What is curbside composting?
Curbside composting is a way to recycle food scraps and compostable materials through a pickup service rather than at home. Our curbside composting program utilizes a bucket "swap" to ensure buckets are cleaned each week while eliminating the need for bin liners.

Instead of throwing food scraps, bones and meats, seashells, paper products, and other compostable material into the trash, households use a 6-gallon white Garbage to Garden bucket with snap-tight lid. Each week on garbage day, subscribers put the bucket on the curb, and Garbage to Garden swaps the bucket for a clean one. Participants may receive as much as 1 bag of finished compost a week, upon request. The compost is made at Benson Farm in Gorham (it is the "Surf N Turf" blend) and is approved by MOFGA for organic gardening and crop production.

    Where should I keep my bucket? How big is it?
    The bucket is 6-gallons and is 16" tall by 14.5" wide. Most participants keep their bucket in the kitchen, either under a sink or in a cabinet or closet.

    Alternatively, some participants collect their scraps in a smaller containers next to their sink counter compost bin, bowl, or tupperware Participants also leave their bucket in their garage, closets, and porches.
    What can I put in my bucket?
    If it Grows, it Goes!
    All food scraps! This includes:
  • Vegetables, fruit, citrus, bread
  • Cooked & raw food
  • Pits, peels, shells, bones & seeds
  • Meat, dairy & bread
  • Coffee grounds, filters and tea bags (without the staple)
  • Grass clippings, leaves, brush (thinner than a pencil), and other inert organic debris not treated with pesticides
  • Clean, non-glossy paper
  • Napkins, food-soiled paper products, wax paper, muffin liners
  • Hair & laundry lint
  • Cooking oil, fat & grease (collect cooking oil in a separate container with a lid and place it next to your bucket on garbage day. We'll bring it to Maine Standard Biofuels for recycling into fuel & soap!)

  • Plastics and Styrofoam
  • Paper coated with plastic or foil
  • Chemicals or pesticides
  • Metals
  • Glass
  • Pet Waste and Diapers
  • Any inorganic material
  • Plastic wrap, twist ties, stickers, staples, tin foil, condiment packets & rubber bands
  • Brush or sticks (thicker than a pencil)
  • What do you mean by organic?
    In soil terms, the word "organic" is used differently than it is when classifying produce at the supermarket. When we say we can accept anything "organic," we mean anything that was once alive.

    In a similar vein, any compost that is marked as "organic" simply means it is made from materials that were once alive and have decomposed. Fertilizer or soil that is not marked as organic may mean that parts of it were derived from synthetic inputs or created in a lab.

    The finished compost that Garbage to Garden delivers back to you is approved by MOFGA for organic gardening and crop production - so food grown using our compost may be "organic" in the supermarket sense, too!

    Do you service on holidays? What about during heavy storms?
    As a general rule, we follow the Portland city trash pickup schedules and we service during all federal holidays except Thanksgiving Day, Christmas Day and New Years Day.

    Although Maine can have some unforgiving winter storms, we try to complete service regardless of winter weather. If the storm significantly impacts the Maine coast and we feel there may be a danger to our operators, we may choose to postpone or cancel service due to inclement weather.

    In the event of a holiday or inclement weather cancellation, we will post the service announcement on the front page of the website, in the FAQ (below) and to our social media pages (Facebook and Twitter) along with a direct email to the affected service locations.

    Upcoming Service Changes
    No upcoming planned service changes.
    Can I get extra buckets for a party or event?
    We've got you covered! If you need a few extra buckets for a one-time event at your normal service location, we can drop them off the week before and you can return them the following service day for a one-time charge of $5. Keep in mind that we may need up to 3 days advance notice in order to fulfill your request.

    If you need a last-minute extra bucket for a house party and do not want it to be replaced at the curb, you can purchase a bucket at a bucket pickup location for $5 and put the bucket out on your garbage day. If you would like it to replaced (so that you have extra buckets on hand), give us a call or email and we'll instruct the drivers to pack an extra replacement bucket for you.

    For larger events with substantial food waste, visit our Event Quote request system and we'll help make your event as zero-waste as possible.
    What should I do with used cooking oils?
    Garbage to Garden participants interested in contributing used cooking oils to biofuel production should do the following: fill any plastic, recyclable container with a screw-top lid (or very tight- fitting lid, like a deli container) with used cooking oil and place it on your curb next to your bucket (in a place it will not spill over) on garbage day.

