West Marin Compost is more than just a great compost yard
West Marin Compost Project (WMC) started in 2013 driven by the desire of local community to create local solutions to organic materials management. Since then WMC has been producing compost and mulches that meet the needs of the agricultural and landscape industry as well as the homeowner. They have also played a supportive role in providing compost to the Marin Carbon Project, now the California Carbon Project.
WMC is also a research site where Sintana Vergara of Whendee Silver's lab at UC Berkeley is studying emissions from the composting process.
Biochar is a new innovative product now carried by WMC. It improves soils in a sustainable, lasting way. Carbon is taken from the atmosphere, locking it into the earth for hundreds of years, thereby reducing greenhouse gases.
