If repair culture, more intelligent waste management, and shifting the status quo away from mass-consumerism is something you might wish to support then consider donating to one of the following: The Restart Project, Extinction Rebellion, Precious Plastic, the Fablab Foundation, or the Repair Cafe community.
You might also consider exploring some of these resources and communities: the advocacy group Repair.org, the free online repair manual iFixit, this lovely podcast (listed above as well)The Restart Project, these two repair-focused events Maintenance Festival and 4S, this online research community Discard Studies or this artist working with discarded mechanical parts, Aleksandar Petrovic.
