Best Sustainability Practices in Events Case Study: “Na Praia,” Brasília, Brazil

This research work aimed to present sustainability practices directly linked to actions related to water resources during an event in Brasilia, capital of Brazil. A case study of the annual event called “Na Praia,” which had five previous editions, has been carried out. This event obtained a Zero Waste certification issued by the Zero Waste Brazil Institute once it reached up to 95% of waste recycling in the last three years. The event can contribute to the preservation of the water quality of Lake Paranoá, which is a water supply source in Brasília. To this end, the UN's 17 sustainable development goals (SDGs) are used as a guiding instrument. Seventeen goals are employed to achieve the general sustainability plan of the event and six goals are directly or indirectly linked to water resources: clean water and sanitation (water savings and reuse); affordable and clean energy (solar energy for the store and mobile phone charging); responsible consumption and production (use of electric hand dryers and water soluble toilet paper); climate action (carbon emission reduction, planting trees); and life below water (reduction of plastic use at the event, 100% oil recycling of used kitchen, taken from the garbage of the bottom of the Lake Paranoá). Since 2017, 350,000 m² of native trees have been restored in the Descoberto River Basin.
