Castellanza: 273 fewer tonnes of mixed residual waste

In 2025, Castellanza produced 1,895 tonnes of dry mixed residual waste, compared with 2,168 tonnes in 2023. The reduction reported by the municipality is 273 tonnes.

During the same year, the service managed 8,410 tonnes of waste in total, with 6,251 tonnes sent for recycling. The local authority also reports that separate collection stands at 77% in 2026, although its announcement does not specify the exact measurement period.

A result built through everyday action

Behind a percentage are daily choices, but also organisation and clear information. The municipality refers to the work of Aemme Linea Ambiente and to an environmental steward involved in public guidance and monitoring illegal dumping.

The reduction cannot be attributed to one measure alone: the source does not quantify the individual contribution of the steward, information campaigns or the different parts of the service. Instead, the result shows how infrastructure, clear rules and public participation need to work together.

For Un Sacco Pulito, this is the central point: awareness has value when it gives people a simple action they can repeat. This applies to household sorting, public spaces and environmental programmes involving schools, companies and communities.
