Day 167 – When we think of renewable energy sources, we usually think of clean, waste free options. Sadly, even sustainable energy sources can create waste. According to a study by University of Cambridge (2017), turbine blades are set to account for 43 million tons of waste by 2050. Most blades end up in landfills, because they are hard to recycle.
Thankfully, wind turbine maker Vestas, unveiled new technology which it says enables wind turbine blades to be fully recycled, avoiding the dumping of old blades. Using the new technology the glass or carbon fiber is separated from the resin and then chemicals further separate the resin into base materials, that are “similar to virgin materials” that can then be used for construction of new blades.
The project aims to develop the technology for industrial scale production within three years and also sees potential for the technology to be used for airplane and car components.
If we are to fully embrace a world where renewable energy sources are common place, we need to start finding ways to recycle all the materials involved in harnessing these sources of energy. Sending turbine blades and solar panels to the landfill will not help our situation.
