From bean to Crush Coffee

Our Crush Story continues, dedicated to the alternative ingredients which are used to produce Crush and which follow the principles of the circular economy. Today we tell the life cycle of coffee and the industrial symbiosis created to gain value from the silverskin, one of the coffee processing wastes destined for landfill.

Industrial symbiosis is a subset of industrial ecology, it describes how a network of diverse organizations can foster eco-innovation and long-term culture change. In which they create and share mutually profitable transactions – and improve business and technical processes in order to maximize the reuse of resources normally considered waste. These resources include material resources (waste and products), energy, services and skills. [1]

The coffee market is one of the most buoyant in the world with an annual consumption at around 9.5 million tonnes (2017 data). Just in Italy, each person consumes an average of 3.4 kg per year and as a country is the fourth largest importer worldwide.

The different phases of coffee processing generate a variety of types as well as a considerable quantity of waste, including 7,500 tonnes per year in Italy of type known as silverskin. The presence of these residual materials which represent a problem for producers, can now become an opportunity for the economy and the environment. How?

Let’s find out together through the coffee life cycle, from bean to Crush Coffee paper.

Crush Coffee Story: a story of industrial symbiosis from coffee to paper

Coffee processing involves different phases that generate a large volume of residue: remnants such as the pericarp to the parchment and from the silverskin to the extraction residues. They are all by-products that could be used for different purposes, instead of being disposed and becoming a waste issue for coffee producers.

It is from here that the idea comes of converting a linear process into a circular one: the coffee waste becomes a renewable and natural resource to produce the high quality ecological Crush Coffee paper.

At the start it is the coffee harvesting which is one of the most important phases as it determines the quality of the product. The berries are picked and in the de-fruiting phase, they are separated into fruit and seed. The bean remains protected by a layer of parchment and silverskin.

Then, coffee is washed, dried and brushed to remove the parchment.

Favini uses the silverskin in a circular economy perspective to produce high quality ecological paper.

Up to this stage, the coffee beans are green and then they are roasted. During this roasting phase the silverskin separates from the coffee bean and it is at this point that it takes on its typical intense brown colour. The roasted bean is then ground and distributed to coffee shops and supermarkets around the world.

Favini has found a way to recover the silverskin and raise this waste material into a valuable raw material for the production of high quality ecological paper Crush Coffee.

Crush Caffè è la carta ecosostenibile ideata da Favini prodotta a partire dai sottoprodotti di lavorazione del caffè.

Crush Coffee is the eco-sustainable paper created by Favini and produced from the by-products of coffee processing.

The silverskin is micronized and added to the mix of ingredients for paper production, replacing 15% of tree cellulose.

At this point the Crush paper can be used and converted to produce various applications such as luxury packaging and catalogues, brand collateral, labels, invitations and notebooks.

I packaging di Lumilalì sono realizzati con la carta ecologica Crush Caffè prodotta a partire da sottoprodotti agroindustriali.

Lumilali’s packaging is made using the ecological paper Crush Coffee produced from agri-industrial by-products.

The products, such as Crush Coffee paper, are recyclable: after their use, they enter into the paper and cardboard recycling cycle, an important system to save energy and natural resources that is promoted every year in Italy by Comieco with the occasion of Month of recycling.

The CirCo project to study and reuse the silverskin

Favini continues its research to find alternative uses for coffee by-products. Together with CNR, University of Milan, the cosmetics manufacturer Intercos and Eurac Research, they have launched an integrated research project on industrial biotechnology and bioeconomy and with a particular focus, on the possible reuse of silverskin.

The CirCo – acronym of Circular Coffee – aims to study the possible increase to value of a coffee by- product deriving from roasting, the silverskin.

Silverskin is a dry waste produced in industrial facilities in the near vicinity, thus making its collection very easy. Silverskin is sometimes used for energy production, but in general it is disposed of as waste. CirCO project aims at upgrading coffee silverskin by adding value to all its various components. Indeed, this one by-product could be divided into cellulose, lignin, lipids and some phenolic compounds.

The cellulose extracted from the silverskin can be used for the production of high-quality papers, while the polyphenolic substances extracted from silverskin (i.e. chlorogenic acid) can be used as an anti-age and anti-pollution ingredient in the preparation of cosmetic products.
