Based on available information from 2015, no, the bags that contain LEGO bricks within a set are not recyclable.
Why LEGO Set Bags Are Not Recyclable
According to a source from October 22, 2015, the plastic bags found inside LEGO sets, which hold the individual brick groups, are actually not recyclable. This is a direct statement regarding the composition and recyclability of these specific bags at that time.
Filling Levels of LEGO Bags
The same source also mentions a detail regarding the bags' filling level. It notes that the bags aren't filled entirely. This is explained as a deliberate design choice by The LEGO Group (TLG) to make the bags more flexible and loose. This flexibility helps them fit more easily within the larger box of the LEGO set.
It is important to note that this information pertains to the status in 2015. LEGO's practices regarding packaging materials and sustainability may have evolved since then. However, based strictly on the provided reference from that date, the conclusion is clear.
