Inside this book, Designing Sustainable Packaging by Scott Boylston I came across a case study on Innocent smoothies. I found some information on their beliefs and I think they are quite a respectable business. They developed the first ever "100% PCR drinks bottle (PET)" which highlights the fact they care about the environment.
Innocent strive to be ethical where possible and the book also explains more information on 'the big knit' project. "In 2006 alone, 230,000 hats were knitted, raising over £100,000." Also 10 per cent of Innocent's annual profits are donated to charities in countries that supply fruit for Innocent's drinks. Both images scanned in from the above book pg.80+81.
