Keracol + Bulmer & Lumb

The Company

Keracol develops technologies for the extraction and refining of natural products, most notably colourants. They use the active ingredients extracted from residual fruit skins and vegetable peel from the juicing industry and turn them into functional products.

Bulmer & Lumb Group produce a wide product range from raw wool top, top dyed wool, package dyed yarn and synthetic fibres.

R&D Focus:

We aim to validate and industrialise the prototype of an innovative continuous process for manufacturing wool, dyed with natural bio-colourants.

With Bulmer & Lumb’s expertise in colour blending and colour matching, we will achieve a range of colours on natural fibres, thus bringing to the market a genuinely sustainable range of “naturals-dyed” products that are not yet available to the general market.

The project will launch in autumn 2021.
