Dog poo turning green – the power of science

Hey Julie,

Thanks for the run down on ScienceOnline and ‘Lend a Paw’ month. 

I completed the survey about my cat’s behaviour, it was quick and easy to do. 

I also liked your stroking video, but I’ll get back to that later, right now I need to tell you how dog poo (I think you usually say ‘poop’ in the USA?) is turning green.

Dog poo is turning green

It’s turning green and it’s thanks to the power of science. Or perhaps it’s the science of power? It’s easy to get confused.

The important bit is that a Melbourne-based entrepreneur, Duncan Chew, received funding in 2012 from the Inspiring Australia strategy for his idea to turn dog waste into energy to light up parks around Australia. Titled Poo Power!, his project is using science to help our communities live more sustainably.

How big is this issue?

In Australia, we have one of the highest incidences of pet ownership in the world with over 60% of households owning a pet. The average dog produces 0.34 kilograms (that’s 0.75 lb) of faeces per day.

Do the maths, and that’s around 1.4 tonnes of dog poo needing to be disposed of DAILY in Australia, which adds up to a colossal 490,000 tonnes each year!

490 MILLION KG!  That’s 1,080,270 MILLION lbs!

(or almost 20 million labradors if you were following my pre-post riddle clues on our Facebook page!)

The USA have more than 20 times the number of dogs as Australia. Just saying.

The issue of dog waste disposal (what I like to call Poo-llution!) is an especially important issue in areas of growing urbanisation, cities with limited park spaces and in light of declining landfill site availability.

Using our love of dogs to brighten the future

The project will see a series of biogas generators turn dog waste into energy for lighting up Melbourne parks, at the same time as engaging audiences on the issue of ‘what is waste?’, and the potential opportunities posed by reassessing waste management practices. 1kg of dog poo will give you about 25-30 litres of raw biogas.

Biogas harvesting is achieved utilising anaerobic digestion (where a bunch of microorganisms break down biodegradable material in the absence of oxygen) to produce a renewable energy source that can be used to power lighting. Or cooking! Imagine having a coffee as your dog runs around the park, while the coffee machine was powered by your dog’s poo!

I’m not talking crap (well, I am)

We know this can work. This kind of project has been implemented previously at ‘Park Spark’ in Cambridge, Massachusetts, near MIT. 

Munich Zoo similarly harness the energy of their animals’ faecal output to help power their operations. Imagine if shelters and other kennel facilities could use this system to reduce their power consumption and expenses? That would be awesome!

Can’t get enough of green dog poo? 

If you’d like to hear more and you happen to be in Melbourne this weekend, a) you should come over to my place, so we can say hi, and b) you can watch Duncan Chew and Melbourne filmmaker James Boldiston talk about the Poo Power! project at 12 midday on Saturday 16 February 2013 in ‘The Big Tent’ at Federation Square as part of the Sustainable Living Festival. Otherwise, you can keep up with further developments at the Poo Power! website. 

I’ll be touching base with you again after I speak at the RSPCA Scientific Seminar. 

Looking forward to having lots to report about animals and the science of positive welfare – more stroking!

Mia

How to make fireworks less upsetting for dogs

(Source)

Hi Mia,

Well #SPARC2013 is over for this year. Great summary and explanation of the value of scientific discourse! Now onto the next big thing!

In just a few hours, the banging, crashing and booming of fireworks will start here in the States. In NYC, R&B Star Usher is "curating" this year’s Fourth of July fireworks (I just like saying the words "curating" and "Usher" in the same sentence). As we discussed last December, a lot of dogs are not fans of loud noises, whether from the crashing of something that unexpectedly falls, to thunderstorms and of course, fireworks. Here are our posts on fireworks:

• Fireworks: Not fun for everyone, or every dog (click here to view)
• What kinds of dogs are troubled by fireworks, and what to do about it (click here to view)
  

One of the main points is: There are ways owners can help their dogs:

• In one study, nearly half of the owners surveyed reported that their dogs were frightened of loud noises. Noise phobia can show itself through both freezing (catatonic) as well as panic (excessive movement) behaviors.  

• Most owners of dogs showing fear behaviors in relation to loud noises reported that they were unaware that professional help (from animal behaviorists or veterinarians) was available to help. And owners had not not pursued such help.

• Classical counter conditioning can help dogs change their emotional state, and thereby, change their outward behavior. Here is a video, by veterinarian Sophia Yin, showing a dog learning that nail clipping is not so bad. The same thing can be used for loud noises like fireworks and thunderstorms. 

• Our earlier posts provide even more suggestions for changing dog emotional states and help dogs be calm and less anxious when exposed to loud noises.

I hope that by talking about this topic often, people realize that they can help dogs decrease their displeasure with loud noises. Or, possibly even work preventatively and help dogs from developing negative associations with loud noises in the first place!

Bye for now!

Julie
