SuStainability “the semiconductor industry is very skeptical about recycling of semis” an interview with Ole Gerkensmeyer Vice President EMEa Sales at nexperia by Engelbert Hopf senior editor at WEKa Fachmedien the amount of electronic waste is increasing worldwide year on year With the imminent transition to an allelectric society the amount is likely to increase even further We spoke to Ole Gerkensmeyer nexperia about the opportunities for the semiconductor industry to move towards a circular economy Without comprehensive electrification and digitalisation it will hardly be possible to achieve the goal of an allelectric society Conversely what does this mean for electronic waste? the untaR “ewaste monitor 2024” records ewaste as the fasted waste stream globally with a growing trend and so does the Eu by the way based on data for the year 2022 besides the un we have consensus across larger economic expert groups like McKinsey and others that cloud computing and ai transportation in all forms the electrification of many industries like steel and construction as well as the need to respond to the consequences of global warming desalination and more air conditioning will require an even faster growth of electronic demand – and unfortunately ewaste Can you give us an idea of the current dimension of electronic waste? to what extent has it increased in recent years? the unitaR report lists 62 m tons of ewaste for 2022 Growth is here are there any estimates as to how big the problem could become in the future if things continue as they are? are there also committed scenarios for the future? Short answer unitaR see 4 scenarios normal progressive ambitious and aspirational with growing amount of waste but also growing amount of biz potential but the graphic suggests that the higher the purchasing power of a country the higher contribution to ewaste as a scenario moving forward as we aim to reduce world hunger and poverty one of the consequences likely is an exponential increase in ewaste Committed scenarios well in the Eu we have now the right to repair since 2024 which is a start but nowhere close to the necessities for reducing ewaste beyond recycling the Eu recommends circular economy and “highest possible reuse“ but so far i have not yet met a single electronic company who does that Electronic waste ranges from large appliances such as those used in medical technology to electronic toys Which of these categories contributes most to the growth of electronic waste? Please note that transportation with electric cars is nOt yEt a category the buzzwords that are repeatedly mentioned in this context include recycling and urban mining What significance do recycling and urban mining have for the supply of raw materials in the electronics industry today? they could supply a growing percentage of raw material needs However with reuse beyond recycling that need would be more meaningful • We have unnecessary global ewaste movements to other countries • urban mining as recovery of metals from ewaste is at low percentages • urban mining does represent a massive revenue potential currently not considered which is exceeding 30 – 50 b uSD depend ing on the scenario if we break the whole thing down to power semiconductors what significance has recycling had for this sector so far and what significance could it take on in the future? the semiconductor industry is very skeptical about recycling of semis given that any known processes are rather destructive to the im age bluedesign stock adobe com 8 PCiM Magazine 02 2024
