Electronics and lighting CLOSING MATERIAL LOOPS

Jessika Luth Richter, PhD researcher

1 September 2017 Mijödialog Research Project @ IIIEE

"Styrmedal och affärsmodeller för slutna materialkretlopp" "Policy instruments and business models for closed material loops" Aim to evaluate: 1. Existing policy instruments (EPR) for collection and of energy efficient lighting products in Northern Europe 2. Material loop closure in the case of lighting products with particular focus on critical materials

a) Mining & milling

Environmental impacts: • land use • leachate into groundwater (e.g. heavy metals, arsenic, fluorides, sulphides, thorium and uranium) b) Flotation • dusts emissions ( with contents of e.g. heavy metals, thorium, uranium) • Air emission of process chemicals (SO2, HCl) • waste water generation • GHG emissions due to energy use

c) Further Metallurgical

• Relatively high metal prices after global recession

• Growing concern, particularly for critical materials “Circular economy approaches ‘design out’ waste and typically involve innovation throughout the value chain, rather than relying solely on solutions at the end of life of a product.”

• Relatively high metal prices after global recession, particularly for critical materials • Some WEEE streams became profitable for recycling without regulation • Competition for some valuable WEEE = producer concerns in meeting EPR targets and proposing EPR 2.0 • Individual targets for some WEEE streams considered (Art 7 (6)), particularly temperature exchange equipment, photovoltaic panels, small equipment, small IT and telecommunications equipment and lamps containing mercury.

“For gas discharge lamps, with concerns over high mercury content, incentives should be focusing on collecting more discarded products, as well as achieving high mercury removal efficiency and also promoting at the same time.”
