You might have noticed how the air quality around us is changing constantly. Do you remember the last time that you have filled your lungs with fresh and clean air? Every day we are exposed to pollutants in the air we breathe - chemicals as well as fine particles - whether we are staying outdoors or indoors. This problem not only affects the people in developing countries, but the majority of the population on Earth.
Microfibrillated cellulose (MFC) has shown great potential as an oxygen barrier in packaging. This has led to numerous research projects trying to utilize the potential in practice. But how does MFC actually create the barrier towards oxygen?

The biggest change in the coffee culture in recent years has been the way people prepare their coffee at home. An increasing number of households use single serve brewing (pods, capsules) for producing a fresh cup of coffee, resulting in an increased amount of waste. Replacing the current coffee packing materials is not straightforward, and obviously there are several challenges related to it. In this blog post I will play with the idea how microfibrillated cellulose (MFC) could support the development of new, more environmentally friendly, compostable or biodegradable coffee capsules.
