Study Warns of Microwaves' Growing Environmental Impact in EU
A recent study by the Fraunhofer Institute for Reliability and Microintegration (Fraunhofer IZM) has shed light on the environmental impact of microwaves in the EU. Titled 'Environmental assessment of microwaves and the effect of European energy efficiency and waste management legislation', the study reveals concerning trends and highlights the need for targeted regulations.
Microwaves, currently the most popular type of oven in the EU, are set to reach nearly 135 million units by 2020. However, their lifespan has significantly decreased, from around 10 to 15 years in the late 90s to between six to eight years today. This shortening lifespan, coupled with consumers replacing appliances before they reach the end of their useful life, contributes to a fast-growing waste stream of discarded electrical equipment.
The study found that microwaves' environmental 'hotspots' are the materials used in manufacturing, the manufacturing process itself, and end-of-life waste management. Existing regulations are not adequate to reduce these impacts, and specific design regulations are needed. Microwaves emit 7.7 million tonnes of carbon dioxide equivalent per year in the EU, equivalent to the annual emissions of 6.8 million cars. Electricity consumption, with an average microwave using 573 kWh over its lifetime, has the biggest impact on the environment. In total, microwaves across the EU consume an estimated 9.4 terawatt-hours (TWh) of electricity every year, equivalent to the annual output of three large gas power plants.
The study underscores the urgent need for targeted regulations to address the environmental impacts of microwaves. With their lifespan decreasing and consumption of resources increasing, action is needed to ensure sustainable production, use, and disposal of these appliances.
