Background information

Ferreira do Alentejo is the capital of Olive Oil Production in Portugal. For the past 10 years many farmers have been planting monoculture super intensive olive tree groves (olivais super intensivos). And now all these trees are reaching their full production. This leads to a situation that is not sustainable for the region. Since there is a huge amount of olive pomace (bagaço da azeitona) that is just being incinerated. This incineration creates a lot of undesirable gases that spread for many Km and negatively affect the life of many people.

There are at least three factories working (Fortes, Aggraria, Alvito) and you can see some media buzz: 1. www.pan.com.pt/em-fortes-novos-vive-se-com-o-lixo-do-lixo/ 2. www.sulinformacao.pt/2018/06/qualidade-do-ar-junto-as-fabricas-de-bagaco-de-azeitona-de-ferreira-e-alvito-deve-ser-monitorizada/ 3. https://diariodoalentejo.pt/pt/noticias/10082/poluicao-das-fabricas-de-bagaco-voltou-ao-parlamento.aspx

Olive pomace (bagaço da azeitona) is just being burnt because it’s the easy way to deal with it. But there are many other options than can be much more sustainable and circular and that can be of economic interest also.

The Take-Back Challenge

Challenger:

United to Remake X Re:Costura

Theme or sector:

Fashion

Describe the challenge in one sentence or question:

Design a reliable circular process of recovering used clothes.

Define 3-5 components of the challenge:

Poor quality of materials: a big slice of the clothing going to waste is coming from fast fashion. Lack of appropriate selective collection, dismantling processes and used fabric treatment. Having enough of the same material to produce in a medium scale. Making upcycled products appealing to the consumer, since it still carries a lot of stigmas.

Background information In Portugal, around 200 thousand tons of textile waste are thrown away per year. The percentage of waste that is sent for recycling and reuse is still not done under the conditions that it should be. However, the new Directive (EU) 2018/851, published on May 30, 2018, established mandatory deadlines for the selective collection of textile waste to be implemented on January 1, 2025. With the publication of this directive, the implementation of selective collection systems for textile waste is foreseen by the urban waste management systems, or by the municipalities that integrate them. From then on, textiles sent as waste will, whenever possible, be prepared for reuse and recycling. Until now, the upcycling potential of these resources has remained unexplored.

X Setting the challenges for the Hackathon groups is an important first step that will shape the direction of the event. At CESCY we wanted to focus on the main problems for sustainability: Food, Waste and Fashion. From there we connected with companies and organizations that shared their real challenges.
