The leather industry gathered in Hong Kong this March, and the conversations that matter happened in meeting rooms and hallway exchanges as much as they did on stage. This year, Mindhive Global was a lead sponsor of the Leather Supply Chain Conference, held ahead of APLF 2026. Seven presentations across one afternoon. Seven perspectives on where the industry stands and what it needs to do next.
What follows is a summary of what was said, what it means, and what the themes running through the day tell us about where the industry is heading.
The conversation the industry is having with itself
The programme was broad on paper. Ranging from sustainability science to craft tradition, then foraying into future focussed themes like digital twins and a live rollout of AI grading at scale. Unpacking traceability standards and what vocational education could mean for the industry, it all culminated in a tanner's call to arms on circular economy.
What was striking, sitting across all of it, was how much the speakers were circling the same problems from different angles, often without knowing it. Three threads ran through almost every session.
First: leather's value is real, but the industry is losing the argument about it. Second: it’s becoming increasingly glaring that technology is not the obstacle. The obstacle is pace, alignment, and will. Third: quality data, traceability, and sustainability measurement are not actually separate projects.
Leather is losing on methodology, not merit
Federico Brugnoli, Founder and CEO of SPIN360, now part of Bureau Veritas, opened with a question that carried weight well beyond LCA science: when leather shoes and synthetic shoes are evaluated using the same default assumption of 100 wears, what does that do to leather's environmental case?
The short answer is damage. Not because leather is worse, but because the measurement framework is wrong. A leather shoe is typically worn far more than 100 times. The current European standard does not account for this. Under current methodology, standard bovine leather sits at 85 kg CO2 equivalent per kilogram of material. PVC leather is measured at 2.7 kg. Federico's point was not that leather is worse. It is that those numbers are not an honest comparison.
The structural problem is allocation. Leather is asked to trace back to the birth of the animal. Synthetics trace back to the polymerisation plant, not the oil drill. The prospection emissions and full refinery output of petroleum-based materials are simply not in the calculation. And leather carries the full burden of cattle, including the farming emissions that exist regardless of whether the hide is used or discarded.
His Argentine case study was the session's most concrete moment. A farm operating on regenerative agriculture principles produced hides whose verified LCA score came in below all synthetic alternatives. Five independent reviewers signed off on the report. Under current European methodology, that result is invisible.
"Brands should use direct metrics and work with primary data. There is a very important opportunity here speaking about durability and useful life."
Federico Brugnoli, SPIN360
Barbara Mannucci, Director of the Consorzio Vera Pelle Italiana Conciata al Vegetale, made a related point from a different direction. Twenty samples of vegetable-tanned leather from consortium tanneries all exceeded 80 percent organic biogenic carbon content. The EU Green Deal target for 2050 is 80 percent. Many alternatives marketed as sustainable reach 25 to 30 percent. The gap is real but most designers specifying materials are unaware.
Burak Uyguner, third-generation tanner and President of the International Council of Tanners, said it most plainly. The industry is not struggling because leather is a bad product. It is struggling because the industry has failed to explain its value. Thousands of small players with no unified strategy. A sustainability narrative losing ground to alternatives that do not hold up under scrutiny. The science is there, but the will to engage where the argument is actually being won and lost is not.
"The future of leather will not be decided in fashion shows. It will be decided in how intelligently we use the entire animal resource."
Burak Uyguner, Uyguner Deri Group
Federico's ask was simple: be in the room where the science is being built. Leather has the substance. The frameworks and the communication are failing it.
Technology is not the obstacle
Four separate sessions, approached from entirely different starting points, arrived at the same conclusion. The tools exist. Industry readiness is the bottleneck.
Dr Geoff Holmes Director of LASRA, brought 38 years of leather technology experience to a session on digital twins for the tannery drum. A drum is a coupled system. Temperature, pH, concentration, and mechanical action all interact. Technicians develop intuition for this over years, but intuition does not scale across multiple drums running simultaneously, and it leaves when the technician does.
Digital twins encode that judgment and make it available everywhere. The science behind hide cooling models, salting penetration estimates, and chrome fixation prediction has been understood for decades. What changed is the ability to put it into practice. Any technician could build these tools today using generative AI. The question was never capability. It is whether the industry will move.
"The drum remains exactly what it has always been. What's new is that we can finally see inside it while the process is still running."
