The historic centre of Sarriá represents an ideal setting for the development of the first door-to-door waste collection system in the city.

Over ten years ago Barcelona, the first among the large cities of the separate waste collection, activated the separate collection of organic waste. The percentages of separate collection achieved are considerably higher than in the rest of Spain, nevertheless the aim is for a further improvement.

Contarina, a utility that deals with waste management in the municipalities under the Consorzio di Bacino Priula, and Ascotrade, a gas and electricity supply company, promoted the initiative “Collect used oil and save on energy bills”.

“Differenza in Comune” is the name chosen to describe the new door-to-door separate waste collection project which, starting from 2018, involves the Municipalities of Valle Sabbia.

The mountain community of Valle Sabbia decided to educate the population in terms of separate waste collection.

Sartori Ambiente collaborated as a partner in the initiative, providing the necessary equipment.

The island of Pantelleria is a reality which, given its tourist and geographical peculiarities, needed a strong change in the methods and performance of waste management.

Parma is one of the most virtuous examples in Emilia Romagna, a region at the bottom of the waste generation ranking with 667 kg per inhabitant per year. The transition from traditional waste management was the result of a clear political will: a careful and widespread involvement of citizens and a strategy focused on minimizing residual waste.
