Used items the community saves annually.

Uwaga, Śmieciarka Jedzie is a Polish foundation set out to make one person’s rubbish another person’s find. It began in 2013 as a single Facebook post, became a countrywide grassroots movement, and registered as an NGO in 2022.
The community now runs to more than 870,000 people across over 270 local groups, saving roughly 35,000 tonnes of used items from landfill every year.
With that much traction the foundation needed to scale more cleverly, and to stand on its own platform rather than depend on someone else’s.
The shorter the journey from wanting to give something away to it reaching the group, the better the service works.
Members engage more when they can track what they have contributed, so a counter of items shared and kept out of landfill was a requirement.
A local group that gives away more stays more motivated and more active, and a fundraising call to action gives the NGO something to build on top of the core features.

What we did
The foundation reached Tech to the Rescue and joined a hackathon on using generative AI for social and environmental impact. That is where we picked up the task, and the event became an intensive kick-off.
Item descriptions are generated from images and frequently used phrases, which removes most of the effort in posting something.
Phrases can be stored for future use and post drafts kept, so a member is not starting from a blank field each time.
Seamless integration with Facebook means instant posting where the community already is, rather than asking it to move first.
Both individual and community impact are tracked, which is the part that keeps members coming back. Phase two adds scheduling, collection notifications, safety measures and richer profiles.
Client testimonial
Our community efforts are all about positive impact. Netguru prototyped a GenAI-powered mobile solution within a little over 24 hours – with the MVP we’re now working on, we’re going to be able to monitor our impact. Peter Drucker says that you can't improve what you don't measure. The MVP is the first step to measure our work, so we can scale while maintaining quality, increasing our efficiency, and accessibility. Generative image description also opens up our community to visually impaired users.
