Short answerNo. PSM blends contain a large share of PP plastic and do not fully break down, so we describe PSM only as ‘partially bio-based’ and never as compostable.
In more detail
PSM is a lower-cost option and is accepted in some markets, mainly the Middle East, Southeast Asia and Latin America, and in the USA when sold without a compostable claim.
It is not offered for the EU, UK, Canada or Australia / New Zealand, where plastic cutlery rules apply.
