WOOD CHIP – Bulking Agent

COMPOST BULKING AGENT – WHAT IS IT AND WHY DO I NEED IT? 

We have already mentioned a little bit about Bulking Agent in a previous post and STRESSED that it is an essential part of the HOTBIN composting mix. It aides hot composting by helping to retain a structure which helps get oxygen that the bacteria.

You need to add bulking agetn (wood chip) when you are composting ALL food waste but it never goes amiss if you are trying to boost those temperatures into the hot composting zone between 40-60 C.

SO WHAT IS A COMPOSTING BULKING AGENT?

Well it is simply composted wood chip. Basically raw wood chip that has been left in a pile for six months. It has the advantage in that it will have bacteria on each chip which will mean it acts as a natural accelerator too.

CAN I USE RAW WOOD CHIP?

Yes, you can use raw wood chip. It will still create the necessary aeration structure to allow the chimney effect needed to supply the bacteria with vital oxygen. Those that have been feeding in their shredded Christmas tree have noticed that their HOTBINs have achieved good temperatures due to improved aeration!

The HOTBIN with extras comes with a 25L starter bag of composted wood chip so there is no delay in getting started once your HOTBIN arrives. We estimate you will use at least 75L  of Bulking Agent or Wood Chip every six months.

Remember you can easily make your own or find out from your local council if you can get your hands on some for free.
