Green Waste Composting

 

Green waste is any general yard waste, sticks, plants and flowers, branches, grass, or leaves. This material is diverted from the landfill and composted into a high quality compost product. Our composting operation takes green waste and mixes it with food waste and other organics. The composting program follows rigorous operational, monitoring, and sampling protocols and follows the standards set forth by the US Composting Council (USCC).

Leaves, Grass, & Branches:
Green waste materials may be mixed together but may not include dirt, rock, trash or any other non-compostable material. Construction lumber, furniture, pallets, plywood or wood scraps that have been manufactured in any manner are not accepted for composting. Please see prices chart for current incoming rates.

Soil Products:
We sell our compost and potting soil in 18 lb bags and loose by the ton

Free Residential Food Waste Drop Off

We offer a 6 1/2 gallon sealed gasket and lockable food waste collection bucket for general kitchen use. It has a very tight lid that prevents odors from escaping. It is not designed to be bear proof, but it is very sturdy. Call (970) 429-2880 for details. Food may be dropped off at the landfill during regular business hours without charge. Residential collection can be arranged with a fee from local haulers EverGreen, Zero Waste, & Mountain Waste.

How does Pitkin County's composting program work?

How to Use Our Compost:

Our compost can be used to add extra nutrients and organic matter into your soil. Since our compost contains more Nitrogen than regular dirt, it is not a replacement for topsoil or potting soil. Plants should not be planted in pure compost; it needs to be mixed with your existing soil, or one of our other soil products like topsoil.

For Trees & Shrubs:

Establishment: After digging your planting hole, mix compost with the excavated soil at one (1) part by volume compost to 3 parts by volume soil. Backfill and firm the soil blend around the root ball within the planting hole. Always water thoroughly after planting.

ATTENTION: Lower compost application rates should be used for salt sensitive crops (e.g., conifers)!

For Flower & Vegetable Gardens:

Compost should be uniformly spread over the entire area at an average depth of 1-2 inches and then mixed into the existing soil to a depth of 6-8 inches. Higher application rates of compost may be used if the compost is mixed down to a greater depth. Rake the soil surface smooth prior to seeding or planting. The amended area should be watered thoroughly after planting. Depending on the needs of your garden, add new compost anywhere from once per year to once every 3 years.

ATTENTION: Use less compost for salt sensitive crops (e.g., strawberries). Some crops, like tomatoes, may need a little bit more compost for a nitrogen-rich soil. Using our compost will reduce or eliminate the need for chemical fertilizers - do not over-fertilize - factor the nutrients in our compost into your calculations when deciding whether to use additional amendments on your garden!

For Lawns:

Establishment: Compost should be uniformly spread over the entire area at an average depth of 1-2 inches and then incorporated to a depth of 6-8 inches using a rotary tiller or other similar equipment. Higher application rates of compost may be used if the compost is incorporated to a greater depth. Rake the soil surface smooth prior to seeding, planting or sodding. Always seed, plant or sod during the recommended period of time in your region. The amended area should be watered thoroughly after seeding, sodding or planting.

Maintenance: Our compost can be used as an annual topdressing: an optional maintenance practice on both cool and warm season lawns. This can be done before or after core aeration to reduce compaction and improve moisture holding capacity. Drag or rake compost into the aeration holes. Cool season lawns can be compost top dressed in the early spring or fall. It’s best to apply compost to warm season lawns in the spring just prior to the active growing season. The area should be watered thoroughly after any seeding.

ATTENTION: Using compost will reduce or eliminate the need for additional fertilizer. Adding extra fertilizer may kill your lawn. Request our latest laboratory analysis for the exact nitrogen and phosphorus contents of our compost, and then adjust your fertilizer use accordingly. If you are planting a “Pitkin County Non-Irrigate” or other Native Colorado grass seed mix, you will not need additional fertilizer
