[1/5] Women waste pickers from the city of La Paz pose near the musicians of the Paraguayan Cateura Recycled Instruments Orchestra, at the Sak'a Churu landfill in Alpacoma, in La Paz, Bolivia February 27, 2023.
But the garbage was the point, as the young musicians who make up Paraguay's Cateura orchestra use recycled materials to make their own instruments, "transforming trash into music," according to Fabio Chavez, one of the performers.
"It's very beautiful and I was really surprised with these recycled instruments," said worker Silveria Vega.
The concert played out as local officials in La Paz aim to minimize the environmental impact of garbage dumps, especially the risk they can pose to ground water supplies.
Bolivia's capital produces some 670 tonnes of trash every day, according to official data.
