Engineered for how industry actually works.
encircol material development is designed around process compatibility from the outset. Testing, validation and application development are built into the process, not an afterthought.

Ambition meets
specification.
Materials used in construction, energy and manufacturing are not chosen because they sound responsible. They are chosen because they work. They must be processable, repeatable, reliable, safe, certifiable and commercially relevant.
encircol begins from that reality - not from a sustainability campaign, but from an engineering discipline.

BioPRO® is not a concept.
It is certified and in commercial production - proven across aviation, automotive and mass transit interiors through Scottish Leather Group.
The same technology is now being applied to engineered material formats for demanding industrial applications - tested, processable, form-fitting.

specification.
encircol materials are not chosen on environmental credentials alone. They are chosen because they work - tested, certifiable, and designed to fit the processes and specifications that industry actually demands.
Waste stream to value stream.
From collagen-rich by-product to higher value material programme.
Scottish leather manufacturing generates a collagen-rich stream that has historically had limited material pathways. encircol exists to change that - by applying engineering rigour to create materials that carry a strong relative environmental advantage, and earn their place in demanding industrial supply chains.
Collagen stream
A high-value biological resource generated as a by-product of leather manufacturing - material that might otherwise have limited end-use options.
BioPRO® technology
Proprietary technology that applies engineering rigour, process chemistry and form-fitting capability to transform the collagen stream.
Engineered material
Precision-engineered bio materials with properties competitive with conventional alternatives - tested, certifiable, processable.
Industrial application
Construction, energy and advanced manufacturing sectors. Materials that earn their place through performance, not only environmental advantage.
Built on proven BioPRO® technology
The technical foundation behind the encircol material technology. BioPRO® is already produced, certified and in market - as the interior element of seating solutions in aviation, automotive and mass transit sectors through Scottish Leather Group.
Against that proven background, encircol is developing application of the technology into advanced industrial formats - materials that carry a strong relative environmental advantage and earn their place through performance.
Industrial foundation
BioPRO® is produced and certified by Scottish Leather Group - the industrial partner behind encircol.
A better material pathway.
Environmental performance data is subject to ongoing testing and validation. Claims will be substantiated through formal certification and independent assessment. encircol does not claim full circularity - "circular advantage" and "relative circularity" are the appropriate framings.
Rooted in over 200 years of Scottish manufacturing.
encircol is part of Scottish Leather Group - one of the world's leading manufacturers of high-quality leather, with operations in Bridge of Weir, Scotland.
SLG's manufacturing heritage, collagen expertise, net-zero Scope 1 & 2 credentials and responsible production practice form the credibility foundation on which encircol is built.
