Technology
The aerosol industry has grown from the insect repellant that was used during the Second World War up to what it is today. Insect repellants may still be one of the top products driving the aerosol industry, but there is a wide range of aerosols that are in use today, especially in the cosmetics, drug, personal care, and cleaning industries.
Despite this success, the aerosol industry has, and is still, facing challenges regarding its economic and environmental sustainability. Before the 1970’s aerosol sprays were known to contain ozone-depleting chemicals known as chlorofluorocarbons (CFC).

Today, they use propellants such as hydrocarbons and compressed gases which may not be ozone depleting, but still, they increase carbon emissions and emit volatile organic compounds (VOC). Typically, an aerosol product consists of a container that is a metal, plastic, or glass that is attached permanently to a metering or continuous valve meant to dispense gases, sprays, foam, streams, lotions, and creams.
Environmental sustainability
Being minute particles that are suspended in the atmosphere, aerosols are paramount because they interact directly and indirectly with the earth radiation and climate. They absorb or scatter light back into space, modify the size of cloud particles and are sites where chemical reactions take place. All these have a long-term effect on the environment especially when the levels of aerosol emissions are very high.Inhaling highly concentrated amounts of aerosols is highly harmful to your health as they can cause damage to your kidneys, liver, brain, and cause suffocation. This is why it is important that you only use the recommended amounts of aerosol product, avoid direct spraying, or use non-spray options. The environment is still highly polluted by aerosol cans that contain hazardous products which should otherwise be disposed of as hazardous waste.
To achieve environmental sustainability, recycling tech is now being used in conjunction with proper management and disposal of waste. Apart from this, most manufacturers are formulating products that are VOC responsible like floating roof tanks that reduce VOC emissions and nitrogen blankets.
According to the experts from Signature Filling Company, “The bag-on-valve aerosol system technology ensures that zero harmful substances are being released into the environment. This is a packaging tech that uses a compartmentalized aerosol dispenser and a composite metal or plastic bag attached to the valve body.”
Economic sustainability
A recent tech innovation in the aerosol industry has seen the production of compressed aerosols that use half-size cans for the same amount of aerosol as before. This translates to a smaller carbon footprint per can, less propellant gas and transport emissions, and a smaller amount of material used in making the cans.Counterfeiting in the aerosol industry is also a great concern, but new technologies like patterned varnish, embossing/debossing, and the use of indentation tech has given the aerosols distinctive looks, unique effects, and visual appeal to aerosol cans that had not been seen before.
Recycling of aluminium for aerosol packaging is another metal tech breakthrough that results in a new metal alloy that is stronger and can be made lightweight without compromising the integrity of the aerosol can.
Tech innovations are slowly changing the face of the aerosol industry by making it more sustainable regarding the economy and environment. While the basic principle of aerosol remains the same, other improvements are taking place that make aerosols less harmful to the consumer and the environment in general. This is by reducing g emissions in the air, water, and soil; reliable labeling that provides the correct information to consumers; and balancing the social and economic aspects of product performance.
