Just wanted to drop you a note and tell you how much of a fan I am of your compost bins. I have tried many
different kinds of compost bins over the years and yours by far is the best of the best! It is the simplest
of all to put together, the simplest to fill, empty, and move if necessary. It is in my opinion the best, hands
down. I have four of them and I just keep filling the first one till it is full then start on the next one.
I have a huge magnolia tree in my yard which puts out a massive amount of large leaves. Until I got your
composter, it was a constant battle to keep up with it. Now, I just fill up a bin and at the end of a year,
I have a beautiful pile of rich organic black gold.
I think your design is the most basic and easiest to use. I can just lift the bin right off the pile and have
full access to all of the composted material. Then, I just sit the bin in a new spot and start all over again.
In the spring, I sift the composted material into a
wheelbarrow. Whatever doesn't make it through the sifter, goes back into the first bin to continue decaying.
It is a great system. Thanks again!
Sincerely, Carter Davis, Ashland VA.
Dear Covered Bridge Organic,
I filled both composters with yard thatch. We had about 40 cubic feet to start with combined with 10 cubic
feet of wet leaves. We added small amounts of kitchen vegetable waste each week. Here in El Paso, Texas,
we have a cool enough winter that the grass does not need mowing from mid-November to early-March.
Across the winter, nights often get to mid-30's and occasionally to the teens. Winter days run from mid-40's
to low 60's. I noticed that by early-February, the contents had compacted/composted down to about 60% full.
As the weather warmed up (our days are now about 80) the composing noticeably accelerated. I've added about
another 40 cubic feet of lawn clippings since March 1st. To date we have sent no yard waste to the landfill.
I stir both composters with a pitchfork about every 10 days in winter and every 5 days from March 1st.
El Paso gets 8" of rainfall per year. We are at 3,500' so the climate is "high desert" which means very dry, a
bit less hot (than further north places like Phoenix and Tucson ) and with cool nights. Hence, I water about
once every 5 to 10 days, hose full blast until I see water running out of the air vents... about 4 minutes per
bin. My guess is that I add about 40 gallons per bin.
Our bins are located in a small fenced in utility area to the south side of the house. They are about 23' from
the side of the house. Never had a noxious odor problem - just a puff when the lid is removed and it is not as
nice as aftershave, but not bad at all. We see lots of tiny bugs (look like no-see-ums) flying around inside
but they don't leave the bins. We see lots of bugs creeping through the clippings just doing their part of the
process. The bins get about 6 hours of direct sun in the summer and 4 hours in the winter.
I've pulled out and used about 5 cubic feet of compost, which was the entire finished production from one bin -
we added the initial 18 cubic feet in November and then added no further to one bin. This weekend I plan to
move the best compost from our full bin to what has become our "finished product bin". Much of what is in our
"starting bin" is already well-composted and I would estimate we have another 10 cf of ready compost. I used
the 5 cubic feet compost to till into our small garden. The next batch will be used
as a kind of mulch over the garden to hold moisture. If we have enough I plan to use the remainder to repair
some bad spots on the lawn. We haven't tried any composting accelerators and it seems that our balance of input
capacity and output demand is about in-balance. If we had bought a single bin, I would probably try an accelerator.
We haven't saved any money as our trash pick up is a part of the water and sewer bill. As mentioned in my opinions
entry, If all goes well I'll try to get our eco-czar interested in a city-wide program. Composting has saved us some
effort in that lawn clippings are easily dumped into the bin. We are saved the bagging and carting the bags to the
curb. We also add leaves that are blown into the pool and picked up by the filters - mostly palm fronds. We added
maybe 4 cubic feet of these since November, and another 5 cubic feet of plant trimmings.
Our experience has been challenge-free. I initially located the bins in the back corner of our lot, but moved them
in February to the spot near the garden, which is a major point of compost use, and is much handier for dumping lawn
clippings. The design seems about perfect to me; capacity, performance, ruggedness, and price. I plan to drill
center holes in the lids as you have done with your latest design. To me, having two bins has been very handy in
managing inputs and outputs and you might try a stronger suggestion of this in your marketing - I think most people
will be happier with two bins.
Advice would be to try it as I'm fairly sure that most users will see a very nice benefit for a reasonable expense.
It just feels good to be doing something that benefits the ecology. Our 12-year old is fairly stoked about that too.
Happy Composting, Rich Chumsae, El Paso TX
If you want to maximize the diversion rate up to the 800# per year potential, residents need a unit
that can handle the volume. Field trials rank the Covered Bridge bin as the largest maximum capacity
and easiest to use, with the fastest composting and highest sustained internal temperatures. Contact
us to find out how Covered Bridge Organic can help make your community recycling program a success.

We can ship 96 basic units to the pallet in bulk quantities to a community by common carrier or directly
to a resident's front porch via UPS from our secure server.
High post-consumer resin (PCR) content is important to us. This feature, along with its durability and
adjustability, has led us to the Covered Bridge Composter as a cost-effective bin to distribute in our program.

We have now sold over 2,000 bins with no returns and no complaints. The large capacity maximizes our
yardwaste diversion, the simple design is very user friendly and the booklet that comes with the bins is
easy to understand. We now have a documented 23% reduction in leaf collections. Thank you for your exceptional
service and your continued support with our program. We look forward to many more years of working together.

The Ashtabula County Solid Waste Management District was very satisfied with the residents' response and results
of the District's first backyard composting program. Covered Bridge provided the product, and more importantly,
a strong educational component that made this program a success. Covered Bridge provided the necessary resources
which were not available at the District Office.
