boxes for electronic devices, computers, and other products. When used in bean bags, recycled polystyrene beads do not produce constant pressure on your body. This makes the furniture soft, lumpy and otherwise uncomfortable. Also, they do not provide the same ergonomic support as virgin beads do.
