Attero, on Monday, said that it has completed an independently verified Life Cycle Assessment of the metals it pulls out of e-waste and old lithium-ion batteries. The assessment follows ISO 14040:2021 and ISO 14044:2021 standards. India's largest critical minerals firm now has scientific backing for something it's claimed for years — that its recycled metals are genuinely better for the planet than freshly mined ones.

Here's why that matters. Companies buying metal today aren't just asking "is it recycled?" anymore. They want numbers. Real ones. With ESG reporting getting stricter and Scope 3 emissions under the microscope, a vague sustainability claim doesn't cut it in a boardroom or an audit.

The assessment covers aluminium, copper, iron, zinc, tin, silver and gold — pretty much everything Attero pulls from waste streams. It looks at carbon footprint, sure, but also resource depletion, acidification, ecotoxicity, human toxicity, and fossil fuel use. All of it measured against virgin mining, metal for metal.

"The circular economy requires more than recycling; it requires measurable proof of environmental impact. This independently verified Life Cycle Assessment allows us to provide customers with scientifically validated environmental data for the metals we recover, enabling informed sourcing decisions and stronger sustainability reporting. As industries worldwide seek to reduce their environmental footprint and secure responsible sources of critical materials, verified environmental performance will become increasingly important alongside quality, purity and traceability. This milestone reinforces the role of urban mining as a scalable and sustainable source of critical minerals for the global economy," said Nitin Gupta, Co-Founder and CEO, Attero. 

What changes on the ground: buyers no longer have to take Attero's word for it, or rely on some industry-wide average that may or may not apply to them. They get numbers specific to the metal they're actually buying. That feeds straight into ESG disclosures, Scope 3 accounting, green procurement checklists — the stuff that used to be a headache to document.

None of this is new territory for Attero. The company holds over 50 global patents for extracting metals from complicated waste streams, and its process recovers 98% of usable material at purity above 99.9%. It's also become a real domestic source for lithium, cobalt, nickel, graphite, copper, gold and silver — metals India would otherwise be importing or mining conventionally.

The company said that this certification puts Attero a step ahead in an industry where everyone claims to be sustainable, but few can prove it. For companies trying to clean up their supply chains, that proof is starting to matter more than the pitch.
