Stabilisation of biological formulations in agriculture

16. November 2021

The last few years have seen a very fast increase in the use of biologicals and biocontrol agents in crop protection and agricultural products as part of the shift towards more sustainable and environmentally friendly agriculture.

Biodegradability of cellulose fibrils

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?

[VIDEO] Topic Tuesday: Dispersion and Tip Speed

Welcome to the first of our brand new video series; Topic Tuesday, brought to you by the Exilva Blog. Topic Tuesday is dedicated to one specific topic, providing you with information on cellulose fibrils straight from the top of our head. We'll kick it all of with a discussion about the importance of correct dispersion and how the effect of tip speed affects the end result.

Dispersion of Microfibrillated cellulose – a critical success factor

Traveling around talking about microfibrillated cellulose for the past 8 years, has thought me an important lesson; always make sure that people understand how to disperse the fibrils sufficiently. This is really the main factor in gaining the key functionalities from the product. So how can you make sure that you are getting the most out of the cellulose fibrils when you are using it in your formulation? In this article I will give you some guidance and video tool on to how to get this right from the start.

Can cellulose fibrils increase your factory's productivity?

As a new boy in the world of cellulose fibrils, I am steadily getting an overview of what potential users of cellulose fibrils are interested in. The unique combination of properties that cellulose fibrils has is the obvious point most are interested in. In addition, the natural and renewable aspect to the material and the possibility to replace oil-based chemicals is becoming more and more important. But could there be more than that?

Why sustainable innovations will make our planet healthier; our globe is changing

2017 has been a year of record storms and hurricanes. In August and September, the hurricanes lined up in the Atlantic and entered into populated areas one after another. The National Oceanic and Atmospheric Administration (NOAA) in the US reports that the statistics show an upward trend, also correlating to the size and magnitude of these hurricanes. The statistical data show uncertainties during the period from 1880s to 2016, but NOAA believes that the trend (based on research) shows a significant increase both in frequency and magnitude going forward. Why do I start my blog post on a nanocellulose blog with this? Well, because the link NOAA put between the Atlantic hurricane trends and global warming is obvious.

Nanocellulose Research Review: Commercial update Sept. 2017

The field of nanocellulose, fibrils of cellulose and microfibrillated cellulose is moving rapidly in the direction of full commercialization. Still, there are many undescribed application areas that are appearing, with higher and lower levels of innovation. In this week’s review, I am covering two very interesting stories; the increased interest from Japanese motor industry in utilizing the nanocellulose as components for their vehicles, and 3D printing of a nanocellulose alginate product.

Surfactants – a tool to tailor surface chemistry of MFC?

One of the advantages of cellulosic materials (including nanocellulose and microfibrillated cellulose (MFC)) compared to synthetic materials, is their environmentally friendly profile as well as their biodegradability. This profile is impacted by the number of chemical reactions the product will undergo during the manufacturing process. It would therefore be favorable to obtain desired chemical properties via physical adsorption instead of chemical reactions.

In this blog post, you will find examples on possible effects of surface adsorbed surfactants on cellulosic materials.

3 things to remember when using MFC in the lab

Introducing a totally new material or technology to the market can often be challenging. Most people tend to have their favorite products which they know and prefer to work with. The natural way of testing of a new material is to compare it with the current products and apply the existing working routines to the first test runs. In some cases this approach might work but unfortunately in many cases it leads to a failure.

Today we will discuss about the important things that you should keep in mind when taking the first steps into the world of microfibrillated cellulose (MFC) and tell you how to gain the full potential out of it.

The future of Aerospace, and its demand for new materials

Innovation in aerospace technologies is moving forward with a very high pace. Since the mid-1990s we have seen the birth of much more energy efficient propulsion systems, increased use of advanced materials like carbon fiber, a higher level of adhesives used and improved customer experience through noise reduction. So what’s next on the agenda for all the companies involved? Can we continue to improve the materials or have we started to reach the end of optimization? And are there any new materials coming that could be part of changing the game yet again?

Intimate relationships – cellulose and epoxy

Professor Lars Berglund, Head of the Biocomposites Division at KTH Royal Institute of Technology in Stockholm (Sweden), guides us through the relationship between cellulose and epoxy in this blog post. Not only do they matter, the properties created by this reaction are also excellent. Learn more about this in this weeks guest blog post.
