Certified Organic Compost  
Oliveira Enterprises, Inc. is a family owned and operated business since 1996. It is run by a father and son duo, Carlos and Brian Oliveira. Carlos immigrated to The United States in 1969 from the Azores, Portugal. Carlos brought his love for cows and farming from the islands and quickly began milking cows at a local dairy in Tracy, CA after his immigration to the US. After six years working on a dairy, he ventured out and started his own dairy business. After 13 years, the dairy came to an end. Carlos had another idea and thus started the merging of his previous dairy experience with the green waste recycling business we are in today.

Family owned and operated business
After a lot of hard work and determination, OEI began to grow. It evolved from a simple idea to merge green waste recycling with cattle feed into a multi-faceted business. We've expanded our expertise into organic compost, wood recycling, and various custom services while keeping our roots tied to farming and raising cattle.
