Company Overview#
MK Solar is an eco-friendly energy and resource-circulation company whose core business is supplying renewable fuel. Its main operation is supplying wood pellet and biomass renewable fuel to domestic power plants, alongside a resource-circulation (ESG) business that recovers rare earth metals from end-of-life permanent magnets and industrial waste.
The company started by exporting solar materials such as polysilicon, then expanded into renewable power-plant fuel supply and international freight forwarding. More recently it has grown rare earth recycling as a new ESG growth area.
Technology & Product#
- Renewable fuel supply (core): Steady supply of wood pellet and biomass renewable fuel to domestic power plants.
- Rare earth and valuable-metal recovery (ESG): Extracts and regenerates rare earth components from waste magnets and electronic scrap using eco-friendly leaching and high-purity separation, restoring purity and performance close to new magnet material.
- Waste acid and solvent purification: Cleans waste phosphoric acid, processing oils, and used solvents so they can be reused, cutting both waste-treatment and raw-material costs.
Market & Use Cases#
Core customers are power generators and energy buyers that need renewable fuel, along with magnet, motor, electronics, and semiconductor manufacturers that generate rare earth scrap or chemical waste. These customers face both high prices for imported rare earth inputs and waste-disposal costs.
Useful pilot settings include factory waste streams where rare earth recovery can replace imported material, and chemical processes where waste acid or solvent recovery can cut disposal volume.

Collaboration Relevance#
MK Solar can work with power generators seeking renewable fuel, as well as magnet and motor manufacturers, electronics and semiconductor plants, and chemical processors that want to recover value from their waste streams. A practical pilot could start with a defined factory waste batch and test recovery purity and yield.
For Korea-Europe collaboration, the company is relevant to critical raw material security, magnet supply localization, and circular-economy programs that aim to reduce dependence on imported rare earth material.
