Back to Battery is a Dutch startup founded in 2024 by three experienced co-founders with complementary expertise in metallurgy, business development, and finance. Our company has developed a revolutionary hydrometallurgical process that recovers critical raw materials from lithium-ion battery black mass, exceeding mandatory recovery rates defined in the EU Battery Regulation. Through urban mining we recover materials with zero waste generation and a minimum of chemicals consumption and energy use, making us unique. As a result, we also achieve the lowest cost of the market. Our breakthrough technology makes us a truly disruptive player in circular battery technology for a sustainable energy transition.
