18 Dec 2018 --- New research by Which? has found that the packaging of popular Christmas chocolates can constitute up to 42 percent the products’ total weight. After investigating the UK’s top 13 best-selling boxes of chocolates, the consumer lobby group pinpointed Ferrero Rocher Collection as the “worst offender” with 42 percent of the total weight taken up by packaging and only 11 percent of that packaging being recyclable. In response, the chocolate manufacturer points to the “fundamental importance” of the distinctive packaging in protecting the product from damage.
