What You'll Learn
Volatile organic compounds (VOCs)
The health effects of VOCs are wide-ranging and can include eye irritation, breathing difficulties, headaches, nausea, dizziness, and more severe issues such as kidney damage, nervous system damage, liver damage, and cancer. These health issues can affect those who are exposed to VOCs in their homes, as well as personnel working around paint coatings during the creation and use of paint.
VOCs can also have a negative impact on the environment. They contribute to indoor and outdoor air pollution, which can harm wildlife and plants. VOCs react with oxygen and form an ozone layer in the presence of sunlight, which is thought to be a contributory factor to global warming and air pollution as part of the greenhouse effect. VOCs can also contaminate groundwater and drinking water supply wells, creating additional risks.
To address the environmental and health concerns associated with VOCs, some paint manufacturers now offer environmentally friendly alternatives, such as low-VOC paints. Low-VOC paints improve indoor air quality through little or no odour, less pollution, safer technology, excellent durability, and a washable finish. They can also help to reduce hazardous waste, as the American Coatings Association reports that 97% of all waste solvents from paint and coatings manufacturing facilities are reclaimed for future use.

Lead paint
Although lead paint has been banned in many countries, it is still used in certain regions, such as Eastern Europe and Asia, primarily for industrial purposes like anti-corrosive paint. For example, leaded paint is sometimes applied to roadways and parking lot lines. Lead is a poisonous metal that can cause nerve damage, especially in children, and lead to blood and brain disorders. Lead paint chips and dust can contaminate surfaces and objects that people, especially children, touch and ingest.
The health risks associated with lead exposure are severe, particularly for young children and women of childbearing age. Lead accumulates in the body over time and is distributed to the brain, liver, kidney, and bones. Lead exposure can be through inhalation of lead particles or ingestion of contaminated dust, soil, water, or food. Children are at a higher risk of lead poisoning as they may absorb up to 4-5 times more lead than adults from the same ingested dose. Their natural curiosity and hand-to-mouth behaviours increase their risk of exposure to lead-contaminated sources.
To address the issue of lead paint, the Consumer Product Safety Commission (CPSC) in the United States has implemented protections to ban lead in children's products. Additionally, the US Environmental Protection Agency (EPA) issued the Lead and Copper Rule (LCR) to prevent lead and copper from contaminating drinking water. Internationally, as of January 2024, 48% of countries have legally binding controls on lead paint, and the World Health Organization (WHO) is developing guidelines to prevent lead exposure.
To reduce lead exposure, it is crucial to maintain painted surfaces in good condition and regularly clean them with a wet mop, cloth, or sponge to minimise the formation of chips and dust. If you suspect lead exposure, it is recommended to consult a healthcare provider, especially for children, as they are particularly vulnerable to the harmful effects of lead.

Hazardous waste
Paint waste is a significant contributor to hazardous waste. Leftover paint, if not disposed of properly, can end up in landfills, where toxic chemicals can leach out and contaminate the surrounding soil and water. This contamination can have far-reaching consequences, impacting aquatic life, wildlife, and human health. Even empty paint cans contribute to the problem, as they take a long time to break down.
The painting process itself also generates hazardous waste. During the creation and application of paint, hazardous gases, such as Volatile Organic Compounds (VOCs), are released into the atmosphere. VOCs are emitted from solids or liquids as vapors or gases and can become hazardous air pollutants. They contribute to indoor and outdoor air pollution, affecting air quality and posing risks to human health, including eye irritation, respiratory issues, and more severe conditions like kidney damage and cancer. VOCs also negatively impact the environment by polluting groundwater and drinking water sources.
To address the issue of hazardous waste, the painting and decorating industry has been working towards reducing waste and increasing sustainability. Electronic calculators are now used to accurately estimate paint quantities required for projects, minimizing leftover paint. The recycling of unused paint has also increased, with paint manufacturers reclaiming waste solvents for future use and offering environmentally friendly alternatives. Some countries have implemented paint recycling programs, while others, like China, have introduced taxes on coatings with high VOC levels to encourage the use of low-VOC paints.
The development and use of environmentally preferred paints and coating technologies are also helping to reduce hazardous waste. Waterborne, powder, and high-solids coatings, which have lower solvent content and fewer toxic raw materials, now account for a significant portion of the market. Low-VOC paints, in particular, improve indoor air quality, reduce pollution, and offer safer technology without compromising durability. Additionally, latex paints, which use water as a solvent, are more environmentally friendly than alkyd paints, which rely on volatile solvents.
The industry's efforts to reduce hazardous waste have shown promising results. Between 1995 and 2013, the paint industry reduced its total production waste by 48% and increased the percentage of recycled waste by 81%. While there is still work to be done, the focus on sustainability and innovation in the painting and decorating industry is driving a greener and more efficient future.
