This question refers to the CNN Heroes list which is a choice of everyday people doing some extraordinary things in helping solve some of the world's biggest problems. One of such people is Samir Lakhani from the recycling soap bars project.
Recycling hotel soap bars is a project that organizes collecting of used soap bars, which would've been thrown away, processes and sterilize them in order to deliver them to the developing countries in order to improve hygiene and prevent some of the diseases.
