COMPOST: a natural choice

handsWe turn your food scraps, yard trimmings and other organic material into compost – right here at our Napa facility! We are upgrading our composting technology to divert more material from the landfill and create renewable fuel for our trucks – check it out in this video! Here’s more info on our Napa Renewable Resources Project.

Enrich your soil naturally, prevent erosion, conserve water, close the loop, save money, and fight global warming with Napa’s local compost – the benefits go on and on!  It’s perfect for farms, vineyards, gardens, yards, and landscaping projects.

We now accept food scraps and soiled paper for composting from all customers – here’s info on both our new commercial food composting program and residential food composting program.

You can also check out guidelines for successful compost usage in building projects and landscape architecture.

Do you have yard trimmings, food scraps, grape pomace, manure or other compostable material? 
We take it all for composting!  As a NRWS/NCRWS customer, you can use your brown compost cart.  Place it curbside on your regular service day.  For larger loads, contact us and order a yard trimmings or food compost debris box. To drop off yard trimmings or compostable food material, go to 820 Levitin Way, off Hwy. 29 & Tower Road in south Napa (click here for current rates).  Call 255-5200 for additional service information.
