“…Despite the promising results, the fundamental disadvantage of recycling in Soxhlet extraction is its duration and energy consumption. In contrast, PLA-PCB recycling with ultrasonic sanitation is twice as fast as in the Soxhlet apparatus 19 and energy-efficient. It should also be noted that, unlike Soxhlet extraction, ultrasonic sanitation does not require running water for cooling.…”

“…Previously, an article 19 showed the possibility of PLA-PCB recycling under extraction conditions in a Soxhlet apparatus, in which ethyl acetate dissolved PLA and separated it from the filler and the copper tracks. Despite the promising results, the fundamental disadvantage of recycling in Soxhlet extraction is its duration and energy consumption.…”

Due to the ever-increasing amount of electronic waste (e-waste) worldwide, the problem of the effective disposal of printed circuit board waste (WPCB), which are environmentally hazardous, difficult to recycle and economically valuable products, has become a major environmental challenge. Conventional WPCB recycling techniques have low efficiency and require tough processing, such as heat treatment and high pressure. This paper presents a new composite material for the manufacture of printed circuit boards (PCB) that can be easily recycled into their original components and reused. In addition, the most valuable PCB components (electronic components containing precious metals) can be easily separated from the printed circuit board and reused. This study demonstrates the benefit of using biodegradable polymers as binders for PCBs in terms of environmentally friendly and efficient recycling.

“…Abdulrhman et al showed that polycaprolactone (PCL) could be used for circuitry integration, staying in the regime of flexible substrates [17]. Yedrissov et al [18] very recently proposed a new method for producing polylactic acid (PLA)based PCBs to replace environmentally hazardous polymer binders with a biodegradable solution. The production and the recycling process were presented, the proposed material with the recycling method aims to save and reuse the most valuable components of the PCB.…”

“…Regarding the assembly of components to biodegradable substrates, soldering is often applied. A low-temperature solder alloy based on bismuth usually is necessary because of the biopolymer low thermal resistance [18,19,29,45]. As the study by Henning et al, 2019 [29] states, the solder joints exhibit a higher shear strength than those made by conductive epoxy-based adhesive.…”

Biodegradables are a promising path for the future of electronics in a greener mindset. The review study focuses on their applications and past and current research results. The paper also investigates the application of nanomaterials as fillers to control or increase the physical (electrical, mechanical, thermal) properties of biodegradable biopolymers. These biodegradables and nanocomposites are already effectively used in prototypes and advanced application areas with demanding requirements, such as flexible and wearable electronics, implantable or biomedical applications, and traditional commercial electronics. The nanoenhanced biopolymer substrates (e.g., with improved gas and water barrier functionalities) sometimes also with integrated, nanoenabled functionalities (such as electromagnetic shielding or plasmonic activity) can be beneficial in many electronics packaging and nanopackaging applications as well.

“…Such materials were investigated from many different aspects recently, based on different substitutes of traditional glassfiber reinforced epoxies. Banana stems [1], rice husk [2], flax-fibres with linseed oil [3,4], other times polylactic-acid (PLA) [5] or Cellulose-Acetate (CA) [6] was used for experiments.…”
