It is currently installing solar panels on five of its showrooms, with an ultimate goal of becoming 100 per cent sustainable.
Big Save is also seeing strong consumer interest in what materials are being used in its products, where they are being made, and where they will end up.
“Now, and especially since Covid, people want transparency - they want to know where a product is coming from and what will happen to it in 40 years’ time, when it ends up in a landfill,” says McKimm.
Wool’s natural qualities, including being fire retardant and hygienic, make it an ideal replacement for foam filling and padding in furniture.
It is also biodegradable, which means it is much easier and safer to dispose of at the end of its life.
The company is also exploring other uses for wool including the installation of tightly-woven mats as fire-retardant ceiling panels or using them as a non-toxic alternative to weed-killer, to stop grass from smothering native saplings.
“Every avenue you go to with wool, you just start to say, well, this is a no-brainer - why wasn't this being done before?” says McKimm.
“We want to ensure our products are both sustainable and genuinely good for the environment - it's not easy, but it can be done.”