Dr Geoff Holmes, LASRA
Vita Kobiela, Communications and Projects Manager at Cotance, presented the Metaskills for TCLF project: a four-year, four-million euro EU-funded initiative producing:
- 36 micro-courses across eleven European states,
- Each accompanied by 360-degree video shot inside real tanneries, and,
- Twelve metaverse labs enabling students to walk through a tannery without leaving the classroom.
Courses pilot in September 2026 and the open platform follows in 2027. The question now is, will the industry commit to using it?
Deborah Taylor, Founder and Managing Director of the Sustainable Leather Foundation, presented the outcome of two and a half years of work through the Traceability Cluster, bringing four major certification bodies to agree on a common minimum standard for traceability. The structure that emerged is three levels, from basic documentation any organisation already holds up through EUDR geo-referencing and sustainability certification. What made this hard was not the technology. It was the alignment.
"It doesn't matter where you are internationally. We can find a methodology that can work whether you are in a highly industrialised area or a very low-technology area. But we need to keep harmonising."
Deborah Taylor, Sustainable Leather Foundation
The Mindhive-JBS Couros panel, between Sergio Sfreddo, Head of Global Quality at JBS Couros, and Ray Connor, COO of Mindhive Global, made this most concrete. JBS runs 21 production units with 7,000 employees across four continents. Ten wet-blue sites in Brazil, multiple shifts, twenty to thirty graders per site applying a judgment that is subjective by nature. Hides pre-selected at wet-blue still had to be re-inspected before order allocation. Cost in time, labour, and quality giveaway.
The technology worked. All ten sites were live by December 2025. Anticipated grader resistance did not materialise because their roles shifted rather than contracted. Phase two, now underway, uses the grading data to drive allocation and order fulfillment directly.
What made it work was the design phase. Mindhive initially spent time understanding the business. The defect catalogue grew from 16 classes to more than 30, and regional variation within Brazil meant each site needed its own calibration. The implementation succeeded because the partnership was right. The technology was ready long before the rollout started.
"The sooner you start, the sooner you're going to realise the value. Sitting on the fence and thinking how does technology apply is one approach. But the sooner we embrace and adopt the new tools and the new ways of working, the sooner we can unlock the value."
Ray Connor, Mindhive Global
Quality data is the foundation for everything else
This is the thread that connects the other two. The arguments about methodology and the arguments about readiness both eventually arrive at the same structural problem: without accurate, consistent data at the foundation, the claims and the systems built on top of it do not hold.
Sustainability claims require defensible data. Federico's regenerative agriculture case study produced a below-synthetic LCA score because the data was primary, verifiable, and independently reviewed. Without that, it is just a claim. Under increasing regulatory scrutiny, claims without evidence will not survive.
Traceability standards require data integrity at every step. Deborah's harmonized framework is structurally sound. But a traceability system is only as useful as the quality of the data flowing through it. A system that tracks a hide from farm to finished leather means nothing if the quality record at each stage is inconsistent or contested.
The JBS example is the clearest demonstration of what verified quality data makes possible over time. Standardizing grading consistency, and creating a hide-level digital quality record, was the foundation. What it unlocks is where the value is: getting the right hide to the right order, cross-site allocation, lead times reduced, grading criteria refined continuously as patterns emerge. None of that works without consistent verified data underneath it. The grading is not the end point. It is what everything downstream depends on.
"The final goal is to bring value to the whole chain, not only to JBS, to our customers mainly."
Sergio Sfreddo, JBS Couros
Traceability claims, sustainability arguments, and operational optimisation all depend on the same foundation. Without quality data at every stage, none of it holds.
What the day added up to
Seven sessions, one consistent undertow.
Leather has real advantages: it’s durable, traceable, biogenic, and a byproduct of food production. The science supports these claims when done honestly. But the evidence is fragmented, the measurement frameworks are working against the industry, and the communication has not kept pace with the challenge.
Digital twins do not replace technician knowledge, they extend it. AI grading does not replace graders, it elevates them. Traceability systems do not solve sustainability. They are the foundation on which sustainability claims can be built and verified. These are not separate projects. They are the same project, approached from different angles.
The question for every operator is not whether the tools are ready. The question is how long they can afford to wait.
And when you are ready to move, the technology is only part of it. You need partners who will invest in understanding your business.
