Artist Patrick Cikuru Cirimwami's goal is bigger than helping clean up discarded plastic.
He will melt down the plastic to make a thick liquid which he uses to paint portraits of politicians - intended to be a condemnation of what he says is their inaction in protecting the environment.
Last month, the artist's portraits of political figures, from independence leader Patrice Lumumba to current president Felix Tshisekedi, were displayed at a cultural center in his hometown, Bukavu.
"There have been many conferences in DRC, many meetings ... but we have not taken measures to protect nature. As a Congolese artist, I can send a message," said the 26-year-old.
DRC, like other African nations, has insisted on its right to develop its economy by exploiting its vast natural resources. It has come under criticism for putting oil blocks up for auction in the world's second-biggest rainforest.
It has pledged to minimise the potentially devastating impact by using modern drilling methods and tight regulation. It also hosted talks before November's COP 27 climate summit to call on rich nations to honor a pledge to developing nations to ensure fair finance to fight climate change.
