Modification of our trash handling:
We were quite happy with the stock solution, where there's a drawer like door which opens up to a one-bin system for the trash. As you can see in the picture, it's quite large and high, which is good.
However, the upper wooden frame is smaller at the top, than the bottom. So when you fill a bag with trash, and then try to remove the bag, the stuff at the bottom get stuck below the upper frame. This is not a big thing, and not the main reason why we changed it.
In today's world, and in the passage-making world , sorting your trash is important and essential for several reasons. Inshore, it is important to sort our things for recycling. Offshore it's important to sort things for "legally/environmentally dump" vs. "keep aboard".
Most people grasp the inshore thing. So won't spend time on that...
Modification to a two-bin system:
We removed the upper wooden frame and replaced it with simple plywood dividers. A smaller space for a paper bag, and a larger space for a plastic bag.
Now we can sort our trash!
Offshore trash handling:
Offshore, and more importantly, when passage-making , handling of trash gets very important. You just do not want any smelly stuff aboard, especially when in tropical climate. The good part is that most smelly stuff is biological, and legally and morally OK to dump overboard (offshore). So it's important to separate these things while sailing.
There are a lot of non-smelly things that's OK to dump as well, as paper. Then we get into the legal, but in our opinion questionable things. Like cans (non aluminum), and glass, which is legal to dump, but maybe not a good idea.
So, we separate everything that can be dumped in the forward "paper-bag" part of the trash bin, and all "keep aboard" things in the aft "plastic bag" part of the bin.
When the paper bag is full (or smell), it's dumped over board. When the plastic bag is full it's stored (knowing there's no smelly stuff in it).
