I recently had the opportunity to tour an industrial scale composting operation. I am a huge compost geek so I was pretty excited. I’ve seen a lot of piles in my day, but nothing like this. This facility, Community Recycling (a division of Crown Disposal), processes food scraps and organic wastes from most of the major grocery store chains in Southern California. They also collect food scraps from restaurants and other food vendors in the region as well as operate a recycling facility for metals, plastics, wood, paper, yard trimmings and anything else they can find a market for or a way to keep out of the landfill. I must say it was pretty impressive. But the most exciting part of course was the compost.
There were literally mountains of compost called windrows in rows perhaps twenty feet high by several hundred feet long. It’s a large scale operation with not just one windrow but dozens of them. And this is all stuff that otherwise would end up in landfills. Of course we should be composting all of our organic wastes close to home, but the sad truth is that a lot of this lovely organic material gets thrown away instead of returned to the earth. So I am glad that enterprises such as this exist.
When vegetables are going to go bad at the grocery store, they get tossed in a bin bound for these vast fields of degrading organic matter. The interesting part is that they get tossed in, plastic and all. There are bagged carrots, bagged salad mixes, plastic wrapped heads of cauliflower, all together. The compost windrows are just littered with plastic as you can see. Nothing like my backyard compost, where I would never allow any plastic or so much as a stray rubber band. On a commercial scale, they find it easier to sort the plastic out at the end of the composting process. Just how they do that, they won’t say–apparently it’s proprietary. But we got to drive around the hundreds of acres of compost and see the process for ourselves, start to finish. [Mr. Homegrown here: plastic combined with organics is one of the big problems in the world of municipal waste.]
The food waste is blended with wood chips or wood ‘fines’ as needed. Huge windrow machines straddle and churn the piles. They look like something out of Star Wars. Several months later the finished compost is sold to farmers. Community Recycling is a totally vertically integrated operation so of course they farm a little too–organic almonds, some row crops and some forage crops. That way, if they have too much compost on their hands at one time, they can always put it on their own land. The soil looked pretty good to me. I got to traipse around and get my hands in the earth. They also raise wild turkeys and other native birds to be released into the wild. It is part of a habitat and wildlife restoration project they are involved in.
This was better than any amusement park I’ve ever been too. I mean, they have compost, weird looking wild animals- yes, turkeys are very weird looking, organic almonds, a recycling facility and did I mention the mountains of compost? I’m pictured below, the happy queen of the compost heap.
