“…The environmental sustainability of bioadhesive materials and devices is an increasingly important consideration. Researchers developing bioadhesive technologies should aim to minimize their environmental impact throughout their lifecycle, from raw material sourcing to processing to disposal. − This includes minimizing the use of environmentally hazardous reagents when possible and designing products with recyclable or biodegradable materials. , Biointegrated devices have attracted a great deal of interest, but in many cases these devices contain nondegradable electronic materials which can result in waste accumulation and cause environmental pollution. While the wear time of most bioadhesive wearables is relatively short (a day to a couple weeks), their degradation timeline and environmental consequences can be long-lasting.…”

Bioadhesives have emerged as transformative and versatile tools in healthcare, offering the ability to attach tissues with ease and minimal damage. These materials present numerous opportunities for tissue repair and biomedical device integration, creating a broad landscape of applications that have captivated clinical and scientific interest alike. However, fully unlocking their potential requires multifaceted design strategies involving optimal adhesion, suitable biological interactions, and efficient signal communication. In this Review, we delve into these pivotal aspects of bioadhesive design, highlight the latest advances in their biomedical applications, and identify potential opportunities that lie ahead for bioadhesives as multifunctional technology platforms.

Developing polymers with labile bonds has attracted increasing attention since it can favor the chemical recycling into oligomers that could be recovered and re‐used. Different chemical bonds can break upon exposure to external stimuli, such as thermal, UV, or chemical triggers. Among these, the acetal bond can degrade under mild acidic conditions. This study focuses on the synthesis of polymers constituted by acetal moieties suitable for triggered depolymerization. In particular, the solvent‐less polyaddition of 1,4‐butanediol and 1,4‐butanediol divinyl ether was developed and optimized using a heterogeneous catalyst (Amberlyst 15) at 100 °C. The best conditions in terms of catalyst loading and reagent ratio were determined through a Design‐of‐Experiment aiming to achieve high conversion, low polydispersity, and desirable molecular weight. The resulting material presented an amorphous character and thermal stability up to 220 °C. It was confirmed responsive in an acidic environment, being completely hydrolyzed in 42 days, while remaining stable at neutral and basic pH. The obtained results represent a proof of concept for the design of pH‐responsive materials through solventless, and scalable processes. The acetal moiety may be further exploited to achieve architectures presenting a sustainable end‐of‐life by implementing a recycling‐by‐design approach for new adhesives or degradable thermosetting materials.

This paper addresses strengths, weaknesses, opportunities, and threats of the wood adhesives industry as discussed at the International Conference on Wood Adhesives in May 2022. The authors have organized the points made during the discussion and added further facts, assumptions, and conclusions to provide context and perspective, even surpassing the outcome of the discussion. The biggest themes of the discussion were the unprecedented opportunity for adhesives to enable forest products to supply society's surging demand for renewable materials and the challenges in meeting those demands. We see excellent opportunities for wood-based panels and with this, for wood adhesives. The abundant challenges to bio-based adhesives for wood products are highlighted by the large amount of research and commercial effort compared with the small volumes of bio-based adhesives in use. Other threats to the adhesive and bonded products industries include aversion to any chemicals (even stable adhesives), and lack of experienced work force. Wood adhesives underwent significant changes in the past decades, mainly focused on reducing emissions during panel use. Wood use in construction will be boosted by efforts to fulfil the European Green Deal, as implemented in the New European Bauhaus and European Renovation Wave.