    We bring the cooking oil to Maine Standard Biofuels where it will be refined into biodiesel and Bioheat Home Heating Oil. Also created during the process of refining the waste fats and oils is Wicked Strong Soap, a powerful de-greaser that we use to wash our buckets.

    If you are interested in further reducing your home's carbon footprint, check this out! Garbage to Garden participants receive a 5 cent per gallon discount to heat your home on Bioheat. Contact Maine Standard Biofuel for details.

    Fun fact: on average the Greater Portland area uses over a million gallons of cooking oil a year. Pouring cooking oil down the drain is harmful to your home's pipes as well as plants and wildlife. That's why we help you to recycle it into renewable energy. Renewable energy is better for the environment since it is less energy intensive, creates fewer emissions than fossil fuels, and helps decrease our oil dependency. The Maine Standard Biofuels plant has the capacity to produce up to a million gallons of biodiesel a year, so together we can make a huge difference. Let's make it happen! "
    What should I do with yard waste?

    Garbage To Garden can accept yard waste at our shop at 57 Industrial Way in Portland at all times. Please contact us to schedule your drop-off.

    All yard waste must be bagged in paper garden and leaf bags. Acceptable yard waste includes grass, plant clippings, flower bulbs, and leaves. Small bits of brush or branches up to about 1/4" in diameter and 8" in length (about the size of a #2 pencil) are acceptable as well. We CANNOT accept large branches or pieces of wood, dirt, gravel, rocks, or loose material of any kind.

    Please contact our office for more information by emailing or calling (207) 332-0277. Thank you!

    Do you compost for businesses?

    Do you compost for events?
    We offer on-site composting as well as complete "zero-waste" event waste management to give your big day the green radiance it deserves. From weddings to backyard BBQs to a large-scale festivals, Garbage to Garden has composted at hundreds of events of all sizes. Visit our event page to obtain more information.
    What's in the compost?
    We compost locally with Benson Farm in Gorham, ME, whose special Surf and Turf blend compost is approved by MOFGA for organic gardening and crop production. Surf and Turf is made up of oceanic residuals (things like lobster shells), cow manure and your food scraps!

    The kind of composting that we do is thermophilic - which means our piles sit at temperatures of between 140 and 160 degrees. When piles of compost rest at high temperatures like this for more than five days, they're able to kill most pathogens (things like viruses and fungus that cause diseases).

    What this means is that our composting process is able to break organics down quickly and kill the bad stuff, leaving us the good stuff to use!
    How do I request compost?
    Login to My Account using your email address.

    Under the "Service" section, you can view your upcoming compost drop-off requests and request additional weeks of bagged compost. At this time, you are allowed to request ahead 12 weeks of compost drop-offs.

    For bulk compost, please contact our office.
    How much compost can I get per week?
    Standard residential accounts can request a bag of compost with service every week. We bag our mature, organic compost at our shop, and each bag comes out around 2.5 gallons.
    Can I order additional compost?
    You can order additional compost online through the My Account section. If you would like a few extra bags, you can purchase additional bags or contact our office about bulk pickup or delivery.

    Bulk pickup is the most economical option. We can fill any sized container you provide; typically, people bring 10-20 gallon plastic totes, trash cans, or truck beds with tarps.
    Can I purchase a large delivery of compost?
    Yes! We can deliver up to 2 yards per truck at one time and can arrange larger deliveries. Delivery dates are limited to truck availability and may only be available on certain days of the week; the sooner you can contact us the better.
    What do I do with the empty compost bag?
    We would love to reuse it! After using your compost you can take the white compost bag and place it under your Garbage to Garden bucket on your service day. We'll pick it up when we replace your bucket. Placing it under your full bucket of compost helps to keep it from blowing away.
    I've heard that compost can burn my plants. Do I need to mix your compost with soil or dirt?
    If you are applying the compost to the top layer of a garden, no. Our compost is garden, plant and vegetable ready! We recommend adding a 1/2" layer to the top of the soil, leaving space around plant stems and tree trunks. Then, let the worms do the rest!

    For new garden beds, mix 1 part compost to 2-3 parts topsoil. For further questions on compost use, visit a local garden center or consult Benson Farm at

    Community Events: We partner with numerous events that want to be zero-waste and compost, or that want to showcase curbside composting. Volunteers help us manage sorting stations and/or staff the Garbage to Garden information table & help us spread the word about our service!

    Local Organizations: We partner with various local non-profit organizations to boost their volunteer participation for a certain month or event by offering a free month of service to those who attend. We do this to expand our impact in the community and offer a feel-good way for participants to keep costs low.
