Cascais launches €550,000 tender for green biowaste bags

Cascais's municipal environment company EMAC has opened a public tender worth €550,000 to buy green polyethylene bags for collecting biowaste across the whole municipality. The bags let residents mix food scraps and other biodegradable waste into the same bin as regular rubbish; optical readers at the Tratolixo plant later identify and sort them for recycling. The scheme began as a 2018 pilot in Carcavelos and Parede and expanded to cover all of Cascais by 2023. In 2024 over 70,000 households, about 90% of the population, took part, generating nearly 3,500 tonnes of collected biowaste.
