  • Composting glycerine

    Good morning everyone,

    as this silliness is spreading, a lot of people in the area have rediscovered the old veggie patch.

    I have been composting most of my glycerine over the last 2 years. With I think great results.

    I have got 2 compost heaps, about 1m3 ea. The glycerine gets applied in a thin layer, them covered with straw, mulch or grass clippings. Twice a year the composting toilet gets emptied there as well.
    Next layer and so on. The compost has a beautiful dark rich colour and smells like good compost.
    It is important to not put too much glycerine on at anyone time as this will end up as a smelly mess.
    I often also use saw dust from work to absorb the glycerine and stop it from running everywhere.

    My compost heap always sits around 55-60 degrees, which should kill off any harmful bacteria. As my first compost heap approaches 2 years, I am about to use it in the garden.
    When I checked it yesterday, it was full of worms, I will keep you posted on the results.

    My recent addition to the garden where 2 banana plants. Somewhere I have heard that Bananas like potassium fertiliser. Has anyone of you applied glycerine as a weak brew or direct in small doses to Bananas?

    have a great day!

        Years ago I heard , the money is in the junk end of the business . Turning waste into a useful product is an example of that . Purified glycerine can be made into glyceryl triacetate , which can be used and is worth money . I don't know about calculating the economics of making it , cost versus production of revenue . Seems a shame to compost it , when it might turn a profit . A formula for glyceryl triacetate is glycerine + glacial acetic acid + catalytic amount of concentrated sulfuric acid + heat to produce glyceryl triacetate plus water . Then purify
