The development of Printed Circuit boards (PCBs) has so far followed a traditional linear economy value chain, leading to high volumes of waste production and loss of value at the end-of-life. Consequentially, the electronics industry requires a transition to more sustainable practices. This review article presents an overview of the potential solutions and new opportunities that may arise from the greater use of emerging sustainable materials and resource-efficient manufacturing. A brief contextual summary about how the international management of Waste PCBs (WPCBs) and legalization have evolved over the past 20 years is presented along with a review of the existing materials used in PCBs. The environmental and human health assessment of these materials relative to their usage with PCBs is also explained. This enables the identification of which eco-friendly materials and new technologies will be needed to improve the sustainability of the industry. Following this, a comprehensive analysis of existing WPCB processing is presented. Finally, a detailed review of potential solutions is provided, which has been partitioned by the use of emerging sustainable materials and resource-efficient manufacturing. It is hoped that this discussion will transform existing manufacturing facilities and inform policies, which currently focus on waste management towards waste reduction and zero waste.

“…For example, ferroelectric materials such as P(VDF–TrFE) can be used to boost TENG output when permanently polarized. 19 Apart from the inherent material properties, it is also important to achieve a high degree of contact area at the contact interface. This can be achieved in various ways: through ultra-smooth surfaces, via conforming surfaces having particular patterns ( e.g.…”

“…Barium titanate, as a typical piezoelectric material, has attracted extensive attention due to its excellent piezoelectric, dielectric, and ferroelectric properties and wonderful biocompatibility since its appearance. 26,27 Herein, piezoelectric barium titanate nanoparticles (BTNPs) were selected as research objects to investigate the effects of BTNPs with different crystal phases and piezoelectric properties (i.e., BTO, U-BTO, P-BTO) on the activity of BC cells with or without external ultrasound stimulation (US). In this study, cubic barium titanate (BTO), tetragonal unpolarized barium titanate (U-BTO), and tetragonal polarized barium titanate (P-BTO) shared the same morphology and particle size but were different in the intensities of internal ES generated under exogenous mechanical stimulation, with the ES intensities of BTO, U-BTO, and P-BTO being 0 mV, 425 mV, and 886 mV, respectively.…”

Triple-negative breast cancer (TNBC) is an aggressive BC subtype with a higher metastatic rate and a worse 5-year survival ratio than the other BC. It is an urgent need to develop a noninvasive treatment with high efficiency to resist TNBC cell proliferation and invasion. Internal wireless electric stimulation (ES) based on piezoelectric materials is an emerging noninvasive strategy, with adjustable ES intensity and excellent biosafety. In this study, three different barium titanate nanoparticles (BTNPs) with different crystal phases and piezoelectric properties were studied. Varying intensities of internal ES were generated from the three BTNPs (i.e., BTO, U-BTO, P-BTO). In vitro tests revealed that the internal ES from BTNPs was efficient at reducing the proliferative potential of cancer cells, particularly BC cells. In vitro experiments on MDA-MB-231, a typical TNBC cell line, further revealed that the internal wireless ES from BTNPs significantly inhibited cell growth and migration up to about 82% and 60%, respectively. In vivo evaluation of MDA-MB-231 tumor-bearing mice indicated that internal ES not only resisted almost 70% tumor growth but also significantly inhibited lung metastasis. More importantly, in vitro and in vivo studies demonstrated a favorable correlation between the anticancer impact and the intensities of ES. The underlying mechanism of MDA-MB-231 cell proliferation and metastasis inhibition caused by internal ES was also investigated. In summary, our results revealed the effect and mechanism of internal ES from piezoelectric nanoparticles on TNBC cell proliferation and migration regulation and proposed a promising noninvasive therapeutic strategy for TNBC with minimal side effects while exhibiting good therapeutic efficiency.
