Here’s the question – is it better to compost badly than not to compost at all?
This question has been on my mind lately. I haven’t had the time to get out to my own compost as much as I’d like and I’ve lost a valued helper at one of the schools so that compost isn’t getting the attention it used to get. So am I thinking I’m doing a good thing with my piles of organic waste when actually I’m not? If I’m not getting out there and getting air into the compost am I doing more harm than good?
The problem is this – when you are composting aerobically (with air) everything is fine. The problem with decomposing organic waste occurs when it decomposes anaerobically (without air) as is assumed to be the case when organics go to landfill. Anaerobic compost produces methane. Great if you’ve got some kind of method to capture the methane and use it as an energy source, bad if it’s heading on out into the atmosphere. Methane is a significant contributor to green house gas emissions. That’s why people object to methane producing cows and why some people object to composting.
So how can we make sure we are doing more good than bad? If you aren’t a regular compost turner then keep your compost simple and the balance right. Here’s what I’m thinking:
- Don’t put in dinner leftovers, any meat, fats or bread.
- Get a compost bin that has an open base to encourage worms in there to do the aerating for you.
- Don’t let your bin dry out. Keep it moist, this will keep all the good bacteria alive and working.
- Cover all of your kitchen scraps with dry leaves or shredded newspaper. This will keep your compost balanced.
- Turn it when you can.
My conclusion is that it’s still better to compost badly than not to compost at all. When organics go to landfill we have nothing except more green house gas emissions. Even if we are a little lax with our composting we still end up with a nutrient rich compost at some point. And we encourage other kinds of soil life. What do you think?
