Around 90% of greenhouse gas emissions from landfills are a result of decomposing organic material which could be diverted. Composting garden materials and food scraps diverts this organic matter from landfill. Compost Week

Composting Tips

What is Composting?
Composting is the natural breakdown by microbes of organic material to a dark, loose and 'earth-like' substance.

A composting system confines the organic material and often controls the conditions in the material so that the breakdown is accelerated. A composting system can be started in old garbage bins, wooden boxes, or in a simple heap.

Why Compost?
Today there are several different reasons why composting remains an invaluable practice. Garden and food wastes make up a large portion of the material thrown out in Australia. Much of this waste could have been avoided from landfills through simple composting methods. Compost added to gardens improves soil structure, texture, aeration, and water retention. When mixed with compost, clay soils are lightened, and sandy soils retain water better. Mixing compost with soil also contributes to erosion control, soil fertility, proper pH balance, and healthy root development in plants.

How to Compost
Composting is easy. Common materials like chicken wire, bricks, and buckets are all it takes to begin a composting bin, or they can be purchased for as little as $20. There are four key words to remember: green, brown, air, water. To make compost, all you have to do is bring together moist, fresh, predominantly green ingredients (grass clippings, weeds, kitchen scraps, and the like) and predominantly brown ingredients (dead leaves, straw, hay, wood shavings or chips, etc.), ensure that the mix remains damp, and turn it all every few days to reintroduce oxygen to the pile. That's it. In less than a month, you'll have rich, crumbly, brown compost that you can add to your garden soil, use in containers, or mulch with.

Environmental Benefits of Composting
Composting makes sense. Instead of sending organic matter to a landfill, it can be transformed into a useful additive to soil for potted plants and gardens. It has numerous environmental benefits as well:

  • Compost has the ability to help regenerate poor soils. Compost has also been shown to suppress plant diseases and pests, reduce or eliminate the need for chemical fertilisers, and promote higher yields of agricultural crops.
  • The composting process has been shown to absorb odors and treat toxins. It has also been shown to bind heavy metals and prevent them from contaminating water resources or vegetation and getting into the food chain.
  • Compost has also been shown to prevent erosion and silting on embankments parallel to creeks, lakes, and rivers. It also prevents erosion and turf loss on roadsides, hillsides, playing fields, and golf courses.
  • Using compost can reduce the need for water, fertilisers, and pesticides.
