DEEP: Potential Sources of Compost

Potential Sources of Compost in Connecticut

Leaf Compost

{hands holding finished compost} By State regulation, leaves are a mandatory recyclable item which means that they cannot be disposed in a landfill or incinerator.  They must be recycled, and the most common way to recycle leaves is to turn them into compost.  There are now about 100 leaf composting facilities registered with the Connecticut DEEP, most of which are municipally owned and process town generated leaves.  Municipal operations tend only to accept leaves generated by that town, and may also provide small quantities of finished compost to residents for free or at a nominal charge.  There are also several private leaf composting facilities which have been established in response to the demand for purchasing finished compost and for places to recycle leaves.  Private facilities will usually accept leaves from many different sources and have larger quantities of compost available for bulk sale.

Compost Made From Source-Separated Organics

A Word of Advice 

It should be noted that not all compost products are created equal.  Some facilities are better able to process organics because they have specialized equipment such as mechanical turners and screens, or put more time and effort into the composting process, and therefore may have a better quality compost.  Also, some facilities may accept different types of organics resulting in different compost products.  Remember that compost isn't always for sale.  Farmers and municipalities may use all the compost they can produce to spread on crop fields or to use in capitol projects such as ball filed rejuvenation and public works applications.   It is always a good idea to check on compost availability and to visually check the quality of the compost before purchasing bulk quantities.  For a comprehensive listing of available sites, please select the appropriate category below.
