What is it made of?
The pen is made from a cork casing with metal aluminium parts. The refills are made of aluminium, but unfortunately do include a tiny amount of plastic on the top of the refill helping to denote the colour of the ink.
Where is it made?
The UK. The cork is sourced from Portugal.
Is it sustainable?
Cork – Cork comes from the bark of the cork oak tree. Cork is a wonderful material, it’s got loads of really useful properties, two of which are floating and being waterproof. Cork is nowadays often marketed as ‘vegan leather’ as the properties of cork make it an ethical alternative to leather. It is also naturally flame-retardant, and so is gaining in popularity for use as eco-friendly thermal insulation in buildings. If you are a fan of wine, cork is the most eco-friendly bottle stopper, as cork trees take in CO2, so the carbon footprint of corks is lower than that of plastic stoppers and aluminium caps. Portugal is the main exporter of cork; it is responsible for around half of the world’s production. Cork trees have to mature before they are harvested, once they are 25 years old, cork trees are stripped of their bark which is allowed to regrow for 9 years before the next harvesting. Cork trees live for around 300 years, so each tree can be harvested about 30 times. As the tree does not need to be cut down to harvest cork, it is considered to be a sustainable material in terms of its production, and it can be recycled. No cork is wasted during the production process, as it can all be used as components of varying qualities of the finished cork materials. Cork trees can grow in quite arid environments, so cork forests can help prevent desertification. Cork, being made from tree bark, is also naturally biodegradable. Cork trees are also lovely to look at – cork is one of my favourite materials if you haven’t guessed!
Aluminium – The rest of the pen is made of aluminium, which is the most abundant metal in the Earth’s crust, making up about 8% of it. Aluminium is very chemically reactive, so is mostly found combined with many different types of minerals. It has a low density and doesn’t corrode easily (although it does react to dissolved chlorides such as sodium chloride/salt), making it a very useful material, and is often used for transportation of other materials for these reasons. Although aluminium is an abundant element, deposits of ores which can be used to make aluminium metal are not as common as you might expect. China is responsible for most aluminium production. It is very energy-intensive to create, so most smelting forges are located in areas where electricity is cheap. The energy use is so high, that in the US aluminium production uses 5% of all the US’s electricity! This is why recycling aluminium is extremely important, as recycling aluminium uses only 5% of the energy it would take to create virgin aluminium, a huge difference. It is one of the most valuable materials for recycling for this reason, and recycling rates tend to be higher than for most other materials. Most aluminium cans will be made from recycled material or contain a high percentage of recycled content. Aluminium is one of the most easily recycled materials, as it can be recycled over and over again without any downgrade in quality, unlike plastic, which is ‘downcycled’ as the quality of the material decreases each time it is recycled.
Conclusion
If the pen is mightier than the sword and can be used to change the world for the better, make sure the pen you use to wield your words isn’t made of single-use throwaway plastic!
