The leather industry has, for decades, been at the forefront of innovation in sustainable technologies. It has helped manufacturers reduce their carbon footprint, but also produce leathers that are eco-friendlier produced and free of VOCs. Yet, the public image of tanneries is often very different.

When you think of a leather tannery, you are likely to have an image in your mind of an open pit filled with liquid. Hides are hanging from racks around these as workers in shorts and t-shirts handle the substances used to produce leather. And that’s as far from the truth as it gets in how leather today is produced in safe, state-of-the-art facilities, yet for unclear reasons, media reports keep featuring pictures of tourist attractions or third-world facilities. Let’s see what a modern tannery looks like.

Watch the animation below:

Especially today, with growing meat consumption and a limited availability of resources, reusing materials we have in a safe and controlled manner, is vital. Animal hide are leftover in abundance and modern tanneries turn this by-product into quality leathers with minimal impact.

Leather Naturally recently published an article asking «Is leather sustainable?» and tries to answer the question.

In their opinion, the answer is clear: yes. If sustainable means converting materials that would be otherwise thrown away to make the products we use to live, keeping things for a long time, repairing them when we need to, passing them on to someone else to use after us and, eventually, recycling the product as many times as possible. Leather is most certainly sustainable.

And the leather industry is also an excellent example of the circular economy, as set out by the European Commission in December 2019, its sustainable consumption and production support the United Nations’ Sustainable Development Goals.

Leather’s durability, longevity and recyclability as a natural product are underpinned by regulations and quality standards in many countries to ensure that sustainability credentials are met and maintained throughout its production.

Responsible tanneries are also very transparent about their compliance data and openly share the following areas of information with their customers: how they comply with environmental controls, how they manage wastewater and other waste, how they use and manage chemicals including restricted substances, how tanneries keep their leather workers safe, how they calculate how much energy and water they use and how customers can track a leather supply chain.

Tanneries like Splenda Leather are firmly committed to these principles of responsibility, sustainability and transparency. We are very sure that the tanning industry has come a long way in recent years and, with everyone’s commitment, we hope that in a few more years we will be appreciated as a benchmark of a sustainable productive sector worldwide.

A residue from the extraction of olive oil called bagasse contains tannins that allow the leather to tan naturally, reducing the use of chemicals in the process. This is confirmed by a recent investigation by the A3 Leather Innovation Center Chair, of the Igualada-UdL University Campus, specialized in the leather production chain. The Olipo Project will facilitate the production of leather goods that are more ecological and free of contaminants such as chromium.

This research not only makes the leather industry more sustainable but also contributes to highlighting a residue from the oil extraction industry. According to the director of A3 Leather Innovation Center, Anna Bacardit, the use of bagasse «allows us to obtain top quality ecological leather, while revaluing a problematic waste from the olive oil extraction industry».

Of the total material that is provided for olive production, only 20 percent is the final squeezed product and the remaining 80 percent is bagasse, that is, the remains of husk, bones and other residues of the raw material. Thus, the Olipo Project proposes new strategies within the framework of the circular economy, establishing synergies between the two industries.

More than 17 million tonnes of animal elements, derived from leather tanning, are processed every year across Europe, producing just under 3 million tonnes of animal fat.

Part of all this fat is solely destined for disposal in landfills or incineration, which is a problem for both the climate and the environment as it may contain harmful substances.

To give a new life to this element, the new Life Superbiodiesel project offers an alternative for the recovery of these wastes and aims to develop, test and demonstrate the production of biodiesel from animal waste using a new fat transesterification technology.

The Technological Institute AIJU coordinates this project that aims to design, build and optimize a pilot plant capable of processing five tons of biodiesel obtained from animal fat. One of the advantages of this project, in addition to the production of high added value biodiesel, is the potential reduction of 80 percent of the carbon footprint over conventional diesels and 35 percent compared to first generation biodiesel, according to first estimates.
