Attero is a deep-technology company dedicated to sustainable recycling and the recovery of green metals from electronic waste and lithium-ion batteries. The company is focused on building a circular economy through its proprietary technologies and infrastructure. Attero positions itself as both a technological innovator and an environmental partner working towards waste reduction and resource reuse on a global scale.
The company utilizes advanced processes to extract valuable metals with high efficiency and purity. With a strong emphasis on research and development, Attero continually develops and enhances its recycling capabilities. Headquartered in India, Attero serves a diverse range of partners across various industries, supporting them in managing their e-waste and battery recycling needs while promoting environmental responsibility.
Battery Technology
Attero specializes in sophisticated recycling processes for lithium-ion batteries, which represent a growing segment of their business. Since 2019, the company has focused on this area, with commercial operations starting in 2021. Attero states it is capable of processing all types of end-of-life lithium-ion batteries using a proprietary closed-loop recycling technology. This technology is designed to be agnostic to battery chemistry, handling types such as NMC, LCO, LMO, LTO, and importantly, LFP, which other recyclers sometimes avoid.
The process employed by Attero achieves high extraction efficiencies, reportedly over 98%, recovering battery-grade materials with purity levels up to 99.9%. Recovered materials include cobalt, lithium carbonate, nickel, copper, aluminum, and graphite. For specialized batteries like LTO, Attero also recovers titanium. The closed-loop system is described as zero-emission, water-free, and energy-efficient. The flexibility of the technology allows for the output to be customized, producing materials like cobalt metal or cobalt sulfate, and lithium carbonate or lithium hydroxide depending on market needs. This technology is supported by a portfolio of patents worldwide.
Recent projects
In April 2025, Attero signed a Memorandum of Understanding (MoU) with India’s National Institute of Solar Energy (NISE) to work on developing technologies for recycling solar photovoltaic panels. This collaboration aims to address the increasing volume of solar panel waste expected in the coming years.
Under the ‘Green Games’ initiative for the 38th National Games held in Uttarakhand, Attero supplied recycled metals with high purity. This partnership supported the event’s goal of promoting plastic-free and low-carbon sports events in India, which was the first of its kind for the National Games.
Investors
Attero has received funding from investors including Kalaari Capital, New Enterprise Associates (NEA), Forum Synergies, Draper Fisher Jurveston (DFJ), and Granite Hill Capital. These investments have supported the company’s growth and technological development.
In 2023, Ardian Infrastructure acquired the entirely of Attero’s operations in the Netherlands, which focused on waste management. This divestment allows the Indian parent company, Attero Recycling Private Limited, to concentrate its resources on its core e-waste and lithium-ion battery recycling business. Attero has also articulated plans for investing significantly over the next five years to expand its recycling capacity.
