In Croatia, it is ignored that waste water can be used for the production of heat and electricity. Nowadays, organic substances and chemical compounds from waste water are already abundantly used. However, during the year there is also a high degree of poorly used thermal energy in waste water.
When water is used in households, the economy and industry, warming occurs. Instead of releasing the unused generated heat together with waste water into the environment, it is possible to use it to a considerable extent for heating buildings or other purposes.
In Croatia, there are various afforestation actions, but they are mostly done by hand with the production of seedlings, and they are slow and give less impact than they could. For just one square of forest, it is necessary to plant a seedling several times and inspect the field several times after the seedling has been planted, to see if the fruit has been received.
With technology, they would speed up the whole process and thus plant more trees and reduce the climate changes that are already happening to us
In Croatia, there is interest in renewable energy sources, but their use is still underrepresented. Nowadays, there are various projects that promote the use of solar panels, hydroelectric plants and wind turbines. However, the problem is that they are still underused.
Instead of using renewable energy sources and storing the remaining energy for other needs, “disposable” fossil fuels are used, which have a negative effect on the environment.
