The dangers of burning organic materials

Purpose: Packaging materials burn easily in the oxygen of the air. We know that they produce carbon dioxide and water. What other types of products are formed? What danger do they represent?
1. The dangers of burning organic materials
There are three types of hazards when burning these materials:

• fire, if combustion is poorly controlled;
• asphyxiation, if the combustion is carried out in a closed, unventilated room;
• intoxication, if the experimenter is not informed of the possibility of emanation of toxic gases.
2. Combustion: a first danger for the Earth
The combustion of organic materials produces carbon dioxide. Harmful in itself, it poses a major risk for all humanity. Indeed, for the last 40 years, massive combustion of organic matter has caused the accumulation of this gas in the atmosphere. At the same time, forests, the real lungs of our planet, which absorb carbon dioxide through photosynthesis, suffer devastating tree felling. The greenhouse effect, which is very useful in order to avoid excessive temperature variations on the earth's surface, has been amplified excessively thanks to this gas. The average temperature of the globe rises by a few degrees inducing an inevitable climatic disturbance.
3. The risk of incomplete combustion
When combustion occurs with a defect of oxygen: whatever the organic matter, carbon monoxide is produced. This gas is odorless, colorless and possesses the dangerous property of attaching itself securely to the hemoglobin of the blood. In fact, the lungs receive less oxygen. Nausea, headache and asphyxiation are at the rendezvous if the intoxicated person does not receive emergency pure oxygen. Oxygen then restores the balance of gas exchange in the body.
4. The risk of burning plastics
Plastics contain carbon atoms most often associated with hydrogen atoms, sometimes with oxygen. Some of them contain chlorine atoms (PVC or polyvinyl chloride) or nitrogen (nylon, polyurethane). The presence of these atoms in the combustion reagents leads to the production of highly toxic products.
PVC burns by producing hydrogen chloride, an acid gas that dissolves in water to give hydrochloric acid. In incinerators, filters containing a base (soda) can neutralize this acid.
Polyurethane (present in car seat or mattress foams for example) produces hydrogen cyanide, a neurotoxic gas in small quantities. The managers of the incineration centers must set up filter systems to prevent them from being released into the atmosphere.
The essential
The combustion of plastics is not trivial. The products generated are harmful for our planet: both the carbon dioxide that accumulates in our atmosphere and the different toxic gases that we have observed. It is therefore preferable to recycle plastics, minimize combustion of organic materials and filter combustion products.
