The challenge was very simple: a good mood, a lot of will to do more for the planet, and a smile on your face.

Persistent rain and fog accompanied the group of 30 people that last Saturday - the 1st - and in only 2 hours, collected more than 16 kg of residues in one of the most beautiful beaches of the Lisbon region.

Guincho Beach welcomed with open arms the friends and partners who wanted to join the walk for sustainability and served as a stage to start the KAFFA - Guincho Outdoor partnership that, in this first initiative, donated more than 100 burlap sacks for waste collection.

Burlap sacks, due to their properties, are perfect for this type of activity. Being a reused and eco-frendly product, it is also a powerful natural sand and soil filter, allowing only residues and micro-residues to be retained inside.
