In a typical aerosol can, a propellant (fluid stored under immense pressure) is used to push the packaged product out of the can. This propelling mechanism makes aerosols a cool way of packaging and dispensing almost everything, from insecticides to whipped cream.
Here are some things to know about aerosols.
The first aerosol patent was in 1926
The first aerosol can patent was awarded to Erik Rotheim, in 1926. The Norwegian chemical engineer came up with the original aerosol-can design when looking for the best way to apply wax to his skis.
The technology grew in popularity after World War II
During the Second World War, disease-carrying insects threatened U.S. soldiers in the Pacific. The U.S. military then started dispensing insecticide in aerosol cans. When the war ended, manufacturers liked the easy-to-use cans and embraced the technology.
The world produces over 14 billion aerosol cans each year
People love aerosols. Manufacturers have consequently packaged almost everything in the cans, even medicines. You can then expect to find aerosols in virtually every modern kitchen, bathroom, laundry, shed and garage.
Aerosol cans can be recycled
People who do not recycle aerosols at home incorrectly think aerosols are not recyclable. The truth, however, is that aerosols are made of tin-plated steel and aluminium, and both of these metals are infinitely recyclable materials.
Aerosol cans also contain some rubber and plastic components that scrap metal dealers in Auckland such as Metal Salvage Services Ltd need to extract during the recycling process.
There are many reasons to recycle aerosols
Recycling empty aerosol cans help save energy. Recycling helps reduce greenhouse gases emissions, save resources, and reduce waste going to landfill.
Aerosols are in high demand, and they consequently generate a lot of waste. Luckily, aerosol cans can be easily and safely recycled. As you recycle your aerosols, try to empty all the remaining contents.
If there is still some liquid in the container, dispose of the aerosol through your local hazardous waste program.
