Since coming back from holidays in Thailand, I have been researching the subjects; worm farms, Bokashi buckets and recycling doggy poo. I wanted to see if I could find answers to questions I have yet to fully understand.
The main issue was around a couple of comments friends emailed me with regards to my post ‘doggy poo loo’. Here is one such comment: “…doggy poo being picked up via degradable doggy poo bags and put into the garbage (will decompose at tip)……”
It was the comment of doggy poo or for that matter any organic waste decomposing at the tip that got me thinking. My initial reaction was “waste decomposing at the tip is not the best environmental way to handle waste” but I have to be honest that I didn’t know exactly why. So hence the research began.
From this website I learnt that because landfill is underground and airtight the process of waste being broken down by the absence of oxygen is called anaerobic. Apparently the byproduct of this anaerobic breakdown is landfill gas, which contains approximately 50 percent methane and 50 percent carbon dioxide with small amounts of nitrogen and oxygen.
According to this website and I quote “Methane (CH4) is a greenhouse gas that remains in the atmosphere for approximately 9-15 years. Methane is over 20 times more effective in trapping heat in the atmosphere than carbon dioxide (CO2).”
If the brake down of waste in landfill creates Methane ‘greenhouse gas’, is my worm farm any better as a waste management system at home?
And I quote this article “….Composting sounds easy – lift the lid, chuck the stuff in and forget. But you need to turn it (poke it around and lift it a bit) to get the air in there – otherwise you’re a domestic methane production facility (and that’s as bad as sending scraps to landfill).”
Though this was referring to composting I think it may still refer to worm farms. Hence my new lesson from this week’s research is basically I need to aerate my worm farm. I will do this every time I add new food scraps from now on! Of course doing this very gently as I do not want to hurt any of my little wormy friends.
