Took this form a very interesting article here. I will be looking into them more closely in the future
Regarding energy use and carbon footprints, the lowest ‘footprint’ container by Jiffy is the CarbonLite. It is made primarily from low-e bio-based plant starches, and uses less total energy than either plastic pots or pots made to be compostable. Roelof Drost from Jiffy talks about how this low energy pot came to be: “Instead of focusing on the end of the life cycle of a product (recycled, composted) here we focused on the beginning of the life cycle of the product and asked ourselves how much energy is used to get to the desired result. Taking that route, we have created a container with an extremely low carbon footprint. This is what it should be all about — using as little input material as possible to get to the desired result. These pots are usually less expensive to make than other bio-based pots. That’s real sustainability.”
The CarbonLite pot is Vinçotte OK biobased certified. On a basis of the formulated percentage of renewable raw materials the pot is rated two-star bio-based. This means that more than 60 percent of the raw materials are renewable and in the case of CarbonLite pots are renewable plant starch based. The pots are recyclable.
