This article investigates the potential environmental impacts of four-layer printed circuit board (PCB) production from cradle to grave. The study starts with a lifecycle assessment conventional PCB production. Then, alternative materials polyethylene terephthalate (PET), polylactic acid (PLA)/glass fiber composite and paper are investigated for substrate. A adopts copper as conductive material requires an etching process. changing deposition method additive by printing silver nanoparticles...
Abstract The demand for printed electronics (PE) is expected to increase improved functionality and autonomy of products in the context Internet Things, especially sensing communication. With this trend, environmental performance novel technologies growing importance, researchers are exploring ways make them more environmentally friendly using bio-based substrates additive printing methods. Conductive inks have highest impact life cycle PE, there two options decrease impact: recycling rates...
There is an increasing call for products following circular economy principles. Despite growing pressure, understanding of the current situation and development vectors largely missing. In this study, workshops were arranged six industrial companies manufacturing electronics operating in Finland to obtain empirical state implementation. During workshops, each company assessed a chosen product using set 51 strategies, i.e., circularity deck. The results indicated that principles implemented...
Printed electronics are expected to meet the increasing demand for improved functionality and autonomy of products in context Internet-of-Things especially sensing communication. With this trend, environmental performance novel technologies is growing importance. Several researchers had worked on concept develop more environmentally friendly electronic by introducing thin film fabricated bio-based substrates. The other path change printing method from subtractive additive methods such as...
There is a significant global rise in the amount of waste generated by electrical and electronic equipment (WEEE). This typically contains more than 20% plastic, which can have environmental benefits if it properly treated recycled. However, recycling plastics from WEEE challenging task due to complexity composition, consists several polymers, many contain heavy metals, additives, brominated flame retardants. study presents both technical concerns resource recovery plastics. By case (WEEP)...
