Collserola wool will not be thrown away is the result and implementation of the research carried out by ERTE Catalyst.

It is a booklet that includes six cards dealing with: uses that can be given to the wool, information about where to find wool in Collserola (Barcelona), its fair price, indications about its transport, advice on how to wash it and – last but not least– details about those who provided to us the information contained in the cards.

During the period July 2021-December 2022, the ERTE Catalyst work group, structured around the thematic axis ‘New economies and forms of sustainability’, has explored other kinds of economy that put sustainability of lives and environments at the centre. The work group has focused on the livestock context of the suburban area of Collserola, and has allied itself with the interest in the Collserola wool shared with a number of artistic and social collectives. It has taken an interest in the production-distribution-use circuits able to turn residue and waste into possibilities.


This booklet comes from a discovery: the wool from the sheep of Collserola is actually thrown away. It also comes from the will to transform research that has been carried out into a tool that can be put into practice responding to a real need. We want to use it to socialise and share the information we found about wool, so that it can be used to activate relationship networks and uses of material that is currently being discarded.

The booklet has been possible thanks to the trust and involvement of a number of individuals linked to livestock farming, agroecology and the ustilisation of wool – Damià Gibernet, Zaira Arlandi, Josep Montoya, Isabella Rengifo, Vanessa Freixa, Anna Salvat, Ana Vivero and Martina Manyà, Projecte Greta, Josep Bunyesc and Alimentem Collserola.

Collserola wool will not be thrown away has been printed in an edition of 200 copies, which have been distributed with the help of the ethical courier cooperative Les Mercedes in different spaces in and around Barcelona, such as civic centres, cooperatives, organisations and projects linked to agroecology and sustainability, brands whose production is made with wool, wool shops, cultural spaces, art and design centres, training and educational centres in the field of arts and design, professional private agents interested in the information shared in this booklet, and other diverse allies from beyond the Catalan context.
