Q3 2020: Circular manufacturing

The next quarterly theme is focusing on circular manufacturing. We are investigating if adopting circular approaches can create competitive edges and reap financial and reputational rewards. We’ll also look at what is already being done in the solar industry, and examine how such principles could be effectively integrated into business strategies.

We will need a solution’: Circusol’s five demonstration projects are providing insights into how circular-economy principles can be applied to PV.

Inverted sustainability: In the EU, a range of new projects and legislative acts determine the direction, with some suppliers of solar products already undergoing the process of identifying the sustainability hotspots.

Making solar sizzle: What is circular manufacturing, why is it important, and how is it being applied in the solar and storage industries? pv magazine’s UP initiative investigates.

Older modules for reuse, not refuse: Faulty modules and failures can destroy a PV project’s economics. But the modules themselves should not be destroyed, argues Eszter Voroshazi, the R&D manager of photovoltaics and energy systems at imec. She believes that modules can find a useful second life in price-sensitive solar markets.

Coming around: Given the number of batteries are required to decarbonize the power and mobility sectors, the industry is now preparing for a mountain of battery waste. Recycling is technically feasible, but is also subject to sensitive economics.

Materials in the circular economy: A number of companies are now racing to find new materials to replace toxic or otherwise unsafe elements in PV modules, in pursuit of circular economic ideals. In a similar vein, many researchers are also looking for ways to recycle and reuse some of these materials at the end of solar panel lifetimes. In line with these efforts, artificial intelligence and machine learning now play a critical role in identifying new chemical footprints for PV modules and cells.

Beyond carbon blinders, deployment fever: He wrote the first book on sustainability in solar and has a second on the way. Dustin Mulvaney, a professor at San José State University, has been investigating sustainability in the solar sector and the wider energy transition for well over a decade. And by applying a broad definition of sustainability – beyond the environment to include social justice goals – he believes that the solar industry can avoid reputational risks.

New inverter design coming around: Circular economy approaches in the solar industry have hitherto largely pertained to modules and batteries. Inverters, meanwhile, haven’t been in focus as much. Although these devices stand for less than 20% of the overall footprint of PV, they also contain significant volumes of valuable or toxic raw materials. Designing such products with their lifespans in mind has therefore become a critical step for the solar industry.

Designing circular solar modules: Amid a growing appetite for sustainability from customers, Lithuanian solar panel maker Solitek is applying circular principles to its production operations. Measures include embracing digitalization and new approaches to design. Project manager Tadas Radavičius has spoken to pv magazine about the company’s work and how Solitek is supporting European projects which are considering circular solar.

How a German startup aims to alleviate energy poverty with circular solar solutions: SunCrafter is a small German startup with a global ambition: to alleviate energy poverty by upcycling used solar PV modules. Having established an innovative business model, which sees it subsidizing its goals by meeting the infrastructure needs of big events and festivals, it has now partnered with EU-funded project Circusol to demonstrate the viability of circular renewables. pv magazine interviewed SunCrafter CEO and co-founder Lisa Wendzich as part of the UP initiative’s circular manufacturing quarterly theme.
