  • What goes in the yard debris cart?

    The yard debris cart is where you can place grass and clippings from your yard to recycle them into compost.

    The Master Composter Recycler Program offers FREE workshops and trainings on backyard composting, worm-bin composting, recycling, green cleaning, and other waste-reduction techniques. For more information about this program and to sign up for a workshop, visit our Master Composter Recycler pages or email

    What goes in the cart:

    Leaves, grass, brush, or woody prunings.

    If you use bags instead of, or in addition to, your yard debris cart, please use only compostable, double walled kraft bags sold for this purpose. Brush bundles must be less than 1 foot in diameter and 5 feet in length. Tie with twine or string, no wire please. Loose yard debris is not accepted.

    There are weight limits for the carts. For more information, please call Waste Connections at 360.892.5370, visit or email

    Seasonal items:

    • In Autumn, pumpkins are accepted with the candles removed.
    • Christmas trees can be placed in your cart. Cut them into sections no longer than 5 feet and remove all tinsel, decorations and lights. No flocked trees are accepted.
  • How to compost

    Composting is a way to turn your yard and kitchen wastes into part of nature’s natural cycle of decomposition. Composting is a great way to reduce our contribution to landfills and climate changing gasses while producing a wonderful soil amendment for yards and gardens.

    We offer workshops and demonstrations on how to feed the earth rather than the landfill.

    Backyard Composting

    There are many systems for composting yard and kitchen waste in your backyard. You can visit one of our composting demonstration sites to see various bins and systems in use. If you want to virtually explore some options for backyard composting systems this website is a helpful resource.

    The two basic backyard composting methods are fast— batch or hot composting, and slow— add as you go or cold composting. Mother nature doesn’t care which one you use. But you might! With the faster hot composting method, the end product can be higher quality— but the amount of work needed to turn and monitor your pile is more. With cold composting, not as much work is needed, but it can take several months to a year to get usable compost.

    SMART is an acronym for the compost factors you should pay attention to for best results:


    The size of your pile and the pieces you put in it. Your pile should be at least 3 x 3 x 3 feet in volume (for a hot pile). Your woody pieces of material should be chopped up to less than 2″ in diameter.


    Keep the pile moist as a wrung out sponge. You can mist it with a hose as you add new material.


    Turn your compost occasionally. You want oxygen to get into the pile, and to get the materials mixed. Serious composters try to get the pile hot — and turn it once the temperature drops.


    The ratio of “browns” to “greens” should be an average of Carbon/Nitrogen 30:1. An easy way to measure this is to go by volume — and use 1:1. One unit of brown to one of green. An easy way to remember this is “equal parts of green and brown help to break the compost down.”


    Turn your “garbage” into black gold!

    Here are some other great resources

    Composting Using Redworms

    There is great information on the web about composting with worms. Here are some links to resources we find helpful:

    Red wigglers (Eisenia fetida) are the worm of choice for home vermicomposting. There are a number of local resources in the Clark County area to purchase redworms. It’s always a good idea to call ahead for availability and pricing. One pound is typically a good amount to start a worm bin with.

    If you want to purchase redworms elsewhere, we recommend you enter “buy redworms” in your search engine to find the best source and price for you.

    Happy Composting!

  • Become a Master Composter / Recycler (MCR)

    If composting and recycling interest you, you want a sustainable future, and to be part of a great community, consider becoming a Master Composter Recycler. The volunteer training provides you with the tools and knowledge to build a hot compost pile, tend a worm bin and reduce waste.

    Master Composter Recyclers attend an annual FREE 10-session course that explores:  backyard composting, vermicomposting, recycling, sustainable living, green cleaning, and more. Participants then share what they learn with the Clark County community. Master Composter Recyclers “payback” their training with community service hours. They represent the program at community events such as fairs and farmers markets; teach and host workshops and lectures; grow redworms for wormshops; maintain compost demonstration sites; and share their knowledge with neighbors and community groups.

    Applications are being accepted now for the 2019 MCR training. Classes are scheduled for Wednesday evenings, January 23 – March 27, 2019. If you are interested in getting more hands on experience with composting and recycling, check out our workshops
