New Leaf Chocolates has added a plant-based packaging for shipping its premium chocolates, while Kenco, a UK coffee brand, is promoting its refillable packages.

For New Leaf Chocolates, which formerly used polystyrene foam boxes, the challenge was to preserve the delicate nature of its chocolates while shipping to states such as Florida, New Mexico and Texas where the chocolates would routinely be 90 degrees or higher during postal routes, according to a press release.

The company chose to adopt its GreenPod packaging system because it uses plant-based materials that are recycled, recyclable or biodegradable. The company says it will continue to work with its packaging design in order to accomodate larger chocolate products.

Meanwhile, in the UK, Kenco is encouraging consumers to use its Eco Refill packaging, as opposed to glass jars. The new packaging uses 97 percent less materials than the old, reports MarketingMagazine.

Kenco is supporting its education effort with a $12 million advertising campaign.
