Biodegradable plastics, whose basic suitability for the production of PCBs at laboratory and demonstration scale (TRL2-3) we have already demonstrated, can be a key to solving the recycling problem mentioned above by enabling a recycling-friendly PCB design. The goal of the project is to develop demonstrators of electronic assemblies to be manufactured from sustainable and environmentally friendly raw materials as carrier substrates at technical scale using industry-standard machinery. Also to enable recycling through a biodegradation process of the composite material as a potential key to cost-efficient and environmentally friendly strategic technology metal recycling. || Rapidly increasing volumes of short-lived commercial electronic products are generating ever-increasing amounts of electronic waste. One of the main problems is the decomposition of electronic circuit boards after the use phase. The substrate materials are mostly made of petroleum-based thermosets, some of which contain ecologically harmful brominated flame-retardants. Since a large part of PCB (printed circuit boards) production takes place in Asia, the EU has no influence on the composition and environmental compatibility of this base material for electrical engineering and electronic components. Due to the non-recyclable thermoset material used to date, the separation of metals and organic components is still a challenge to solve in terms of carbon footprint and cost. Global sustainability requires a comprehensive approach that includes innovative manufacturing processes for composites and electronics as well as environmentally friendly disposal and recycling strategies such as design for recycling. Strategic technology metal (such as copper, silver and gold), as well as key raw material recycling is also an important issue. || flexible materials and devices from high-performance composites with tailored thermal, electrical and mechanical properties for use in electronics, which is part of the global trend towards heterogeneous integration. The overall goal of BEATRICE is to initiate the production of sustainable printed circuit boards for electronic components to replace the usual standard material (such as FR4), enable a new design for recycling and producible in Europe. This includes the successful testing and dissemination of production technology for clean and sustainable recyclable PCBs, the successful implementation of PCB substrates in traditional subtractive (and alternative additive) technologies that enable requirement-free introduction with readiness and compatibility of traditional FR4 manufacturing equipment, and the successful TRL 4 validation of an electronic assembly (module circuit) as an example project (electronics development kit with Industry 4.0 mindset). Based on the successful electronic testing at the end of the proposed project, improved recyclability to be initiated after successful testing and dissemination of this novel production technology for clean and sustainably recyclable PCBs. Thus, BEATRICE supports the circular economy and reduces the consumption of fossil raw materials a
