Prompted by the dire forecasts for increased resource extraction and waste generation, and their detrimental effects on climate and biodiversity, a Circular Economy Action Plan has been put forth where electronics and electronic equipment have been identified as a priority product group with circularity potential. With an annual growth in waste of 2%, this group is one of the fastest growing waste streams in the EU, while less than 40% of electronic waste is recycled within the EU. There is a need to explore new options for electronics that are designed for reuse, repair, and high-quality recycling. To address this challenge, several factors must be considered such as the Industrial End User’s (IEU) specifications, Life Cycle Analysis (LCA) and the products end-of-life (EoL). Printed electronics (PE) is an additive manufacturing method that can address these challenges and is characterized by its versatility, scalability, and low material usage, thus making it an ideal candidate for a circular production of electronics in general. Flexible and even stretchable electronics can be obtained with this method by printing conductive and dielectric inks on flexible/stretchable substrates opening new applications in the market. However, like traditional electronic production methods, current life cycle for a PE product starts with materials (substrate, conductive and dielectric materials) obtained through mining of raw materials. These materials are put into production lines, consisting of large volume analogue printing, gluing on discrete components and lamination processes. The EoL are either landfills or incineration, which in both cases, destroys precious materials, thus forcing the use of mined raw materials. The main goal of Sustain-a-Print (SaP) is to open new life-cycle routes and to design and implement sustainability into each step of the life cycle. This includes choice of materials, their usage, their origin, their processing, assembly, and EoL.

由于资源开采和废物产生的增加及其对气候和生物多样性的不良影响的可怕预测，提出了循环经济行动计划，其中电子和电子设备被确定为具有循环潜力的优先产品组。废物每年增长 2%，该类别是欧盟增长最快的废物流之一，而欧盟境内回收的电子废物不到 40%，因此需要探索专门设计的电子产品的新选择。再利用、修理和为了应对这一挑战，必须考虑几个因素，例如工业最终用户 (IEU) 规范、生命周期分析 (LCA) 和产品寿命终止 (EoL)。一种可以解决这些挑战的增材制造方法，其特点是多功能性、可扩展性和低材料使用量，从而使其成为一般电子产品循环生产的理想选择，通过这种方法可以获得柔性甚至可拉伸的电子产品。印刷柔性/可拉伸基材上的导电和介电油墨在市场上开辟了新的应用然而，与传统的电子生产方法一样，PE产品的当前生命周期始于通过原材料开采获得的材料（基材、导电和介电材料）。被投入生产线，包括大批量模拟印刷、分立元件粘合和层压工艺。最终产品要么被填埋，要么被焚烧，这两种情况都会破坏珍贵的材料，从而迫使使用开采的原材料。 Sustain-a-Print (SaP) 的主要目标是开辟新的生命周期路线，并在生命周期的每个步骤中设计和实施可持续性，其中包括材料的选择、用途、来源、加工和组装。和停产。
