Coffee is one of the most consumed beverages in the world and the second largest traded commodity after petroleum. As a result of this large market, the reuse of coffee industry residues is of great importance from an environmental and economic point of view. During the roasting of coffee beans, large amounts of coffee silver skin (CS) or chaff, as it is also called, are formed as a by-product.

SDG's
The CS can be used for compost. It is light and airy and has a relatively high nitrogen content. In urban areas, however, the need for compost material is limited and since in many cities, such as Amsterdam, compostable waste still cannot be separated, most of the CS is currently being disposed of as waste. Options for effective and economically viable exploitation of CS need to be developed. The relatively small scale of production in micro-branding companies poses a specific challenge. While the silver skin significantly increases the company’s waste disposal costs, the volumes are not large enough to justify separate collection for low-value use as composting. The intended use must be either in the store or nearby (e.g. baking) or of sufficient quality to justify the costs associated with logistics.

The options for effective and economically viable utilization of coffee silver skin need to be developed.

The intended use must be either in the store or nearby (e.g. baking) or of sufficient quality to justify the costs associated with logistics.
The aim of this project is to provide an overview of the biomass coffee siver skin, its chemical composition and its biological activity to identify viable high performance material applications. The results of this research are used to identify the market opportunities of products based on the high quality components in coffee silver skin. Examples of this can be found in cosmetics and pharmaceuticals.

Martijn Zieverink appointed as professor for the Biobased Transitions Research Group at MNEXT
The year is 2073, and the world runs on 100% sustainable resources and energy sources. The market value of oil giants like Shell and Saudi Aramco has evaporated. What has led to the emergence of companies with a market value of 1,000 billion euros, deriving their value solely from biobased resources? What were the, at the time small, transitions that laid the foundation for overcoming the addiction to fossil resources?

In memoriam: Max Drath
Max was an passionate colleague, full of ideas and enthusiasm. An expert of the outer category. Despite the fact that he had not been involved in the Biobased Construction lectorate for very long, his expertise and friendliness were greatly appreciated by colleagues from day one. Both from hands-on research, as from education and business, everyone knew how to find Max quickly.
