The £2m investment comes after the Edinburgh-based firm successfully established the IndiNature Mill in the Scottish Borders and with the production line now operational.

The investment will be used to underpin a planned second stage of CapEx projects to accelerate growth, including upgrades and additional production equipment to improve performance and manufacture new insulation products. The investment will also support recruitment to develop the Executive Team for the next stage, and capital projects to further reduce the embodied carbon in IndiNature’s already carbon negative insulation.

Andy Clapp, executive director - investment portfolio management at the Scottish National Investment Bank, said: “We have seen IndiNature go from strength to strength since our initial investment in August 2021 and are delighted to continue to support them through this planned scale up stage.

“The work of this company continues to support the delivery of the Bank’s missions in developing innovative solutions to drive the industry’s transition to net zero.”

Industrial Nature CEO and co-founder Scott Simpson said: “We would like to thank all the local engineers and other contractors who have worked with our fantastic Mill team and machine suppliers to establish production at the Mill and secure this second phase of investment - a big milestone.

“We’re grateful to have an impact investor like SNIB following on their original investment for this next stage of growth - an investor aligned with our mission to make positive impacts on scale for the climate and people’s health.

“More than ever we need to urgently insulate homes in the UK with appropriate materials - natural products like ours not only insulate, the materials they’re made from are also carbon negative.

“This investment is speeding up our ability to deliver healthy, low carbon products at high capacity to the market. We’re very much looking forward to accelerating growth this year.”

The new investment of £2m follows on from an initial £3m investment by Scottish National Investment Bank in 2021, which unlocked a further £800,000 in grant funding from Zero Waste Scotland’s Circular Economy Investment Fund and £250,000 from South of Scotland Enterprise, has been approved following the success of the business to date, including the launch of IndiNature’s natural fibre insulation IndiTherm.

The business is now in a prime position to scale across the UK and internationally in a growing natural fibre insulation market, so the investment also supports the opportunity to appoint an ambitious, dynamic and commercially minded CEO to join the executive team to lead the business for this next phase of growth.

IndiTherm is a flexible thermal insulation batt made from industrial hemp sourced from farms in the UK. Unlike conventional insulation materials, it helps tackle climate change by having a net capture of carbon.

IndiTherm by IndiNature is the company’s first product - they continue to develop and manufacture new bio-based insulation for retrofit, new build and offsite construction, with high-density thermal and acoustic IndiBoards and its full IndiBreathe system to be launched in 2023.
