We know there is always more we can do, but Woolcool® is determined to play its part in creating a more sustainable world through environmentally-friendly insulated packaging.

Woolcool® thermal insulated packaging products help companies and consumers reduce, reuse and recycle packaging as set out by the Government and following guidelines by WRAP (Waste & Resource Action Programme).The wool insulation is certified compostable and biodegradable, releasing valuable nitrates back into the soil.

Any plastics used are easily recyclable at local authority waste depots.The cardboard delivery boxes are produced using recycled materials with FSC standards, and are easily recyclable at local authority waste depots.

Using Woolcool® as insulated packaging for food and pharmaceutical goods, significantly reduces the rate of the Packaging Waste obligation versus conventional materials. At the end of its useful life as packaging, the insulation liners or felted wool can be re-used for a variety of purposes.

Why Woolcool®?

Woolcool pioneered the sustainable packaging revolution over two decades ago and have researched, and created innovative solutions for delivering perishable goods, ever since.

Unlike alternative solutions, there’s no need to compromise on sustainability or performance, when Woolcool offers both! We have harnessed the amazing natural properties of 100% sheep’s wool to provide insulation that delivers your products in perfect condition, without harming the planet.

Woolcool uses fully traceable materials and processes which are ISO certified to ensure consistent, clean, high-quality supply.

Other benefits of using wool includes its ability to absorb moisture from ice packs, preventing your products from arriving damp, and reducing damage from any accidental spills during transit. Its flexible nature also protects them from the impacts of courier delivery. 

Our rigorous cleaning process and the natural anti-microbial nature of wool also means that it has a much lower toxicity level when compared with alternative textiles.

See how Woolcool measures up to other solutions here.

How does it perform?

Unlike traditional solutions Woolcool® does not simply act as a barrier that slows down the heat exchange from outside, to inside the package. Instead, wool fibres breath in air and moisture from within the box or pouch, to actively help in maintaining temperatures, as they have evolved to do for sheep over thousands of years!

Woolcool® can keep products at fridge temperature, frozen, ambient, or even hot for up to 72 hours, and sometimes beyond, but performance does vary by product, temperature range and on the amount and quantity of ice used.

We have rigorously tested our solutions to industry standards and our expert team are on hand to make the best recommendations for you, so please get in touch to discuss your requirements.

How is Woolcool® sustainable?

We have specifically chosen to use materials that are compostable or recyclable, renewable, easy to dispose of and available in abundance, so that at the end of its life, our packaging does as little damage to the planet as possible. In fact, as wool composts it even adds nutrients back into the ground!

Due to the high performing nature of the materials we use, it also means that overall, our packaging uses less material and as a result, produces less waste compared to alternatives.

We were the first UK company in our sector to become B-Corp certified, are actively working towards meeting UN’s outlined Sustainable Development Goals and all of the paper and cardboard we use is FSC certified.

Why do we use plastic film for our packaging?

We’re proud that our packaging range is up to 95% plastic free, utilising natural materials such as wool and paper.

We are however very aware that it is important to use the right material for the right application, and all of our Woolcool® insulation liners are wrapped in a grade 4 recyclable polyethylene film. This is to ensure that they meet hygiene requirements for both food and pharmaceutical applications, and also to increase the reusability of the insulation. Due to the nature of our packaging being designed to work alongside ice packs, which produce condensation during use, waterproof materials also increase the durability of our packaging.

The additional bonus of wool is that it absorbs moisture really well to eliminate this moisture, and you may notice tiny perforations in our film which allow the wool to do this still, despite being wrapped.

We are always researching and staying at the forefront of developments of plastic alternatives in the sector, however we are also keen to fully ensure that a material is fit for purpose, as well as genuinely being better for the environment.

There are several ‘bio’ and ‘compostable’ plastic alternatives now available, but these often require very specific environments to break down, without which they can take many years to degrade just like traditional plastics. Whether they leave behind traces of bioplastics which can still be harmful to the environment, is also questionable and further long-term study is required.

For the time being, we have opted to use a material which our end users know how to dispose of correctly, with total transparency, until we are sure a better alternative is available.

What if i’m vegan?

By name and nature, Woolcool® is made from wool, which comes from sheep.

Despite this we are an extremely ethically-minded company and do have a number of vegan and plant-based customers on board, who support Woolcool’s environmental values and what we are trying to achieve.

We do not kill sheep for their wool, and we do not use lambs wool. In order for a sheep to stay healthy it must be sheared. Very few breeds of sheep will shed their own wool and so both DEFRA and the RSPCA state that sheep need to be sheared at least once every year as part of their welfare. 

As a result, there is plenty of Wool around, if this was not used, it would probably end up burnt or dug back into the soil. This would be a massive waste for a material which such amazing and sustainable properties; wool is compostable, renewable and forms part of the natural carbon and bio-economy cycle. 

We believe it is key to any business that wants a positive future legacy to consider the Planet and People when making our business decisions. We believe in business as a force for good and the B Corp certification displays this, along with us changing our inherent Articles of Association to commit to this in writing. 

Woolcool® was originally created as a solution to replace the polystyrene box alternative over two decades ago. Since then, we have done lots of research with top universities to delve into the benefits of using wool as a material and in the last year alone, we have saved more than 2,000 tonnes of polystyrene from going into landfill, or our oceans.

We’re extremely conscious of the choices we make in our own wool supply chain. Sourcing our wool only from Britain, Europe and Turkey, we ensure that the wool is from sheep that are well maintained and cared for by law, and it does not require ridiculously high shipment miles. We also do not rely on mass deforestation for our insulation. From a recent Carbon Footprint Analysis conducted, our carbon footprint was found to be extremely low.

To read more about our ethical stance practices, you can head over to the dedicated Sustainability and Ethics page on our website, which included even more information.

If you are still not convinced by all of the benefits of wool, we do have a 100% plant-based fibre alternative available.

How many times can Woolcool® be reused to send products?

Woolcool® has been designed to be as sustainable as possible as a single use application, but due to its flexible and durable nature, it is also reusable… helping out with your CSR and cashflow!

Some of our customers reuse the Woolcool® liners for their food deliveries up to 10 times. Of course, its reusability depends on the condition of the liners after use – for example, if it has been ripped or if contents have spilled out or seeped into the insulation, we would not recommend reuse.

Popular ways of collecting liners back for reuse is via dedicated company vehicles, or creating a courier returns scheme, like Abel & Cole or Naturaw.

How do i reuse/recycle Woolcool® at home?

As wool is such an amazing material, with lots of useful qualities, we recommend reusing the liners around the home and garden where you can, to reduce waste as much as possible. We have an awesome online community who share all of the clever ways they have reused their wool on social media using #LetsBoxClever.

If you have no use for the wool, it is certified compostable and can therefore be broken up and placed in with your garden waste. Alternatively, it can be home composted, or donated. The food-grade plastic wrap is recyclable. The correct way to do this varies by location, so we’d recommend recycling this in the same way you would any other stretchy plastic bags, such as at your local carrier bag recycling point.
