Packaging manufactured from captured CO2 emissions
Manufacturing packaging from a biodegradable resin manufactured using a blend of polypropylene carbonate (manufactured from captured CO2 emissions) and starch
In Development – In October 2010, Cardia Bioplastics completed a first production run in Australia of carrier bags manufactured from the CO2S resin. The company is currently working to optimise the technology by increasing the PPC content and the renewable resource so that up to 60% less virgin oil will be used when compared to currently marketed biodegradable oil based products. Cardia are now ready to fully commericalise the technology and are negotiating with suitable partners with oil or gas wells or refineries producing CO2 emissions.

Details

To manufacture this resin, pollutant CO2 emissions are captured prior to being released to the atmosphere. The pollutant is then transformed into polypropylene carbonate (PPC) and blended with renewable starch material using the company's in-house blending technology. The resulting resin is then used to manufacture film.
Cardia Bioplastics is working towards accreditation to international compostability standards for the resin, trademarked as CO2S. The company claims that carrier bags manufactured from CO2S will be supplied at prices below those of current compostable carrier bags. There is no detail as to whether food contact approval for this material has been tested, although other Cardia products do have food contact approval.

Potential Benefits

The potential environmental pros and cons of this material need to be considered. The comapny identifies the main environmental benefit of this material as being reduced consumption of virgin oil for the production of plastics.

Intellectual Property

Cardia Bioplastics has a patent pending specific to the blending technology used to manufacture the CO2S resin.

Consultant View

Film manufactured from the CO2S resin is currently being used to manufacture carrier bags, although it can be envisaged the film could be used to manufacture other packaging film products providing the necessary performance and barrier requirements can be fulfilled.
 
Capturing CO2 emissions is a positive activity, but only if these are then stored. The compostable nature of the material may mean that the emission is merely delayed for a short period rather than prevented. In this case, the environmental benefits become less clear. More information is required from the manufacturers as it becomes available, including the environmental life cycle impacts of this material.
 
There are a number of research initiatives looking at capturing CO2 and using this to manufacture plastics. Research projects are underway in Europe and in the US, and interested readers are encouraged to search the Internet for a fuller picture.
