Product Stewardship For ASSA, sustainability is an integral part of product innovation. Every attempt is made to ensure that newly designed products are as energy efficient as possible. The intention is to develop new product concepts that solve customer problems and create customer value, based on sustainable solutions and processes. When developing new products, ASSA uses a Sustainability compass to outline the sustainability vision for individual products and includes eight focus areas: raw materials, water, virgin material, end-of-life reusability, recyclability, in-life energy consumption, carbon footprint and financial cost. The compass is used to track performance and communicate the importance of sustainability-related design criteria among all stakeholders involved in the development process.
