good morning from Olympic city of London

today i have collected what i consider the rolls royce of  composting material . straw soiled by farm animals.  i have incorporated this to my existing chamber mix. from past experience this should raise the temperature within a few days.   

Sunday, 29 July 2012

this morning i have rotated the chamber and a bit disappointed that the temperature has not reached 40c but had dropped down to 30c

this week i will be using some of the compost to feed my plants  as bananas and brugmainsia  are heavy feeders and will benefit from a good mulching with warm compost.

i will visit the local vauxhall farm in the week and collect soiled  straw to place in the chamber as this produces higher temperatures from previous attempts using it

this past week i have been adding vegetable waste from the local deli on the corner of the square i live in.

my composter is now just over half full . the temperature is 34c

it has become a little bit difficult to rotate as it is heavy. i will be asking my neighbour for some muscle power to help me rotate this next few days

i am still hopeful i cn achieve temperatures above 40c this next week

today the temperature in chamber was 30c

i spent the day weeding one of my neighbours gardens and collected lots of weeds which have filled up the drum. as it had been raining in the morning the weeds are very wet . all this has been mixed into the compost and i expect temperatures to start rising again in the next few days. hopefully above 40c

today on checking the temperature 30c

i have collected my first lot of vegetable waste from the local cafe . and as it was in a cardboard box the whole lot has been put into the chamber.

i also explained that they can add coffee, and any tissue paper to the waste too, hopefully i should be able to fill the chamber up over the next week and raise the temperature above the 35c

today as i rotated the drum it was a pleasure to see steam rising out of the chamber. i have noticed the my compost has been reducing in mass. and need to source out more organic matter to keep my Bactria feeding and gaining more heat.
the local Italo Deli in Bonnington Square are kindly saving me their organic waste to add to my compost. i may even have to ask some neighbours   to help too.

have added more cardboard  today to absorb excess moisture as getting the right humidity is all done by eye.  this year i have been adding more cardboard than previous attempts.

the temperature was 30c . i suspect the drop is due to the mass of compost that has dropped .

i am only using vegetable waste cooked /uncooked so far as adding meat is possible but not until i have a constant temperature above 60c

Saturday, 30 June 2012

am up early today

the temperature in the compost is 37c getting close to the first target of 40c which is impressive as the majority of the mixture was sitting in the chamber for over a year and was very wet and at first i thought i would have to remove it. By simply adding dry cardboard to the mix and rotating the drum constantly the cardboard has soaked up the extra moisture has given the right conditions for the Bactria to get working.

i have been adding my own food waste to the mix everyday and had a small bag of grass clipping into it .however i will have to pay a visit to Vauxhall City Farm and get1/2 a barrel of there lovey farmyard muck to add some bulk to the chamber as its very noticeable how much compost has been consumed.

the guide is one part green waste to 2 parts brown waste

the exta bulk in the chamber should raise the temperature to a level to kill of harmful pathogens.
