Homemade whipped cream requires beating heavy cream on high speed for several minutes until the cream forms peaks, but this process is anything but convenient if you simply wish to add a bit of cream to a dessert or beverage. Aerosol whipped cream containers make whipped cream convenient and easy -- you simply squeeze the nozzle and fresh whipped cream is available without mixing required. The liquid cream inside is under pressure, which can be dangerous if you simply throw the can into the trash.
Hold the whipped cream can upside down over a sink or dessert and push the nozzle to squeeze out any remaining cream.
Rinse the nozzle and sides of the bottle with warm water to remove any cream residue so the container is clean upon disposal.
Add the empty whipped cream container to your recycling bin or weekly garbage. Many recycling centers accept nonhazardous aerosol cans such as whipped cream cans as long as the cans are empty.
