There are a number of ways you can recycle/reuse the wool liners including:-

– picnic hampers
– hanging baskets
– pet baskets
– cushion stuffing
– Homework projects
– Donation to homeless or animal shelters
– Pipe lagging
– Draught excluders
– Protection for plants/trees from frost
– Feeding roses and keeping slugs off plants
– Keeping takeaways warm
– Keeping drinks/food cold on the beach
– Craft projects
– Van/Car lining
– Pads for gardening

We are open to any other suggestions too! We are also new and inventive ways. Post these on social media using #letsboxclever.

If you aren’t looking to re-use the Woolcool Liners, simply remove the plastic liner, this can be put in with the standard plastic recycling, then just put the wool liner into either a compost bin (if available) or dig into the soil in the garden, as the wool will release valuable nitrates back into the soil as it breaks down. Some local authorities will accept the wool in household garden waste bins, it is just a matter of checking with the local council to find out what recycling facilities are available in your area. Even if the wool going into the general waste, it will break down in landfill.

We only use 100% sheep wool. As an ethical and environmentally responsible business, we are very sensitive to the welfare of animals and in particular sheep, from which our amazing, sustainable insulated packaging material is made. We have a lot to thank the Sheep for! Adult Sheep of breeds which have continuously growing wool need to be sheared for welfare reasons, a heavy fleece not only causes a sheep to over heat in the summer but can provide an ideal environment for parasites on the sheep. The RSPCA advise that a sheep must be shorn at least once every year for their own health, to keep them comfortable and free from parasites. Shearing can only be carried out by a licensed shearer to ensure that the sheep is handled carefully. We do not use pulled wool.

After being sheared, all of our Wool is washed and scoured in the UK to ISO standard. All wool sourced is heat treated and no harsh cleaning chemicals are used. The wool goes through a series of hot baths where it is washed and scoured using only hot water and a mild detergent. It then goes through industrial dryers. This process means our wool is both clean and suitable to use with food and pharmaceutical products and does not carry any nasty chemicals!

Questions around the smell are usually linked to worries about cleanliness and linking the smell to the toxins etc. Wool is washed and scoured to ISO standards to ensure cleanliness. We perform monthly tests to ensure it is completely clean and free of any toxins that can leach into food/pharmaceuticals. As with any material/object, man made or natural, it has its own smell. Typically if the Wool has been stored with other wool, it will smell stronger, but once it has been taken out of the initial delivery box, that smell will dissipate. To remove the smell we would have to add chemicals, which would negate our natural product and could potential damage the fibres. Of course, we love the smell, as what better way is there to prove our product is 100% natural?!

100% felted sheep’s wool, sealed within recyclable industry grade polyethylene wrap.

Sheep’s fleeces are naturally washed, scoured and felted to make the insulation material to the required thickness which is then cut into strips and sealed within a recyclable polyethylene industry grade wrap.

Wool fibres are incredibly effective at absorbing moisture from the air which minimises humidity and condensation to maintain stable temperatures. The recyclable industry grade wrap which encloses the wool in Woolcool is micro-perforated to allow the fibres to breathe and create the natural cooling system.

With ice sheets used to maintain the cool temperatures for pharmaceutical goods, the Woolcool insulation has been proven to keep contents between 2°C – 8°C for at least 72 hours.

Woolcool does need ice packs, although the efficiency of the wool liners means they need significantly less than the alternatives. Please contact us to discuss your particular application.

Yes, wool is excellent at maintaining temperature and has been tested for ambient and warm applications.

Yes, wool is perfectly safe. The natural washing and scouring process requires no chemicals, additives or further sterilisation. Wool fibres have been scientifically proven to absorb and lock-in bacteria and dangerous chemicals. The wool is sealed within recyclable, industry grade polyethylene wrap to prevent the fibres coming into direct contact with packaged contents.

No. After the natural washing and scouring process, the wool only has a similar smell to a new, pure wool jumper! It is also sealed within recyclable, industry grade polyethylene wrap to prevent contents coming into direct contact with the wool fibres.

This depends on the condition of the Woolcool after use, for example whether it has been ripped or if contents have spilled out or seeped into the insulation. If the Woolcool cannot be re-used as it is, the wool can be recycled and re-used or put to many good uses from lagging pipes to insulating garden plants from the frost!

The wool is sustainable, recyclable, compostable and biodegradable. The industry grade wrap is also recyclable.
