Hello and welcome to The Compost Bin. I'm Compostwoman and I live with my family in rural Herefordshire. We have nearly four acres of garden and woodland, all managed organically and to Permaculture principles, which we share with Chickens, Cats and assorted wildlife. We also grow a lot of our own food, run courses in all sorts of things and make a lot of compost!

I am a Master Composter and have spent more than a decade as a volunteer Community Compost adviser with Garden Organic and my local Council.
I'm a self employed Environmental Educator so I run workshops and events where I talk about compost, veg growing, chicken keeping, cooking, preserving and sustainable living. I also run crafts workshops and Forest School/outdoor play sessions in our wood.

We try to live a more self sufficient lifestyle here, as best we can, while still having a comfortable life and lots of fun.

HotBin Trial Days 2, 3 and 4

Day 1 (recap) Fri 6th July 2012

HotBin filled with a mixture of week old material from an existing compost bin, fresh weeds, cut nettles, hay and guinea pig droppings and paper scraps.

The ambient temperature was 18 Celsius when I filled the bin mid afternoon on a sunny but cool period during a showery day. After less than an hour the top temperature gauge read 40 Celsius ( reading the air temperature at the top of the HotBin) and the top layer of material inside the HotBin was at 25 Celsius.

Day 2 (recap)  Sat 7th July 2012

After 24 hours it had all slumped as the the material started to decompose.

After 24 hours the top layer of material was at 40 Celsius and the lid thermometer read 50 Celsius with an ambient temperature of 20 Celsius.

According to HotBin, this is a "textbook start"

Day 3 Sun 8th July 2012

Contents now steaming gently and when opening the lid I could feel a blast of warm air on my hands,
When taking readings the ambient temperature a cool 13 Celsius  and it was dull and rainy - not very summery weather!
Lid thermometer reading 45 Celsius.
Internal thermometer ( inserted about 10 -15 cm into material same reading regardless) at 50 Celsius.

Day 4 Mon 9th July 2012

LOTS of steam on opening the lid! Material slumped even more.

Internal temp at 60 Celsius!Yay!

Ambient temp. 16 C
Lid temp 48 C
Internal temp middle of box @ 10 cm down into material 60 C

(readings taken at 1100)

At 1800 the internal temp. was 65 C in the middle, @10 cm down and the internal temp. 2 cm from the edge, @10 cm down was 62 C.

It's hotting up in there!
