I am in the process of building a new motorhome (truck base) and I'm currently investigating options for the toilet system. I'm very interested in composting toilets for their lower environmental impact and time between empties. I'm planning to live in the vehicle and be fully off-grid.
Not keen on cassettes due to their limited capacity. Also, the use of chemicals doesn't thrill me.
Black tank seems like a much better solution than cassettes, but my understanding is you still need to use chemicals in them.
So....... composting. What's the general opinion?
Are they really that simple to use / empty? Are they really odour free? What ongoing costs are associated with them? It seems some recommend putting 'starter material' in the solids container - is this expensive and how long does it last? Is it easy to source?
The urine containers seem to need emptying every few days. Is this true and if so, where do you empty it? I would have thought you'd kill anything you poured it on?
When it's time to empty the solids, where do you do this? I understand the older solids would have turned to compost but given you'd be using this on a daily basis, surely some of the solids are fresh? How do you manage this? Do you need to take it out of the toilet and store it for a period before disposing?
So many questions! I'd be extremely grateful for any help you can provide. This feels like a really big decision to make all on my own!
Thanks so much
