Woola protective packaging is made of leftover wool, bio-based binder and, in case of the Wool Envelope, recycled paper — which are all biodegradable materials. Even if they end up in nature or in landfill, they’ll eventually❊ break down into biomass, CO2 and water, without leaving any microplastics behind (unlike the classic bubble wrap/mailer made from polyethylene (PE), the main source of microplastics globally).The two layers of a Woola envelope are easily separable so both materials, wool and paper, can easily be reused or recycled. The main challenge of plastic bubble wrap envelopes is that the different materials are difficult to separate, which makes it nearly impossible to recycle in most countries. The only option for them is landfill, or to be burnt to create energy.
❊ The timeframe depends a lot on the conditions of the environment (temperature, moisture and oxygen levels, microbes) so it can be from some months to some years, but compared to plastic packaging that can take up to 1000 years to decompose in landfills, it’s so much lighter on the planet.**
