The Museum of Feelings doesn't really have “exhibits" in the conventional sense; rather, visitors move from one themed alcove to another, five in total, each with its own distinctive aroma. The “Optimistic Room," bathed in vivid pink and purple light, is little more than a lightshow, with patrons using small reflective panels to bounce light around the room.

A woman poses for a picture as bunches of paprika hang on the walls of her house to dry in the village of Donja Lakosnica, Serbia October 6, 2016. Donja Lokosnica is the Serbian “capital of paprika”, since almost all of the 1300 inhabitants are involved in growing paprika. As autumn approaches, the whole village turns red, because of many threads of dried peppers, that hang around Lokosnica, waiting for their winter use. Each of these paprika threads is handmade, still dried according to traditional techniques, assisted solely by the sun and fresh air. (Photo by Marko Djurica/Reuters)

Sustainable development goal target 12.5 is to reduce waste. But with a planet increasingly dependent on technology, is that even possible? As of today, over 30m tonnes of electronic waste has been thrown out so far this year, according to the World Counts.
