WHAT IS COMPOSTING

Composting is a natural way of recycling organic waste into a valuable material for improving soil. It is a complex process of biological conversion resulting from the activity of naturally occurring microorganisms operating in highly variable heterogenic materials. It requires careful management of a number of key parameters to produce a high quality end product.

WHAT MATERIALS CAN BE COMPOSTED

  • Food Waste

  • Garden Waste

  • Organic Fraction of Mixed Municipal Waste

  • Agricultural and Horticultural Organic Waste

KEY COMPOSTING PARAMETERS

The following parameters need to be assessed and controlled to produce quality compost:

  • Particle Size <200mm

  • Carbon/Nitrogen Ratio 30:1

  • Moisture Content 40-60%

  • Oxygen levels >12%

  • pH levels 6.5-8.5

  • Temperature 55℃ for 15 Days

TYPES OF COMPOSTING SYSTEMS

There are two main types of composting systems

  • Open Windrow Composting: The material is composted outdoors on concrete pads. It is formed into long high triangular rows and turned regularly.

  • Enclosed/In vessel composting: The material is composted in sealed chambers, normally tunnels. This system allows for better control of composting conditions.

BENEFITS OF COMPOST WHEN APPLIED TO SOIL

  • Increased Soil Fertility

  • Improved Soil Structure

  • Increased Soil Water Retention Capacity and Soil Microbial Activity

  • Reduced Plant Failure
