I don't think guests are ready for this level of sustianability just yet Maree. Guests will even mark you down if they feel that soap has been previously used or tampered with in any way. By cutting soaps down you will be seen as a 'cheapskate' host, not an environmentally conscious and friendly one. I offer a full boxed cake of soap for every guest, even overnighters, and because it come to them in a sealed box I encourage them to put it in their bags when they leave for them to use another day....and most do!
Guests like things sealed when they get them, even that jar of Mocona coffee, they actually prefer the sealed one serve packets. My only concession to dividing up. I have the ability to make bubble packs for various smal serve things and I cut blocks of good quality certified organic butter up into three or four serve blocks and seal them in bubble packs and guests accept that ok. If it looks like it has come from the licenced manufacturer it's ok, if it looks home prepared, it's not! Besides, that 5 or 6 pieces of bacon you remove from the sealed 1 Kg pack and put in the guest fridge will contravene local health regulations if you are serving to paying guests.
I am possibly as environmentally conscious as you, we produce all our electricity from either solar or wind and are net exporters back to the grid, We harvest and use our own rainwater most of the year with storage tanks and pressure pumps which use the electricity that we produce. I think I have a pretty small carbon footprint, but Maree, I admire your enterprise and five years time you will probably have a reasonably large following, I think you are just a bit ahead of your time.
