Frequently Asked Questions

What is Grass Clipping Silage?

Silage is a fermented, high-moisture fodder that can be free fed to ruminants (cud-chewing animals) like camels, cattle, sheep, buffalo, elk, deer, antelope, goats and the list goes on and on. Other animals (like horses) must be regulated more closely only offering an exact feed ration to prevent overeating and bloating.

Grass Clipping Silage therefor is the name that  CEO Todd Graus (BioPac'r) created to describe a commodity made from the clippings of golf course, lawn or turf grasses (ie. Poa species).

Who are the primary users of a BioPac'r?
Landscapers, Golf Courses, Sod growing companies and anyone in that manages Turfgrass are all benefiting from reducing landfill trips and turning their clippings into a profitable cattle silage.  Landfills benefit because they no longer have to handle these clippings.
How does a BioPac'r™ Save my company Money?

If you are a landscaper, the BioPac'r™ will save you multiple trips to the landfill or your dump site each week. Unloading 3-5 pickup loads of lawn clippings only takes 30 seconds. A BioPac'r™ could pay for itself in the first year by saving landfill fees and labor charges alone. Start producing Lawn Clipping Silage™ that YCC will help you sell by brokering the silage to livestock operators on your behalf.
Our Savings Calculator will project your estimated annual savings then add the revenue of selling 1-ton silage bales and you can see an even brighter future for your company.

Can anyone become a Distributor of BioPacr?

In our model, Distributors are expected to be the financiers of floor models and not necessarily the front line sales force.  Distributors purchase and provide the floor models to Dealers that can’t otherwise afford to have a display model on hand.  Potential BioPac'r  distributors should already have a dealer network in place or 110% committed to establishing a dealer network in which to place your inventory.  Dealers are mainly comprised of lawn mower or small engine repair shops already carrying commercial lawn equipment like Walker, Toro, Grass Hopper, Exmark, John Deere, etc. There several other types of Wholesale businesses that can become a BioPac'r Distributor with an exclusive territory.  Feel free to contact us if you are interested.


Distributors provide the support to help dealers become successful.

We compress our clippings at the end of each, Why can we only make 1400 lb bags?

Back in 2014 when we were working on our 5th Prototype, we went to the Walker Mower's manufacturing plant in Fort Collins, Colorado.  They had offered to us their grass clippings that were being harvested that day.  When we got there we off loaded all the clippings we could.  We would fill the compaction chamber full and compress, fill and compress until we were at what we thought was the max capacity.  The next day before packaging we weighted the Pac'r and was surprised the content was only 1400 pounds, 600 lbs short of our goal.  The next morning we cycled the hydraulics one last time prior to packaging and was shocked to obtain an additional 2 feet of space!  It occurred to me that the resting period between cycles was important to purge air from the intertwining of the grass clippings.  The process of purging the air trapped in and around the clippings is like air escaping from an air mattress.  No matter how much you push, the air can only come out on the valve stem so fast.


How is Lawn Clipping Silage™ Made?

Silage production can only be carried out under an oxygen-free (anaerobic) environment in order to preserve nutrient quality and provide a produce with a long shelf life (4 Years). As the lawns are being mowed, clippings are dumped into the BioPac'r™ where they are compressed to remove oxygen. At the end of the day the user will transfer the compressed loaf into our specialized silage bags. The bag top is twisted like a bread bag forming an airtight bag. Next, the remaining oxygen is used up in the production of heat, once the heat is gone (24 hrs.) the inside of the bag is oxygen free. Now the bag is in an anaerobic state and the pickling process can begin.  Twenty-eight (28) days later, you have Lawn Clipping Silage™ .

My lawns are sprayed with fertilizers and weed killers throughout the season, can I make silage from these clippings?

In 1965, Wright's Effect of ensiling on the decomposition of several herbicides. Crop Sci: 455-456) proved that the weed killers that were applied prior to ensiling were degraded by 66% within the first two (2) hours of the process! After 30 days of ensiling current lab equipment can detect markers of herbicides but their sensitive instruments just can't measure any active ingredient.  Again and again, studies confirm that the fermentation process still degrades  lawn chemicals today, just as they did back in the 1960's.  There is no surprise that beef consumers had the same concerns back then with as some have today.  The difference is that back then the issue was the cancer causing DDT and today lawn companies use the non-cancer causing 2,4-D found at the local hardware store.  DDT was 1000 times more persistent (12 years) then any lawn pesticide used today (2,4-D is 10 days) (NIH).

In the Journal of Science, Food and Agriculture research titled DEGRADATION OF COMMERCIAL DDT IN SILAGE, August1969,Vol. 20) shows that ensiling breaks down pesticides and nothing in nature has changed since the 60's to invalidate this claim.

Do you make a smaller BioPac'r?
When we looked into a smaller unit, the livestock owners found 1000 lb. bags to be too inefficient for their use. There was also a financial consideration, the cost to make the Pac’r Bags is $25 whether it was a 1000 lb. capacity bag or a 2000 lb. bag. And last, for marketing purposes, livestock people think in terms of tons and dry matter equivalent. One ton (2000 lbs.) of Grass Clipping Silage is a wet feed and has the same weight of dry matter as a large round bale of alfalfa.
Is there a recommended procedure to fill the BioPac'r?

1. We would dump the grass clippings into a bulk bag or on a small tarp and at the end of each property we would dump the bag into the Pac’r and compress the clippings before moving onto the next yard.

2. Move on to the next property, keeping the pressure on the load until you are ready to fill the chamber again, probably at the end of mowing the next property and cycle the compaction stroke once again.

3. Once you run out of space, it's ready to package.

4. If possible, Leave the clippings in the compactor overnight under pressure and package the next morning allowing most of the oxygen to be purged overnight.

5. Before packaging, cycle the Pac’r one more time to eliminate pore space. If you gain a few more feet of space, add some more grass.

Note: having this much extra space the next morning means you tried to compact too much, too fast the previous day. Which is the result of waiting until the end of the day to compact two or more crews at once. Doesn’t work this way. Trapped air inside the loaf needs 15-20 minutes between cycles to purge to obtain a tight pack. This is why we recommend you pack curbside at the end of each property on the fly.

What's a Lawn Harvester?
A "Lawn Harvester™" is a Trade Marked name that Yellowstone Compact & Commodities coined to be used in place of phrases like "the lawn mowers, the grass cutters, the lawn mower guys, etc.," meaning those who mow the lawn. A "Lawn Harvester™" is a name that can be used (legally) if your company has purchased a BioPac'r™ to produce Lawn Clipping Silage™ and if are using the YCC Sequentially coded Zip Ties to close off the Bio Liners.
