I hate polystyrene and Bissell carpet cleaners lies right on the box.

I hate polystyrene and other single-use packaging materials. This single image explains the issue with non-recyclyeable non-biodegradable fragmenting plastic. This bird will be dead soon.



Often used in product shipping boxes as a bulking and holding material.  Alternatives exist and have been widely used by Mobile phone and other product shippers including Apple.        https://www.moldedfiber.com/eps-alternative.html

Bissell carpet cleaners are a great machine but the product packaging sucks. Particularly because they have "Sustainable packaging design" boldly printed on the box. The lie of that is just inside with three blocks of polystyrene. Shameful.  The tide is turning in the global awareness of ocean pollution by plastic debris calling out such hypocrisy can only serve to drive the message home.  

At time of writing the URL on the box www.bissell.com/SustainableDesign is redirected to a UK Bissell shop website. Message implementation fail.






Bissell was asked for a comment and this is included below. No mention of the broken URL or acknowledgement of the sustainable packaging message and polystyrene block mismatch.


PS: This article does not refer to Poly Styrene the late singer with X-Ray Specs. :-)
