Hanson Commercial Storage

Seed Storage

Hanson Panels are used in so many bulk storage markets it's a challenge to list them all. Below are the profile pictures of one of our customers. This Seed Company used an existing building to store bulk Edible Bean seed. What can you store in one of your old buildings? This bunker was installed by the customer to save money, as you can see they did an exceptional job. Contact us if you are thinking about installing your own bunker silo and we can set you up, it is easy.


Our Compost Bunkers are used for various mammals and livestock:

Due to the proposed FDA rule change effective April 27, 2009 farmers will no longer be able to send their dead cattle over 30 months of age to rendering plants. Most dairy herds lose cows well past this 30 month mandate. Hanson Silo Company is helping our dairy customer by providing precast composting systems. With several options of Bunker Panel sizes available and 2 composting systems in use, we are happy to offer another solution to the large and small farms we serve. Contact us for more information.

Why Composting is a Good Choice


Environmentally sound

Cost effective

Easy to accomplish

Will I have problems with odor?
No. A properly managed compost pile with enough bulking agent will not produce offensive odors. Farmer cooperators in three Minnesota demonstration projects found that the layer of sawdust or bedding on top of the pile greatly reduced odor and, once the compost heated up, offensive odors were essentially absent. However, turning the pile may produce odors.

Will the composting piles attract flies and rodents?
No. Flies are not a problem because internal temperatures above 130F will kill existing fly larvae. Also, when piles are covered by at least 12 inches of bulking agent, flies and rodents are not attracted to the area. If manure is used in the pile and not covered adequately by a bulking agent, some flies may be present on the surface but they will not be able to reproduce.

Will the compost spread diseases?
No. The high temperatures of proper composting will destroy most harmful bacteria and viruses associated with livestock. Viruses that cause avian influenza, Newcastle disease and pseudo rabies are completely inactivated by the end of the second heat cycle. Bacteria such as Salmonella enteritidis, Pasteurella multocida, Erysipelas rhusiopathiae and Salmonella cholerasuis will be successfully destroyed by the composting process.

Will composting work with all animals?
Yes. Poultry, swine, sheep, and goats can all be composted without a permit. The Minnesota Board of Animal Health regulations require a permit for cattle. With larger animals such as sows and larger cattle, some of their large bones may take longer to decompose than with smaller animals. These bones can be removed from the finished compost and returned to an active pile for further composting. Note that while any species can be composted, Minnesota Board of Animal Health regulations do not allow composting of any animals that died from anthrax or toxic materials.

Will I recognize animal parts in the compost when I turn it?
No. Farmer cooperators in three Minnesota demonstration projects found that when the piles were ready for the first turning, the only recognizable parts were larger bones. These bones were rubbery and decalcified, and could be broken easily. There were even fewer after the second turning.

Is composting costly?
No. The main cost is in building a composting structure. Some farmers in Minnesota have renovated existing buildings for little cost. Another cost may be a front-end or skid steer loader to handle the mortalities and compost. The only on-going cost is the bulking agent and the skid steer. Your farm may have bulking agents (such as straw, litter, bedding, or corn stalks) available at no cost. If not, you will have to purchase bulking agent. This cost should be minimal.

Will composting take a lot of labor?
No. The labor involved is minimal, consisting of placing any new mortalities in the bin every day and covering them with bulking agent, checking the temperature of the pile every day, moving the pile between the primary and secondary stages of composting, and moving the finished compost to storage. One Minnesota farmer who had a composting demonstration site on his farm estimated that it took about ten minutes each day to manage.

Are there uses for the compost when it's done?
Yes. The finished compost can be used in your next compost pile to replace part of the bulking agent and provide a large microbial population right away. It can also be spread on crop fields to provide beneficial organic matter and nutrients to the soil and the crops.

Can composting be done in the winter in Minnesota?
Yes. Active piles will continue to heat during the winter. New piles should not be started during the winter unless active, hot compost is available as the bulking agent.

Can any size operation use composting?
Yes. However, if small operations use a seasonal livestock production cycle they may not want to start in the winter.

Can varmints be a problem around the compost pile?
Yes. Visiting dogs, coyotes, raccoon, skunk and fox can become problems. A very hot and active compost pile where the carcasses are adequately covered is the best solution.
