Continuously following the world of cellulose fibrils and the development is both dynamic and interesting. A lot of new inventions are taking place, based on the cellulose fibrils. We have given 3D printing a quite high focus in the last couple of reviews, but this week there are two other news items on the list: composites made from cellulose fibrils. Dig into this week’s research review to find out more on what might possibly be the next generation of composite materials.
The performance coatings sector has seen decades of development to protect installations and transportation equipment. The sector has been highly dominated by solvent based systems and these systems have seen incremental innovations for a long period of time. The end-user demands for these systems have been set in a context of a world in an ever-changing environment: high pressure on efficiency, increased globalization and international trade, as well as the period of increased climate focus. So how is this world going to look in the near future? In my attempt to share thoughts on this subject, I will focus on the rheology system, how its currently being solved and how it can be solved with alternative, more environmentally friendly technologies in the future.
Within the field of nanocellulose and cellulose fibrils, there is an increasingly rapid pace of new developments, where the cellulose fibrils either appear on its own or as a part of an advanced relationship between several performance enhancers. Today I have collected two highly interesting, but very separate news articles for you, but where the common denominator is the ability to retrieve strength and performance from these types of materials. Enjoy!
If you google the word medical device, you will get pictures of sophisticated hospital equipment and diagnostic devices. In practice, a term medical device is wider than just that and covers a range of different kinds of articles, starting from plasters and bandages to endosseous implants and implantable pacemakers, intended to be used for therapeutic purposes of humans or animals. We have previously written about the role of MFC in wound care products and today we are going to take a step deeper to the current status of nanocellulose in medical devices, especially topical and implantable ones.
This week’s blog post started its life when I attended a stakeholder forum which was organized by the Bio-Based Industries Joint Undertaking (BBIJU), a part of the EU H2020 initiative. I listened to a high number of innovators within several fields such as bio-fuels, bio-chemicals, as well as new and more sustainable materials. I started a line of thought, where the word paradigm occurred to me; I am part of a generation raised in the latter part of the 20th century where a majority of things we take for granted are based on technologies from the petroleum sector. The paradigm has given opportunities and challenges, but how does this paradigm affect us and our thoughts on innovation?
Plastic microparticles found in the environment have gotten a lot of attention lately. Many of the plastics are very durable and do not degrade in a reasonable time in the nature, although today there are also biodegradable plastics available. Small pieces of plastic can be found almost everywhere on the Earth and it is not fully understood what kind of consequences that could have for the human beings and environment. Therefore, replacing non-biodegradable plastics with biodegradable materials in packaging, clothes and cosmetics has high focus right now. Cellulose fibrils come from wood or other natural resources; are they biodegradable? Can they replace non-biodegradable plastic and reduce the amount of microplastics in the environment?
