Don't worry about disposing of your old salt because there are several ways to do this. Our first suggestion is that if there are weeds around your habitat, salt, which is not suitable for the plants' chemistry, will kill them. Thus, you can get rid of weeds in a short time to re-green your gardens. Do not forget to allow up to a month for the soil in that area to plant new plants. Our second suggestion is that you can melt your hiking trail covered with glaciers in winter with the help of this salt. Sprinkle on the ice road and wait for it to melt. Finally, it is okay to throw away the old salts in the trash, so put them together with your other rubbish and throw them away.
