Plastic, where do we stand?


The health of the ocean is close to our hearts and as a company we actively seek out the most environmentally friendly packaging available.


So why the plastic tub?


We have been experimenting with alternative packaging since we started in 2008, and still to date the issue is finding a suitable alternative to our current recycled food grade PP5 plastic pots.


Not to get all sciencey, but, salt is hygroscopic and therefore the packaging we require needs to have a vapour barrier and last past 3 years and beyond.  Using PP5 we understand it to be the safest plastic to heat or freeze and re-cycle, and definitely not seen as a single use plastic material.  It is low in carbon footprint compared with other alternatives too. 


Packaging options could include glass, however unfortunately glass has a larger carbon footprint due to the energy used in production, low bulk density for transport (meaning more lorries on the road) and much higher product weight – that said, it is very easy to recycle.


Whilst reducing plastic should be every producers aim, it is worth noting not all plastics are the same with different levels of reusability and recyclability.  At Cornish Sea Salt we believe in recycling and recycled materials whilst there is no known other viable options … YET.


Generally speaking, our sea salt pots have a long shelf life in the consumers’ kitchen and we receive lots of encouraging news about the ideas they have reused the pot for – anything from a succulent plant pot to a soup container or perfect to freeze any kitchen left overs.


If you look along the salt aisle in the UK and internationally you can quickly see that we all use plastic (yes even the cardboard box has single use plastic inside) some use laminated plastic bags which we reviewed, but dismissed as that can’t be recycled.  There are glass options for premium salts but then again you pay higher costs with a larger carbon footfall as mentioned.


We are carefully monitoring developments in packaging and will make any changes we can, but in the meantime we suggest keeping up the upcycling and recycling of our pots. 


Lastly and importantly, we WELCOME researched alternative packaging ideas to help us move towards sustainable products, now or in the future – please email:  Eagerly waiting
