A focused mandate.

Earthworks was structured to deploy capital into a single, high-conviction opportunity: the under-served California integrated waste market. As overseas processing markets contracted, valuable materials began returning to domestic landfills — an inefficiency that creates room for a disciplined operator.

The company complements its handling and processing footprint with acquired intellectual property and technology for critical minerals recovery, expanding the value extracted from each ton processed.
