The Role of Secondary Resources in the Austrian Energy Transition

A concerted worldwide effort to reach the goals of the Paris Agreement brings about a substantial increase in raw material
demand for the production and deployment of clean energy technologies. Yet, raw materials required for the energy transition
show high emissions intensities in mining and production. Producing secondary resources, in particular metals and critical
raw materials (CRMs) like rare earth metals, from recycling End-of-Life (EoL) waste streams of PV panels, e-vehicles, and
wind turbines (PEW) involves substantially less energy input than converting it from ore. With this background the aim of
our project was 1) to quantify the potential of EoL waste streams of PEW, including the CRMs for recycling, 2) to project
the future secondary resource potential assuming a decarbonising scenario of the Austrian economy, and 3) to assess the economic
impacts from potential recycling loops using the macroeconomic model WIFO.DYNK. Results show that from an investor's point
of view, recycling plants appear not profitable under the selected price assumptions. Introducing a minimum "gate-fee" for
EoL waste streams can yet ensure the profitability and investments for recycling plants. From a macroeconomic perspective,
recycling of EoL PEW devices generates value-added, employment as well as dividends in climate mitigation and resource or
energy security.
