Solution Overview

Problem

Current steelmaking technologies rely on fossil fuels, such as coal and natural gas, which are non-renewable and contribute to CO2 emissions, limiting the availability of sustainable and carbon-neutral methods for producing iron and ferro-alloys.

Innovation Solution

A process utilizing coffee as a bio-based carbon source to reduce iron oxide to metallic iron, where coffee grounds or beans are used as the carbon source, either in their raw form or after heat treatment, and heated in an inert atmosphere to convert iron oxide into iron, potentially replacing traditional fossil fuel-dependent methods.
