E-Waste/Printed Circuit Board Recycling

Electronic waste is the fastest-growing portion of the municipal waste stream expected to grow to 67.2 million tonnes by 2026. Scrap printed circuit boards from this e-waste can be processed to recover valuable metals and elements...



E-Waste is a global issue. It is the fastest growing waste stream in the world. The highest value components in Ewaste are printed circuit boards. Typically, these are processed by smelters outside North America. EnviroLeach offers a viable domestic alternate solution for the treatment of printed circuit boards. EnviroLeach is also developing hydrometallurgical recovery applications for tin and platinum group metals which present potential for increased operating margins.


EnviroLeach’s E-Waste pilot plant has a 4,800 tonne per year capacity. Commercial-scale testing was completed throughout the first half of 2020. The pilot plant includes state of the art grinding and separation circuits as well as a chemical leach circuit that uses our proprietary
recyclable formulation. The E-waste business model positions EnviroLeach as a competitive E-waste downstream processor.


Our business model is based on sourcing E-waste supply from three market segments. For each segment we offer unique advantages and pricing models. EnviroLeach is confident its price models are competitive with smelter payments. EnviroLeach has commenced building a
diversified supply chain across North America. Although the COVID pandemic has impacted E-waste availability across the market the Company is confident the supply chain will be established over the second half of 2020. International partnership opportunities will be pursued
according to a licensing and royalty model.

Electronic Waste is a highly complex and heterogeneous group of materials. We have the technology and expertise required to correctly separate and recover silver, gold, palladium, copper and other valuable metals. 

Recycled printed circuit boards contain the majority of the value in E-Waste. These boards typically contain over $3,500 USD worth of metals per tonne. This is significantly higher than the typical $100 - $500 USD per tonne of conventional mining ores.

261,000 tonnes of scrap printed circuit boards are generated every 30 days...
