Our organic peat free compost is made using the open windrow composting process...
Organic Peat Free Compost...
Open windrow composting is an eco-friendly process for recycling garden waste, eg grass cuttings, tree timber, prunings and leaves, into a wonderful organic peat free compost. It is processed in an open air environment so the materials can break down in the presence of oxygen. There is no food waste in our organic peat free compost, only organic garden waste, oxygen, water and plenty of hard work!
All the garden waste is deposited on the shredding yard for sorting and removal of any contaminated material, which is not suitable for composting.
The remaining garden waste is then processed through a large industrial shredder to reduce it in size.
Depending on the moisture content of the garden waste. water is added to maintain a 60% moisture content.
The processed garden waste is then placed into large prism shaped piles, known as windrows and this is when the organic composting process really begins.
High temperatures between 65ºc and 80ºc are maintained to kill off pathogens and weed seeds.
The waste now begins to naturally heat up and composting process begins, monitoring both temperature and moisture content daily.
The temperature must be kept over 65ºc for at least seven consecutive days, so the heat can generate the microbes and bacteria that will break down the garden waste.
Throughout the two week saniisation phase, the compost must be turned regularly to maintain its aerobic decompostion throughout the windrow.
Lasts for a further seven weeks, actively managing the compost and maintaining temperatures greater than 55ºc.
The temperature and moisture levels of the compost need to be continually monitored each week during this phase and the compost turned at least six more times.
After a minimum period of twelve weeks composting, turning and monitoring, the organic peat free compost is ready for screening to remove all the uncomposted oversize materials.
After screening, the compost is stock piled to mature for a minimum of two weeks before it can be used....
