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 manfucaturing 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, similar to 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.

The SAFARI project aims to develop new 2D materials using sustainable and safe processes. The project focuses on creating hybrid formulations of MXenes and Graphene (Gr), which are known to possess unique and desirable properties such as thermal stability electrical conductivity. The goal of the project is to develop sustainable and safe materials that can be used in a wide range of applications such as biosensors, conductive ink, and EMI shielding. The SAFARI project begins with the preparation of precursor compounds known as MAX phases. These compounds are then used to produce two types of MXenes (Ti3C2 and Cr2C) which are further functionalized to enhance their properties and increase their affinity with Graphene. The resulting 2D hybrid materials are created using two different methods, and their structural, morphological, and functional properties are thoroughly examined. One of the main strengths of the SAFARI project is that is allinged with the SSbD principles. Thus assessment of the toxicological and eco-toxicological profiles of the new materials through a range of tests and assays will be conducted. In conclusion, the SAFARI project represents a significant step forward in the development of 2D hybrids with MXenes/Graphene for use in a wide range applications.

Combining robust sensor technologies with the inherent advantages of electrochemical strategies, nano-molecularly imprinted polymers, and multivariate and pattern data analysis, BorderSens will enable highly accurate selective detection of trace levels of illicit drugs and precursors. With borders being important gateways for the entrance of illicit drugs and their precursors, custom and border control authorities are facing pertaining challenges to detect such dangerous substances and safeguard the public. The main challenges posed by currently used on-site methods to detect illicit drugs and precursors are low accuracy, in the case of colour tests, and high cost and low portability, in the case of spectroscopic tests. In the light of a pressing need for better drug test systems at EU borders, the ultimate research aim of the BorderSens is to develop a portable, wireless single prototype device with the capability to quickly test for different types of drugs, precursors and adulterants/cutting agents, with outstanding accuracy and reduced false positives and false negatives. BorderSens will demonstrate the innovative technological solutions at seven demonstrations sites at EU borders with end-users and ensure exploitation plans guaranteeing strong impact. BorderSens brings together universities, a big manufacturer of electrochemical sensors, a specialised SME, ten end-users i.e. forensic institutes, police forces and border authorities, and a high quality external advisory board, to provide an excellent scientific-technical perspective and a straightforward exploitation route, with great impact on the safety of EU citizens.
