The waste that is produced from the filtration consists of pigments that have not been dispersed satisfactorily in the produced paint. This type of waste can be reduced by using filters that can be reused, such as mesh or bag filters instead of cartridge filters.

Moreover, the reduction of the pigments in the final products reduces the produced filtration waste. This can be achieved by improving the dispersion of the pigments in the final product, which will have as a result the improvement of the filter's performance.
