Reuse of Wind Blade:

We're facing a big problem when it comes to the recycling of wind turbines.

They generally have a service life of around 20 years, and they're unfortunately made of materials that aren't easy to recycle.


85% of the components in a wind turbine, such as the steel mast and electrical parts composed of metals like copper, can be recycled.





The problem however is that the turbine blades cannot be recycled, and they make up 10% of Europe's waste stream of fibre-reinforced composite materials.


By 2050, The University of Strathclyde estimates that globally there will be 2 million tonnes of wind turbine waste needing safe disposal.


Now for the good news!

Several innovative solutions have emerged, from using them as a bike shelter (pictured below), to using them to build bridges. The materials that make them hard to recycle also make them durable and strong, allowing them to be reused in a number of ways.


In 2021, Siemens Gamesa launched the world’s first recyclable wind turbine blade for commercial use, meaning that at the end of its lifespan the blade can be disassembled and recycled into new applications.


There are some progress taking place in the recycling of thermoset plastics in research projects in recent years.Advanced Pyrolysis recycling process will emerge as a solution to this problem in the coming years.

Today's KNOWLEDGE Share:PLA BOTTLE

Today's KNOWLEDGE Share Ever wondered how we can reduce plastic pollution in India? The Mysuru-based Defence Food Research Laboratory (DFRL), affiliated with the DRDO, has launched an eco-friendly remedy with the introduction of biodegradable water bottles. Crafted from sustainable Polylactic acid (PLA) material, these bottles not only combat plastic waste but also contribute to reducing the overall carbon footprint. The best thing about this bottle is its all-encompassing sustainability approach – the bottle, cap, and label are all compostable. This innovation, derived from 100% bio-based and renewable sources, sets us on a path towards environmental conservation and fosters a greener and more sustainable future.

Today's KNOWLEDGE Share:High and low shear rate changes in Rheology

-

Today's KNOWLEDGE Share If a relatively high Mw grade flows from thin to thick, as shown in the picture, and if the time needed to fill the thick section is way shorter than the average polymer relaxation time, the polymer will not be able to reach its higher viscosity (corresponding to higher thickness/lower shear-rate). I am assuming here the polymer reached equilibrium low viscosity in the thin section, say for instance because it is much longer. Any pressure prediction not accounting for transient rheology would then overpredict the pressure to fill.Of course the diverging flow will further complicate the situation and mess with the molecular orientation created in the thin section, but to what extent ? Since this is more of a reasonable "conjecture", don't take this for granted, and discuss or share your opinion in the comments. There are hundreds of Rheology papers on the "4:1 contraction flow". Not sure I have ever seen any on the..."1:4 expansio
