Cool Organics Recycling Demos
University of St. Thomas Feeds Coffee Grounds to Red Wigglers
The University of St. Thomas recycles most of its organics with the Food to Farms program, where food scraps are fed to farm animals. As for the coffee grounds that the animals do not particularly like, they are recycled using worm composting.
Merriam Station Community Garden Repairs Urban Soil
Merriam Station Community Garden composted over 28,000 pounds of organics from businesses between October 2012-2013, demonstrating a capacity to handle some organics locally, while benefitting the garden.
Merriam Station Community Garden
Celebrating 28,000+ lbs of Recycled Organics!
October 25 – It’s our anniversary today! In an effort to keep valuable soil-building resources in the neighborhood, over the past year, Merriam Station Community Garden and some local businesses have proven our capacity to recycle 28,000+ pounds of organics. We did this maintaining a hot compost pile using feedstock including coffee grounds collected from businesses. We also tried sheet composting/lasagna gardening experiments that proved to be effective. Next we’ll be working with the Universtiy of St. Thomas to recycle these coffee grounds with worm composting.

I am new to worm composting. I’ve read about it and have seen some very cool demonstrations. For example, at the University of St. Thomas, they recycle coffee grounds with vermiculture.
Do an Internet search on “worm composting” or vermiculture and you’ll find lots of tips for getting your worm bin started. For example:

Once I decided to compost kitchen scraps in my backyard, I turned to the Internet where I learned that my pile would need:
- Brown/old/dry/carbon material such as leaves or shredded newspapers
- Fresh green material such as vegetable scraps
- Air created by turning or poking holes in the pile
- Water to achieve the consistency of a wrung out sponge
I learned about what to include in the pile and what to exclude, such as meat, fish and cheese. Wiggly Worm became my hero and the cheerful singing of “Composting, It’s a Way to Recycle!” could be heard for blocks.
Here’s a taste of the kind of resources that helped me get started:
I’ve since discovered these videos that answer common questions:
Choosing a Bin
A choice of compost bins ranging from 35-200+ dollars was overwhelming and could have derailed my plans. Fortunately, it didn’t matter. One day, the thought of pitching carrot peels was just too distasteful. I could not do it. Seeing me stash them in a coffee can and probably being somewhat alarmed, the next day Brian brought home a county-subsidized standard-issue black plastic compost bin for the backyard. It works great.
Space limitations might require the consideration of something like the Envirocycle, a tumbler with a small footprint. Or consider vermiculture.
Barriers Can be Overcome
Trust that your concerns about composting, whatever they are, can be addressed. Set your doubts aside, focus on the reasons why composting is a good idea and make a decision to do the right thing. Know that certain problems, such as attracting pests or bad smells, can be totally avoided by sticking to a few simple guidelines. Once committed to the goal, your fears can be put into perspective and problems that do arise can be solved with simple troubleshooting steps.
I’ll leave you with some composting tips:
- Line your kitchen compost bucket with newspaper. It will keep the container clean and provide a carbon source to your compost pile.
- Shred leaves with a lawnmower and keep some near the compost pile.
- Give food scraps an extra whack with a knife before adding them to your kitchen compost bucket.
- Add a bucket of leaves or other carbon source to the pile whenever you add a bucket of food scraps.
- Don’t worry too much about the exact carbon/nitrogen ratio unless you would enjoy it.
- When setting up the pile, start with a layer of sticks on the bottom to encourage air flow.
- Cover the bottom of the bin with chicken wire to deter animals from burrowing. I didn’t do this and do not consider our resident chipmunk to be too much of a pest.
- Use compostable wax paper in place of plastic wrap.
- If you don’t bring a reusable container, always ask for compostable carry-out packaging at restaurants. If they do not have it, request tinfoil, which can be recycled.
- Pick a date to set up your compost bin.
