Waste Metals

Half of all the metals used today have a lifespan of fewer than 10 years.


As a society, we use around 61 different metals.However, more than half of them will end in a landfill or in a recycling yard within ten years.This speaks to the enormous amount of wastage that we accrue as a civilization.




Billions of tonnes of metals are mined each year, which accounts for 8 % of all greenhouse gas emissions. Now, if we could save the metals that we discard, it could bring down both mining and greenhouse gas emissions.


The results are from an industrial ecology group at Yale University.

The only notable exception to this list is gold, which continues to be maintained and reused for centuries.Perhaps we should start mandating metal recycling and make it profitable to extract waste metals from landfills.

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
