The scientific method Life Cycle Assessment (LCA) is a tool originally developed to scrutinize the environmental performance of products, product systems or services. In recent years, the LCA framework has been expanded to include all aspects of sustainability. This blog post will present what LCA is, how it has developed historically and why you should care about it.
Solving problems you have or initiate new innovations can lead down quite different paths. Sometimes the urge to get rid of a problem can lead to many quick decisions, but what should one really look for in these types of situations? Should your standard tool box of problem solvers be used, or do you have the opportunity to focus on upgrading this box? In this blog post, I will try to show you some concrete examples why adding new tools to your tool box can improve your functionalities beyond your scope, using the microfibrillated cellulose as an example. Simply, why new functionality beats substitution.
Coating performance is often very complex, and can depend on the coating system itself, substrate to be coated, conditions during coating etc. Increasing the performance is often a lengthy process with multiple tests on wet paint performance and dried coating performance. Key aspects of wet paints can be control of rheology, and for solid coatings the ability to improve endurance. Are there technologies available for aiding on the key aspects? For sure. Are there new sustainable additives which can improve the new water borne technologies? Let me show you an example of exactly that in this blog post.
You may have noticed that the number of waterborne systems has increased massively during the past decade. Waterborne systems, like paint and adhesives, where water is the main part of the product in many cases, are popular due to several factors. My goal with this article is to introduce you to what I believe are the three most significant aspects of the increased demand for waterborne product systems, focusing on coatings and adhesives.
Rheology is the study of deformation and flow of material under stress, for example how easily material changes its form when it is pressed, or how easy it is to pump liquid in the pipes. Yield stress and viscosity are two importance aspects in the study of rheology and I will today exemplify this by using the cellulose fibrils/nanocellulose technology.
Concrete products are a complex mixture of chemicals, fines, and heavy particles. It's always challenging to control the stability, flow and strength of it. Many admixtures have been created to overcome these challenges, often containing synthetically derived performance additives. I will here try to give you some input of one of the new technologies and how it affects various parameters in the concrete.
For decades, producers of fluid materials have used HASE as the fundamental technology to control flow. How can new technologies complement this work horse of rheology modification? This week I am trying to uncover the key aspects of the HASE technology and give you ideas on the HASE technology in relation to the world I am familiar with: nanocellulose and cellulose fibrils.
As a researcher, to have an overview of the alternatives available in your area of profession is of importance. In the landscape of rheology, new alternatives are emerging. In my short review today, I will grasp on the subject of similarities and potential synergies between two of the candidates you should note down: nanocellulose and hydrophobically modified ethoxylated polyurethanes (HEUR). Here are my hints and tips on how to understand these two technologies better.
There is a growing interest to increase the portion of bio-based components in various consumables. We have previously discussed about the challenges to incorporate microfibrillated cellulose (MFC) into composite materials with hydrophobic matrixes, such as PLA. Today we will take a step even further and see how cellulose fibrils can support the development of more environmentally friendly tires with high performance and durability.
There are several solutions to improve strength performance, and there are new materials available on the market. But how do you find the reinforcement additives and agents that provides the benefits you are looking for? And can this be done inline with the increased demand for sustainability at the same time? Spend a couple of minutes on this weeks blog post, and get some inputs and ideas on what to expect from one of these new materials.
