On 16 July 2025, a lecture was held on Selective Waste Collection and the 5 Rs of Sustainability, involving 41 CV3 trainees in Industrial Maintenance Electricity (10 women and 31 men) at the Dom Bosco Higher Education Institute in Maputo, Mozambique. The session took place from 2:30 p.m. to 4:00 p.m., with the aim of raising environmental awareness.

In the first part, the concept of selective collection was presented, highlighting its importance for public health, the environment, the economy and society. In the second part, the 5 Rs of Sustainability (Reduce, Reuse, Recycle, Refuse and Rethink) were explored with practical examples, such as: waste separation, bottle reuse, reduction in the use of plastic bags and the valorisation of recyclable materials. The activity encouraged responsible attitudes and everyday environmental practices.
