There is a win win solution for grocery plastic bags and people! It is making sleeping mats or pillows out of plastic bags for homeless. Beside a project named Plasticbagmats, people around the world are performing this individually. In this project people volunteer to help collect the bags, cut them, loop cut bags together and roll them and making mats by looming or crocheting. Approximately 350 plastic bags are required to make a mat by volunteers which will take about 3-4 hours.
