Sustainable Products, Projects and Green Design Plastex Eco-friendly Material by Reform Studio Grammy’s chairs incorporate our new designed handmade fabric, the new edition. Plastex#9. An ecofriendly material, translates the need for environmental sustainability where wasted plastic bags play an essential role in design. It’s designed to raise awareness about the sustainable change in our world today and to revive the craft of weaving by empowering local communities. Plastex#9 is made from reused plastic bags and cotton threads. Plastic bags are collected, sterilized and cut into thin stripes that are interwoven on a manual handloom. The fabric is durable, strong and water-resistant.
