Went to a local store to buy a soda bottle and cartridges. I like bubbly water from time to time and thought I could make my own. Alas, what I discovered to my dismay was that the cartridges were not refillable. What’s the point, I asked. At least I can recycle bottles.
I remember my mom sending me to the store to return used soda cartridges and to buy fresh ones. If one returned used cartridges one did not have to pay a deposit. Is that still how it is done in Europe or other U.S. states?
Most natural food stores sell bulk, e.g. grains or olive oil, and a few weeks ago I thought it would be nice if somebody sold a stainless steel container that would hold a certain amount of liquid or dry weight. There would be no need to get the container pre-weighed as it would display its empty weight on the container. Stainless steel can be scrubbed and cleaned and does not break. One can always pour the contents into a “display” container at home.
By the way, I clean my steel water bottles and coffee mugs with a little white vinegar. Afterwards I simply rinse and dry and the stale, old coffee smell is gone.
