a growing headache when it comes to waste. turbines are built to withstand the forces of nature, they re flexible, light and superstring. flexible, light and super strong. but that s also where the problem lies. when they reach the end of life, they re really hard to recycle. while the steel in the towers can be reused, the massive blades are almost indestructible. and as older models are replaced, many get dumped in landfill. by 2050, there could be 43 million tonnes of redundant blades globally that need to be dealt with. it is problematic because we want the renewable energy to be truly sustainable, and if you have a waste material that goes to land filling, it s not truly sustainable. it s a problem players have been scrambling to figure out. and we might now have some answers.
by 2030, wind power could supply a fifth of the world s electricity. we need clean energy, but this green industry has a growing headache when it comes to waste. turbines are built to withstand the forces of nature, they re flexible, light and superstring. but that s also where the problem lies. when they reach the end of life, they re really hard to recycle. while the steel in the towers can be reused, the massive blades are almost indestructible. and as older models are replaced, many get dumped in landfill. by 2050, there could be 43 million tons of redundant blades globally that need to be dealt with. it is problematic because we want the renewable energy to be truly sustainable, and if you have a waste material
and if you have a waste material that goes to landfilling, it s not truly sustainable. it s a problem players have been scrambling to figure out. and we might now have some answers. there have been creative ways of reusing wind turbine blades, like this bike shed. they ve even been repurposed for playgrounds, bridges and building cladding. but this will not really tackle the growing volumes. but this won t really tackle the growing volumes. one immediate solution is to chop up and finely shred them. it s burned as fuel and used as an ingredient for cement production. this us plant has already handled more than 3,400 unwanted blades. now, turbine makers siemens gamesa have had a breakthrough of its own. it manufactures some of the world s biggest
During our journey through life, we are blessed when we encounter special kindness — those spirits that touch our hearts and bring something extra to the table. It saddened me
truly sustainable, and if you have a waste material that goes to land filling, it s not truly sustainable. it s a problem players have been scrambling to figure out. now turbine makers siemens gamesa has had a breakthrough. it manufactures some of the world s biggest blades at its site here. and while this one looks like any other, it can be recycled. it all comes down to a resin called epoxy, which acts like a really strong superglue, binding together the fibreglass, binding together the fibreglass. usually, this is incredibly tough to break down, but not here. we change something in the backbone of the chemistry, this has gone through our recycling process, we just turn it around. you can see all the different glass hairs placed through in
