Innocent, the UK's leading smoothie brand, is to introduce the fully compostable PLA plastic bottle to its range of thickies and smoothies this autumn.

The PLA bottle has created excitement as it is derived from corn starch, an annually renewable resource. It can compost down in 40 days. Also, producing PLA is a totally carbon neutral process; no greenhouse gases are emitted in its production. However it is more expensive than traditional PET.

 "Yes, this packaging definitely costs us more," confirmed Richard Reed, co-founder, "but we will not be passing on that cost to consumers.

"Just as we're prepared to invest an extra 10% extra for locally-sourced, or ethically-accredited fruit, so with our packaging. We believe this is the right way to do business."
