circular economy

Europe’s solar boom is hiding its waste through exports, according to a new study. Instead of recycling, as expected under European regulations, vast amounts of solar panel waste are exported, undermining sustainability goals. The researchers suggest a digitized value chain as a potential fix to work toward a circular economy.

A European consortium of 11 commercial and non-profit organizations is developing several technologies to make use of end-of-life PV panels by either re-deploying them or by recovering and reprocessing the silicon.

Europe’s leading battery maker, Northvolt, has signed a $5 billion non-recourse project financing arrangement to enable the expansion of Northvolt Ett in northern Sweden. The deal represents the largest green loan raised in Europe to date.

Recycling is of significant importance in a circular economy, yet some challenges have to be faced when recycling PV modules. The novel Hot Knife method to separate the crystalline silicon photovoltaic module front glass from the backsheet contributes only a few permill to the life cycle related potential environmental impacts of PV electricity.

Dutch importers that sell solar panels to clients in the Netherlands will have to pay a recycling charge of €40 ($42.50) per ton from July 1. They currently pay just €6.50 per ton.

Starting this year, ground-mounted solar modules in Germany can be replaced before the end of their service life, unlocking gigawatt-scale potential for new generation capacity without lengthy permitting processes or the need for new sites. Opinions differ as to what should happen with the decommissioned but still functioning modules, as pv magazine Deutschland’s Sandra Enkhardt reports.

Italian startup Tialpi is developing a process to recycle end-of-life solar panels that promises to recover 100% of a PV module’s weight. The new plant design is currently being tested at the company’s facility in the Italian northern province of Biella.

The 22 nations which have had their “recovery and resilience” spending plans approved by the European Commission are set to devote billions to clean energy facilities, with the cash set to be disbursed in three payments to the end of next year.

A European consortium consisting of Italian energy agency Enea and the French Alternative Energies and Atomic Energy Commission, among other entities, has developed a plan to build a low-emissions pilot line to recover critical and precious metals such as silicon, indium, gallium and silver. The line will be designed to reintroduce new materials and new products into the production cycle.

Production waste puts a dent in the perception of sustainability of batteries. Northvolt, however, has partnered with a young Swedish company to make the best use of the battery production waste, and also help to decarbonize the fertilizer industry while they are at it.
