Put yourself in the shoes of a community administrator about to tackle the goal of increasing waste diversion from the landfill. Food scraps are part of the evaluation. The easy solution – composting!
In your community, you’re already managing landscape waste that way, so the infrastructure is in place to harmlessly turn organics into dirt. (And if it isn’t, building a flat composting pad takes relatively minimal time and capital.) Good. Done.
As an administrator, you are about to take the first step of a familiar “5 stage” journey in coming to terms with the reality of establishing your food scrap composting program:
Large-scale food waste composting is the way to reach our diversion goals. Great idea! Let’s do it!
Gee, why does it stink so much?
OK. I’ll tell the public they need to be patient.
Great. The facility is about to try something else to fix the problem. I wish they’d hurry up.
Yeah, um, it’s been 2 years of this, so we’re going to need to stop taking food waste.
No doubt, recovery of food scraps for a “higher and better use” is a good thing and successful source-separated collection and composting programs abound. However, significant odors are a common, persistent side effect from composting on the “large scale” you’ve just undertaken. To paraphrase comedian Ron White, “If odor from a compost facility was music, and the whole town could hear it, the police would tell the facility to turn it down.”
Composters are working to mitigate these nuisances and I do wish them luck. But until the process is improved, maybe the administrator should consider anaerobic digestion as a viable alternative. In many locations the infrastructure is already in place, with trained professionals experienced in managing organics. And the surrounding population accepts the operation, to boot.
But if you’re nonetheless committed to the idea that “compost is king,” you should know that the Washington Organic Recycling Council is holding its Annual Convention in Vancouver, WA on November 19-20, 2013. The theme of the conference is odors related to composting. Space is limited.
