The publishing industry is undergoing a massive transformation to be more environmentally conscious. Driven by these initiatives, publishers are meticulously examining every step of their supply chain. We’ve seen an increase in the use of FSC-certified paper and vegetable-based inks.
However, there is one element of bookbinding that is missing in these discussions: the glue.
While the pages of the book might be inherently green, the adhesive is often overlooked and decidedly not environmentally friendly. If publishers really wish to push forward a green initiative, they have to look at the adhesives as well as the larger book components. Switching to natural, plastic-free adhesives now offers publishers an efficient, budget-friendly path to achieving their sustainability goals.
In this article, we will break down:
- The issue with traditional glues when it comes to sustainability.
- Alternatives to the traditional, giving publishers safer options.
- How to put eco-friendly adhesives into your process to make a successful leap to be more green.
- How LD Davis can help you make these changes and remain sustainable.
The hidden problem with traditional glues
The binding industry has relied heavily on synthetic adhesives, primarily Ethylene Vinyl Acetate (EVA) and Polyurethane Reactive (PUR) glues, for decades. And while they offer strong bonds, these adhesives are derived from petrochemicals, meaning they are liquid plastics.
When a book bound with traditional synthetic glue reaches the end of its lifecycle and heads to a recycling facility, these plastic polymers create significant hurdles. During the repulping process, where paper is broken down in water, synthetic glues do not dissolve. Instead, they break into tiny fragments known in the recycling industry as stickies.
These microplastics clog recycling machinery, contaminate new paper products, and ultimately result in a lower yield of recycled paper. Basically, conventional adhesives disrupt the circular economy, keeping books from being 100% recyclable.
Plastic-free book glue
The solution to the aforementioned stickies problem lies in a return to nature. Long before synthetic polymers dominated the market, bookbinders relied on natural, organic materials. Now, modern science has optimized these natural ingredients to create plastic-free book glue.
At LD Davis, our eco-friendly adhesives are formulated from natural, renewable resources such as protein (gelatin) and starches. Because these materials are organically derived, they are completely biodegradable and non-toxic. More importantly, protein and starch-based adhesives are entirely repulpable.
When a book bound with LD Davis eco-friendly glue is recycled, the adhesive breaks down naturally in the repulping water. This means it cleanly separates from the paper fibers without leaving harmful microplastics behind. By making this simple switch, publishers can ensure their books are truly and completely recyclable from cover to cover.
Achieving your eco-friendly publishing goals
Most modern publishers are setting aggressive ESG (Environmental, Social, and Governance) goals. Every material choice matters when it comes to reducing our carbon footprint to eliminating single-use plastics and beyond.
Switching your adhesive is a seamless way to accelerate your progress toward these eco-friendly publishing goals. Unlike overhauling heavy printing machinery or sourcing entirely new distribution networks, changing your adhesive is a highly actionable, plug-and-play solution. It immediately reduces the plastic footprint of your product line.
Today's readers are actively seeking out brands that align with their values. Proudly marketing your books as 100% plastic-free and fully recyclable provides a significant competitive edge in a crowded, environmentally aware marketplace.
Cost-effective sustainability
One of the most persistent myths in manufacturing is that sustainable alternatives are inherently more expensive. When it comes to natural bookbinding adhesives, this couldn't be further from the truth. Eco-friendly glues offer distinct operational advantages that can significantly lower your total cost of production.
First, protein-based adhesives typically run at lower temperatures than synthetic hot melts like EVA or PUR. Lower application temperatures mean less energy consumption on the production floor, directly translating to reduced utility bills. Second, because natural glues are water-soluble, cleanup is vastly easier and safer. There is no need for harsh, expensive chemical solvents to clean your machinery.
Finally, natural adhesives are notoriously gentle on application equipment. Synthetic glues, particularly PUR, require specialized, costly equipment and can cause rapid wear and tear on machine parts if not maintained perfectly.
In contrast, protein glues run cleanly and consistently, reducing machine downtime and lowering maintenance costs over time. When you factor in the energy savings, reduced maintenance, and eliminated need for toxic solvents, eco-friendly adhesives prove to be highly cost-effective solutions for large-scale operations.
Driving sustainable book manufacturing forward
The future of the publishing industry relies on sustainable book manufacturing. As extended producer responsibility laws become more stringent globally, publishers will increasingly be held accountable for the end-of-life impact of their products. Creating a circular economy, where every part of a book can be safely returned to the earth or reused in new products, is no longer just a noble ideal; it is a business necessity.
Adhesives may only make up a tiny percentage of a book's total weight, but they have an outsized impact on that book's environmental footprint. By choosing natural, bio-based glues, publishers can remove the last barrier to true sustainability. They can ensure that the knowledge and stories printed on the pages are the only things that last forever.
