Colum Riley got into compost early in life, literally, growing up on on the biodynamic farm in Camphill Village Kimberton Hills in Kimberton, Pennsylvania. He received his BA in marketing communications from Berea College. After a brief career in sales and marketing, he moved to Hudson, New York and in 2003 was elected to the City Council. In 2008 he received his MBA from Loyola Marymount University and in 2009 founded Malibu Compost, the first Demeter Certified Biodynamic® Compost in the country.

Since its inception, Malibu Compost has spread Biodynamic compost and compost teas across the U.S., with soil retailers in 23 states and counting and online retailers nationwide. Malibu employs Rudolf Steiner’s associative economics principles in business, partnering with organic dairy families to ensure GMO-free, organic cow manure supplies. Recently Malibu Compost received a loan from RSF Social Finance to assist with national expansion.

Colum oversees all aspects of Biodynamic compost production on multiple farms, from sourcing inputs and biodynamic preparations to the most stringent testing of any soil company in the nation. Colum speaks to thousands of avid gardeners and farmers every year, introducing and advancing the principles of biodynamic agriculture across the United States. He is also a member of the US Composting Council, the Association of Compost Producers, and, of course, the Biodynamic Association.
