    I am considering the option of installing a composting toilet in my cabin and would welcome advice and guidance.
    Having researched various options available to purchase I am considering a system which separates liquid waste and solid material and using airflow through venting allows breakdown of both liquid and solid materials. As an adaption to the system I am considering using a vacuum toilet usually used in boats to allow me to situate the composting system in an area of my choosing which will allow more sunlight onto the collection unit to make it more efficient, though I need to investigate if this would work when combined with the composting system.
    As this is the first time I have installed such a system I would appreciate any advice regarding composting toilets and their installation and if it is possible to build a system myself ( I ask this question as I have viewed some very informative videos online)
    Thanks Andrew.

    There are at least a couple of CT users over on the Navitron forum. You might find this topic especially interesting:

    We have a perfectly good WC to septic tank, but inspired by that topic I've been doing a bit of experimenting over the last few months! I started with thewww.humanurehandbook.com approach (i.e. all in one). That was fine, but you go through prodigious quantities of sawdust and a full 25l bucket is quite a weight to handle - not the sort of thing you'd want to stumble with on the way to the compost heap. I've now moved on to a hybrid separate & cover approach, i.e. solids in bucket, with sawdust cover, liquid elsewhere (5l bottled water flagons are very handy...). That's okay but doesn't seem to be as effective at odour control, perhaps because you tend to use much less sawdust? So, the next stage is to move the experiment on to separation with forced ventilation/desication, as used by the couple mentioned in the Naviton topic.

    PS. One "green" aspect of these systems I don't recall seeing mentioned is that if the loo is within the insulation envelope there's an associated reduction in heat loss, i.e. you aren't bringing in cold flush water which absorbs heat before being flushed away, along with a quantity of additional body heat material...

    Of course if you're using the forced ventilation approach there'll be some loss of heat associated with that, but any cistern with an overflow probably has at least a bit of a draught too?
