Home composting

Home composting is the most environmentally friendly method of dealing with organic waste. Most food and garden waste can be recycled back into the soil, via composting.

Composted organic material can be used to provide plant food and improve the quality of the soil.

The tidiest and quickest way of composting is to use a compost bin. Home compost bins are available from most DIY/garden stores.

What is composting?

Composting is a natural process that converts organic waste into a valuable material for the garden.

  1. Bacteria and fungi (the 'heaters'), use the softer wastes as a source of food. A well-made heap should generate heat and reach 60°C - about the temperature of a hot cup of tea. 
  2. The heap will cool down after 4-6 weeks and at this point worms, centipedes, beetles etc (the 'chompers') start consuming the tougher material.  A dark, rich, fibrous compost is then produced.

Why should we compost?

The benefits of composting at home include:

  • A reduction of waste going to landfill sites.
  • Financial savings.
  • Most pre-packed compost contains peat, which when removed from peat bogs damages important wildlife sites.
  • Improves the texture and the nutritional quality of the soil.
