Learn a little about its composition, effects and ways of recycling. What really is Styrofoam? Its technical name is Expanded Polystyrene (EPS), and it is actually considered a type of plastic that comes from petroleum. One of its main characteristics is that it is made up of 98% air! It is very present in the cities since it has a great quality-price ratio. because it is not welcome In addition to its non-renewable source, polystyrene is a type of plastic that does not degrade in nature, it only fragments into smaller particles, making its ingestion dangerous for birds and marine animals. Once infected, these animals can also infect humans if consumed. What can it be transformed into? Mechanical recycling: it is the most common. It transforms polystyrene into raw material that can replace wood, for example, in the case of picture frames, skirting boards and toys. In addition, this process reduces deforestation (every 300 tons of polystyrene recycled per month prevents the loss of 5 thousand trees)! Oh, and you can also make hangers, pens, and CD covers.
In civil construction, it can even be transformed into an input for lightweight concrete, coatings and walls. The first step in recycling is to remove the air from inside the polystyrene with a compacting machine, generating a type of very dense mass (similar to bread). This mass is crushed, then heated and finally the final material is ready to be transformed into the objects described above. Energy recycling: polystyrene has a high calorific value and can generate energy. When burned in thermal power plants, it emits water Uruguay Mobile Number List vapor and carbon dioxide, being little harmful in this sense. Chemical recycling: transforms polystyrene into glues, solvents, gases and oils. Why is it difficult to recycle? The problem is with transportation. Many companies and collectors are not available to collect polystyrene waste because it is very light and takes up a lot of space. That is, to transport a large amount of polystyrene, for example filling a truck, very little raw material is produced at the end of the process, which makes recycling unfeasible. And buying a machine, for example the one that removes air from polystyrene, can also be expensive: it costs on average 70 thousand reais.Flying rivers? What are they? Flying rivers are enormous masses of water vapor in the atmosphere that move between regions, providing moisture wherever they pass.
This phenomenon occurs very intensely in the Amazon rainforest and in this post you will read why this is so, about its importance and how they are susceptible to human actions. Why are they common in the Amazon? Due to the enormous number of trees... They extract water from the subsoil and, through evapotranspiration, spread a large amount of water vapor into the air, forming flying rivers. According to the INPA (National Research Institute of the Amazon), a 10-meter tree emits 300 liters of water in the form of vapor into the atmosphere per day! Adding up the evapotranspiration of all the trees in the Amazon, we basically have an Amazon River… just in the air! It is important to remember that before the effect of the trees, the flying rivers are born in the Atlantic Ocean and reach the forest through the trade winds. Masses of vapor soon take shape and intensify the phenomenon. Where are they going? What are the consequences? As soon as water vapor reaches the Amazon atmosphere, it returns to the ground as rain or is transported by air to other regions through winds. In the case of the Amazon, part of it moves towards the west of the continent, reaching the Andes Mountains, where it precipitates in the form of rain or snow, supplying sources and river courses that give rise to the Amazon River itself.
