The document discusses a project to redesign bathroom toilets to reduce their environmental impact and water usage over their lifespan. It analyzes the life cycle of existing toilets and identifies opportunities to decrease water consumption and use more sustainable materials. A proposed new toilet design called the Karner Blue is presented, which uses vacuum suction instead of water for solid waste and a waterless cartridge for liquids. This design is estimated to save over 1.5 million gallons of water usage per year and $60-75 per household annually while promoting more sustainable production and end-of-life recycling.
