Paint'R is developing sustainable paint packaging to help the professional painter work faster and safer, while saving 75% CO2 emissions and being cheaper for the paint manufactures. Every month up to 1,000,000 paint buckets are thrown out in Denmark. NONE are recycled. Due to an updated EU legislation, paint-suppliers will be economically responsible for the disposal of their packaging in 2025. We have discovered multiple pains in the current outdated design. These include; hard to sort, dispose and recycle, heavy lifting in awkward positions, sharp handles, prone to spillage in cars and while pouring, strenuous to open, not air-tight due to dried paint and many biocides needed to keep the paint fresh. We switch the main material from plastic til reusable cardboard, coming up with a completely new design. A product with better handles, easier to open, faster to set up. It is designed with the professional painter in mind, eliminating the need to pour paint and designed to fit into the use of existing roller buckets. A special opening has been developed with the potential for a patent application. With a large network in the painting industry, we - 6 Process & Innovation students at DTU - set out to place the industry on the path to sustainability. We, however, believe that a product needs to be more than just sustainable to gain real traction in the industry. We strive to solve some of the many problems we have met, lowering numbers of back injuries and being more sustainable, with a great product. We are so close to a final win-win-win product, being cheaper for the manufactures, more sustainable, as well as faster and safer to use for the painters.
