Starch is a natural polymer found in many processes either as an adhesive or a thickener. Following paper production, corrugated board is the second largest application of non-food starches globally, where it it used as an adhesive between the fluting and liners. The control of the adhesive viscosity during process and storage is critical. However, despite further developments regarding the formulation of starch adhesives, the viscosity is commonly not stable enough over extended periods of time, in particular over weekend storage. In this first of a series of blog posts with the corrugated boards application as the example, I will give an introduction to this problem, and the new technology of Exilva, a microfibrillated cellulose, to solve it.Read more
Sustainability is a widely used concept, but it is critical to understand what it means and that it is more than just a bunch of production data or a waste reduction plan. Cradle-to-cradle thinking is necessary. The whole life cycle, the production, the use and the disposal of the end product matters.
Microfibrillated cellulose (MFC) is based on one of the most abundant natural resources on earth. Cellulose, the raw material for MFC, is the main structural component in all plants. Its versatility in both sourcing and use gives a perfect opportunity to create new and exciting solutions. To understand the perspective of sustainability and MFC, I will put cradle-to-cradle thinking in the setting of life cycle assessment (LCA).
Over the last several years consumers have become more and more aware of the environmental impact of cosmetic products. Indeed cosmetic products end up down the drain and in the water system after a shower. The trend today is, therefore, to use natural raw materials to replace synthetic ingredients and reduce the environmental impact.
The challenge for formulators is to find a natural material that performs very well in the different types of cosmetic products. Microfibrillar Cellulose, MFC, an environmentally friendly, sustainable and effective additive, represents a good opportunity to fulfil this requirement. But why is MFC relevant for cosmetics, and where can MFC improve the natural profile of cosmetics and personal care products?
Microfibrillated cellulose (MFC) is subject to high interest from both academia and the industry these days. A lot of exciting research is being conducted at various universities and research centeres around the world. In this blog post I will review articles I found particularly interesting regarding the use of MFC in adhesives and coatings. Note that, for the sake of simplicity, I have used the term “MFC” throughout this text even if the researchers might have used a different name in their articles.
Microfibrillated cellulose (MFC) has potential as a multifunctional additive in various applications. Its performance ranges from improving stability and flow properties in coatings and adhesives to giving immediate anti-wrinkle effect in skin creams. We often say that, in addition to these effects, one of the other advantages of using MFC is that it is “readily activated”. But what does that mean?
In the exiting field of microfibrillated cellulose new usage opportunities are constantly emerging. During the first quarter of 2016, we have seen many interesting new usage areas, and I will show you a selection of them in this article.
Microfibrillated cellulose (MFC) is a natural and sustainable material derived from cellulose. As for any process, it is important to have good control of the raw material when producing MFC. For cellulose, the picture is slightly more complicated since there are many cellulose sources that can be used as raw material, and each of them will lead to different MFC qualities. In this blog post I will introduce you to different raw materials, how the processing of the different raw materials can affect the MFC quality and how to deal with the natural variations in the raw material.
Since around year 2000, there has been a notable increase in the number of patent applications filed regarding new MFC materials, new processes for production and new application areas for MFC. The nomenclature used in the field of MFC varies (nanocellulose, cellulose nanofibers, nanocellulosic fibers etc). In this blog post, I will give you a summary of a few interesting patent applications recently published, using the “original” nomenclature MicroFibrillated Cellulose (MFC).
Currently the world financial situation is such that expensive exploration for new oil wells becomes less and less tempting. The successful oil business today is rather driven by the necessity to extract more oil out of any existing oil well, than previously considered desirable or indeed possible.
The various techniques to achieve this are called Enhanced Oil Recovery (EOR). Common for most EOR is some form of liquid or gaseous injection into the well under high pressure. The objective being to force more oil out of the reservoirs for collection.
