Tackling Microplastic Pollution from Paint at the Source

Microplastics from paint residues and household activities are an increasing environmental challenge. According to studies commissioned by the Swedish Environmental Protection Agency and Svenskt Vatten in 2016, paint wear and washing are recognized sources of secondary microplastics entering waterways and marine environments . When brushes are rinsed directly in sinks, tiny plastic and pigment particles pass into wastewater streams, placing an additional burden on treatment plants which, despite high efficiency, still release microplastics into the environment.

Lavabrush introduces an innovative solution for professional painters and craftsmen – a system that cleans brushes effectively without allowing microplastics and paint residues to enter the sewer system.

The Challenge

• Paint residues are a significant source of secondary microplastics.
• Households and small businesses often rinse brushes in sinks, causing particles to reach wastewater treatment plants and eventually rivers, lakes, and seas.
• Treatment plants remove 80–95% of microplastics, but remaining emissions can still cause severe local environmental impacts.

The Solution – Lavabrush

• Captures paint residues in a closed container instead of flushing them away.
• Saves water – up to 99% compared to manual rinsing under running water.
• Protects the environment by preventing microplastics from reaching sewer systems and treatment plants.
• Extends brush lifetime, reducing resource consumption and waste.

A Step Towards Sustainable Practices

“The report highlights the urgent need for upstream solutions to reduce microplastic emissions. Lavabrush is exactly that – stopping pollution at the source before it reaches our waters,” says Johan Palm, Lavabrush.

With Lavabrush, the painting industry gains a unique and practical tool to contribute to national and European goals of reducing plastic pollution in aquatic environments.
