Many of our 2020 camp experiences have been postponed due to the Covid-19 virus. We look forward to continue the gatherings when it is safe to do so. Please check our website or subscribe to our newsletter for the latest updates. We commend the efforts by so many of us to limit the spread of the virus and send deep thanks to the healthcare workers across the globe taking care of those most affected. We see our work of bringing balance back to ecosystems as more important than ever. Our team is busy building our organizational capacity during this time so that we can share the message of regenerative land management even further. We are grateful for your support and look forward to seeing you at camp in the future.

Home Composting: a Simple Practice Towards Eco-Friendly Living

Composting is a simple and effective way to live a greener lifestyle, and for those with a garden it is also a great way to produce top quality plant food at absolutely no cost! The internet is full of useful resources that explain the key points of effective composting (links to some great sources are provided later on), but for many people the specific benefits of composting, and the extent to which it really makes a difference, remain a mystery. This brief overview will explain what compost is and how it benefits ourselves and the planet.

What is compost?


Compost is just organic material going through the natural process of decomposition: that is, being turned into soil by worms and/ or microbes. By putting the organic material (i.e. food scraps and garden waste) in a compost bin we create a favourable environment for worms and microbes, as a result they grow in number, and the process accelerates. This process is identical in worm farms.

The key difference between worm farms and compost bins is that worm farms are closed at the bottom, so some soil and worms must be added initially to get the process started, and they need to be monitored a little more closely. A major advantage, however, is that the liquid run off, which is extremely nutrient rich, can be captured and used as fertiliser. Worm farms are a great option for people who live in apartments, or only have small gardens.

There is no doubt that composting produces the best garden fertiliser, but for many of us, particularly city dwellers, that’s not a major consideration. The next section will explain how composting can hugely reduce both the amount of waste we send to landfill and the contribution of our kitchen scraps to climate change.

 

The benefits of home composting


There are great benefits from having a compost bin or worm farm. The first thing you will notice is a huge reduction in the amount of waste that ends up in the kitchen bin, and this has a bigger impact than you may realise. According to the World Bank, cities globally generated roughly 2.01 billion tonnes of solid waste in 2016, and up to 44% of this was food and organic material! Although not all of this came from households, it is clear that composting can greatly reduce the amount of waste that goes to landfill.

Diverting food waste from landfill is also the main way that composting reduces the impact of our household bin on the climate. The breakdown of organic material releases both carbon-dioxide and methane, but the ratio in which these gases are produced depends on the environment the material is in as it decomposes. This is critical, because methane is roughly 26 times more potent as a greenhouse gas than carbon-dioxide.

Food waste that goes to landfill breaks down anaerobically (without oxygen), and as a result releases a relatively high ratio of methane to carbon-dioxide. A well-managed home compost pile, on the other hand, can largely avoid not only the methane emissions associated with the decomposition of food waste, but also the fossil fuel emissions required to transport it to landfill. This means composting is a great way to reduce the carbon intensity of our kitchens.

For those that do intend to use their compost on the garden there are further benefits. First of all, good compost is an excellent fertiliser. More importantly though, it not only alleviates greenhouse gas emissions associated with producing and transporting artificial fertilisers, but it also prevents chemicals from being washed into the waterways and oceans

So even if you don’t grow your own food, or aren’t a particularly avid gardener, composting reduces the amount of waste that goes to landfill and its associated greenhouse gas emissions. Beyond this, composting also restores elements to the natural cycle, which is a positive outcome in itself!

 

How to compost


As well as being a worthwhile, eco-friendly activity, composting is also incredibly simple. There are some important points regarding what to include, and balancing food scraps with garden scraps, but the key is to not overthink it. This easy to follow three-minute video from Gardening Australia’s Costa Georgiadis has literally all the information you need to get started, and features Costa’s magnificent beard:

 

For those who want to know more about the specifics of composting, Gardening Australia provides a useful fact sheet

At the end of the day, remember that what you put in to compost was going into the bin
anyway. Even if it doesn’t work perfectly straight away you can always address issues as you
go. Good luck – and please share your experience of setting up a home composting pile in the comments!
