Garden waste collected at the kerbside is taken to a composting site where the garden waste is turned into a nutritious soil conditioner which increases the nutrients and improves a soil's structure to help plants grow. This can then be used for land reclamation, agriculture and as an ingredient in some multipurpose composts you can buy at a garden center.
How is garden waste recycled?
When the garden waste arrives at the composting site any material that is not compostable is removed, the remaining garden waste is then shredded and then laid out in a long pile to decompose, usually in the open air.
The process at a composting site is similar to that that takes place in home compost bins, but is actively managed to speed up the process. However, due to the amount of material the temperature reached is a lot higher than in a normal household compost bin temperature. Temperatures can reach up to 60°C These higher secondary temperatures mean that the enzymes and bacteria are quickly put to work resulting in a finished composting process in just a few weeks.
The composting material is turned frequently to provide much needed oxygen to micro organisms that help decompose the material. High temperatures can kill off any harmful microbes, weeds and plant diseases.
The final part of the process involves screening the compost to remove any remaining contaminants and to grade the material for various end uses in the garden. Any composting material that is still oversized or hasn't decomposed enough, can then be put back through the process until it has composted down sufficiently.
The whole recycling process takes between eight and 16 weeks, depending on the final use for the compost.
Instead of making a compost bin we can use a composter vertical garden planter tower which works effectively in the process of making compost.
