A problem of longer passages is just how to address the problem of the accumulation of rubbish, mainly from plastic food packaging. This can be bulky and inevitably becomes smelly in the warm conditions. We came up with a novel solution to both seal and compact the refuse so that it could be stored flat in the bilge pending disposal in the Caribbean. We used a home-made adaptor which slotted into the end of a re-chargeable vacuum cleaner and cheap vacuum storage bags. Simple !
Great idea, soon to be adopted byat least one other. This may be a commercial solution. Some googling to do.
