My father grew up on a farm and I remember seeing his devotion to our garden as I was growing up. We had a compost pile in our backyard about the size of a small car. Each fall the leaves from our oversized yard became the base for the compost pile and we had a large can in the kitchen that scraps were thrown into and sent out to the compost pile. I remember wondering why snow never accumulated on it until my father explained the process and showed me by sticking a rod in it and letting me feel the heat it created.

Now as composting is the newest program to complement a sustainability program that includes reducing, reusing and recycling, I remember the lessons of my youth.  The most important issues are watching what you put into the compost pile and what you are going to do with all the compostable matter you collect – after all, not everyone can have a compost pile the size of a small car.

You can compost pretty much anything that you can eat or use in cooking. The best compostable items are vegetables and fruits; they decay or decompose the quickest. Meats, fish and oily foods like cheese or salad dressings take longer to compost and can create problems with odors and attracting pest.

Composting has its challenges now, as we are really in the early stages of this trend.  You read numerous success stories that are mostly available on the west and east coast, but the reality is that there is limited commercial composting available. Commercial haulers have not really expanded to providing it, and many local programs are small by proportion.

As an operator it requires a true commitment and the ability to work with programs that are still in the testing and development stages. Your involvement requires a small expense to get started. You will need to buy some type of trash containers (32 Gallon) with lids to store the compostable materials. Once you have collected the compostable waste, the transportation to the site may be your responsibility and that is probably the biggest challenge.

One of the benefits of composting programs is that operators see what food is being thrown away and why. Was too much ordered and it spoiled? Was too much prepared? Are the prep people trimming vegetables more than is required? When an evaluation of the compostable items is examined, it can offer valuable information that commonly results in taking another look, reducing and creating savings in purchases.

Large facilities like college or corporate campuses may have the space to compost their own materials, thereby reducing the waste hauling charges.  They can then have the grounds maintenance department use the resulting product in their programs, saving money on that aspect of their business as well.  Meeting with your staff and explaining the goals of your program can generate a lot of excitement. Some have even held competitions to measure the success. Just by purchasing a scale you can have a competition as to who can collect the most by simply weighing their containers. 

With the popularity of sustainability and the publicity it has created, composting in commercial foodservice facilities will only be hindered by our creativity in dealing with the compostable material.

A great example of a successful composting program is at the University of New Hampshire. They have had a program going since 2003 and peaked in 2005 by composting 268,000 Lbs of food waste that was generated from all their foodservice outlets. They are collecting the waste from all of their kitchen prep areas (pre-consumer waste) and also collecting the food waste at the end of meals (post-consumer waste). There program is very well thought out and they are utilizing many of the latest techniques including grinding and pulping the food waste to reduce the volume. The University has a 350 acre agronomy research facility that is the site for their composting. They sell the compost rich soil at local stores and also sell directly from their own facility.

In the Baltimore/Washington area there are 2 firms that are offering composting to restaurants, grocery stores, institutions and commercial properties. They have great websites with lots of useful information.

In the early 90’s I was managing a cafeteria style restaurant that was struggling. The owners partnered with another concept and we remodeled and reopened as a buffet style restaurant. The business quadrupled, we were serving around 13,000 customers a week and life had changed as we knew it. Amongst the numerous issues, our trash hauling needs also quadrupled and we were using tremendous amounts of food.

We were using 150 cases of #10 can products and 100 four-gallon buckets of different products a week. The #10 cans were taking up a tremendous amount of space in our dumpsters and the plastic buckets were piling up. The trash hauler really had no program for commercial recycling and only suggested we get a compactor to help the situation. Not really liking the idea we went ahead and bought a can crusher to put in the kitchen and that helped reduce the volume with the #10 cans. During a meeting with the local senior center they asked me if we could save #10 cans for them as during the holidays they decorate them with cloth and other country-like materials and sold them as toilet paper holders to store extra toilet paper in the bathroom. They claimed they could sell lots of them at their Christmas Bazaars’. 

If you want to get involved in reducing your waste, it takes some innovation and thinking outside the box.

The 4 gallon buckets were another issue. I and everyone else that worked at the restaurant or I knew had as many as they would ever use. Every once in a while someone would come in the middle of the night and think they are stealing the buckets, we just hoped they were using them. My wife and I actually saw some of them at a yard sale being sold for a quarter. After a few months a customer knowing of our excessive bucket accumulation informed me of a non-profit organization that collected old paint and mixed them together and donated the paint to help people paint their homes. We gave them as many as they could reuse.

One evening a staff member informed that there were a couple of men out back pulling trash out of our dumpster. When I approached them, they informed me that they had a hog farm and were taking the discarded food to feed to their hogs. The idea sounded like a good way to recycle our food waste.  We eventually started placing empty 4 gallon buckets at the prep stations and the staff was throwing trimmings and scraps into the buckets and they would come by each evening to pick up the buckets for their hogs.

I started with these examples because as I joined the “sustainability movement,” I realized that our efforts to watch our waste fell into the three R’s we hear so much about nowadays:  Reduce, Reuse, and Recycle.

The industry has developed equipment to assist with reducing the volumes of waste. Pulpers have been around for years and come in different sizes. They basically grind the waste thus reducing the volume.   There is also equipment to remove the water from the pulped waste which further reduces the volume. Finally, in just recent years equipment has been developed to dehydrate the pulped material that further reduces the volume. These methods all come with costs and the larger the operation the higher the cost.

Another idea is Composting, but that’s a topic for another day.
