How to contain trash/waste food smells? After using certain foods e.g. fish, spinach the remaining trash/waste food starts to smell and my tiny flat starts smelling of fish etc.  I cannot take the rubbish out daily and if I put them in plastic bags I notice the smell keeps coming out, maybe these bags are porous.

I'm thinking the best thing is to put them in plastic containers and take them out once a week.  Any ideas?  If I get those small plastic bags with air tight written on them will that be sufficient to contain any smells?

In the same light, when putting foods inside a fridge/freezer is there a specific type of bag one should use to ensure odours do not travel.  I notice that some refrigerator bags are so thin they might not actually contain smells?
I put potentially malodorous food scraps in the trash if I know I will have enough to take the trash out that day (I hate wasting trash bags, blame my OCD). If not, I will put scraps in freezer bags and leave them in the fridge temporarily. The difference between freezer bags and regular plastic bags is they are much thicker and tougher. If you get a good quality bag the zipper part seals air-tight and the plastic will not breathe. The key here is don't be cheap: You get what you pay for.

Freezer bags easily hold in odors for several days until you have enough for a load of trash to take out to the dumpster.
