Recycling and renewable energies

Experts believe that the planet will not survive long at the current rate of development. Natural resources that seemed inexhaustible a few years ago are already showing signs of exhaustion.

At the same time, the volume of waste generated increases every day. On average, each Brazilian produces 0.6 kg of waste each day. This represents more than 120,000 tonnes of waste per day. Landfills and landfills are running out of space, increasing the need for an efficient recycling system.

In this course, you will get to know the 3 Rs - reduce waste, reuse whatever is possible, then recycle the rest. Find out how the recycling process for glass, plastics, paper and metals, and more.

Learn how to organize an efficient selective collection and even make money from recycling.

Also find out what the main sources of renewable energy are and how they work. Find out which are the most promising, their main advantages and obstacles. Learn more about solar, wind, geothermal, biofuels, among others.
